ROLLING BEARING OF SHAFT Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: rolling bearing has a radial-thrust bearing mounted on a step-shaped race by facing wide faces of inner races each other. The wide faces of the inner bearings are provided with ring grooves of the bearings which are matted with answered surfaces of the step- shaped race. The step-shaped race is provided with an axial passage which form closed chamber, filled with hydro-plastic, with the ring grooves and the faces of the steps of the step-shaped race. The outer races of the bearings are spaced by a distant bushing. The bearing is mounted on the shaft. EFFECT: enhanced reliability and longevity of the bearing. 1 dwg
