Belts & Pulleys

Belts and Pulleys Basics

Common Terms

Pitch Diameter also known as PD is the circle that is formed while the belt and pulley are meshed together and which the belt rotates around. If you wish to find the PD, reference the formula below.

(Pitch x Number of T) ÷ π

The Outside Diameter also known as OD refers to the outside diameter of the pulley.

Pitch Length also known as PL is the length or circumference of a belt. If you wish to find the PL, reference the formula below.

T x Pitch

The Number of Teeth, T, is simply the amount of peaks that are around the pulley. If you wish to find T, reference the formula below.

PL ÷ Pitch

Calculating Center to Center

How to Use WCP 's Belt Distance Calculator

WCP now offers a built-in calculator to provide all our customers with piece of mind when designing with belts and pulleys. If you are interested in viewing our calculator or knowing how to use it, see below for more information.

You will need a few pieces of information when using the WCP Belt Calculator:

Belt pitch to be used
1. 3mm for GT2/GT3 belts
2. 5mm for HTD Belts
Number of teeth for both pulleys
Approximate distance between centers of the two pulleys

The Output from the calculator will give you the belt center to center as well as the tooth count for the closet belt to the values entered. It will also give you the information for one belt size higher and lower.

Center to Center Equations

The equation below shows the minimum center distance that should be used.

The equation below shows the center distance for equally sized pulleys.

The examples below are places where a looser belt may be beneficial. Subtracting center distance can help reduce the overall load of the system which in turn reduces motor load and power consumption.

First Stage Reduction: -0.000 to -0.003
Intake Rollers: -0.015 to -0.020
Conveyor System: -0.015" to -0.020"

Recommended Applications

GT2 Belts

First stage reductions
Motor to flywheel
Low load

HTD Belts:

Intake or conveyor systems
Drivetrains
Medium load

GT2 timing belts are intended for lower load applications such as the first reduction in a gearbox, or motor to flywheel. GT2 belts use a smaller pitch than HTD belts, which means you can use larger reductions in those tight fit areas of your robot.

All GT2 Pulleys will now be clocked and engraved. An alignment notch has also been added to help with clocking multiple items together during assembly.

GT2 Pulleys

These pulleys are compatible with GT2 and GT3 belts.

GT2 Belts

HTD Belts and Pulleys

Synchronous timing belts are lighter and more efficient than chain. Once set up, they require no tensioning or adjustment. The HTD profile is ideal for FIRST ® Robotics Competition applications - its deep tooth profile allows it to better handle high reversing loads, such as those found in an FIRST ® Robotics Competition drivetrain.

All HTD Pulleys will now be clocked and engraved. An alignment notch has also been added to help with clocking multiple items together during assembly.

Chain Accessories

Master Links Compatibility

#25 Standard Roller Chain

#25H Roller Chain

#35 Roller Chain

How to use Master Links

Master Links are used to form a continuous loop without the need to use a chain breaker tool and have proved to be an efficient quick-release system during repairs and replacement jobs. Using these Master Links is an easy task and can be done by anyone with a pair of pliers.

Slide the Master Link into position on the chain.
Place the Outer Plate on top of the pins far enough as to expose the grooves on the two pins.
Place the clip on the first pin like shown above.
Slide the clip towards the second pin using pliers and ensure that the clip is secure .

WCP offers two types of chain tensions, the Spartan style and the TurnBuckle style.

Spartan #25 Chain Tensioners and Spartan #35 Chain Tensioners are not meant to wrap around sprockets, so use only in situations where chain does not run continuously around sprocket loops.

The #35 Chain TurnBuckle v1 is sized to 3/8" hex and the #35 Chain TurnBuckle v2 is sized to a 1/2" hex.

