Product Description

We offer a variety of conveyor pulleys to meet the diverse needs of our clients. Our pulleys come in Drive Pulley, Bend Pulley, Snub Pulley, and Take-Up Pulley types, with lengths ranging from 200mm to 2500mm. Our materials include carbon steel, stainless steel, and rubber, and our pulleys can be surface treated with smooth, grooved, herringbone, and ceramic lagging. We use submerged arc welding to ensure the highest level of quality and durability. Our bearings are from well-known brands, and our pulleys’ structures consist of a tube, shaft, self-aligning bearing, bearing seat/house, hub, locking bushing, and end disc.

Drive Pulley Introduction

The Drive Pulley is located at the conveyor’s discharge terminus, providing the driving force for the system. It typically has a larger diameter than other pulleys to increase its life and traction. We can supply Drive Pulleys with hot vulcanized rubber lagging, plain or grooved, with different patterns of grooving such as herringbone or CHINAMFG to increase tractive friction under dirty or wet conditions. CHINAMFG grooves can be installed in any orientation, regardless of belt direction.

The Components of a Pulley Drum Include:

Drum or Shell The drum is the portion of the pulley in direct contact with the belt. The shell is fabricated from either a rolled sheet of steel or from hollow steel tubing. The shell has a specific “face” width and diameter determined by the belt width and type and rating of the belt to be used on the conveyor.
Diaphragm Plates The diaphragm or end plates of a pulley are circular discs fabricated from thick steel plate and welded into the shell at each end to strengthen the drum. The end plates are bored in their center to accommodate the pulley shaft and the hubs for the pulley locking elements.
Shaft The shaft is designed to accommodate all the applied forces from the belt and/or the drive unit with minimum deflection. The shaft is located and locked to the hubs of the end discs by means of a locking element. The shaft is supported on both ends by bearings which are housed in plummer blocks to support the shaft and pulley assembly on the conveyor structure. Pulley shafts are often stepped due to bending moments and deflection limitations.
Locking Elements These are high-precision manufactured items fitted over the shaft and into the pulley hubs. The locking elements attach the pulley firmly to the shaft via the end plates. Locking elements work on the friction-grip principle whereby the element is able to be fastened to the shaft and hub simultaneously and concentrically by tightening a series of screws around the locking element.
Hubs The hubs are fabricated and machined housings welded into the end plates, sized according to the size of the pulley and the diameter of the shaft and the locking element required for the specific duty.
Lagging It is sometimes necessary or desirable to improve the friction between the conveyor belt and the pulley to improve the torque that can be transmitted through a drive pulley. In such cases, pulley drum surfaces are “lagged” or covered in a rubberized material. This cover is usually 8mm to 12mm thick and can be plain or have a grooved pattern. The rubber lagging is vulcanized to the pulley shell to ensure that it remains attached under adverse operating conditions.
Bearing Assemblies Bearings support the rotating shaft and, hence, the pulley. The bearings are housed in “plummer blocks” which enable the mass of the pulley assembly plus the belt tension forces to be transmitted to the pulley supporting structure. Plummer blocks are often bolted to “sole plates” welded to the structure. The sole plates incorporate jacking screws to enable the pulley to be aligned correctly and relatively easily.

Our company also supplies various other industrial products, such as agricultural gearboxes, power output shafts, sprockets, fluid couplings, worm gear reducers, gears and racks, roller chains, pulleys and pulleys, planetary gearboxes, timing pulleys, bushings, and more.
