Research on test system and technology of wide-range gear transmission characteristics

In order to realize the wide range transmission characteristic test of a set of gears at the same time, this paper proposes a wide range gear working characteristic test system. The test system can be used to test various gears of different specifications and types under quasi-static and dynamic conditions. In this paper, the test object, working range, test item, working principle, structure composition, driving loading principle and control testing principle of the test system are described; for the test piece, the finite element model of gear transmission system suitable for quasi-static loading tooth contact analysis is established and the loading contact analysis is carried out; the test bench for testing item verification is developed, and the tooth contact area is introduced Test principle of detection and transmission error detection; on the basis of verification test-bed, the tooth contact area and gear transmission error detection are carried out, and the test results are compared with the simulation results, and the analysis results show that the two are consistent. The test system developed in this paper can obtain the parameters of gear transmission in the whole work field. which will provide comprehensive test basis for gear design, manufacturing and assembly.
