Types of Power Transmission and Industrial Drive Belts We Offer

The primary role of a transmission belt is to transfer rotation from a powered pulley to one or more secondary-driven pulleys. Belts also act as a safety mechanism by slipping or breaking under maximum shock loads, protecting equipment from more severe damage. Since they are more economical and easier to replace than other options like chains and gears, transmission belts are the top choice for many operations requiring continuous power.

Because these belts must meet the design requirements of specific machines and applications, many factors come into play when purchasing them, including torque amount, center distance, rotational speed, operating temperature and more. Most industrial drive belts consist of rubber material and are part of different categories, including:

• V-belts:V-belts are the most common and typically the most economical type of transmission belt. The product design is non-synchronous and works for applications where slippage is desirable. V-belts have several subcategories, including variable-speed and double-sided V-belts that are more flexible and can support higher loads.
• Synchronous belts:Synchronous belts, often called timing belts, prevent slippage by meshing their teeth with the sprocket grooves. These belts are ideal for applications requiring precision positioning between shafts with high mechanical efficiency. Many HVAC operations convert V-belt systems to synchronous belts to improve transmission and increase energy savings.
