Problems solved by technology

Due to the lack of domestic research on harmonic reducers, especially the single test for flexible bearings or flexible wheels, the understanding of their failure mechanisms and diagnostic methods is insufficient, which in turn affects the life calculation and design of harmonic reducers. Therefore, It is of great significance to conduct experimental research on flexible bearings and flexible wheels

Abstract

The invention relates to a performance test device for double flexible components of an internal force dissipative torque balanced harmonic drive. A servo loading system is fixed on the driving systemthrough bolt connection, and a heat dissipation system is a part of the servo loading system. The driving system is connected with the servo loading system and the tested parts --- a flexible wheel and a flexible bearing --- to drive separately; the servo loading system balances the external torque load by the friction moment generated by a friction bearing, applies tangential load on the flexible wheel by the elastic loading gear, and converts its work into frictional heat and dissipates it by the wind-cooling generated by the heat dissipation system; the heat dissipation system is part of the structure of the servo loading system, to meet the ventilation and heat dissipation problems in the test process; the support system is the support of the driving system, the servo loading system and the data acquisition and processing system; the performance of flexible bearings can be tested during the test, the performance of flexible wheels can be tested, and the performance of the integrated components of flexible bearings and flexible wheels can also be tested.
