Drive/Head Pulley – A conveyor pulley used for the purpose of driving a conveyor belt. Typically mounted in external bearings and driven by an external drive source.
Return/Tail Pulley – A conveyor pulley used for the purpose of redirecting a conveyor belt back to the drive pulley. Tail pulleys can utilize internal bearings or can be mounted in external bearings and are typically located at the end of the conveyor bed. Tail pulleys commonly serve the purpose of a Take-Up pulley on conveyors of shorter lengths.
Snub Pulley – A conveyor pulley used to increase belt wrap around a drive pulley, typically for the purpose of improving traction.
Take-Up Pulley – A conveyor pulley used to remove slack and provide tension to a conveyor belt. Take-Up pulleys are more common to conveyors of longer lengths.
Bend Pulley – A conveyor pulley used to redirect the belt and provide belt tension where bends occur in the conveyor system.

The specification of pulley:
Drive Drum: is the main component of power transmission. The drum can be divided into single drum (the angle of the belt to the drum is 210 ° ~ 230 °) , Double Drum (the angle of the belt to the drum is up to 350 °) and
multi-drum (used for high power) . 
Bend Drum: is used for changing the running direction of the conveyor belt or increasing the surrounding angle of the conveyor belt on the driving roller, and the roller adopts a smooth rubber surface . The drum shaft shall be forgings and shall be nondestructive tested and the inspection report shall be provided. 
The Various Surface of Pulley:
Conveyor pulley lagging is essential to improve conveyor belt performance, the combination of our pulley lagging can reduces belt slippage, improve tracking and extends life of belt, bearing & other components.

PLAIN LAGGING:This style of finish is suitable for any pulley in the conveyor system where watershed is not necessary. It provides additional protection against belt wear, therefore, increasing the life of the pulley.
DIAMOND GROOVE LAGGING:This is the standard pattern on all Specdrum lagged conveyor pulleys. It is primarily used for reversing conveyor drive pulleys. It is also often used to allow bi-directional pulley rotation, and the pattern allows water to be dispersed away from the belt.
HERRINGBONE LAGGING:The herringbone pattern’s grooves are in the direction of rotation, and offers superior tractive properties. Each groove allows water and other liquids to escape between the face of the drum pulley and the belt. Herringbone grooved pulleys are directional and should be applied to the conveyor in a manner in which the grooves point toward the direction of the belt travel.
CHEVRON LAGGING:Some customers specify that the points of the groove should meet – as done in Chevron styled lagging. As before with the herringbone style, this would be used on drive drum pulleys and should be fitted in the correct manner, so as to allow proper use of the pattern and water dispersion also.
CERAMIC LAGGING:The Ceramic tiles are moulded into the lagging which is then cold bonded to the drum pulley. This style of finish allows excellent traction and reduces slippage, meaning that the belt tension is lower and, therefore as a result, increases the life of the pulley.
WELD-ON STRIP LAGGING: Weld-On Strip Lagging can be applied to bi-directional pulleys, and also has a finish to allow the easy dispersion of water or any fluids between the drum pulley and the belt.

 

The Components of Pulley:

1. 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.
2.Diaphragm Plates: The diaphragm or end plates of a pulley are circular discs which are fabricated from thick steel plate and which are welded into the shell at each end, to strengthen the drum.The end plates are bored in their centre to accommodate the pulley Shaft and the hubs for the pulley locking elements.
3.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 elements. The shaft and hence pulley shafts are often stepped.
4.Locking Elements:These are high-precision manufactured items which are fitted over the shaft and into the pulley hubs. The locking elements attach the pulley firmly to the shaft via the end plates.
5.Hubs:The hubs are fabricated and machined housings which are welded into the end plates.
6.LaggingIt is sometimes necessary or desirable to improve the friction between the conveyor belt and the pulley in order to improve the torque that can be transmitted through a drive pulley. Improved traction over a pulley also assists with the training of the belt. In such cases pulley drum surfaces are `lagged` or covered in a rubberized material.
7.Bearing: Bearings used for conveyor pulleys are generally spherical roller bearings, chosen for their radial and axial load supporting characteristics. The bearings are self-aligning relative to their raceways, which means that the bearings can be ‘misaligned’ relative to the shaft and plummer blocks, to a certain degree. In practical terms this implies that the bending of the shaft under loaded conditions as well as minor misalignment of the pulley support structure, can be accommodated by the bearing.

What is a heavy-duty pulley, and how is it different from standard pulleys?

A heavy-duty pulley is a specialized type of pulley designed to handle heavier loads and withstand more demanding conditions compared to standard pulleys. It is specifically engineered to provide enhanced strength, durability, and load-bearing capacity. Here is a detailed explanation of what sets a heavy-duty pulley apart from standard pulleys:

  1. Construction and Materials: Heavy-duty pulleys are constructed using high-strength materials such as steel or cast iron, which offer superior durability and load-bearing capabilities. These materials provide the necessary strength and resistance to withstand heavy loads, intense forces, and prolonged use. In contrast, standard pulleys are often made from lighter materials such as aluminum or plastic, which are suitable for lighter loads and less demanding applications.
  2. Load-Bearing Capacity: Heavy-duty pulleys are designed to handle significantly higher loads compared to standard pulleys. They typically have larger sheaves and bearings, allowing them to support and distribute the weight of heavy loads more effectively. The increased load-bearing capacity of heavy-duty pulleys enables them to handle heavy machinery, industrial equipment, and other applications that involve substantial weight.
  3. Reinforced Structure: Heavy-duty pulleys feature a reinforced structure to withstand the forces and stresses associated with heavy loads. They may have thicker walls, additional bracing, or reinforced hubs to enhance their structural integrity. These design features ensure that heavy-duty pulleys can endure the higher forces and resist deformation or failure under heavy load conditions.
  4. Resistance to Wear and Corrosion: Heavy-duty pulleys are often equipped with protective coatings, such as powder coating or zinc plating, to enhance their resistance to wear, abrasion, and corrosion. These coatings provide an extra layer of protection against the harsh operating environments commonly encountered in heavy-duty applications, such as industrial settings or outdoor environments. Standard pulleys may not have the same level of protection, making them more susceptible to wear and corrosion over time.
  5. Specialized Features: Heavy-duty pulleys may incorporate additional features to optimize their performance in demanding applications. These features can include sealed bearings for improved protection against contaminants, precision machining for smoother operation, or specialized design elements for specific industries or applications. Standard pulleys, on the other hand, are typically designed for general-purpose use and may lack these specialized features.

In summary, a heavy-duty pulley is designed to handle heavier loads, endure more demanding conditions, and provide enhanced strength and durability compared to standard pulleys. With their robust construction, increased load-bearing capacity, reinforced structure, resistance to wear and corrosion, and specialized features, heavy-duty pulleys are specifically engineered to meet the requirements of challenging applications in various industries.
