Types of Sheave Pulleys

1. Fixed Pulleys

Fixed pulleys have a stationary axle and are used to redirect the force in a system.

2. Movable Pulleys

Movable pulleys can move along the axle to provide mechanical advantage in lifting systems.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to increase the mechanical advantage further.

4. Block and Tackle Pulleys

Block and tackle pulleys use multiple pulleys in a system to create a powerful lifting mechanism.

5. Snatch Blocks

Snatch blocks are used for redirecting a line in different directions and are commonly used in rigging applications.

6. Idler Pulleys

Idler pulleys are used to guide belts and chains, providing tension and alignment in the system.

What is a Sheave on a Pulley?

1. Function

A sheave is a grooved wheel or pulley used with a belt or chain to change the direction or point of application of a pulling force.

2. Material

Sheaves are commonly made of metal, plastic, or other durable materials to withstand heavy loads and friction.

3. Design

Sheaves are typically designed with grooves to prevent the belt or chain from slipping off during operation.

4. Size

The size of the sheave determines the speed and force transmission capabilities of the system.

5. Applications

Sheaves are used in various industries such as textile, automotive, and construction for power transmission and control.

What are Sheaves Used For?

1. Power Transmission

Sheaves are used to transmit power from one rotating shaft to another in a machinery system.

2. Speed Control

Sheaves help to control the speed of the machinery by adjusting the diameter of the sheave.

3. Direction Change

Sheaves are used to change the direction of the force applied by the belt or chain in the system.

4. Load Distribution

Sheaves distribute the load evenly across the system, reducing strain on individual components.

5. Tension Adjustment

Sheaves help to adjust the tension in the system by changing the position of the sheave.

6. System Alignment

Sheaves ensure proper alignment of belts and chains in the machinery system for smooth operation.

Separate Inspection

Each sheave pulley is individually inspected for any defects or imperfections before packaging.


Each sheave pulley is marked with relevant information for identification and traceability.

How do you adjust sheave pulleys?

1. Adjusting Belt Tension

Loosen the mounting bolts, adjust the position of the sheave, and retighten the bolts to change belt tension.

2. Changing Sheave Position

Move the sheave along the shaft or axle to change the speed or direction of the machinery.

3. Replacing Sheave Size

Replace the sheave with a different size to adjust the power transmission capabilities of the system.

4. Lubrication

Ensure proper lubrication of the sheave and belt to reduce friction and improve performance.

5. Alignment

Check and adjust the alignment of the sheave pulleys to prevent belt slippage and wear.

6. Regular Maintenance

Perform regular maintenance checks on the sheave pulleys to ensure optimal performance and longevity.
