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.


  • 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

Description

Details

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
 

VersaPlanetary v1 vs VersaPlanetary v2

The VersaPlanetary v2 assembly is now held together with screws that install on the "back" (motor side) of the housing. This means that the gearbox can be disassembled to change gearsets without removing the gearbox output from the robot. Bosses have been added to the sides of the gearbox so when it is side-mounted you can "crank down" on the mounting screws without accidentally misaligning a ring-gear stage. The v1 & v2 input and output blocks cannot be mixed and matched - A v2 input block must be used with a v2 output block. Ring gears and gear kits are compatible between v1 & v2


 

The base VersaPlanetary kits now include an optional pilot ring that will allow users to pilot the VersaPlanetary on a 0.75" hole, instead of relying on screw clearances to locate the gearbox. The plastic motor mounting plates now pilot on the input block.

Weight
Default Weight
  • Base VersaPlanetary Kit (with Output Shaft) - 0.36 lb
  • Gear Kits with Ring Gear - 0.2 lb each

The theoretical weight for your VersaPlanetary can be calculated as follows:
Base Kit + (Number of Stages × Weight of a Stage)

Example VersaPlanetary Weights:
  • Single Stage: 0.36 lb + 0.2lb = 0.56 lb
  • Two Stage: 0.36 lb + (2 × 0.2 lb) = 0.76 lb
