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 belt pulley, and how is it used in mechanical systems?

A belt pulley is a mechanical device used in various systems to transmit power and motion between rotating shafts. It consists of a wheel with a grooved rim, known as the pulley, that is connected to a shaft. The pulley is typically made of materials such as cast iron, steel, or aluminum. It is used in conjunction with a belt or a rope to transfer rotational motion from one shaft to another. Here’s a detailed explanation:

A belt pulley is essential in mechanical systems for the following purposes:

  • Power Transmission: The primary function of a belt pulley is to transmit power between rotating shafts. It connects the driving shaft (input) to the driven shaft (output) through a belt or a rope. When the driving shaft rotates, the belt or rope engages with the grooves on the pulley, causing the pulley and the driven shaft to rotate. This allows power to be transferred from the driving shaft to the driven shaft, enabling the operation of various mechanical components or systems.
  • Speed Control: Belt pulleys are used to control the rotational speed of driven shafts. By varying the size or ratio of the pulleys connected by the belt, the rotational speed can be adjusted. Using different-sized pulleys, it is possible to increase or decrease the speed of the driven shaft compared to the driving shaft. This speed control capability is beneficial in applications where different rotational speeds are required for specific operations or to match the requirements of different components in a system.
  • Directional Change: Belt pulleys also enable the change of direction in mechanical systems. By arranging multiple pulleys with belts or ropes in a system, the rotational motion can be redirected. For example, a system with two pulleys connected by a belt can change the direction of the driven shaft compared to the driving shaft. This directional change allows for the transmission of power and motion in desired orientations, enabling the operation of mechanical components or systems in different directions.
  • Tension Control: Belt pulleys play a role in maintaining proper tension in belt-driven systems. The tension in the belt is important to ensure a secure and reliable connection between the pulleys. Pulleys with adjustable features, such as tensioning systems or idler pulleys, help maintain the optimal tension in the belt. Proper tension control prevents belt slippage, ensures efficient power transmission, and reduces wear on the belt and pulley surfaces.
  • Noise and Vibration Reduction: Belt pulleys contribute to noise and vibration reduction in mechanical systems. The design of the pulley, including the groove profile and surface finish, can help minimize noise and vibration generated during operation. Additionally, proper alignment and tensioning of the belt ensure smoother engagement with the pulley, reducing noise and vibration levels. This is particularly important in applications that require quiet operation or where excessive vibrations can affect system performance or operator comfort.
  • Compatibility and Interchangeability: Belt pulleys offer compatibility and interchangeability benefits in mechanical systems. They provide a flexible and modular approach to power transmission, allowing different pulleys to be easily interchanged or replaced based on specific requirements. This versatility enables system designers and operators to adapt and modify mechanical systems more efficiently, making it easier to accommodate changes in load, speed, or other operational parameters.

In summary, a belt pulley is a mechanical device used for power transmission and motion control in various mechanical systems. It connects rotating shafts through belts or ropes, allowing power to be transmitted from one shaft to another. Belt pulleys provide speed control, directional change, tension control, noise and vibration reduction, as well as compatibility and interchangeability benefits. By utilizing belt pulleys, mechanical systems can efficiently transfer power, control speeds, and enable the operation of different components or systems in desired directions.
