The invention discloses a static-pressure bearing test stand which comprises a spindle, a motorized spindle system, a bearing housing, a front hydrostatic-pressure bearing, a rear hydrostatic-pressure bearing, a bearing connection shaft, a vertical loading device, a left coupler, a right coupler, a direct-current motor and a test-stand support frame. The bearing connection shaft is fixedly connected with the spindle, the vertical loading device is arranged on the left side of the bearing housing, the left coupler is used for connecting the bearing connecting shaft with a torque sensor, the right coupler is used for connecting the torque sensor with the direct-current motor, and the direct-current and the test-stand support frame are arranged on the rightmost side. The motorized spindle system of the test stand is arranged on the left side of the bearing housing, the front end and the back end of the spindle are supported on the bearing housing through the front hydrostatic-pressure bearing and the rear hydrostatic-pressure bearing respectively, a hydraulic axial thrust plate is arranged at the right end of the rear hydrostatic-pressure bearing, applied loads are exerted on the bearing connection shaft, and the torque sensor and the direct-current motor are mounted at the right end of the bearing connection shaft.
Description
technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and more specifically relates to a static pressure support test bench. Background technique [0002] Ultra-precision machined parts have been widely used in both national defense technology and civilian technology. With the advancement of science and technology, the precision requirements of parts are getting higher and higher, and the size requirements are getting bigger and bigger. The supporting components on traditional machine tools such as ball screws, ball guide rails, and dynamic pressure sliding bearings can no longer meet the accuracy of ultra-precision machining and measurement. and stability requirements. Hydrostatic bearing parts have been more and more widely used due to their advantages of high precision, small friction, stable operation and long life. In recent years, foreign research on hydrostatic bearings is developing in the direction of large-scale, heavy-d...
