Rolling bearing with three-arc roller surface

Abstract

The invention provides a rolling bearing with a three-arc roller surface. The rolling bearing comprises an inner ring, an outer ring, a roller and a holder, wherein the surface of the roller comprises three arcs which are smoothly connected. The surface of the roller is changed into three jointed arcs, so that friction and collision between the roller and a ferrule roller path are reduced, the arcs of the surface of the roller and the arcs of the surface of the ferrule roller path are in well fit, the service life of the bearing is prolonged, the replacement time of the equipment is reduced, and the production cost is saved.

Description

technical field [0001] The invention relates to a rolling bearing, in particular to a rolling bearing with three circular arc roller surfaces. Background technique [0002] Rolling bearing is a precision mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling body and cage. The function of the inner ring is to cooperate with the shaft and rotate together with the shaft; the function of the outer ring is to cooperate with the bearing seat to play a supporting role; The cage evenly distributes the rolling elements between the inner ring and the outer ring, and its shape, size and quantity directly affect the performance and life of the rolling bearing; the cage can evenly distribute the rolling elements, prevent the rolling elements from falling off, and guide the rolling elements The rotation a...
