Water pump bearing

Abstract

The invention particularly relates to a water pump bearing, and belongs to the technical field of bearings. The water pump bearing comprises a bearing mandrel; a bearing ring is arranged on the outer surface of the bearing mandrel in a sleeved mode; a ring raceway is arranged in the bearing ring; a steel ball retainer is arranged on the outer surface of the bearing ring; a steel ball body is placed on the inner surface of a steel ball placing groove in the steel ball retainer; a sealing oil seal is arranged on the left side of the bearing ring in a sealed mode; the right side of the bearing ring is of an open structure; the sealing oil seal is arranged on the left side of the bearing ring in a sealed mode, thus engine oil can be prevented from leaking out; the right side of the bearing ring is of an open structure and is not sealed, and therefore after the engine oil enters the bearing, the pressure in the bearing cannot be increased, and the engine oil does not seep out, the internal engine oil can directly flow into the bearing to help the bearing to be lubricated, so that the friction of the bearing is reduced, and the service life of the bearing is prolonged.

Description

technical field [0001] The invention specifically relates to a water pump bearing, which belongs to the technical field of bearings. Background technique [0002] In the process of motorcycle production and processing, many mechanical parts are needed, and bearings are an important part of motorcycle mechanical parts. Its main function in the connection of motorcycle mechanical parts is to support the mechanical rotating body, reduce the friction coefficient during its movement, and at the same time ensure the effect of its rotation accuracy. [0003] However, the existing water pump bearings have some deficiencies in the process of use. First, the existing bearings often use double-sided sealing, which causes a large pressure difference inside the bearing under high temperature conditions, which easily causes oil leakage. The second is After the existing bearing is sealed, it is not convenient for the machine oil to flow into the interior of the bearing for lubrication, wh...

Problems solved by technology

[0003] However, the existing water pump bearings have some deficiencies in the process of use. First, the existing bearings often use double-sided sealing, which causes a large pressure difference inside the bearing under high temperature conditions, which easily causes oil leakage. The second is After the existing bearing is sealed, it is not convenient for the oil to flow into the inside of the bearing for lubrication, which makes the friction of the bearing relatively large and shortens the practical life of the bearing.
