DEVICE FOR RESEARCH FIELDS fluid pressure in the gap friction surfaces

摘要

An apparatus for investigating fluid pressure field in the nip friction surfaces designed to study fluid pressure fields in radial clearances of the rubbing surfaces. The apparatus comprises a stepped housing (1) concentrically with the shaft mounted in the housing (2) and inlet openings (3) and outlet (4) of the working medium. On the shaft (2) is fixed disc (5) to form a step between the body (1) and the disc (5) a radial gap (6). The stage housing (1) opposite the disc (5) arranged on the diameter line of the disc (5) a sensor (7) and pressure sensor (8) of the gap. inlet opening (3) of the working medium is hydraulically connected to a pump (9) and outlet opening (4) of the work environment - a tank (10) hydraulically connected to a pump (9). Enabling studies fluid pressure fields in radial gaps rubbing surfaces achieved by making the body stepwise, the disc fixing the shaft to form a step between the housing and the disc radial clearance and placing pressure sensors and a gap in the housing on the stage disc diameter line.; 4 ZP f ly-1-yl.
