Research on Test System of Comprehensive Transmission Performance of Wide-range Gears

Abstract

According to the requirement of research on transmission performance of gear pair in chassis of a heavy-duty vehicle, this paper develops a comprehensive testing system suitable for wide-range gear pairs, which can realize various types of performance testing of parallel and spiral bevel gears under quasi-static and dynamic conditions. Then taking a hypoid gear for example, The finite element model of hypoid gear transmission system suitable for quasi-static tooth contact analysis is established. Through the contact analysis, the simulation results of tooth surface contact area, root bending stress and transmission error are obtained, which are in good agreement with the test results.
