Description

Technical Field

[0001] The utility model relates to the technical field of shafts, in particular to an anti-wear shaft for a high-power water pump. Background Art

[0002] In electronic water pumps, such as the one disclosed in the utility model patent with publication number CN212337704U, which has a protective structure for the impeller bearing in an electronic water pump, and the one disclosed in the utility model patent with publication number CN210152986U, the impeller of the water pump rotates at high speed around the pump shaft during operation. Usually, a wear-resistant ceramic gasket is placed between the impeller and the volute to prevent the upward force of the impeller from wearing away the plastic volute. In the design of low-power water pumps, the ceramic gasket and the shaft each have a limiting flat position to prevent the impeller from rotating with the ceramic gasket, such as Figure 5 shown.

[0003] However, during use, it was found that since the hardness of the ceramic gasket is much higher than that of the shaft, the ceramic gasket will cause great wear on the shaft during the continuous starting and stopping process. Eventually, the flat part of the shaft will be worn flat, resulting in anti-rotation failure, resulting in poor practicality. Therefore, there is an urgent need for a ceramic gasket that can prevent high-power water pumps from cracking to improve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a high-power water pump anti-wear shaft that mounts a ceramic gasket on the limiting structure of the shaft body. When the impeller rotates and drives the ceramic gasket to rotate, the six sides of the limiting structure contact the ceramic gasket, which is beneficial to sharing the force per unit area, thereby reducing the wear of the shaft body, increasing the service life of the shaft body, and reducing the failure rate of the electronic water pump.

[0005] The utility model discloses a wear-resistant shaft for a high-power water pump, comprising a shaft body; a limiting structure is provided on the shaft body, and the limiting structure is a regular hexagon;

[0006] The ceramic gasket is mounted on the limiting structure of the shaft body. When the impeller rotates and drives the ceramic gasket to rotate, the six sides of the limiting structure contact the ceramic gasket, which is beneficial to distributing the force per unit area, thereby reducing the wear of the shaft body, increasing the service life of the shaft body, and reducing the failure rate of the electronic water pump.

[0007] Preferably, each side of the regular hexagon of the limiting structure has a length of 7 mm.

[0008] Preferably, the limiting structure on the shaft body may also be in a plum blossom shape; when the impeller of the electronic water pump rotates, the plum blossom-shaped limiting structure distributes the force per unit area, which is beneficial to distributing the force per unit area, thereby reducing the wear of the shaft body, increasing the service life of the shaft body, and reducing the failure rate of the electronic water pump.

[0009] Preferably, the corners of the plum blossom-shaped limiting structure are all rounded.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The polygonal and plum blossom-shaped shaft structure effectively reduces the force on the shaft, thereby reducing shaft wear;

[0012] 2. The shaft is made into a simple polygonal or plum blossom-shaped structure, which can not only prevent rotation but also reduce stress;

[0013] 3. The process is simple and can be achieved through machining. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The ceramic gasket 3 is mounted on the limiting structure 2 of the shaft body 1. When the impeller rotates and drives the ceramic gasket to rotate, the six sides of the limiting structure 2 contact the ceramic gasket 3, which is beneficial to distributing the force per unit area, thereby reducing the wear of the shaft body 1, increasing the service life of the shaft body 1, and reducing the failure rate of the electronic water pump.
