Product Description
Product Description
A conveyor will always consist of at least 2 pulleys, head pulley and tail pulley, with additional pulleys used depending on the configuration. Standard-duty pulleys are usually adequate for simple applications, but mine-duty and engineered pulleys are also available where heavy-duty pulleys are required.
Different kinds of conveyor pulleys
KONWEYOUR sells conveyor pulleys in all the following sub-categories:
Head pulleys
The head pulley is located at the discharge point of the conveyor. It usually drives the conveyor and often has a larger diameter than other pulleys. For better traction, the head pulley is usually lagged (with either rubber or ceramic lagging material).
Tail and CHINAMFG pulleys
The tail pulley is located at the loading end of the belt. It comes with either a flat face or a slatted profile (wing pulley), which cleans the belt by allowing material to fall between the support members.
Snub pulleys
A snub pulley improves the traction of the drive pulley, by increasing its belt wrap angle.
Drive pulleys
Drive pulleys, which can also be the head pulley, are driven by a motor and power transmission unit to propel the belt and material to the discharge.
Bend pulleys
A bend pulley is used for changing the direction of the belt.
Take-up pulley
A take-up pulley is used to provide the belt with the proper amount of tension. Its position is adjustable.

How do V pulleys contribute to efficient power transmission?
V pulleys play a crucial role in enabling efficient power transmission in mechanical systems. Here’s a detailed explanation of how V pulleys contribute to efficient power transmission:
1. Frictional Engagement:
V pulleys are designed with a V-shaped groove that matches the cross-section of V-belts. This groove profile allows for maximum contact area between the pulley and the belt, creating frictional engagement. The friction generated between the pulley and the belt enables the transfer of torque from the driving pulley to the driven pulley.
2. High Friction Coefficient:
V-belts used with V pulleys typically have a high friction coefficient. This characteristic enhances the grip between the belt and the pulley, ensuring efficient power transmission. The high friction coefficient helps prevent belt slippage, even under heavy loads or during sudden acceleration or deceleration.
3. Multiple V-Belt Contact Points:
Due to the V-shaped groove design, V pulleys provide multiple contact points along the length of the belt. This multi-point contact distributes the load across the belt and the pulley, reducing stress concentration on specific areas. It increases the overall power transmission capacity and improves the longevity of the belt and the pulley.
4. Flexibility and Shock Absorption:
V-belts used with V pulleys are flexible and elastic. This flexibility allows them to accommodate slight misalignments between the driving and driven pulleys, reducing stress on the system.
