Study of contact load on cycloid wheel of RV reducer based on MATLAB

This paper analyses the working principle of RV reducer and the actual tooth profile equation of cycloid wheel, and deduces the distribution law of contact load on cycloid wheel in transient state by considering the initial meshing gap between pin teeth and cycloid wheel and the contact deformation generated during meshing. Taking an RV reducer as the research object, the contact load of the cycloid wheel is calculated by using MATLAB programming, and the change curve of contact load and crank shaft rotation angle is obtained, which provides theoretical support for the analysis and design of RV reducer.
