Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a high-sealing water pump bearing. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The water pump bearing is a bearing placed on the water pump, which is inserted into the inner ring of the bearing through an external mandrel. It has high precision requirements and high sealing requirements.

[0003] The existing water pump bearings have poor sealing performance, which causes foreign impurities to enter the bearings and affect the bearing speed, which in turn affects the use of the water pump. When the water pump is working, the water pump shaft rotates at high speed, so it is easy to slip with the bearings, which in turn causes sealing failure. For this reason, we propose a high-sealing water pump bearing. Utility Model Content

[0004] The utility model aims to provide a high-sealing water pump bearing to solve the problems in the above background technology that the general water pump bearing has poor sealing performance and the water pump shaft easily slips with the bearing when rotating at high speed, thereby causing sealing failure.

The highly sealed water pump bearing has a waterproof plate on the outer ring of the bearing to seal the gap between the outer ring of the bearing and the inner ring of the bearing, and sealing strips are provided on the left and right sides of the waterproof plate to improve the sealing performance. Finally, small balls are provided to reduce the friction between the waterproof plate and the shaft sleeve, thereby preventing the waterproof plate from affecting the rotation of the bearing, so that the water pump bearing has good sealing performance and prevents impurities from entering the bearing.

[0018] 2. The highly sealed water pump bearing increases the friction between the shaft sleeve and the rotating shaft by providing anti-skid patterns inside the shaft sleeve, thereby preventing the rotating shaft and the shaft sleeve from slipping. An anti-skid ring is provided, and the anti-skid patterns are made of rubber material, so that the anti-skid ring has strong friction, thereby further increasing the friction between the shaft sleeve and the rotating shaft.
