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.

How do different types of belts and pulleys impact system performance?

The performance of a system using belts and pulleys can be influenced by the choice of different types of belts and pulleys. Here's a detailed explanation of how different types of belts and pulleys can impact system performance:

Belts:

  • Timing Belts: Timing belts have teeth on the inner side, which mesh with corresponding grooves on the pulleys. They are commonly used in applications requiring precise synchronization of rotational motion, such as in engines or machinery with strict timing requirements. Timing belts offer excellent power transmission accuracy and are less prone to slipping, ensuring precise motion control and minimizing timing errors.
  • V-Belts: V-belts are trapezoidal in shape and typically used in applications where high torque transmission is required. They rely on the wedging action between the belt and the pulley to transmit power. V-belts are known for their high grip and efficient power transfer capabilities. They are commonly used in automotive engines, industrial machinery, and HVAC systems.
  • Flat Belts: Flat belts are flat in shape and provide a larger contact area with the pulleys. They are versatile and can be used in a wide range of applications. Flat belts are commonly used in conveyor systems, agricultural machinery, and industrial equipment. They offer flexibility, ease of installation, and high power transmission efficiency.
  • Ribbed Belts: Ribbed belts, also known as serpentine belts, have a series of ribs on the inner side. These ribs engage with corresponding grooves on the pulleys, allowing for efficient power transmission. Ribbed belts are commonly used in automotive engines, where they drive multiple accessories such as alternators, power steering pumps, and air conditioning compressors. They offer high power transmission capacity and reduced slippage.
  • Round Belts: Round belts are circular in cross-section and typically made of elastic materials. They are commonly used in applications requiring flexibility and high-speed power transmission, such as in office machinery, printers, and small appliances. Round belts offer ease of installation, quiet operation, and good shock absorption capabilities.

Pulleys:

  • Fixed Pulleys: Fixed pulleys have a fixed position on the shaft and do not change the direction or speed of the input motion. They are commonly used to redirect the path of the belt or to provide tension in the system.
  • Variable Speed Pulleys: Variable speed pulleys, also known as adjustable pulleys or variable pitch pulleys, allow for easy adjustment of the pulley diameter. By changing the pulley diameter, the speed ratio between the driving and driven components can be varied, providing flexibility in system performance. Variable speed pulleys are commonly used in applications where adjustable speed control is required, such as in machinery with varying load conditions.
  • Idler Pulleys: Idler pulleys are used to change the direction of the belt or to provide additional support and tension. They do not transmit power themselves but play a crucial role in maintaining proper belt tension and alignment, improving system performance and reducing belt wear.
  • Step Pulleys: Step pulleys have multiple grooves or steps of different diameters. By changing the belt's position on different steps, the effective pulley diameter and speed ratio can be adjusted. Step pulleys are commonly used in applications where discrete speed changes are required, such as in drill presses or milling machines.

The choice of different types of belts and pulleys can have a significant impact on system performance. Factors such as power transmission accuracy, torque capacity, grip, efficiency, speed control, and system flexibility can be influenced by the selection of appropriate belt and pulley types. Understanding the specific requirements of the application and considering factors such as load conditions, speed variation needs, and environmental conditions can help determine the most suitable belt and pulley combination for optimal system performance.
