Abstract

Abstract: Using a high-accuracy optical torque transducer, a starting torque test system for harmonic drive is developed based on servo loading. The test range of the system is 0~0.07 N·m and accuracy is better than ±1.0×10^-3 N·m. A servo motor is controlled in current mode with output torque increasing slowly, to apply driving torque on the measured object. A high-precision torque transducer, which is placed between the servo motor and the object, is used to acquire the driving torque exerted on the measured object. When the object begins to rotate continuously, the driving torque applied on the object is regarded as the staring torque. The detailed design, analysis of accuracy and experimental verification are conducted for the torque test system. Experimental results show that the test system can realize measurement automation of starting torque for harmonic drive with high testing accuracy.

Key words: instrument and meter technique, test system, harmonic drive, servo loading, starting torque
