Ultrahigh molecular weight polyethylene roller

Abstract

The invention discloses a novel roller formed by assembling an ultrahigh molecular weight polyethylene tube, a metal bearing, a metal shaft and a plastic end cover. The roller has the properties of in-adhesion and material accumulation, flexible and stable operation, long service life, extension of belt service life, low operating cost, remarkable economic benefit, operating noise reduction, good bearing performance and corrosion resistance and the like, can be widely used in industries of metallurgy mine, coal mine, chemical engineering, grain storage, building material, port, salt field, electric power and the like, and is a good substitute for a metal roller.

Description

technical field [0001] The invention relates to an industrial idler, in particular to an ultra-high molecular weight polyethylene idler. Background technique [0002] At present, the main rollers used in the market are made of steel structure, which is complex in structure and not easy to maintain. Water, coal slime, cinder, ore, stones, etc. often enter the bearing, which makes the bearing movement gap smaller or rusty, resulting in poor operation. Flexible, or even stuck, aggravated the wear of the idler roller and the belt. The general service life is only 3 months. The daily maintenance of the belt conveyor is mainly to replace the idler roller. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of steel rollers and provide a new ultra-high molecular weight polyethylene roller with low cost, high transport capacity, belt protection, low wear, energy saving and consumption reduction. [0004] The process of the pres...
