Contact analysis of spiral bevel gear transmission with errors
Author:
Based on the theory of multi-body system error modeling and the principle of gear meshing, a method for error tooth contact analysis (ETCA) of spiral bevel gears is proposed, which includes geometric errors of machine tool motion and installation errors of gear pairs. Taking the arc tooth spiral bevel gear processed by the SGM method (large wheel generating method and small wheel deformation method) as an example, the ETCA analysis is conducted to obtain the quantitative relationship between machine tool motion errors, installation errors, and the machining quality of spiral bevel gear tooth surfaces. A comparative analysis of the results of ETCA and TCA shows that machine tool motion errors and installation errors have a significant impact on the tooth surface contact quality of spiral bevel gears. To achieve more accurate reverse adjustment of machining parameters through tooth surface contact analysis, the analysis results of ETCA are used to guide the reverse adjustment of machining parameters more reasonably.
