Vehicle special-shaped bearing narrow inner ring

Abstract

The invention belongs to the technical field of automobile parts and relates to a vehicle special-shaped bearing narrow inner ring. The invention aims at solving the technical problem of unstable operation in the prior art. The vehicle special-shaped bearing narrow inner ring comprises an inner ring body, wherein a shaft hole is formed in the inner ring body, a first retaining ring is arranged at one end of the inner ring body, a second retaining ring is arranged at the other end of the inner ring body, the outer diameter of the first retaining ring is larger than that of the second retaining ring, the outer wall of the inner ring body between the first retaining ring and the second retaining ring forms a tapered outer inclined plane, the outer inclined plane, the first retaining ring and the second retaining ring encircle to form a ball groove for accommodating a ball, the surface of the first retaining ring, which is positioned in the ball groove, has a tapered first retaining ring inclined plane, the surface of the second retaining ring, which is positioned in the ball groove, has a tapered second retaining ring inclined plane, the included angle alpha between the first retaining ring inclined plane and the outer inclined plane is more than 89 degrees and less than 90 degrees, and the included angle beta between the second retaining ring inclined plane and the outer inclined plane is more than 90 degrees and less than 91 degrees. The vehicle special-shaped bearing narrow inner ring provided by the invention is reasonable in design, stable in operation and good in loading performance.

Description

technical field [0001] The invention belongs to the technical field of auto parts and relates to a narrow inner ring of a special-shaped bearing for vehicles. Background technique [0002] Bearings are one of the most widely used components in mechanical engineering or automobiles. Most bearings mainly include outer rings, rolling elements, cages, and inner rings. The inner ring of the bearing is in direct contact with the surface of the shaft. The inner ring of the existing bearing easily causes the rolling elements to run off, and the rolling is inflexible and unstable during work, and in severe cases, the entire bearing will be scrapped. [0003] In order to solve the problems existing in the prior art, people have carried out long-term exploration and proposed various solutions. For example, the Chinese patent literature discloses a bearing inner ring [patent number: CN 102537079 A], which includes a bearing inner ring body, and circular grooves are symmetrically opene...
