Conveyor pulleys, produced by JSC PTM have a reliable design, ensuring their uninterrupted operation during the entire period of operation.
Drive pulleys are designed to transfer the tractive effort required to drive the conveyor belt. The rotation of the pulley is carried out with the use of a gearbox or a gear motor.
Non-driven pulley are divided into head, tail (end), tension, reverse, deflecting, bypass, clamping.
This type of pulley is used in tensioning stations, bending places of a conveyor belt, as a dumping barrel, etc.
Pulley are available in both smooth and lined (rubberized) performance. The drive pulley can be manufactured with two shaft consoles for connection with two drive mechanisms located symmetrically relative to the axis of the conveyor.
They represent a welded structure consisting of a rolled shell, two discs with hubs, mounted on the shaft by means of a keyed joint.
A design feature of such pulley is the fixation of the shaft (2) in the discs (3) using a clamping coupling (4).
The rotation of the barrel is carried out using the drive
