A reducer and sealing mechanism thereof

Abstract

The present invention relates to the technical field of reducers, and in particular to a reducer and a sealing mechanism thereof. The reducer comprises a rotating shaft and a body, and the rotating shaft and the body are sealed by the reducer sealing mechanism; the reducer sealing mechanism comprises a seal, an intermediate ring, an adjustment component, and two coil springs, all of which are inserted into the body, and the seal is used to seal the rotating shaft and the body when the vehicle is parked; the intermediate ring is sleeved on the rotating shaft and can slide along the axial direction of the rotating shaft; the coil spring is sleeved on the rotating shaft, and the two coil springs are respectively arranged on both sides of the intermediate ring, and the two ends of the coil spring are respectively arranged on the intermediate ring and the rotating shaft, and the spiral directions of the two coil springs are opposite, and both are used for spirally sealing the rotating shaft and the body; the adjustment component is configured to be able to adjust the moving direction of the intermediate ring according to the direction of the rotating shaft, and then when the rotating shaft rotates, the intermediate ring moves to the side of the coil spring opposite to the direction of the rotating shaft, so that it can automatically adapt to different directions of the rotating shaft and improve applicability.
