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. |

Their design characteristics, combined with the use of appropriate V-belts and proper tensioning, facilitate efficient power transmission, reliable operation, and effective transport of materials in various industrial applications.
What are the primary components and design features of a V pulley?
A V pulley, also known as a V-belt pulley or sheave, consists of several primary components and design features that enable its functionality. Here’s an explanation of the primary components and design features of a V pulley:
1. Body:
The body of a V pulley is the main structural component. It is typically made of metal, such as cast iron or steel, to provide strength and durability. The body is designed to support the V-belt and transmit power from the driving source to the driven component. It may have a solid construction or be split into two halves for easy installation or replacement.
2. Groove:
The groove is a key design feature of a V pulley. It is a V-shaped channel or groove that runs along the outer circumference of the pulley. The groove is specifically designed to accommodate the V-belt with a corresponding trapezoidal cross-section. The V shape of the groove enhances the grip between the pulley and the belt, ensuring efficient power transmission and reducing the risk of slippage.
3. Diameter:
The diameter of a V pulley refers to the distance across its outer circumference. It plays a crucial role in determining the speed ratio and torque transmission of the power transmission system. By changing the diameter of the pulley, different speed ratios can be achieved between the driving source and the driven component. Larger pulley diameters generally result in higher belt speeds and lower torque, while smaller diameters lead to slower belt speeds and higher torque.
4. Number of Grooves:
V pulleys can have a single groove or multiple grooves, depending on the specific application. The number of grooves corresponds to the number of V-belts used in the power transmission system. Multiple grooves allow for the simultaneous power transmission to multiple driven components, such as in systems with multiple accessories or pulleys in automotive engines.
5. Tapered or Straight Design:
V pulleys can have a tapered or straight design, depending on the requirements of the application. Tapered pulleys are wider at one end and narrower at the other, allowing for easier belt installation and improved belt tracking. Straight pulleys have a consistent width along their entire circumference and are commonly used in applications where belt tracking is not a significant concern.
6. Surface Finish:
The surface finish of a V pulley is important for optimizing the performance and lifespan of the V-belt. The pulley’s surface should be smooth and free from any roughness or irregularities that could cause excessive belt wear or damage. Proper surface finish ensures proper belt contact, reduces friction, and enhances the overall efficiency of the power transmission system.
7. Mounting Mechanism:
V pulleys are mounted on shafts or bearings using various mounting mechanisms, such as set screws, bolts, or keyways. The mounting mechanism ensures secure and reliable attachment of the pulley to the rotating shaft, allowing for the transmission of rotational motion and torque.
By considering these primary components and design features, engineers can select and design V pulleys that are suitable for specific applications, ensuring efficient power transmission and reliable operation in mechanical systems.
