This 3 stage gearbox is designed to assist teams in creating rotational arm joints. Making this gearbox is perfect for arms or turrets and many other situations where an axis needs to rotate.

Notable Features

• 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

• Ability to add a 3rd stage via VersaPlanetary (Can be 1 or more stages)

• Ability to add a 4th stage via Chain Reduction

• Friction Brake Integration

• CAM Tensioning

Step 1

Press both bearings into the motor plate. This should be a light press it. The bearing flanges should both be on the same side.

Step 2

Install the Kraken motor with two #10-32 x 1/2”L bolts.

Install the desired pinion and 1/16” Kraken Spacer.

Step 3

Slide all desired gears and shaft into place.

Step 4

Press bearings into the motor plate. This should be a light press fit. The bearing flanges should be on the same side.

This example utilizes the WCP Rotation SS Gearbox and Versa Blocks for a simple and easy to fabricate arm that teams with limited manufacturing resources can make with basic hand tools.

Mounting Holes

These are some tips and tricks to keep the product running without a hitch. Failure to do maintenance may result in issues.

First Time Assembly

1. Use Vibra-Tite VC-3 threadlocker on all bolts

2. Grease all gears

   1. We recommend Lucas Red "N" Tacky for all gears

3. All bolts are tight and there are no gaps in the assembly

4. Gears mesh correctly and everything spins smoothly

General Maintenance

1. Check for excessive wear in gears

2. Reapply grease

3. Verify everything still spins smoothly

4. No damage to plastic encoder parts or belts

Yearly Maintenance

1. Disassemble gearbox

2. Replace any worn gears

3. Clean all components

4. Inspect all components for wear or damage

5. Reassemble with new bolts with Vibra-Tite VC-3 and grease all gears

WCP Rotation SS Gearbox Assembly Instructions

The following pages cover the basic assembly instructions for the Rotation Gearbox

Step 5

The brake must be assembled in place. For more detailed brake assembly steps, refer to the

Step 6

Attach the two halves of the gearbox using four #10-32 x 1.75”L bolts and four 1.125”L spacers.

Step 7

Attached desired output sprocket and retain with 1/2” Snap Ring.

Step 8

Use two #10-32 x 1/2”L bolts to attach the Mag Encoder mount.

Step 9

The gearbox spacer is required for the proper spacing to mount to a 1”x2” tube. Align the spacer plate with the gearbox plate and use the mounting holes.

Step 10

Apply Lucas Red "N" Tacky grease to all gears after final assembly to ensure smooth operation and reduce wear during use. Once greased, rotate and spin the wheel to distribute the grease evenly before powering up.

After running gearbox for 15-30 minutes, reapply a light amount of grease. Reapply as needed.
