WCP PlanetaryX

The PlanetaryX is a modular planetary gearbox designed for FRC robotics and compact mechanisms. Individual gear stages can be stacked to create the reduction you need, and the configuration can be changed later without replacing the entire gearbox.

The PlanetaryX Base Kit includes: the Input Block, Output Block, SplineXS Input Coupler, 6x 3mm dowel pins, and hardware for a 1-3 stage assembly. A ratio kit is required to complete the gearbox.

 Available 3:1, 4:1, and 5:1 gear sets can be combined to create the desired overall reduction.

PlanetaryX supports direct mounting to SplineXS-compatible motors or can be configured with alternate input options for other motors. Its compact design and flexible mounting options make it suitable for a wide range of FRC mechanisms.

Features

• Modular Multi-Stage Design
• Compact 2" x 2.5" x 0.75" Stage Footprint
• Integrated Motor Bolt Circles and Bearing Bores
• Direct Motor Mounting or 1/2" Hex Input
• #10-32 Tapped Mounting Holes on All Four Sides
• Compatible with Standard 1/2" Pitch Spacing
• Features four standard FRC motor bolt circle patterns, providing compatibility with most legal FRC motors. The input interface features bolt circles compatible with Kraken X60, Kraken X44, and Minion.
• Support both Direct Motor input and 1/2" Hex Shaft Input 
• Mountable from either end
• Dual-carrier planetary stage design
• Standard 1/2" hex output
• Six 3mm dowel pins for additional output torque capacity
• Integrated mounting pattern for WCP ThroughBore Encoder
• Individual stages can be added or removed as needed

Kit Includes:

Build the Ratio You Need

PlanetaryX uses individual 0.75" wide gear stages that stack between the Input and Output Blocks.

Available gear sets:

• 3:1 PlanetaryX Gear Set
• 4:1 PlanetaryX Gear Set
• 5:1 PlanetaryX Gear Set

Multiple stages can be combined to create the overall reduction required for your mechanism. For example, three 5:1 stages provide a 125:1 overall reduction.

Input Options

The Base Kit includes a SplineXS Input Coupler for direct connection to compatible motors. Additional input options are available for other motor and shaft configurations, including:

• 8mm keyed input
• 1/2" male hex input
• 1/2" female hex input

Output and Mounting

The Output Block uses a standard 1/2" hex socket. Six 3mm holes on a 0.75" bolt circle accept the included dowel pins. This optional interface provides additional resistance to rotational shear and increases output torque capacity.

The Input and Output Blocks provide multiple #10-32 mounting options and are designed around the 1/2" Pitch Spacing Standard. The gearbox can be mounted from either end.

Specifications

Note: The PlanetaryX Base Kit requires at least one ratio kit to create a complete gearbox.
