Belts and Pulleys Basics

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:

1. Belt pitch to be used

   1. 3mm for GT2/GT3 belts

   2. 5mm for HTD Belts

2. Number of teeth for both pulleys

3. 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.

GT2 Pulleys

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.

The Robonauts' Everybot is an affordable, competitive, and elegant robot intended to play the FIRST Robotics Competition challenge. Everybot can be built with nothing but basic tools and items found in either the kit of parts or purchased from your local hardware store or online FRC retailers. The dimensions in this year's Everybot document are nominal dimensions, unless otherwise noted.

WCP offers the essential components that teams would need during the FRC Build Season. With components ranging from CNC machining and 3D Printers to help teams rapidly iterate designs, to all the hardware needed to watch your designs become a reality.

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!

Shoulder Bolts

#8-32 Bolts

#10-32 Bolts

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.

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!

Our rivets come in:

• 5/32" and 3/16" diameters

• Grip lengths from 1/32" to 1/2"

• Regular and High Strength models

5/32" Blind Rivets

3/16" Blind Rivets

*This option is only available in the High Strength Version

Sizes offered for 1/2" and 3/8" Hex:

• 1/32", 1/16", 1/8", 1/4", 1/2", 1", 2"

Metal Washers (Product Page)

Metal washers used to space out #10 bolts, 1/4"-20 bolts, and even 1-1/8" OD Bearings.

Steel Flat Washers

Battery Locking Washers (Product Page)

These washers use a wedge-locking mechanism to secure bolts with tension, preventing them from loosening unintentionally. When the bolt is tightened, the cams on the washers engage with each other and create a wedge-effect, which prevents the bolt from rotating.

WCP Rotation SS Gearbox (Product Page | )

A 2 stage gearbox designed around the new friction brake. This gearbox is perfect for arms or turrets and many other situations where an axis needs to rotate.

• Ideal for arms and other low revolution speed mechanisms

• Easy integration with Friction Brake

• Ability to get more reduction by mounting a VersaPlanetary Gearbox

• Fixed or adjustable mounting options

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.

Shaft Stock (Product Page)

WCP offers several different lightweight shaft stock options made from both 6061 aluminum (for tube axles) and 7075 T6 Aluminum (for high-strength hex shafts handling torsional loads). These shaft lengths are correctly toleranced such that they fit perfectly through bearings and hubs, without extra work.

Spacers and Standoffs

Aluminum Spacers (Product Page)

Our aluminum spacers are offered in a wide variety of lengths in order to speed up your spacer-making process, or even remove the manufacturing step altogether!

Sprocket & Chain Basics

Common Terms

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.

Basic Terms

Basic Equations

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.

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

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"

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:

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.

• Includes gear and mounting hardware

• 14.5° pressure angle

• Mounts to various sized FRC motors

• Mounts to other motors or gearboxes with similar shaft sizes

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.

The table above demonstrates how you can use addendum modified motor pinions to change gear ratios without having to change the Driven Gear.

Hex Bore Pocketed Gears (Steel | Aluminum)

WCP sells pocketed versions of steel and aluminum gears for maximum weight savings. On average each pocketed gear is 50% lighter than the unpocketed version!
