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) .Â
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.Â
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:
Â
| 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:Â 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:Â 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:Â 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 an idler pulley, and what is its role in mechanical systems?
An idler pulley is a specific type of pulley that is used in mechanical systems. Here’s a detailed explanation of what an idler pulley is and its role in mechanical systems:
Definition:
An idler pulley is a pulley that is not directly connected to a power source or used for power transmission. Instead, it is used to guide and redirect a belt or rope in a system. The idler pulley is typically positioned in such a way that it changes the direction of the belt or rope, adjusts tension, or provides support to ensure smooth operation.
Role in Mechanical Systems:
The primary role of an idler pulley in mechanical systems is to maintain proper tension and alignment of belts or ropes. It helps to redirect the path of the belt or rope, ensuring that it remains in the correct position and stays engaged with other pulleys or components.
Here are some specific roles and functions of idler pulleys:
1. Belt Tension:
An idler pulley can be used to adjust and maintain the tension in a belt or rope. By adding or removing an idler pulley or adjusting its position, the tension in the belt can be properly controlled. This is crucial for preventing slippage, ensuring efficient power transmission, and extending the lifespan of the belt.
2. Directional Change:
In some systems, an idler pulley is strategically placed to change the direction of the belt or rope. By guiding the belt along a different path, the idler pulley allows the belt to reach components that would otherwise be inaccessible or difficult to connect directly. This enables flexibility in designing mechanical systems and facilitates the proper functioning of various components.
3. Belt Alignment:
An idler pulley helps maintain proper alignment of belts or ropes. It ensures that the belt remains centered on the pulleys and does not deviate from its intended path. Proper alignment is vital for efficient power transmission, as misaligned belts can cause increased friction, wear, and loss of energy.
4. Load Distribution:
In systems with multiple belts or ropes, an idler pulley can be used to distribute the load evenly. By introducing an idler pulley between two driving pulleys, the load can be divided, reducing stress on individual components and improving overall system performance.
5. Noise and Vibration Reduction:
An idler pulley can help reduce noise and vibration in mechanical systems. By providing additional support and tension to belts or ropes, it minimizes excessive movement and vibration, resulting in quieter operation and increased stability.
Idler pulleys are commonly found in various applications, including automotive engines, HVAC systems, conveyor systems, and industrial machinery. Their role in maintaining tension, guiding belts, adjusting alignment, distributing load, and reducing noise makes them essential components in ensuring the smooth and efficient operation of mechanical systems.