Gearboxes

Two Speed Gearboxes

Sometimes you just need to use 3 motors on each side of the drivetrain, but the available options either don't provide the reduction you're looking for, or aren't designed for the tried and true West Coast Drive mounting style. After having this problem ourselves, we decided to solve it with the WCP Flipped Gearbox. Add a WCP Bearing Block and you'll be good to go. We made the WCP Flipped Gearbox so that you can make any drivetrain you want.

Accepts 3 CIMs, Mini CIMs, Kraken X60s, or any other 2" bolt circle with a maximum diameter of 2.5" (~64mm)

Bolts, Nuts, and Rivets

Bolts (Product Page)

#10 bots are the best combination of strength, weight, size, and availability in most FRC applications, and for us, it just makes building robots easier. Button Head Cap Screws (BHCS) provide a low-profile hardware solution, while Socket Head Cap Screws (SHCS) provide a stronger, more strip-resistant hex socket with their larger head. The black-oxide coating increases strength and makes the bolts more resistant to corrosion, meaning you’ll never need to replace a bolt due to wear and weather. We also offer #8 bolts to interface with other commonly-used FRC hardware!

Nuts (Product Page)

WCP offers a wide selection of nuts for common size bolts use in FRC. These can be used in various applications, including holding parts together.

Thin Lock Nuts

Locking nuts are used to secure threaded joints and prevent them from loosening under vibration or torque.

Rivet Nut

Rivet Nuts are a great alternative to their traditional counterpart as they allow for parts to be fastened together without having to access both sides.

Heat Set Insert

Heat Set inserts are ideal for 3D printed parts as the installation process allows for the plastic to bind with the insert. This strengthens the plastic immediately, resulting in a secure connection.

Screw to Expand Insert

Screw to Expand inserts are another way to introduce threads into 3D printed parts. The installation process and knurled surface create a secure friction fit.

Tube Connecting Nut

The Tube Connector Nut is an innovative and cost-effective way to create a threaded hole in tubes. It eliminates the need for other more costly methods, such as welding or flow drilling, and can be used to attach a wide range of rods and tubes.

All Tube Connecting Nuts are available in a #10-32 Bore and 1/4"-20 Bore.

Rivets (Product Page)

Rivets are the staples of the engineering world. Align two or more parts with matching holes, place a rivet in the holes, and pop the rivet in the rivet gun to fasten the parts together. To remove an installed rivet, just drill straight through it!

Gear Ratio

Driven Gear / Driving Gear

Gear Basics

Gears can be used to transfer motion from a spinning object to an object you want to rotate (ex: another shaft, a wheel, an arm, etc.). In addition to transferring motion, gears can be used to change the speed and torque inside a mechanism.

Speed and torque are inversely proportional. This means that as one increases, the other must be reduced. For example, if you decrease speed by 3x then torque will increase by 3x.

Changing Speed & Torque

You can change the speed and torque in a gear train by using different sized gears. The size ratio of two meshed gears will determine how much the speed and torque are changed. If two meshed gears are the same size, then speed and torque will remain the same.

Reducing Speed / Increasing Torque

In order to reduce speed and increase torque you must drive a gear with a smaller gear. For example, a 12T gear is driving an 84T gear. Since the 84T gear is 7x larger than the 12T gear driving it, the speed will be reduced by 7x while the torque will be increased by 7x.

Increasing Speed / Reducing Torque

In order to increase speed and reduce torque you must drive a gear with a larger gear. For example, a 48T gear is driving a 24T gear. Since the 24T gear is 2x smaller than the 48T gear driving it, the speed will be increased by 2x while the torque will be reduced by 2x.

Direction Of Rotation

Gears can also be used to change the direction of rotation. Gears spin in the opposite direction of the gear driving it. For example, if you have a gear train with two gears, the direction of rotation will be the opposite of the input. However, if you have three gears in a drivetrain, the direction of rotation at the output will be the same as the input.

When To Use Gears

There are pros and cons to using gears, so it's important to carefully consider your application before electing to use them in your design.

