Abstract

The invention discloses a driving loading platform under a low-temperature vacuum condition, the platform comprises a driving device, a loading device, a first heat insulation coupling, a second heat insulation coupling, a third heat insulation coupling, a first torque sensor, a temperature-controllable vacuum box, a normal temperature box and a test piece; the normal temperature box is arranged in the controllable vacuum box; the driving device and the loading device are installed in the normal temperature box, the test piece is arranged in the temperature-controllable vacuum box, the output end of the loading device is connected with a loading input end of the test piece, and the driving device is connected with a driving end of the test piece; according to the invention, the servo motor can be arranged in the normal-temperature box formed by fixing the normal-temperature box body and the normal-temperature box end cover through screws, so that the large-torque and high-rotating-speed test requirements can be met, and driving and loading outside a vacuum tank are not needed; when the test is completed, a special vacuum tank does not need to be customized, only the mounting platform needs to be put down, the length of a transmission chain is greatly shortened, and the coaxiality is easy to guarantee.

Description

technical field [0001] The invention relates to the field of driving loading test under low temperature vacuum condition, and more specifically relates to a driving loading platform under low temperature vacuum condition. Background technique [0002] There is a brake applicable to the aerospace field, and the purpose of the device is to decelerate the rotating shaft until it stops rotating. The main working environment of this type of brake is a low-temperature vacuum environment. Its main principle is: use the friction pair in the brake to generate and prevent the torque of the rotating shaft, so that the target shaft decelerates until it stops rotating. In order to study the performance, life and other characteristics of the brake under different working conditions, different environments, and different steering directions, it is necessary to carry out corresponding simulation tests on the ground. [0003] In order to complete the ground simulation test of the brake, it ...
