ROLLING BEARING OF SHAFT Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: rolling bearing has a journal of a shaft, two radial-thrust rolling bearings mounted for facing narrow faces of inner races each other, and unit for providing axial tension. The rolling bearing is provided with a step-shaped race having at least one axial passage and mounted on outer races of the bearings. Outer races are provided with ring grooves from the side of wide faces . The unit for providing axial tension is made of a closed chamber filled with hydro-plastic. The chamber is formed with the ring grooves of outer races, faces of steps of step-shaped race, and axial passage. EFFECT: enhanced reliability and longevity of the rolling bearing. 1 dwg