Here are some examples of applications when you should use gears:

The items you need to transfer motion to are close together. Generally speaking, gears are better at transferring motion between items that are close together.
You need a large speed reduction in a small space. Gears allow you to make a large amount of reduction in a relatively small space compared to timing belts and chain.
You need something to spin in opposite directions. Timing belts and chain will always spin in the same direction. So if you need two shafts to spin in opposite directions, gears are one of the easiest ways to do it.

When NOT To Use Gears

You need to transfer motion to something far away. Using a long gear train to transfer motion to something far away usually weighs more than just using timing belts or chain.
High shock loads. Shock loads are extremely high spikes in torque. These can be caused by a number of things like an arm crashing into something. Shock loads can produce spikes in torque many times higher than the mechanism would normally see. since gears transfer motion through a single tooth, they do not handle shock loads as well as timing belts or chain.

Calculating Center-to-Center Distance

CC=\frac{PD_{1}}{2}+\frac{PD_{2}}{2}+Extra

Use this calculator for finding the correct center to center distance for gears (Gear Distance Calculator).

Extra Spacing

Sometimes you want to add extra spacing to center-to-center distance. The benefit of adding extra spacing to a center-to-center distance is to reduce gear wear and help the gearbox run smoother. However, adding extra spacing does increase backlash in the system.

Extra distance to add for center to center:

Exact Spacing: +0.000"
Standard Spacing: +.0015-.003"

In the context of gears, backlash is the amount a shaft can rotate before it drives a mating gear. In some applications, like a roller intake or conveyor, backlash doesn't greatly affect the performance of the the system.

However, in some applications like an arm, backlash can be very detrimental since it makes accurate position control much more difficult. A few degrees of backlash can result in inches of variance at the end of a long arm.

Tooth Spacing

Another way to think about gear spacing is the sum of the teeth in the gear ratio. You can change the gears in any gear ratio, as long as the sum of the two gears remains the same. For example:

Driving Gear

Driven Gear

Sum of Both Gears

Ratio

24T

60T

84T

2.5:1

42T

84T

1:1

12T

72T

84T

6:1

In the table above, you can see some examples of possible gears you can use on a gear ratio with "84 Tooth Spacing". As gear teeth are added or removed from the driving gear, the inverse is added to the driven gear, which keeps the sum at 84T.

20DP Gears

All 20DP WCP gears have a 14.5 degree pressure angle, and have the same 3/8" face width. This means it is easy to change gears in your design to find the perfect gear ratio without having to redesign your gearbox.

The specifications shown in the image below will be standard for all our 20DP Hex Gears.

Addendum Modified Gears

Addendum modifying gears is when you change the tooth profile to reduce undercut, which strengthens the tooth. When gears are addendum modified, it changes its Pitch Diameter, which changes the gear spacing. For example, an addendum modified 11T gear could be on 12T spacing. This means that the gear acts like an 11T gear when doing ratio calculations, but acts like a 12T gear when doing center-to-center calculations.

WCP sells a number of Motor Pinions that are addendum modified. This allows teams to change the tooth count on a motor pinion without having to change the corresponding gear.

Sprockets & Chain

Sprocket & Chain Basics

Common Terms

Pitch is the measurement from one roller chain pin to another. Popular chain sizes used throughout FRC are the #25 and #35, which have their respective pitches of 0.25" and 0.375"

Pitch Diameter also known as PD is the circle that is formed while the chain and sprocket are meshed together and which the chain rotates around. If you wish to find the PD, reference the formula below.

Pitch ÷ sin(180°/Tooth Count)

The Chain Clearance Diameter is the outer diameter of the sprocket while it is meshed with the chain. Knowing this is crucial when placing sprockets in tight places to ensure that no interference is being created. If you wish to find the Clearance Diameter, reference the formula below, along with an example equation for the sprocket shown above.

Pitch Diameter + Pitch

24T - #25 Sprocket

1.915 + 0.250 = 2.165

The Outside Diameter also known as OD refers to the size of the actual sprocket.

