Abstract
The utility model discloses a rolling bearing with a roller provided with a three-circular-arc surface. The rolling bearing with the roller provided with the three-circular-arc surface comprises an inner ring, an outer ring, the roller and a retainer. The surface of the roller is composed of three sections of circular arcs, and the three sections of the circular arcs are in smooth connection. Due to the fact that the surface of the roller is changed into a form with the three circular arcs connected, friction and collision between the roller and a ferrule rollaway nest are reduced. Due to the fact that the circular arcs of the surface of the roller and a circular arc of the surface of the ferrule rollaway nest are well fitted, the service life of the bearing is prolonged, replacement times of equipment are reduced, and production cost is saved.
Description
Technical field
The utility model relates to a kind of rolling bearing, specifically, is a kind of rolling bearing of three-arc roller surface.
Background technique
Rolling bearing is that the axle of running and the sliding friction between the axle bed are become rolling friction, thus the mechanical component of a kind of precision of the loss of reducing friction.Rolling bearing generally is comprised of inner ring, outer ring, rolling element and retainer four parts, and the effect of inner ring is to match to merge with axle to rotate together with the axis; The outer ring effect is to match with bearing support, plays a supportive role; Rolling element is uniformly rolling element to be distributed between inner ring and the outer ring by means of retainer, and its shape size and quantity directly affect usability and the life-span of rolling bearing; Retainer can make rolling element evenly distribute, and prevents that rolling element from coming off, guiding rolling element rotation lubricate.This bearing mainly was easily fatigue flake in the middle of the roller after use a period of time in the past, work as afterwards by analysis bearing in the carrying situation, roller surface circular arc and lasso raceway face arc contact surface cause, and former roller surface circular arc is that one circular arc forms, and bearing is easily damaged.Only have the roller surface circular arc is improved, just can address this problem.
The model utility content
The purpose of this utility model provides a kind of rolling bearing of three-arc roller surface, owing to using the roller on three-arc surface, has solved the serious problem of roller and lasso raceway friction.
Technical solution of the present utility model is:
A kind of rolling bearing of three-arc roller surface comprises inner ring, outer ring, roller and retainer, and the surface of described roller is comprised of three sections circular arcs, is smoothly connected between every section circular arc.
Further be: the chord length of circular arc is greater than the chord length of both sides circular arc in the middle of described three sections circular arcs.
The beneficial effects of the utility model are: the form that the surface of roller is changed into three circular arc dovetails, frictional impact between minimizing and the lasso raceway, it is very good that roller surface circular arc and lasso raceway face circular arc are fitted, improved bearing life, reduce the replacing number of times of equipment, saved cost of production.
