Shaft end type torque loader

Abstract

The invention aims to provides a shaft end type torque loader, which comprises a collecting ring, a reducer, an input shaft, an output shaft, a drive motor, a base, a bearing bracket arranged outside the input shaft, an output shaft sleeve arranged outside the output shaft, an output shaft end bearing bracket arranged outside the output shaft sleeve, a harmonic reducer shell fixed outside a harmonic reducer and a planetary gear train reducer shell fixed outside a planetary gear train reducer. The collecting ring is sleeved on the input shaft. The input shaft is connected with the drive motor. One end of the harmonic reducer is connected with the drive motor, while the other end thereof is connected with the planetary gear train reducer. The planetary gear train reducer is also connected with the output shaft. Both the bearing bracket and the output shaft end bearing bracket are fixed on the base. The shaft end type torque loader can change the size and the direction of a torque at the closed end, can stably maintain a torque value at the closed end, and has an unlimited travel angle of the loading motion, capability of amplifying physical factors as well as small energy consumption and low vibration and noise in the operating process.

Description

technical field [0001] The present invention relates to a mechanical device for torque loading. Background technique [0002] In the research and development process of the reducer for large mechanical equipment, its performance is often tested through a closed test system. In the closed test system, a loader is used to apply load to the entire test system to simulate the actual working state of the reducer. The load is reflected in the form of power, a large torque is applied by the loader, and the entire test system is equipped with a high speed, so that a large power can be applied to the test system. For the test system, the form of coaxial transmission is adopted. Considering the stable operation and small footprint, the shaft end loading method is often used, that is, the shaft end loader. If the torque range that the loader can apply is large and the loading torque is stable, then the performance of the test system will be excellent and the application range will be ...
