Problems solved by technology

[0003] There is no design for the extreme environmental conditions of high and low temperature ±100°C in the existing transmission efficiency test. Therefore, in order to meet the performance test requirements of complex precision mechanisms in extreme space environments, a performance test in extreme environments is developed. For space The development of institutional ground testing technology is of great significance

Abstract

A high and low temperature test device for transmission efficiency, which includes a basic platform, a rotary drive module, a loading module, an adjustment module, a support module and a measurement module; a rotary drive module and a support module are installed on one adjustment module, and the output terminal of the rotary drive module is connected The box-through shaft is supported and rotated by the support module, and the loading module and the support module are installed on the other adjustment module. The box-through shaft connected to the output end of the loading module is supported and rotated by the support module. There is a measurement module, and an annular elastic gasket is installed on the side wall of the high and low temperature box. The two shafts passing through the box pass through the annular elastic gasket on the high and low temperature box and are supported by the tooling in the high and low temperature box. The annular elastic seal The pad is located in the groove of the air seal ring sleeved on the shaft through the box and is in frictional contact with the bottom surface of the groove. The invention can be used to verify the feasibility and efficiency of the tested part in the high and low temperature environment, and the device test is flexible and convenient.

Description

technical field [0001] The invention relates to a test device, in particular to a high and low temperature test device for transmission efficiency. Background technique [0002] In the development and implementation of major aerospace engineering fields such as space station construction, lunar exploration projects, and Mars exploration, there are a large number of sophisticated and complex mechanisms and components that need to be simulated on the ground in extreme environments such as space vacuum, high and low temperature, etc. Performance testing and reliability assessment. [0003] There is no design for the extreme environmental conditions of high and low temperature ±100°C in the existing transmission efficiency test. Therefore, in order to meet the performance test requirements of complex precision mechanisms in extreme space environments, a performance test in extreme environments is developed. For space The development of institutional ground testing techniques is...
