3. Components

A sheave typically consists of a grooved wheel, bearings, and a shaft for mounting.

4. Operation

As the sheave rotates, it helps to transmit power and change the direction of the force applied.

5. Types

There are different types of sheaves used in various applications, including V-belt sheaves, timing belt sheaves, and wire rope sheaves.

What are sheaves used for?

1. Power Transmission

Sheaves are used to transmit power from one component to another in machinery and equipment.

2. Lifting Applications

Sheaves are commonly used in lifting systems to guide ropes or cables for lifting heavy loads.

3. Directional Changes

Sheaves help to change the direction of the force applied by guiding belts or ropes around the pulley.

4. Tension Control
