VersaPlanetary Gearbox

The VersaPlanetary is a battle-tested modular planetary gearbox system designed specifically for use in the FIRST ® Robotics market. Designers choose one of four output shafts, configure a single-stage planetary using one of six different reductions, or build a multi-stage gearbox using any of the different ratio combinations.

All of the VersaPlanetary gearboxes include mounting plates & hardware for typical FIRST ®Robotics Competition motors (550, 775 Series, 9015 size motors, and the VEXpro BAG motor) -- these plates are custom designed for each motor to provide perfect piloting and high efficiency.

What good is a versatile system if it’s not easy to take apart and re-configure? That’s why we released the VersaPlanetary V2 with assembly screws in the back of the gearbox. This makes it easy to change gear ratios, encoders, motors, etc. without have to take apart your entire mechanism. Another feature of the VersaPlanetary that makes it easy to use is the removable shaft coupler system. This system allows you to change motors without the need to buy a special pinion and press it on. In addition, the VersaPlanetary uses the same pilot and bolt circle as the CIM, allowing you to run a VersaPlanetary anywhere a CIM motor mounts.

The VersaPlanetary has a variety of options for mounting. Each gearbox has four 10-32 threaded holes on top and bottom of its housing for easy side mounting. In addition, there are also holes on the front which allow face-mounting. Conveniently, these holes are on a 2" bolt circle; this is the same as the CIM motor - anywhere you can mount a CIM-style motor, you can mount a VersaPlanetary.

Other features include:
 

  • Six different planetary gear stages can be used to create up to 72 unique gear ratios, the most of any COTS gearbox in FRC or FTC.
  • Adapts to a variety of FRC motors (BAG, Mini CIM, RS-550, RS-775, 775pro, Redline, AM-9015, and CIM)
  • Adapts to a variety of FTC motors (AndyMark NeveRest, REV HD Hex Motor, Tetrix TorqueNADO)
  • ABEC-1/ISO 492 Class Normal Bearings, rated for 20,000+ RPM
  • AGMA-11 quality planet and sun gears made from hardened 4140 steel
