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.

What is a V pulley, and how does it function in mechanical systems?

A V pulley, also known as a V-belt pulley or a sheave, is a mechanical component used in power transmission systems. Here’s an explanation of what a V pulley is and how it functions:

A V pulley is a pulley with a V-shaped groove on its outer circumference. It is typically made of metal, such as cast iron or steel, and is designed to work in conjunction with V-belts, which are flexible rubber belts with a trapezoidal cross-section. The V pulley and V-belt combination form a friction-based power transmission system.

Function:

The primary function of a V pulley is to transmit power between a driving source, such as an electric motor or an engine, and a driven component, such as a pump, a generator, or a machine. The V-belt wraps around the V pulley, fitting into the groove, and forms a frictional contact. When the driving source rotates the V pulley, the friction between the V-belt and the pulley enables the transfer of rotational motion and torque to the driven component.

Advantages:

1. Slip Reduction: The V-shaped groove on the pulley and the corresponding shape of the V-belt create a wedging action that enhances the grip between the pulley and the belt. This reduces the likelihood of slippage, even under heavy loads or during sudden changes in speed or direction.

2. High Torque Transmission: The design of the V pulley allows for the transmission of high levels of torque. The wedging action and increased contact area between the pulley and the belt enable efficient power transfer without excessive belt tension.

3. Speed Variation: By changing the diameter of the V pulley, different speed ratios can be achieved in the power transmission system. This provides flexibility in adjusting the speed of the driven component relative to the driving source, allowing for proper matching of operational requirements.

4. Damping Effect: The flexibility of the V-belt and the slight elasticity of the rubber material provide a damping effect, which helps mitigate vibrations and shocks in the mechanical system. This contributes to smoother operation, reduced noise, and increased component longevity.

5. Ease of Installation and Maintenance: V pulleys are relatively easy to install and maintain. The V-belts can be easily tensioned or replaced when necessary, and the pulleys can be readily mounted on shafts or bearings using standard mounting techniques.

Applications:

V pulleys find widespread use in various mechanical systems, including:

  • Automotive applications, such as in engines, water pumps, and air conditioning compressors.
  • Industrial machinery, such as conveyor systems, agricultural equipment, and machine tools.
  • HVAC systems, where V pulleys are used in fans, blowers, and pumps.
  • Power transmission systems in appliances, such as washing machines, dryers, and power tools.

By utilizing V pulleys in mechanical systems, efficient and reliable power transmission can be achieved, enabling the smooth operation of various devices and equipment.
