sheaves & pulleys

Sheaves & Pulleys

  1. Sheaves & Pulleys are mechanical devices used to transmit power between axles by means of a belt, rope, or chain.
  2. They are commonly used in machinery for lifting heavy loads or changing the direction of a force.
  3. Sheaves & Pulleys consist of a wheel with a groove around its circumference where a belt or rope can run.
  4. They come in various sizes and materials depending on the application and load requirements.
  5. Proper maintenance and lubrication are essential for the smooth operation of sheaves & pulleys.

Types of Sheave Pulleys

  1. V-Belt Pulleys: Used with V-belts to transmit power efficiently.
  2. Timing Belt Pulleys: Synchronized motion between shafts using toothed belts.
  3. Flat Belt Pulleys: Suitable for light-duty applications with flat belts.
  4. Rope Sheaves: Designed for wire ropes to lift heavy loads.
  5. Chain Sheaves: Used with chains to transmit power in industrial applications.
  6. Cable Sheaves: Ideal for guiding cables in various directions.

What is a sheave on a pulley

  1. A sheave on a pulley is a wheel with a groove around its circumference to guide a belt, rope, or chain.
  2. It helps change the direction of force and transmit power efficiently.
  3. The groove ensures that the belt or rope stays in place during operation.
  4. Sheaves on pulleys come in different sizes and materials to suit specific applications.
  5. They play a crucial role in lifting heavy loads and machinery operation.

What are sheaves used for?

  1. Sheaves are used to change the direction of a force in machinery.
  2. They help transmit power between axles using belts, ropes, or chains.
  3. Sheaves are essential in lifting heavy loads in construction and industrial settings.
  4. They provide mechanical advantage by increasing or decreasing speed or force.
  5. Sheaves guide and support belts or ropes to ensure smooth operation.
  6. They are crucial components in pulley systems for various applications.

Process of Sheave Pulley


The mold is created to shape the sheave pulley according to design specifications.

The raw materials are melted and poured into the mold to form the sheave pulley shape.

Raw Materials

High-quality materials such as steel or aluminum are used to ensure durability and strength.


The sheave pulley is manufactured with precision and attention to detail for optimal performance.


Each sheave pulley undergoes rigorous testing to ensure quality and reliability.

Antirust Treatment

A protective coating is applied to prevent corrosion and increase longevity.

Separate Inspection

Each sheave pulley is individually inspected to meet quality standards before assembly.


Identification marks are added for traceability and quality control purposes.

How do you adjust sheave pulleys?

  1. Refer to the manufacturer’s guidelines for specific adjustment instructions.
  2. Use the appropriate tools such as a wrench or screwdriver to loosen the locking mechanism.
  3. Adjust the position of the sheave pulley by moving it along the shaft or changing the belt tension.
  4. Ensure the sheave pulley is aligned correctly with other components for smooth operation.
  5. Tighten the locking mechanism securely once the adjustment is complete.
  6. Test the sheave pulley to ensure proper alignment and tension before operation.
  7. Regularly check and readjust the sheave pulleys as part of routine maintenance.
