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...
