Description

Technical Field

[0001] The utility model relates to the field of bearing sealing rings, in particular to a bearing sealing ring for an automobile pulley. Background Art

[0002] Bearing is an important component in contemporary mechanical equipment. Its main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Automobile pulley bearings are important components of automobile drive systems, and cooperate with the power system of the automobile to complete the starting, acceleration, deceleration and other operations of the automobile. Automobile pulley bearings have very harsh working conditions and are often in high temperature and high-speed operation. At the same time, they are also in a high-dust environment, and are affected by axial, impact and radial centrifugal force and torsional torque of high-speed rotation. Therefore, the requirements for automobile pulley bearings are very strict. If the bearing is damaged and does not meet the requirements, it is likely to cause accidents and endanger lives. The existing bearing seals are not effectively fixed and are easy to fall off, affecting the use and bringing certain adverse effects to people's use process. For this reason, we propose an automobile pulley bearing seal. Utility Model Content
