Description

Technical Field

[0001] The utility model relates to the technical field of bearing technology, in particular to an anti-seizure graphite bearing for a water pump. Background Art

[0002] The reason why anti-seize water pump graphite bearings are needed is that they have excellent self-lubrication, wear resistance and high temperature resistance, which can effectively reduce friction and wear and prevent the bearings from seizing during operation.

[0003] For example, in a type of prior art represented by application number CN201921503851.2, its main structure includes a graphite tube, the hollow interior of which is composed of a first cylindrical segment, a second cylindrical segment and a third cylindrical segment in sequence. The problem of shrinkage and deformation of the graphite bearing is solved by expanding the inner diameter of both ends of the graphite tube and adding a stainless steel sleeve and a positioning step.

[0004] During use, it was found that the water pump impeller of the existing electronic water pump rotates at high speed around the pump shaft during operation. Usually, in order to reduce the noise and vibration of the water pump, the gap between the water pump impeller bearing and the pump shaft is very small. However, there will be impurities from internal parts or the outside world in the vehicle pipeline. The impurities are embedded in the gap between the impeller bearing and the pump shaft, which can easily cause the water pump impeller to get stuck, making the water pump unable to operate and the vehicle cooling system fail. Therefore, there is an urgent need for a water pump graphite bearing that prevents getting stuck. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an anti-stuck water pump graphite bearing which removes impurities through spiral grooves, improves safety through chamfers, and facilitates installation of the water pump graphite bearing on the water pump through mounting grooves.

[0006] The utility model discloses a water pump graphite bearing that is anti-stuck, comprising a water pump graphite bearing; the water pump graphite bearing is provided with a spiral groove, a chamfer and a mounting groove; the spiral groove serves to exclude impurities, the chamfer improves safety, and the mounting groove facilitates installation; the spiral groove serves to exclude impurities, the chamfer improves safety, and the mounting groove facilitates installation of the water pump graphite bearing on the water pump.

[0007] Preferably, the inner diameter of the water pump graphite bearing is 6 mm; since the inner diameter of the water pump graphite bearing is 6 mm, it is convenient to install the water pump graphite bearing on the water pump.

[0008] Preferably, the water pump graphite bearing is provided with a spiral groove, which is clockwise and runs through the entire water pump graphite bearing; the spiral groove prevents impurities from being stuck between the shaft and the bearing.

[0009] Preferably, the spiral groove depth is R0.6mm, the spiral angle is 15°, and the height is 19.6mm; by making the spiral groove depth R0.6mm, the spiral angle 15°, and the height 19.6mm, it is ensured that all angles are not affected by impurities.

[0010] Preferably, the water pump graphite bearing is provided with a chamfer; the chamfer improves safety and aesthetics.

[0011] Preferably, the water pump graphite bearing is provided with a mounting groove; the water pump graphite bearing can be conveniently mounted on the water pump through the mounting groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the spiral groove can remove impurities, the chamfer can improve safety, and the installation groove can facilitate the installation of the water pump graphite bearing on the water pump.
