Non-concentric elastic compensation sealing assembly

Abstract

The invention discloses a non-concentric elastic compensation sealing assembly. The non-concentric elastic compensation sealing assembly is characterized by comprising a rotary motion assembly and anaxial motion assembly, wherein the rotary motion assembly and the axial motion assembly sleeve a shaft, the axial motion assembly comprises a static sleeve fixedly installed with the shaft, the staticsleeve is provided with a movable sleeve capable of axially moving, and the movable sleeve is fixedly provided with a wear-resistant static ring; and the rotary motion assembly comprises an outer cover rotationally mounted on the shaft, a wear-resistant movable ring is fixedly arranged on the outer cover, and the wear-resistant static ring and the wear-resistant movable ring are matched and sealed. The static sleeve is provided with elastic teeth, and the static sleeve I penetrates through elastic tooth holes of the movable sleeve to be limited through the elastic teeth. The movable sleeve isinternally provided with an anti-rotation groove with a concave-convex structure, the wear-resistant static ring is provided with a wear-resistant static ring groove matched with the anti-rotation groove, the wear-resistant movable ring I is provided with a wear-resistant movable ring groove with a concave-convex structure, and the wear-resistant movable ring groove and an outer cover groove of the outer cover which has the corresponding convex-concave structure are matched and fixed.

Description

technical field [0001] This patented technology is applicable to the non-concentric elastic compensation sealing assembly on the idler rollers or drums of belt conveyors used in industries such as industrial mining, ports, wharves, grain, steel mills, etc., to prevent bearings from being affected by water or dust and reduce their service life. Background technique [0002] Idler rollers and drums are the key components to ensure the normal operation of the belt conveyor. The seals in the idler rollers and drums are the key components that affect their normal operation. The bearing in the drum fails, increases the load of the belt conveyor, or wears out the cylinder and causes the belt to wear out or tear and other major accidents. [0003] At present, the seal in the roller or drum mainly adopts non-contact labyrinth seal, and a small amount of contact seal is also used. Both of these two seals have certain shortcomings. The non-contact seal is generally waterproof but not ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem solved by this patent is that the non-contact sealing effect is not good, while the contact sealing is affected by the concentricity and the sealing and operation effect, and the sealing performance cannot be compensated after wear and tear, and the innovative design is carried out. The contact seal is not affected by the change of concentricity within a certain range. It can compensate and maintain the sealing pressure after wear and tear. The rotation resistance is small, and the non-concentric elastic compensation sealing assembly can be easily replaced and repaired.
