A Measuring Method of Working Performance of Wave Generator

Abstract

The invention relates to a method for measuring and evaluating the working performance of a wave generator. The method comprises the steps of 1, calculating an angle parameter alpha of a meshing areaand the number 4N-2 of gear tooth pairs participating in meshing; 2, taking basic parameters of a rigid gear as detection parameters of a flexible gear, and taking the designed tooth shape of the rigid gear as the theoretical tooth shape of the flexible gear; 3, carrying out measuring to obtain an actual double-side tooth shape coordinate point of the previous gear tooth of the flexible gear in acurrent state; 4, rotating the wave generator for an angle delta relative to the flexible gear, and carrying out measuring to obtain a double-side tooth shape coordinate point of the gear tooth in thecurrent state according to a common gear detection method; 5, carrying out rotating for the same angle delta every time, and measuring double-side tooth shape coordinate points of the same gear toothof the flexible gear in different working states; and 6, analyzing the change influence of the shape of the wave generator on performance indexes of the flexible gear. The core of the method is thatthe change of the actual tooth shape by the wave generator is embodied, and the problem that the working performance of the wave generator cannot be really reflected due to a gap between an existing simulation technology and an actual use condition is solved.
