PROCESS FLOW OF PULLEY

Our company is equipped with necessary equipment for processing pulleys, such as large oil pressure machines, rolling machines, specialized puley automatic explosive welding operators,large diameter lathes, boring machines,ulrasonic faw detectors, static balancing devices, pressure casting machines, etc, Due to the special correcton process adopted by the company the puley pipe skin is rounded before processing, and the pulley pipe wall is uniform after processing, thereby ensuring that the puley has high static balance performance and high mechanical

 

PRODUCT FEATURES

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°
