Analysis and experimental study on vibration characteristics of the RV reducer

RV reducers are commonly employed in precision transmissions, such as robot joints, owing to their multi-tooth contact characteristics, strong impact resistance, and low backlash. A finite element modal analysis of the reducer was conducted this study reduce influence vibration on transmission performance improve its characteristics. The characteristics analyzed according principles. Combined with theoretical basis analysis, method used analyze main components, natural frequencies modes each component were obtained. input shaft cycloidal gear performed, patterns reducer, well gear, comprehensively. distribution order frequency deformation components can be determined by analyzing array components. An test platform established verify accuracy simulation. Vibration signals under three different working conditions collected, simulation verified signal, which provided important guidance for design optimization subsequent reducer.
