a pulley, the deflection of the shaft causes bending mo-ment being applied to the shaft connection and the end disc. The significance of the bending moment is depen-dent on the pulley geometry, as shown in Fig. 2. As belts advanced, they became stronger and more flexible. This resulted in the pulley diameter shrinking, while the shaft diameter ...

Conveyor Systems are mechanical devices or assemblies that transport material with minimal effort. While there are many different kinds of conveyor systems, they usually consist of a frame that supports either rollers, wheels, or a belt, upon which materials move from one place to another. They may be powered by a motor, by gravity, or …

The cause for failures of shafts in a conveyor pulley in iron-making unit at JSW Steel has been investigated. Visual, metallographic, chemical, and fractographic studies were carried out in this study. Fracture studies of the shaft revealed shear failure because of overload. Detailed investigation revealed that the source of overload and …
The majority of nondrive conveyor pulleys use rotating shafts, and typi-cal idler rolls use nonrotating shafts, even though both products are used to support and guide the …
Torque input to shaft by each drive assembly (equal with torque generated by belt tension) = (BT1 – BT2)/2 x Pulley Diameter /2 = 52,341 N.m. Pulley mass = 5,286 Kg.
pulley shaft bearing and the low-speed coupling. With the backstop mounted on the reducer, if a failure occurred in the low-speed coupling, the conveyor would run back since the backstop would not be connected to the pulley shaft. Backstop Size Selection The vast majority of recognized engineering firms, both in the US and abroad, use the breakdown

Replacement lagging will ensure the pulley shell is protected and the conveyor belt traction is maintained. The rate of wear on the lagging depends on the lagging material. Pulley re-lagging involves removing the old lagging material and replacing it with a new layer. DYNA Engineering has a full range of re-lagging options which includes hot ...
Never lift the pulley using the bearing housing. Lifting hardware on the bearing is not designed to support the pulley assembly weight. Place weight rated nylon lifting straps around the pulley shaft between the pulley face and bearings. Place the straps as close to the pulley face as possible. Never use a chain to move a conveyor pulley assembly.
