Ball bearing with steel ball omni-directional rolling function

Abstract

The invention discloses a ball bearing with a steel ball omni-directional rolling function. The ball bearing comprises an outer ring 1, a holding frame 2, a rolling body 3 and an inner ring 4, wherein the inner surface ball track of the outer ring 1 is an asymmetric arc-shaped conical surface; the outer surface ball track of the inner ring 4 is a pure circular arc surface; a lubricating oil groove is formed between the inner surface ball track of the outer ring 1 and the rolling body 3; and the rolling body 3 is arranged and freely rolls between the arc-shaped conical surface ball track of the outer ring 1 and the pure circular arc surface of the inner ring 4. The ball bearing has the advantages that the arc-shaped conical angles of the two sides of the arc-shaped conical surface of the inner surface ball track of the outer ring 1 are different, so that steel balls can rotationally roll in the side direction when revolving along the asymmetric arc-shaped conical surface ball track, and then the full-surface uniform contact between the steel balls and the asymmetric arc-shaped conical surface ball track in a bearing working process can be achieved.

Description

technical field [0001] The invention relates to a steel ball omni-directional rotating ball bearing, which belongs to the technical field of ball bearings, in particular to a new type of ball bearing. Background technique [0002] Through observation, it is found that the wear area on the surface of the steel ball is relatively concentrated, and obvious fatigue wear appears in the wear area, and the surface of the steel ball in the same bearing has this feature. The structure of the bearing raceway directly affects the state of the steel ball inside the bearing. At present, the rolling form of the steel ball in the ball bearing raceway cannot be effectively controlled. The surface contact points are subject to high-frequency contact stress, resulting in a relatively fixed wear area. The service life of the steel ball and raceway is reduced, which affects the performance of the entire bearing; in addition, the radial load capacity of the ball bearing is small. If complex and ...

The structure of the bearing raceway directly affects the state of the steel ball inside the bearing. At present, the rolling form of the steel ball in the ball bearing raceway cannot be effectively controlled. The surface contact points are subject to high-frequency contact stress, resulting in a relatively fixed wear area. The service life of the steel ball and raceway is reduced, which affects the performance of the entire bearing; in addition, the radial load capacity of the ball bearing is small. If complex and heavy loads occur, it is easy to cause the lubricating oil film to break and the lubrication to fail, directly reducing the service life of the steel ball. , affecting the entire bearing life
