STAND FOR TESTING THE ANTIFRICTION BEARINGS Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: stand has stator, rotor for installation of bearings under test made in the form of two hollow shafts coupled by means of flanges, pneumatic system, axial loader, and information-measuring system. Throttles are installed in external ends of hollow shafts. Axial loader has n elements but not less than two. One of elements in pairs is made with unbalance relative to element which is opposite to it. Internal surfaces of shafts on the side of flanges are of conical or spherical form. Turbine blades are positioned on them at sharp angle. Pneumatic system includes compressor and vacuum pump. Pressure sensing elements in pairs are made as blades of semicircular, semielliptic or rectangular form. They may be manufactured as cups of different mass. EFFECT: higher test results. 8 cl, dwg
