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.Lagging: It 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 does a belt pulley function in power transmission?
A belt pulley plays a crucial role in power transmission by enabling the transfer of rotational motion and torque between rotating shafts. It functions as a mechanical device that connects the driving shaft to the driven shaft through a belt or a rope. The rotational motion of the driving shaft is transmitted to the driven shaft via the belt pulley, allowing power to be transferred from one shaft to another. Here’s a detailed explanation:
A belt pulley functions in power transmission through the following process:
- The driving shaft, which is typically connected to a motor or an engine, rotates and generates rotational motion and torque.
- The belt pulley is mounted on the driving shaft, and its grooved rim is designed to engage with a belt or a rope.
- A belt or a rope is wrapped around the groove of the belt pulley, creating a secure connection between the pulley and the belt.
- As the driving shaft rotates, the belt or rope, in contact with the grooved rim of the pulley, starts to move.
- The movement of the belt or rope causes the belt pulley to rotate.
- Since the belt pulley is connected to the driven shaft, which is the output shaft of the system, the rotational motion of the pulley is transferred to the driven shaft.
- Consequently, the driven shaft starts to rotate at the same speed and direction as the driving shaft.
- The rotational motion and torque generated by the driving shaft are effectively transmitted to the driven shaft through the belt pulley and the belt or rope.
It’s important to note that the design and configuration of the belt pulley, along with the belt or rope, are essential for efficient power transmission. The groove profile of the pulley should match the belt or rope profile to ensure proper engagement and prevent slippage. The tension in the belt or rope should be appropriately adjusted to maintain a secure connection between the pulley and the belt. Additionally, the size and ratio of the pulleys connected by the belt can be adjusted to control the speed and torque output, providing flexibility in power transmission.
In summary, a belt pulley functions in power transmission by connecting the driving shaft to the driven shaft through a belt or a rope. It transfers the rotational motion and torque generated by the driving shaft to the driven shaft, allowing power to be transmitted between the two shafts. The design, configuration, and tensioning of the belt and the pulley are crucial for efficient and reliable power transmission in mechanical systems.
