Integral abrasion resistant anti-ageing comb-shaped carrier roller for belt conveyer

Abstract

The invention discloses an integral abrasion resistant anti-ageing comb-shaped carrier roller for a belt conveyer. The integral abrasion resistant anti-ageing comb-shaped carrier roller comprises a carrier roller shaft, a carrier roller cylinder and an outer ring, wherein bearings are mounted at the two ends of the carrier roller shaft; the bearings are wrapped with the carrier roller cylinder; the carrier roller cylinder rotates around the carrier roller shaft; the outer ring fixed outside the carrier roller cylinder is an integral rubber comb-shaped ring; sealing parts are arranged outside the bearings; crests of comb-shaped ripples of the integral rubber comb-shaped ring are circular horns; cross sections of the ripples are isosceles triangles; a plurality of groups of comb-shaped ripples are formed on the integral rubber comb-shaped ring; and each group has 2 to 5 ripples. According to the integral abrasion resistant anti-ageing comb-shaped carrier roller for the belt conveyer, the carrier roller shaft, the bearings, the sealing parts, the carrier roller cylinder and the integral rubber comb-shaped ring are manufactured or purchased according to size and precision requirements, and then, all the parts are assembled into the integral abrasion resistant anti-ageing comb-shaped carrier roller for the belt conveyer; the outer layer is an integral structure, so that the defect that once one external part is damaged, the other external parts are damaged is avoided; and the structure is reasonable, the stress is uniform, a belt is not damaged, the sealing performance is good, the integral abrasion resistant anti-ageing comb-shaped carrier roller is abrasion resistant, corrosion resistant and anti-ageing, the service life is long, the cost is low, and the changing and utilization are convenient.

Description

technical field [0001] The invention relates to an accessory of a belt conveyor, which is an integral wear-resistant and anti-aging belt conveyor comb-shaped idler. Background technique [0002] For some open-pit mines or large-scale industrial and mining enterprises, the transportation of production materials is completed by belt conveyors, which are referred to as belt conveyors. This kind of tape machine is generally relatively long, some tens of meters or even tens of kilometers. Due to the weight of the tape itself, the tape running between the first wheel and the tail wheel will have a large deflection no matter the upper side or the lower side. , that is, the belt surface is concave. In order to run smoothly, the belt surface must be supported to a certain extent. The supporting part is the idler roller. The role of the upper idler is mainly to carry the weight of the material and provide rolling contact for the belt to reduce friction. The contact surface between t...

AI Technical Summary

Problems solved by technology

[0004] Judging from the situation of the replaced idler roller, the damage of the idler roller is mostly caused by the damage of the bearing, rubber ring and spacer sleeve.

[0005] Due to the large dust on the peeling belt and the harsh weather, the sealing performance of the comb roller and the bearing is poor, and dust and rainwater are easy to enter, which reduces the lubricity and rotation of the bearing, thereby reducing the service life of the bearing and damaging the bearing.

[0006] Due to the fast running speed and large load capacity of the stripping system tape machine, the frictional resistance is extremely high, and most of the aprons used now are made of recycled rubber, which not only has poor wear resistance, but also has poor elasticity, aging resistance and corrosion resistance. , under the interaction of the fast running of the tape machine and dust, rain, etc., the apron with poor quality is easy to wear or break directly

[0007] Due to the relatively large friction and vibration on the belt conveyor, and the poor wear resistance of the isolation sleeve, the material is relatively brittle. When the apron on the roller is severely worn and broken, the isolation sleeve cannot be fixed, and the entire idler will lose its normal function. function, but also easy to scratch the tape, speeding up its scrapping
