Integrated four-point contact ball bearing with heart-shaped roller paths

Abstract

An integrated four-point contact ball bearing with heart-shaped roller paths is mainly formed by assembling of an outer ring, an inner ring, a plurality of steel balls, a holding rack seat and a holding rack cover. Each steel ball is arranged in a corresponding bag hole of the holding rack seat, the holding rack seat containing the multiple steel balls is arranged in the roller paths formed by the outer ring and the inner ring, the holding rack cover is arranged on the holding rack seat, and the holding rack seat and the holding rack cover are fixedly connected through a plurality of rivets. The integrated four-point contact ball is characterized in that the inner ring is of an integrated structure, the two heart-shaped roller paths in contact with the steel balls are formed in the outer wall of the inner ring, and an included angle of 35 degrees is formed between the roller paths and the steel balls. The integrated four-point contact ball bearing has the beneficial effects that the heart-shaped groove type roller paths are machined in the integrated structural style of the inner ring, it is guaranteed that the steel balls can be locked in the roller paths well, and the use advantages of an original four-point contact ball are achieved. It is avoided that in the use and loading process, due to the fact that steel balls cannot be locked in roller paths, the steel balls fall off, the use stability of the bearing is improved, and the service life of the bearing is prolonged.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to an integral four-point contact ball bearing with a peach-shaped raceway that prevents the rolling elements from being locked in the raceway due to insufficient height of the locking point and resulting in loose sets. Background technique [0002] The four-point contact ball bearing of the traditional structure is a radial single-row angular contact ball bearing, and the raceways are designed to support axial loads acting in two directions. Compared with double row bearings, this type of bearing occupies significantly less axial space. The inner ring is a split inner ring, which allows a large number of steel balls to be loaded into the bearing, thus giving the bearing a higher load bearing capacity. The bearing is a separate design, that is, the outer ring with steel balls and cage components can be The two half-rings of the inner ring are installed separately, and the outer ri...

AI Technical Summary

Problems solved by technology

Due to the separate design of the bearing, it is easy to fall apart during transportation, installation and use, resulting in the failure of the normal use of the bearing and affecting the entire production system

Moreover, frequent replacement of bearings will also increase production costs. The structural form of the traditional four-point contact ball bearing is difficult to meet the requirements of use, and the traditional structure needs to be optimized and improved.
