Abstract

The invention designs a test device for a radial static pressure gas bearing experiment. The test device mainly consists of a spindle system module and a loading mechanism module. The spindle system module includes a computer table, a computer, a rack, a driving motor, a coupling, radial static pressure gas bearings, a spindle, micro displacement sensors, and micro displacement sensor brackets. The loading mechanism module includes parallel wheels, a loading bearing, a circular leather sheath, a tension rope, a bearing rod, a spring dynamometer, a weight disc, supporting frames, an upper supporting plate, a guide rail, a worm gear, a handwheel, and a lower supporting plate. The spindle in the spindle system is carried by the two radial static pressure gas bearings. Displacement detection is carried out on the spindle by the three micro displacement sensors. One end of the spindle is driven by the driving motor through the coupling, and the other end is loaded by the loading mechanism through the loading bearing. The test device for the radial static pressure gas bearing experiment can test the static stiffness and dynamic stability load of the radial static pressure gas bearings, adopts the special loading mechanism, can load the spindle from any angle in the radial direction, and can adjust the height of the loading.

Description

Technical field [0001] The invention relates to the field of gas bearings, in particular to an experimental test device for radial static pressure gas bearings. Background technique [0002] At present, there are few experimental methods for radial static pressure gas bearings in China, and the method is relatively single. Most experimental devices can only conduct experiments on specific bearings, and the test efficiency is low. When carrying out experiments related to radial static pressure gas bearings, the general load loading method is the suspension method. The traditional suspension method uses the method of directly hanging weights on the main shaft, which can only test the bearing performance of the main shaft system when it is static. Contents of the invention [0003] The purpose of the present invention is to provide a radial static pressure gas bearing experimental testing device, so that the loading mechanism can load the spindle system from any angle along ...
