[0002] Bearings are an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. At present, bearings are used in mechanical equipment for rotating loads. Although general bearings can carry loads in rotation, some mechanical equipment has a poor external environment, and mud often invades the bearings, which can easily lead to problems such as poor lubrication and early peeling of the balls in the bearings.
[0003] At present, in order to prevent impurities such as mud from entering the inside of the bearing, a mud retaining ring is arranged between the outer bearing and the inner bearing to block the mud. However, most traditional mud retaining rings are sleeved on the bearing, and the mud retaining rings often fall off due to shaking and other reasons, affecting the mud retaining effect. The mud retaining ring may also enter the inside of the bearing, affecting the normal rotation of the ball in the bearing and causing damage to the bearing. For this reason, the present application proposes a bearing with a mud retaining structure to solve this problem.
