Problems solved by technology

[0003] There is no design for the extreme environmental conditions of high and low temperature ±100°C in the existing torque rotation stiffness test. Therefore, in order to meet the performance test requirements of complex precision mechanisms in extreme space environments, a torque rotation stiffness that can be realized in extreme environments is developed. Performance testing is of great significance to the development of space agency ground testing technology

Abstract

A high and low temperature test device for torque rotation stiffness, which includes a basic platform, an integrated drive and test module, an overload protection module, an adjustment module and a support module, the overload protection module is a magnetic powder brake overload protection module; the overload protection module, the support module, The high and low temperature box and the adjustment module are installed on the basic platform, the high and low temperature box is located between the two support modules, the drive and measurement integration module is installed on the adjustment module, and the transmission shaft between the torsion drive module and the support module is equipped with a dynamic torque The sensor, the angle encoder, the torsion drive module and the output shaft connected to the output of the overload protection module are respectively supported and rotated by the support module. An annular elastic gasket is installed on the side wall of the high and low temperature box, and the annular elastic gasket is located in the casing. The air seal ring on the box shaft is in the groove and is in frictional contact with the bottom surface of the groove. The air seal ring is a circular ring formed by butting two metal half rings. The invention is suitable for high and low temperature tests, and the test is flexible and convenient.

Description

technical field [0001] The invention relates to a stiffness testing device, in particular to a torque rotation stiffness high and low temperature testing device. Background technique [0002] During the development and implementation of major aerospace engineering fields such as space station construction, lunar exploration projects, and Mars exploration, a large number of sophisticated and complex mechanisms and components need to simulate extreme environments such as space vacuum, high and low temperature on the ground, and perform performance tests on the tested parts and reliability assessment. [0003] There is no design for the extreme environmental conditions of high and low temperature ±100°C in the existing torque rotation stiffness test. Therefore, in order to meet the performance test requirements of complex precision mechanisms in extreme space environments, a torque rotation stiffness that can be realized in extreme environments is developed. Performance testin...
