Compared with the prior art, the automobile water pump has the following advantages and effects that a traditional automobile water pump formed by connecting two deep groove ball bearings is changed into the integrated shaft connecting bearing, the installation efficiency can be effectively improved, meanwhile, the service life is prolonged, and the automobile water pump can be rapidly maintained when damaged.

Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a low-resistance, high-sealing automotive water pump shaft bearing. Background Technology

[0002] Traditional automotive water pumps use 6302 deep groove ball bearings. This existing method requires installing two deep groove ball bearings on one shaft, which is complex and time-consuming. Furthermore, these bearings are prone to damage after a certain period of use, thus affecting the lifespan of the automotive water pump. This structure also presents difficulties in repair after damage. Utility Model Content

[0003] The purpose of this invention is to provide a low-resistance, high-sealing automotive water pump shaft bearing.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a low-resistance, high-sealing automotive water pump shaft bearing, including a bolt shaft, with an outer layer provided outside the bolt shaft; both the inner wall of the bolt shaft and the inner wall of the outer layer are provided with two parallel annular grooves; multiple steel balls are provided in the annular groove between the bolt shaft and the outer layer; and stop rings that abut against the inner wall of the outer layer are provided on both sides of the bolt shaft.

[0005] The stop ring is further configured such that: the stop ring includes a turning body, the turning body has an inclined portion from the inside to the outside, the outer end of the turning body is provided with a hook portion, and the inner wall of the outer layer is provided with a groove, the hook portion being embedded in the groove.

[0006] The design further includes: a sealing block integrally formed at the inner end of the turning body, and several layers of J-shaped blocks formed on the sealing block, with the tips of the J-shaped blocks facing outwards.

[0007] A further configuration is provided: a retainer is provided between the bolt shaft and the outer layer, and steel balls are disposed within the retainer.

[0008] In summary, this utility model has the following beneficial effects: by replacing the traditional car water pump connected by two deep groove ball bearings with an integrated shaft bearing, the installation efficiency can be effectively accelerated, the service life can be improved, and repairs can be carried out quickly in case of damage.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings.

[0013] A low-resistance, high-sealing automotive water pump shaft bearing includes a bolt shaft 1, with an outer layer 2 disposed outside the bolt shaft 1.

[0014] Two parallel annular grooves 3 are provided on both the inner wall of the bolt shaft 1 and the inner wall of the outer layer 2. Multiple steel balls 4 are placed in the parallel annular grooves 3. The outer ends of the steel balls 4 abut against the annular grooves 3 of the outer layer 2, and the inner ends abut against the annular grooves 3 of the bolt shaft 1. The steel balls 4 can roll along the annular grooves 3.

[0015] Both sides of the bolt shaft 1 are provided with stop rings 5 ​​that abut against the inner wall of the outer layer 2. The stop ring 5 includes a bending body 6, which has an inclined portion 7 from the inside out. The two ends of the inclined portion 7 are parallel and vertical as shown in the figure. The outer end of the bending body 6 is provided with a hook portion 8, and the inner wall of the outer layer 2 is provided with a groove 9, into which the hook portion 8 is embedded.

[0016] The inner end of the turning body 6 is integrally provided with a sealing block 10, and the sealing block 10 is provided with several layers of J-shaped blocks 11, with the tips of the J-shaped blocks 11 facing outward. When dust or debris enters from the outside, it can be blocked at the tip of the J-shape, thereby achieving a high sealing effect.

[0017] A retainer 12 is provided between the bolt shaft 1 and the outer layer 2, and the steel balls are disposed inside the retainer 12.

[0018] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
