Embodiment Construction
[0015] The present invention will be further described below in conjunction with specific drawings.
[0016] Such as figure 1 As shown, a water pump integrated bushing according to the present invention includes a long cylindrical bushing body 1, the bushing body 1 includes a bearing part 2 and a bushing part 3, and the bearing parts 2 are respectively located in the bushing The two ends of the part 3, the bearing part 2 and the shaft sleeve part 3 are integrally formed; the joints of the bearing part 2 and the shaft sleeve part 3 are respectively provided with oil storage tanks 4, and the oil storage tanks 4 can store a certain amount of lubricating grease for sufficient lubrication, and also play a role. The inner diameter of the bearing part 2 is greater than the inner diameter of the shaft sleeve part 3. When in use, the graphite bearings assembled at both ends are in loose contact with the inner diameter of the bearing part 2.
[0017] The outer diameter of the shaft sle...

Abstract
The invention relates to a water pump integrated shaft sleeve. The water pump integrated shaft sleeve comprises a long cylindrical shaft sleeve body. The shaft sleeve body comprises bearing portions and a shaft sleeve portion, the bearing portions are located at the two ends of the shaft sleeve portion respectively, and the bearing portions and the shaft sleeve portion are integrally formed; oil storage grooves are formed in the joints between the bearing portions and the shaft sleeve portion; and the inner diameter of the bearing portions is larger than that of the shaft sleeve portion. According to the water pump integrated shaft sleeve, the bearing portions at the two ends are changed into the integrated connecting-shaped shaft sleeve, and stainless steel materials are adopted, so that the inner diameter roughness is reduced; and proper lubricating oil is injected into the oil storage grooves, so that the effect of dust prevention and water proofing in the operation process of a bearing is achieved, the friction is reduced, the heat generation effect is reduced, and the service life of the product is prolonged.
Description
technical field [0001] The invention relates to an integrated shaft sleeve of a water pump, which is applied in the field of new energy vehicles. Background technique [0002] It is used as a shaft sleeve fitting on the water pump shaft of a new energy vehicle; the auxiliary rotating bearings at both ends of the interior adopt a loose fit design, and a tight fit design between the bearing and the shaft. Due to the high water content and high rotational friction in the working conditions of the water pump, the shaft between the two bearings is prone to water and dust, resulting in premature failure and short service life. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide an integrated shaft sleeve for water pumps, which changes the bearing chambers at both ends into an integrated connected shaft sleeve, and uses stainless steel materials to reduce the roughness of the inner diameter, and the ...
