Types of Sheave Pulleys

1. Fixed Pulleys

Fixed pulleys have a stationary axle and are used to change the direction of a force.

2. Movable Pulleys

Movable pulleys have a movable axle and are used to amplify the force applied.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to provide mechanical advantage.

4. Block and Tackle Pulleys

Block and tackle pulleys use multiple pulleys to increase the lifting force.

5. Snatch Blocks

Snatch blocks are used for redirecting a line or cable without reeving it.

6. Idler Pulleys

Idler pulleys help to maintain tension in the belt or rope passing over it.

What is a Sheave on a Pulley?

1. Definition

A sheave is a pulley with a grooved wheel designed to hold a belt, rope, or cable.

2. Function

The sheave rotates on an axle and is used to change the direction of a force or transmit power.

3. Components

A sheave consists of a wheel, axle, and bearings to facilitate smooth rotation.

4. Material

Sheaves are typically made from materials such as steel, aluminum, or plastic, depending on the application.

5. Size

Sheaves come in various sizes to accommodate different belt or rope diameters and loads.

What are Sheaves Used For?

1. Load Distribution

Sheaves are used to distribute the load evenly across multiple belts or ropes.

2. Power Transmission

Sheaves transmit power from one rotating shaft to another using belts or ropes.

3. Direction Change

Sheaves change the direction of a force by redirecting the path of the belt or rope.

4. Tension Control

Sheaves help maintain proper tension in the belt or rope to prevent slippage or breakage.

5. Speed Control

By changing the size of the sheave, the speed of the rotating shaft can be controlled.

6. Mechanical Advantage

Sheaves provide mechanical advantage by amplifying the force applied to the belt or rope.
