Abstract

A torque testing device under a thermal vacuum environment includes an adjusting machine base, an observation group, a driving lever device, connecting splines and a thermal vacuum box, wherein the adjusting machine base and the driving lever device are mounted in the thermal vacuum box; a workpiece to be tested is mounted on the adjusting machine base; an output shaft of the workpiece to be tested is connected with a magnetofluid seal transmission shaft through the connecting splines and is led out of the thermal vacuum box; the connecting splines are connected with the driving lever device; the observation group is arranged on the box wall of the thermal vacuum box. The device adopts observation lenses to observe and record the position of the output shaft of the workpiece to be tested, adopts the driving lever device to control the disconnection and connection of the output shaft of the workpiece to be tested and the magnetofluid seal transmission shaft, adopts the adjusting machine base to adjust the spatial position of the workpiece to be tested in the thermal vacuum box, effectively avoids the influence of deformation of the workpiece to be tested on the testing in a thermal vacuum testing, is suitable for high-precision torque testing under the thermal vacuum environment, and the like, and is simple to operate and high in precision.

Description

technical field [0001] The invention relates to a torque testing device in a thermal vacuum environment Background technique [0002] Aerospace equipment has extremely high performance requirements due to the particularity of its application in the outer space environment. In order to meet the design requirements, it is necessary to simulate the thermal vacuum environment of outer space on the ground, and test the performance and function of the DUT under vacuum and thermal cycle conditions. For example, in the thermal vacuum test that drives or loads the tested part to simulate the drive and load of the tested mechanism, not only a reasonable transmission device is required, but also real-time high-precision measurement equipment such as torque, rotation angle and rotational speed. Ability. [0003] Due to the reduced reliability of sensors and power equipment in a thermal vacuum environment, the service life is shortened, and it is difficult to control during the test pr...
