Product Description
CHINA LEADING FACTORY OF BELT CONVEYOR
CONVEYOR PULLEY WORKSHOP SHOW
CONVEYOR PULLEY - BRIEF INTRODUCTION
Our company has adopted proprietary technology and equipment imported from German PWH company for the design and manufacturing of various pulleys . As a key component of the belt conveyor, the pulley should have high reliability. Our company's R&D center has improved the pulley structure, reduced structural stress, and increased the lifespan and reliability of the pulley group through finite element analysis and optimization calculations. Our company's pulley is manufactured from specialized high-end manufacturing equipment and has achieved serialized and large-scale production.
We have produced conveyor pulleys for belt width up to 2.4 m, pulley diameter up to 1.8 m, and maximum tension up to 300 tons.

CONVEYOR PULLEY - PROCESS FLOW
CONVEYOR PULLEY - PRODUCT FEATURES
For pulleys with complex forces, large loads and used in heavy working conditions, 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 calculation program to determine the shaft diameter, cylinder skin thickness, wheel amplitude plate shape and spacing, as well as the position of the 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 years and the technical difficulties of manufacturing and installing axial double keyways, but also achieves overall quenching and eliminates welding internal stress.
(4) The circumferential and longitudinal welds of the pulley have undergone non-destructive testing, and the casting quality of the wheel hub has undergone magnetic particle or ultrasonic testing.
(5) The total radial runout of the outer circle after roller casting is less than 1mm.
(6) All drums undergo static balance tests before leaving the factory to achieve G40 accuracy.
(7) All driving pulley and directional pulley with high stress have undergone finite element analysis to ensure that the stress and strain of the rollers meet the requirements.
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 fatigue fracture at the welding seam of the existing pulley plate in China. The pullley (including the welding part) is guaranteed to have a rotational fatigue strength of over 108°.
