The outer rings are arranged relative to each other so that two trapezoidal half-slots with a small mouth, a large bottom and a small bottom are respectively arranged on the opposite ends of the two halves of the outer rings to communicate with each other. The outer ring is formed to be sleeved on the outside of the inner ring, and a plurality of balls are respectively partially placed in the circular grooves of the two half rings.

In the ball bearing, the outer walls of the half outer rings respectively provided on the two half outer rings are combined to form an annular plane structure.

In the ball bearing, the inner wall of the inner ring provided on the inner ring is an annular plane structure.

In the ball bearing, a chamfering transition is set between the inner wall of the inner ring and the two end faces of the inner ring.

In the ball bearing, ring grooves are respectively provided at both ends of the outer wall of the inner ring of the inner ring.

In the ball bearing, circlips are respectively sleeved in the two ring grooves, and the outer edge surfaces of the two circlips are respectively in contact with the two ends of the combined inner walls of the two half outer rings.

In the ball bearing, joints are respectively provided on the two retaining springs.

In the ball bearing, there is an interference fit between the trapezoidal semi-slotted groove and the trapezoidal snap ring.

Owing to adopting the above-mentioned technical scheme, the utility model has the following beneficial effects:

The ball bearing of the utility model, by placing the ball in the ball socket provided on the outer wall of the inner ring, and setting the outer ring as a structure composed of two halves of the outer ring, the distance between the outer ring and the inner ring is reduced. It can be shortened as much as possible, and the purpose of preventing the bearing oil smeared on the bearing from being easily thrown out during high-speed operation is realized; the utility model has novel and unique design, strong practicability, energy saving and consumption reduction, and has great market promotion value.
