Electric motors and gear reducers play a critical role in robotics and mobility applications, providing the precise control, appropriate rotational speed, and torque required for each field. High-reduction gear reducers can enhance motor output while minimizing package size, making them ideal for vehicle steering systems by effectively countering external forces from the ground with appropriate backdriveability. In this study, a Wolfrom Planetary Gear Train (PGT) was selected for its ability to achieve both a compact package and high reduction ratio. To improve assembly, the design was optimized so that all compound planetary gears could be assembled in the same phase. The distribution and characteristics of the resulting design combinations were analyzed, and a Compactness Factor (CF) was defined to rank these combinations. Considering mass production, the optimal design combination was selected based on the target reduction ratio and the size of the motor shaft to be applied. A prototype of the gear reducer was then manufactured using off-the-shelf gears and 3D printing technology, followed by assembly and operational tests to validate its functionality. As a result, a small gear reducer prototype with a 207.5:1 reduction ratio, measuring 92 mm in diameter and 32 mm in thickness, was successfully developed. |
