Carrier roller

Abstract

A carrier roller comprises a carrier roller tube, a bearing chamber, a baffle cover and a carrier roller shaft; an outer edge of the bearing chamber is connected with an inner wall of the carrier roller tube, and is extended out of the carrier roller tube; a bearing is arranged in an inner hole of the bearing chamber, a sealing ring is arranged outside the bearing, the baffle cover is arranged outside the sealing ring, an outer diameter of the baffle cover is corresponding to the outer diameter of the outer edge of the bearing chamber; a bulge is arranged in the middle part of the baffle cover, a size of the bulge is corresponding to that of the inner hole of the bearing chamber; the bulge is inserted into the inner hole of the bearing chamber to tightly lean against the outer side of the sealing ring; the baffle cover, the bearing chamber and the carrier roller tube are fixedly and integrally connected; the sealing ring adopts a polyurethane axial four-layer lip-type sealing ring; and the baffle cover, the bearing chamber and the carrier roller tube are in welded connection. The carrier roller makes the outer diameter of the baffle cover and the outer diameter of the outer edge of the bearing chamber be consistent, and fixedly and integrally connects the baffle cover, the bearing chamber and the carrier roller tube, thus sealing effect of the carrier roller is improved, overall strength of the carrier roller is increased, and service life of the carrier roller is prolonged.

Description

technical field [0001] The invention relates to the technical field of conveyors, in particular to an idler roller. Background technique [0002] At present, the dust-proof effect of the rollers used on the belt conveyor is good, but the waterproof effect is generally poor, because the cover is squeezed on the hole wall of the bearing chamber, the sealing performance and connection strength are very poor, but the actual performance of most rollers The working environment is often exposed to water, especially some rollers are used for underground operations, and it is easier for water to infiltrate from the cover, causing corrosion and damage to the bearing, resulting in the failure of the normal use of the roller; and the cover structure of the traditional roller makes it in It is easy to loosen during transportation, reducing the matching effect with the bearing chamber. When the parts on the idler roller are damaged, it is difficult to disassemble, repair and replace, and ...

[0002] At present, the dust-proof effect of the rollers used on the belt conveyor is good, but the waterproof effect is generally poor, because the cover is squeezed on the hole wall of the bearing chamber, the sealing performance and connection strength are very poor, but the actual performance of most rollers The working environment is often exposed to water, especially some rollers are used for underground operations, and it is easier for water to infiltrate from the cover, causing corrosion and damage to the bearing, resulting in the failure of the normal use of the roller; and the cover structure of the traditional roller makes it in It is easy to loosen during transportation, reducing the matching effect with the bearing chamber. When the parts on the idler roller are damaged, it is difficult to disassemble, repair and replace, and usually requires special equipment to solve the problem.