Calculating Center to Center

When deciding the placement and spacing of your sprocket and chain it is important to keep in mind that the Center to Center distance can be a fully custom measurement to ensure compatibility in your system, or can be decided through a pre-determined chain length.

The basic rule of thumb when deciding on a custom Center to Center distance is that it should be anywhere from 30-50 times the pitch of the desired chain for optimal usage and should not exceed 80 times the pitch.

Proper Tension

Ensuring that proper tension is present in a sprocket and chain system is crucial for the sake of system integrity and performance. Achieving proper tension is a fairly simple task to do when using a chain breaker tool and tensioner offered through WCP. Such as the Spartan Chain Tensioner or the Chain TurnBuckle.

Adding Chain Tensioner

Implementing our chain tensioners into your system is a an easy task due to them having the necessary clearance holes for the roller pins. Use the chain breaker tool to partially remove the pin from the chain and lay your selected chain tensioner in place, then simply reset the pin back into place.

Idlers

Idlers are yet another way to ensure proper tension is present in a chain and sprocket system as they can be placed either on inside or outside of the chain loop to provide more contact with the sprocket and decrease slack. Adding an idler to the chain loop does not affect the ratio and can actually benefit performance if placed near the driving sprocket as it allows for more meshing.

Bushings (Product Page)

Bushings are lightweight, low-friction components that take the place of ball bearings in low-load, low speed scenarios. While they’re probably not suitable for flywheels, intake rollers, and drivetrains, we believe they’re the perfect fit for pneumatically-actuated joints and some low-load rotary joints, like simple arms and pivoting structures. We like bushings because they are:

Lightweight, which adds up in weight savings when replacing bearings with bushings
Extremely cheap, sometimes only 25% the cost of an equivalent bearing
Toleranced for a clean fit with commonly-used FRC stock

Linear Bearings (Product Page)

These specialty bearings slide axially along a round shaft or tube’s length in order to achieve simple linear motion. Use a set of linear bearings to replace complex radial bearing stack setups and build sliding mechanisms with the strength and rigidity of FRC linear elevators for a fraction of the complexity!

While our linear bearings work with any shaft or tube material, we recommend thin-wall steel in heavy-use subsystems to decrease wear on the shaft while still maintaining strength and keeping weight low. Alternatively, having replacement shafts or tubes prepared for heavy-use subsystems utilizing linear bearings helps alleviate this problem.

Robot Systems

Elevator ()

Elevators can be more effective at lifting objects than arms because they don’t move the object further away from the robot while lifting. The tradeoff in performance comes with complexity, and often this has kept many teams from making elevator systems on their robots. Our collection of elevator products will help your team make a simple, reliable elevator system that will be sure to elevate your level of play:

Energy chain makes wire management on elevator systems a breeze
Our variety of chain tensioning options let you chain-rig your elevator power
Use a friction brake to hold your elevator in place without stalling your motors
Create your elevator frame with aluminum tubes and gussets

Elevator Blocks ()

The new Elevator Bearing Blocks simplify the sliding element of FRC Elevators. Instead of requiring 4 gussets for each corner of each stage of the elevator, the Elevator Bearing Block simplifies all those parts down to one easy to assemble block.

Notable features:

Fewer parts and no plates.
Compatible with 1/2”, 5/8”, and 3/4” OD bearings.
Easy to assemble and maintain.
Elevator stages can be assembled much closer together, wasting less space.

Wire Management

Energy chain is the industry standard for cable management, especially when it comes to moving systems. WCP carries both Semi-Enclosed which is useful for elevators and Bi Directional energy, typically used for turrets.

Semi-Enclosed Energy Chain (15mm x 30mm, 1 meter length)
Semi-Enclosed Energy Chain (15mm x 45mm, 1 meter length)
Bi Directional Energy Chain (.625" ID, 3ft Length)
Bi Directional Energy Chain (1" ID, 3ft Length)

Rigging & Tensioning

Chain Tensioners

WCP offers #25 and #35 chain compatible tensioners, the Spartan style and the TurnBuckle style. Allowing for precise adjustments, preventing any chain slack that can lead to inefficiencies and potential damage.

