Carrier roller with high sealing performance

Abstract

The invention discloses a high-sealing-performance carrier roller which comprises a roller body, bearing seats are symmetrically arranged at the two ends of the roller body, a bearing is fixedly arranged in each bearing seat, a roller shaft penetrating through the roller body is arranged between the two bearings, a bottom sealing ring is arranged on the roller shaft and located on one side of the bearings, and an inner sealing ring is arranged on the roller shaft and located on the other side of the bearings. According to the carrier roller, the gap between the bearing seat and the roller shaft is sealed through the bottom sealing ring, so that oil dirt in the bearing or external dirt can be prevented from entering the roller body, and in addition, the roller body is not prone to falling off, so that the service life of the carrier roller is prolonged, and the service life of the carrier roller is prolonged. And the inner sealing ring and the outer sealing ring are arranged on the other side of the bearing, so that external pollutants can be prevented from entering the bearing to influence the service life of the bearing, meanwhile, the external pollutants are further prevented from entering the roller body, and the sealing of the roller body is enhanced.

Description

technical field [0001] The invention relates to the technical field of belt conveyors, in particular to a high-sealing idler. Background technique [0002] As a universal continuous conveying equipment, belt conveyors are widely used in mining, wharf, electric power, coal, chemical and other industries, and have many advantages such as high efficiency and environmental protection. As the key component of the belt conveyor, the use of the idler is larger, and its performance greatly affects the operation effect of the whole machine. Especially in the open air, underground, high pollution environment, etc., its early damage is caused by poor sealing. The phenomenon is not uncommon. Most of the idler types widely used in the existing industry are labyrinth seal structure types. Although they have the advantages of low rotational resistance, their protective performance is not enough to meet the requirements of high pollution environments. Conventional contact seal type idlers ...

Problems solved by technology

As the key component of the belt conveyor, the idler roller is used in a large amount, and its performance greatly affects the operation effect of the whole machine, especially in the open air, underground, and high-pollution environments, and its early damage is caused by poor sealing. The phenomenon is not uncommon. Most of the idlers widely used in the industry are labyrinth seal structures. Although they have the advantage of small rotation resistance, their protection performance is not enough to meet the requirements of high pollution environments; while the conventional contact seal type idlers The sealing ring used has a large resistance, which affects the power consumption of the equipment and increases the wear of the moving parts.
