Abstract

The mechanical calculation model of rotary-vertical (RV) reducer is established on the basis of considering displacement and stiffness. Without considering the manufacturing error, the parameters of the RV reducer are input into the model and solved by MATLAB calculation software. Comparing the solution results with the analysis results based on Hertz contact theory, the error is within a reasonable range, which verifies the reliability of the mechanical calculation model. The manufacturing errors of the RV reducer based on the high-precision measuring instrument were imported into the mechanical calculation model for solving, the results of the force analysis of the tooth surface of the cycloidal pinwheel considering the manufacturing errors were obtained. The maximum value of the load was 1713N, and the number of meshing teeth was 17 pairs. Compared with the case without manufacturing error, the maximum value of load increased by 89% and the number of meshed teeth decreased by two pairs. Based on the existing experimental data, the force on the tooth surface of the cycloid pinwheel after considering the manufacturing error is closer to the actual situation.
