Abstract

The invention is a torque spring loader for space harmony gear decelerator experiment desk, which includes driving engine and experiment harmony gear decelerator connected to the output end of the driving engine, it also includes driving engine and torque spring connected to the driving engine through harmony gear decelerator, the output end of the experiment harmony gear decelerator is connected to the output end of the torque spring through synchronous wheel group. Through the angle difference between the decelerator and the harmony gear output axis, thus the torque spring rotates with the two axes slowly, it is deformed by the angle difference, and it supplies load to the experiment decelerator by generating torque difference between the two harmony gear decelerators.

Description

technical field [0001] The invention belongs to a mechanical synchronous loading device, in particular to a torque spring loader for a space harmonic gear reducer test bench. Background technique [0002] In order to test the various performances of the harmonic gear reducer used in the space environment to drive the sunshield on the artificial satellite, the solar cell, and the antenna to rotate slowly, people have built a space harmonic gear reducer test bench. This test bench needs to be able to operate in the atmosphere, vacuum and thermal vacuum environment, and its operating temperature range is -80°C-75°C. In order to simulate the slow rotation of the satellite visor, battery, and antenna in the laboratory, the test bench needs to be loaded at a low speed. At present, commonly used load and absorbing equipment at home and abroad include electric synchronous loader, magnetic powder brake, hysteresis dynamometer, eddy current dynamometer, hydraulic dynamometer, hydraul...
