Driving Pulley

(1) The drum structure is advanced with reasonable parameters. The specialized computer program determines the axle diameter, the thickness of the drum body, the thickness of the end disc, The position of the circumferential welding seam ensures the least stress and the least number of cycles

(2) The pulley is divided into three kinds such as Light-duty, Medium -duty and Heavy-duty according to the carrying capacity,and the drum body of Light-duty and Medium-duty are welded with steel plate, the drum body of Heavy-duty is welded with cast iron plate .otherwise, Light-duty: the shaft and the wheel hub are connected by single key ; Medium-duty: the shaft and the wheel hub are connected by expansion sleeve ; Heavy duty: shaft and wheel hub is connecteed by expansion sleeve, There are one -side -out shaft and both-sides-out shaft.

(3) Modi Welding: gas tegimen welding et demergi arcum welding.

(4) The circumferential and longitudinal welding seam of the pulley body and the cast parts are detected by ultrasonic according to the requirements.

(5) In order to increase friction and prevent the conveyor belt from slipping, the surface of the driving pulley can be covered with herringbone rubber, diamond shape rubber and ceramic rubber.
