Roller housing

Abstract

The invention discloses a bearing seat of a carrier roller. The bearing seat of the carrier roller comprises an inner cylinder body and an outer cylinder body, wherein the inner cylinder body and the outer cylinder body are coaxially arranged, a reinforced rib is arranged between one end of the inner cylinder body and the inner wall of the outer cylinder body, a bearing installation groove is formed between an end portion inner ring of the outer cylinder body and the reinforced rib, a groove is formed in an outer ring of the outer cylinder body in the axial direction, a stopping ring is arranged at the other end of the inner cylinder body, the inner diameter of the stopping ring is smaller than that of the inner cylinder body, and a supporting rib is arranged in the inner wall of the stopping ring in the radial direction. The inner cylinder body, the outer cylinder body, the reinforced rib, the stopping ring and the supporting rib are formed by injection of materials such as high molecular weight polyethylene, plastics or nylon. The bearing seat of the carrier roller has the advantages of being reasonable in design, simple in structure, easy to machine, convenient to install, low in cost, strong in stability of the size, high in shock resistance, strong in practicability and easy to popularize and apply.

Description

technical field [0001] The invention relates to an idler roller used for supporting belt transportation, in particular to an idler roller bearing housing. Background technique [0002] The bearing housings of traditional rollers are mostly made of metal materials, which are heavy in weight, high in cost, low in wear resistance and fatigue resistance, and poor in vibration reduction, sound absorption, self-lubrication, insulation and self-extinguishing properties. At present, there are also idler bearing housings made of plastic, but they are not easy to popularize and apply due to complex structure, cumbersome manufacturing process, high cost and short service life. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides an idler bearing seat with simple structure, low cost and long service life. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following techn...
