Heavy Duty Steel Gravity Conveyor Belt Trough Idler Rollers Set Carrying Roller Conveyor Parts for Construction Machinery

Product Description

Product Description

Idler rollers, or sometimes simply known as conveyor rollers, are cylindrical-shaped bars that run along and underneath a conveyor belt. There are many different types of idler rollers with varying functions.

Usually, idler rollers aid in the supporting of weight and impact of the materials being transported along the belt. They also assist in the smooth, continuous movement of the material along the belt.

Idler rollers can be self-aligning and assist in maintaining the belt tracking. Depending on the structure and shape of the conveyor belt, the rollers are usually positioned within a metal frame and are known as idler sets.

Feature 1) for the viscous material transportation 2) cleaning 3) prevent the belt running deviation

 For pulleys with complex forces, arge loads and used in heavy working conditons, they all adopt a cast welded structure and
expansion sleeve connection, Compared with traditional drums in China, this type of drum mainly has the following characteristics:
(1) The structural parameters of the pulley are advanced and reasonable, and there is a dedicated computer calculaion program to
determine the shaft diameter, cylinder skin thickness, wheel ampltude plate shape and spacing, as well as the position ofthe
circumferential weld seam set at the position where the stress is minimum and the number of cycles is minimum.
(2) The key technology of using single sided welding and double sided forming ensures the quality of the weld seam.
(3) The expansion sleeve connection is used between the drum hub and shaft, which not only solves the problem of key connection
stress concentration that has been existing for many vears and the technical dificulties of manufacturing and instaling axial
double keyways, but also achieves overal auenching and eiminates weding interna stress

Due to a series of measures taken, the pulley group produced by sK has a reasonable structure, large bearing capacity, and
reliable performance. And it overcomes the problem of faigue fracture at the welding seam ofthe existing puley plate in china, The
pulley lincuding the welding part is guaranteed to have a rotational fatigue strength of over 108°
