Abstract

The invention relates to a harmonic gear reducer starting torque and friction resistance torque testing system. The harmonic gear reducer starting torque and friction resistance torque testing system includes a loading driving module, a torque and rotation angle measurement module, a control and data processing module and a testing bench. In a starting torque test, the control and data processing module performs starting torque testing according to a rotation angle test mode or a rotation speed test mode, and finds the maximum value of a loaded torque according to torque values in a testing process, and adopts the maximum value of the loaded torque as the starting torque of a test point of a tested harmonic gear reducer (11). In a friction resistance torque test, the control and data processing module performs friction resistance torque testing according to a friction resistance torque test mode, and acquires the minimum value, maximum value and average value of a friction resistance torque in a testing process according to acquired torque values, rotation angle values and time in the testing process. With the harmonic gear reducer starting torque and friction resistance torque testing system of the invention adopted, problems in accurate, fast and automated measurement of starting torques and friction resistance torques of harmonic gear reducers can be solved, and measurement accuracy can be improved.

Description

technical field [0001] The invention relates to a testing system and testing method for the starting torque and friction resistance torque of a harmonic gear reducer. Background technique [0002] Harmonic gear reducer is a kind of reducer developed by using the principle of planetary gear transmission. Harmonic gear transmission has shown its superiority since its appearance, with high transmission ratio, small backlash, high transmission precision and few parts , Easy installation, small size, light weight, high torque capacity, high efficiency, stable transmission, low noise, and can transmit motion to confined spaces. Therefore, harmonic gear reducers are increasingly widely used in aerospace, bionic machinery, precision machinery, robots and other fields. [0003] After the precision harmonic gear reducer is processed and assembled, it is necessary to measure the starting torque and friction resistance torque to verify and evaluate the overall performance and assembly ...
