Problems solved by technology

During the working process of the bearing, the inner ring of the bearing rotates together with the transmission shaft, and the inner ring of the bearing drives the rolling body to rotate. When the transmission shaft runs at high speed, the speed of the rolling body also increases, and the friction force increases. It is easy to cause damage to the raceway of the bearing, which greatly reduces the service life of the bearing

Embodiment Construction

[0013] The structure of the ball bearing is as follows: a ring-shaped double-row ball raceway is arranged between the bearing outer ring 1 and the bearing inner ring 2, and two rows of balls 4 are arranged on the ring-shaped double-row ball raceway. The anti-friction cage 3 of the arranged half-moon concave position 5.

[0014] The ball 4 is a spherical structure made of silicon nitride ceramics.

[0015] The anti-friction cage 3 is a cage with evenly arranged half-moon-shaped recesses 5 structures, and the middle position of the half-moon-shaped recesses 5 structures has a lubricating hole of a specific shape, and the lubricating material is polytetrafluoroethylene.

[0016] The lubricating hole of the specific shape can be an I-shaped or rectangular structure, preferably an I-shaped structure, which can effectively reduce the friction between the ball and the raceway.

Abstract

The invention relates to a ball bearing. The ball bearing is structurally characterized in that an annular dual-row ball roller path is arranged correspondingly between a bearing outer ring and a bearing inner ring; two columns of balls are arranged on the annular dual-row ball roller path; half-moon-type concave antifriction retainers which are arrayed uniformly are placed among the balls; and I-shaped or rectangular structural lubrication holes are arranged at the middle position of the half-moon-type concave structure. The friction between the balls and the roller path can be reduced effectively by the structure; teflon materials are adopted as lubrication materials, which is good for prolonging the service life of the bearing; and the teflon materials have the advantages of extremely low friction coefficient, high self-lubrication capability, abrasion resistance, high-temperature resistance and the like.

Description

technical field [0001] The invention relates to a rolling bearing, in particular to a ball bearing used in high-speed running conditions. Background technique [0002] The invention relates to the field of bearing manufacturing, in particular to a ball bearing with a simple structure, which is applied under the condition of high-speed operation. During the working process of the bearing, the inner ring of the bearing rotates together with the transmission shaft, and the inner ring of the bearing drives the rolling body to rotate. When the transmission shaft runs at high speed, the speed of the rolling body also increases, and the friction force increases. It is easy to cause damage to the raceway of the bearing, which greatly reduces the service life of the bearing. Contents of the invention [0003] In view of the defects in the prior art, the object of the present invention is to provide a ball bearing with a small friction coefficient and good wear resistance.
