Contains the design, documentation, and implementation details for an additional gearbox compatible with the CyberGear motor. It enhances the CyberGear motor's functionality with extra reduction capabilities, making it suitable for applications requiring higher torque.
Detailed operational instructions, assembly procedures, and simple torque tests are available in our YouTube video linked below. This video also provides practical insights into the assembly and testing processes.
- Internal Gear Teeth: 60
- Sun Gear Teeth: 24
- Planet Gear Teeth: 18
- Reduction Ratio: 1:3.5
The experimental torque is confirmed up to 35Nm, though calculations suggest that the gearbox could theoretically output up to 42Nm, compared to the CyberGear's rated maximum torque of 12Nm.
Parts required to be 3D printed are stored in the 3d_models folder. Notably, the file PlanetGear.stl needs to be printed six times.
The following parts must be purchased for assembly:
- CyberGear Main Unit: x1
- Bearings (6810ZZ): x1
- Bearings (HK0612): x6
- Cylindrical Pin (M6, 20mm): x6
- Thrust Bearing (AXK3552+2AS): x1
- Insert Nut (M4x8x6.4mm): x6
- Screws (M3x45mm): x9
- Screws (M3x15mm): x3
- Screws (M4x10mm): x3
