Seal carrier roller

Abstract

The invention relates to a seal carrier roller, comprising a roller body and a central shaft, wherein the roller body is made from an ultra-high molecular weight polyethylene material, inner rings of two ends of the roller body are respectively provided with a bearing block, a bearing is arranged between a central shaft and each of two bearing blocks, the outer sides of the two bearings are respectively provided with a set of seal devices arranged between the roller body and the central shaft. The seal carrier roller disclosed by the invention has a reasonable design and a simple structure and provides an ultra-high molecular weight polyethylene Japanese type seal carrier roller for a material conveyor; in addition, the seal carrier roller has the advantages of low raw material consumption, low cost, simple and convenient manufacturing process, abrasion resistance, high rotation speed, low resistance, self lubricity, shock strength, fire resistance, inadhesion, excellent resistances to static electricity, aging, corrosion and the like, and does not generate waste water, waste gas and waste materials during production and use so as to belong to energy-saving environment-friendly products.

Description

technical field [0001] The invention relates to an idler roller used on a material conveyor, in particular to a sealed idler roller. Background technique [0002] At present, in the mining industry, chemical industry, coking, steel, thermal power, coal washing, grain processing, sugar industry, salt, cement, lime, sand, glass, metallurgy, fertilizer transportation, coking coal supply, port terminals and other industries, domestic support Most of the rollers are still made of steel rollers, which are bulky, have high energy consumption, large starting torque, and are not resistant to corrosion. Under the combined action of corrosion and wear, the service life is short. In addition, the central shaft of the roller generally adopts steel rolling bearings, which need to be lubricated regularly, and due to the poor sealing effect, it is not suitable for working in humid, dusty, and corrosive environments, which seriously affects the normal operation and conveying efficiency of th...

[0002] At present, in mining industry, chemical industry, coking, steel, thermal power, coal washing, grain processing, sugar industry, salt, cement, lime, sand, glass, metallurgy, fertilizer transportation, coking coal supply, port and wharf and other industries, domestic support Most of the rollers still use steel rollers, which are bulky, high energy consumption, large starting torque, and not resistant to corrosion. Under the combined action of corrosion and wear, the service life is short

In addition, the central shaft of the roller generally adopts steel rolling bearings, which need to be lubricated regularly, and due to the poor sealing effect, it is not suitable for working in humid, dusty, and corrosive environments, which seriously affects the normal operation and conveying efficiency of the conveyor.
