1604641100 ATLAS COPCO Industrial Air Compressor Drive Belt

I. Types and Characteristics of Drive Belts

Common Types

In Atlas Copco air compressors, the commonly used drive belts include V-belts, multi-rib belts, and synchronous belts, etc. The specific type of drive belt used for each air compressor is selected based on parameters such as power and speed:

V-belt: Transmits power through the contact of both sides with the pulley grooves. It has a simple structure and low cost, and is suitable for small to medium power models.

Multi-rib belt: Combines the advantages of flat belts and V-belts, featuring a large contact area, high power transmission capacity, and stable operating performance. They are often used in medium to large power air compressors.

Synchronous belt: Transmits power through the meshing of belt teeth and pulley teeth. They have high transmission accuracy, no slipping, and are suitable for models with high requirements for speed synchronization.

Material Characteristics Generally, rubber or polyurethane is used as the base material, with high-strength fibers embedded. 2. Common Faults and Their Effects

Slippage

Due to the slackness, wear, or contamination by oil of the transmission belt, the friction force will decrease, resulting in a decline in transmission efficiency, insufficient output pressure from the air compressor, overheating of the motor, and in severe cases, the friction may even cause the transmission belt to burn out due to overheating.

Breakage or Cracking

After long-term use, the material ages, or due to improper installation or misalignment of the pulley, local stress concentration may occur, which may lead to the breakage of the transmission belt, causing the air compressor to suddenly stop.

Uneven Wear

Wear of the pulley groove, installation eccentricity deviation, or uneven tension of the transmission belt may all cause local excessive wear of the transmission belt, shortening its service life. 3. Maintenance and Replacement Key Points

Daily Inspection

Regularly check the tension of the drive belt: Press the middle position of the drive belt, and its curvature is usually 10 - 15 millimeters. If it is too loose, it is prone to slipping; if it is too tight, it is likely to damage the bearings and the drive belt.

Check for cracks, wear, and oil stains on the surface. If there are oil stains, clean and check for any oil leakage points.

Check if the pulley is aligned, and if there is any wear or deformation.

Replacement Timing

Replace immediately if there are obvious cracks, delamination, excessive wear, or breaks.

Perform preventive replacement according to the recommended cycle in the equipment manual.

It is recommended to replace the entire set to avoid mixing new and old drive belts, which may cause uneven force distribution. Installation Precautions

Select a drive belt that matches the original model.

Ensure that the axis of the pulley is parallel, adjust the tension after installation, and avoid being too loose or too tight.

Avoid using sharp objects to scratch the drive belt during installation.
