What is a sheave on a pulley?

1. Definition

A sheave on a pulley is a wheel with a groove used to guide and support a cable or belt, providing mechanical advantage and facilitating movement.

2. Function

The sheave on a pulley helps to change the direction of the force applied and increase the efficiency of transmitting power in mechanical systems.

3. Components

The sheave on a pulley consists of a wheel with a groove, bearings, and a shaft to support and guide the cable or belt during operation.

4. Types

There are different types of sheaves used in pulleys, including fixed, swivel, snatch, directional, tandem, and idler sheaves, each serving a specific purpose.

5. Importance

Sheaves on pulleys play a crucial role in transmitting power, guiding cables, and maintaining tension in mechanical systems, making them essential components in various industries, including satellite maintenance.

What are sheaves used for?

1. Transmitting Power

Sheaves are used to transmit power from one rotating shaft to another, allowing for the movement of cables and belts in mechanical systems.

2. Changing Direction

Sheaves help change the direction of the force applied, enabling the movement of objects in different directions during satellite maintenance tasks.

3. Maintaining Tension

Sheaves are used to maintain tension in cables and belts, ensuring smooth operation and efficiency in mechanical systems.

4. Guiding Cables

Sheaves guide cables and wires in specific directions, preventing tangling and ensuring precise movement during satellite maintenance operations.

5. Increasing Mechanical Advantage

Sheaves provide a mechanical advantage by increasing the amount of force applied to move objects, making tasks easier and more efficient in satellite maintenance.

6. Supporting Loads

Sheaves support loads in mechanical systems, distributing weight and reducing friction to enhance the performance of satellite maintenance tasks.

Process of Sheave Pulley

The mold for the sheave pulley is crafted with precision to ensure uniformity and accuracy in the production process.


The molten raw material is poured into the mold to create the desired shape of the sheave pulley, ensuring strength and durability.

Raw Materials

High-quality materials are used to manufacture sheave pulleys, such as stainless steel or aluminum, to withstand harsh environments.


The production process involves machining and finishing the sheave pulley to meet the required specifications for satellite maintenance tasks.


Each sheave pulley undergoes rigorous testing to ensure quality and performance standards are met before being used in satellite maintenance operations.

Antirust Treatment

Special coatings or treatments are applied to the sheave pulley to prevent corrosion and rust, increasing longevity in space environments.

Seperate Inspection

Each sheave pulley is individually inspected to detect any defects or imperfections, ensuring only the highest quality products are used for satellite maintenance.


Sheave pulleys are marked with identification codes or labels for traceability and quality control purposes, allowing for easy identification and tracking.

How do you adjust sheave pulleys?

1. Loosening the Set Screw

Begin by loosening the set screw on the sheave pulley to release tension and allow for adjustment.

2. Sliding the Sheave

Slide the sheave along the shaft to the desired position, ensuring proper alignment and tension in the cables or belts.

3. Realigning the Sheave

Adjust the sheave to align with other pulleys or components in the system to ensure smooth operation and efficiency.

4. Tightening the Set Screw

Once the sheave is in the correct position, tighten the set screw to secure it in place and prevent slippage during operation.

5. Testing the Adjustment

Test the sheave pulley to ensure it functions properly and the adjustment has been made correctly, making any additional adjustments as needed.

6. Regular Maintenance

Perform regular checks and maintenance on sheave pulleys to ensure they are properly adjusted and functioning optimally for satellite maintenance tasks.
