摘要

Abstract

To overcome the design limitations of traditional harmonic reducers

which are predominantly based on involute tooth profiles

this paper investigates the full-process design and simulation of a novel harmonic reducer utilizing a cycloidal pinwheel. Taking rated output torque and transmission ratio as core metrics

the design parameters for the reducer's flexible gear

rigid gear

and wave generator are determined. Three-dimensional modeling of the flexible gear

rigid gear

and wave generator was completed using SolidWorks software. The cycloidal tooth profile was generated via "Equation-Driven Curve

" followed by assembly constraints to complete the overall assembly. A simulation model was constructed using RecurDyn

employing the Step-IF function to achieve smooth startup and delayed loading. Simulation results indicate: steady-state output speed values closely match theoretical predictions

transmission ratio deviation is negligible

and maximum contact forces meet strength requirements

validating the model's feasibility. This design fills the gap in harmonic drives utilizing cycloidal tooth profiles

providing a theoretical framework and technical pathway for similar reducer designs.
