Contact analysis of cycloidal pin wheel drive based on modification

The primary focus of this research is the investigation of the cycloidal pin wheel drive system, specifically emphasizing the derivation of the tooth profile equation for the cycloidal wheel. By applying Hertzian contact theory, the spacing between two wheels during initial interlocking, along with the contemplation of contact distortion throughout the meshing procedure, are taken into account. This enables accurate determination of the interlocking position and derivation of the contact load and stress during meshing. Using the prototype as the analysis object, MATLAB was utilized for iterative calculations, yielding the curve of contact load and stress relative to the meshing phase angle. It provides theoretical support and experimental data for the analysis and optimization of cycloidal pin wheel drive, and enhances understanding of the drive system's mechanism and performance.