Spartan #25 Chain Tensioners and Spartan #35 Chain Tensioners are not meant to wrap around sprockets, so use only in situations where chain does not run continuously around sprocket loops.

Pulley & String

Do you need a single pulley? A double? A triple? You can have 1,323 pulleys, or even more, all by stacking a single part! Our new stackable pulleys allow you to have as many (or as little) pulleys as you’d like by stacking a single part over and over and over. The stackable pulleys are designed to fit together seamlessly, and are sized such that the outer diameter of a 1/4” polycord cable on the pulley is either 1.625” or 2” to match with our flex wheel sizes.

Cascade Pulley Block
1.625" Pulley (1/4" Groove, Single)
UHMWPE Rope (.125" x 25'ft, Black)

Ratchet Plate (1/2" Hex)

The Ratchet Plate is designed to replace the traditional 1/2" hex wrench while also giving teams an easy and direct mounting experience with the integrated #10 hardware clearance holes.

Idler Pulley

Idlers are yet another way to ensure proper tension is present in a system as they can be placed either on inside or outside of the belt loop to provide more contact with the sprocket and decrease slack. Adding an idler to the loop does not affect the ratio and can actually benefit performance if placed near the driving pulley as it allows for more meshing.

Kevlar Belt

Kevlar timing belts are a lightweight and durable material known for its increased durability, improved performance, and reduced maintenance. This makes them ideal for use in timing the operation of moving parts, such as elevators.

Braking System

The Friction Brake allows you to aid your PID controller in holding an arm, elevator or another subsystem in place or even completely hold your mechanism in place without any motor power!

Easy integration with your design
1.875" and 2" bolt pattern compatibility

Accessories

Kraken X60 Powered by TalonFX PowerPole Adapter Board

The Kraken X60 Powered by TalonFX PowerPole Adapter Board was designed in a collaboration between WCP and Vivid-Hosting. The connector board allows teams to easily connectorize the power and CAN screw terminals on the back of the Talon FX. This helps simplify wiring and facilitates faster motor swaps.

In addition, one of the connectors outputs power and CAN, allowing you to power a CAN based sensor like a CANcoder.

Pinions

Motor Pinions are smaller gears that are design to fit on a motor shaft. These gears use a wider 3/4" face width to help strengthen the gear tooth.

Center Distance

Some pinions are designed with a profile shift. This profile shift does two things:

Removes undercut on the tooth, making it stronger and easier to manufacture.
Increases the center distance of the pinion.

You must account for the increase in center distance when using these pinions. For example, a 10T gear on 12T center distance, will act like a 10T gear when you're doing ratio calculations but act like a 12T gear when you're doing center distance calculations.

Another way to think about it is if you have a 12T (on 12T spacing) gear driving a 60T gear, it can be replaced with a 10T (on 12T spacing) without having to change the center distance. With the 12T (on 12T spacing) gear, the ratio was 5:1 (60/12). With a 10T (on 12T spacing) gear, the ratio is 6:1 (60/10)

SplineXL Tubing (Product Page)

The SplineXL Tubing can be used in a variety of applications, including feeder or intake systems.

Our spline profile was inspired by the farming industry which has been using spline tubes on PTO applications. The profile allows for some neat stuff:

Easy to machine profiles
Simple and lightweight interior dead axle assemblies
Torque transfer available via star profile

Plastics (Product Page)

Polycarbonate is a great solution for making simple brackets and sponsor panels. These 0.5mm and 1.5mm thick sheets of smoked polycarbonate will come in 3’ x 6’ sheets. The 1.5mm thick sheets are great for thinner brackets and the 0.5mm thick sheets are great for sponsor panels and can even be cut with a pair of scissors.
