Embodiment Construction

[0010] The specific embodiments of the present invention are given below with reference to the accompanying drawings, which are used to further describe the composition of the present invention in detail.

[0011] The water pump bearing of this embodiment includes an outer ring 91, a mandrel 92, a double-lip sealing ring 68, a ball retainer 46, a column retainer 26, a roller 24 and a steel ball 4, and the roller 24 is installed on the column retainer 26. In the window hole, the steel ball 4 is installed in the pocket of the ball cage 46, the outer ring 91 and the mandrel 92 are processed with grooves and raceways, the steel ball 4 rolls in the groove, and the roller 24 rolls on the raceway. The outer diameter of the double-lip sealing ring 68 is installed in the groove of the sealing ring of the outer ring 91, and the inner diameter of the double-lip sealing ring 68 is connected with the mandrel 92, and the double-lip sealing ring 68 is made of NBR.

Abstract

The present invention relates to a water pump bearing, and belongs to the technical field of bearing equipment. The water pump bearing comprises an outer ring, a core shaft, a double lip sealing ring, a ball retainer, column retainers, rolling columns and a steel ball, wherein the rolling column is arranged in the window hole of the column retainer, the steel ball is arranged in the pocket hole of the ball retainer, groove channels and rolling channels are processed on the outer ring and the core shaft, the steel ball rolls in the groove channel, the rolling column rolls in the rolling channel, the outer diameter of the double lip sealing ring is arranged in the sealing ring threaded groove of the outer ring, the inner diameter of the double lip sealing ring is connected with the core shaft, and the double lip sealing ring is made from a nitrile butadiene rubber. According to the water pump bearing of the present invention, the ball retainer, the column retainer and the double lip sealing ring are additionally arranged on the base of the existing bearing, such that the falling out of the rolling body during the installation and the disassembly is prevented, it is ensured that the bearing does not produce the oil leakage condition, and the invasion of external impurities is prevented; and the specified column end radial dynamic load of the present invention is increased by 25 KN compared with the specified column end radial dynamic load of the previously-designed structure, such that advantages of high bearing capacity, long service life, good rigidity, high rotation degree and the like are provided, and the failure rate is almost zero after the water pump bearing is used by customers.

Description

technical field [0001] The invention relates to a bearing for a water pump and belongs to the technical field of bearing equipment. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. The main problems of existing bearings used in water pumps are low load-carrying capacity, high bearing failure rate and short service life. Contents of the invention [0003] The object of the present invention is to solve the shortcomings of the above-mentioned prior art...
