Abstract

The invention discloses a roller carrier shaft end sealing ring good in weather ability. The roller carrier shaft end sealing ring comprises a bearing pedestal, a sealing bearing, a mounting seat, a gasket, an inner barrel, an outer barrel, an inner sealing cover and an outer sealing cover, all of which are sequentially arranged on a shaft in a sleeving manner from inside to outside relative to the center point of the shaft. A sealing cavity is formed in the bearing pedestal. The mounting seat is arranged in the sealing cavity. The gasket is mounted on the side, away from the bearing pedestal,of the mounting seat. Multiple annular second inserting grooves are arranged on the side, close to the outer barrel, of the inner barrel. Multiple annular fourth inserting feet are arranged on the side, close to the inner barrel, of the outer barrel. The fourth inserting feet are located in the second inserting grooves. Multiple second sealing protrusions are arranged on the inner wall of each second inserting groove. The side, away from the inner barrel, of the outer barrel is sleeved and connected with a cold plate. The roller carrier shaft end sealing ring has excellent weather ability.

Description

technical field [0001] The invention relates to the technical field of sealing rings, in particular to an idler shaft end sealing ring with good weather resistance. Background technique [0002] The idler roller is an important part of the belt conveyor. It has many types and large quantities, and can support the weight of the conveyor belt and materials. It accounts for 35% of the total cost of a belt conveyor and produces more than 70% of the resistance, so the quality of the idler is particularly important. In the prior art, the sealing sleeve used to seal the end of the idler roller shaft will affect its waterproof performance and stability during use due to the influence of the use environment. [0003] After searching, the Chinese patent application number is 201110145102.9, which discloses a sealing device for idler rollers. A set of bearings, bearing seats, lower seals, upper seals, The end face sealing device composed of the sealing top cover and the shaft card, t...
