Optimal Design and Characteristic Analysis of a Special Type Gear Test Rig

In this article, the rationality to determine the mechanical design of the test rig for the beveloid gear with intersecting axes has been verified, and the overall performance of the test rig has been predicted. First, the three-dimensional solid models of all components have been established, and the virtual prototype simulation technology has been used for its kinematics simulation. Then, the static and dynamic performance of the key components has been analyzed. At last, the transfer matrix method has been used to analyze the torsional vibration mechanics of the closed gear test rig, so as to obtain the simulation curves of dynamic load factors of the test gear under different speeds. The results show that the whole test rig can be applied in the gear test with intersecting axes, without the auxiliary test gear pair, which has good gearing test accuracy. Besides, the test rig itself has low costs and good running economy.
