Problems solved by technology

[0005] 1) The presence of grease leads to contamination of aerospace products in the tank;
[0006] 2) There are many links in the general gear transmission mechanism, which is too dependent on lubrication, and the deformation at low temperature can easily lead to its failure and jamming;

Abstract

The invention discloses a heavy-load low-speed spinning motion simulator for vacuum low temperature. The heavy-load low-speed spinning motion simulator comprises a substrate, an operating platform assembly, a primary transmission mechanism, a spindle, a thrust bearing, a secondary transmission mechanism, a roller mechanism and an adjusting seat. Simple two-stage transmission mechanisms with large transmission ratio are designed in the motion simulator, the output torque of the motion simulator can be effectively increased, the low-speed requirement of tests can be met, the simple transmission structure facilitates the implementation of solid lubrication, all structural members have enough strong rigidity, the transmission ratio of the transmission mechanisms is large, lubricators used in vacuum low temperature conditions are adopted, and the main mating surface of the transmission mechanisms can adapt to the condensed deformation.

Description

technical field [0001] The invention relates to a motion simulator, in particular to a heavy-load low-speed spin motion simulator used in vacuum and low temperature. Background technique [0002] The ground test of aerospace products often needs to be carried out in environmental simulation equipment. The environmental simulation equipment simulates the vacuum and low temperature environment similar to the space environment through vacuum acquisition components and low temperature acquisition components, and performs performance tests or simulation experiments on the products in the tank. [0003] Under certain advanced test requirements, a solar simulator must be configured. The solar simulator is fixed in the environment simulation equipment, and aerospace products need to move around the solar simulator. Therefore, the test equipment (hereinafter referred to as motion simulator) must have the ability to lift, rotate or move under vacuum and low temperature. [0004] The ...
