Exploring Belts

What are Belts?

Belts are flexible, continuous bands that transmit power and motion through friction between the belt and pulleys or sheaves. They are made from various materials, including rubber, leather, and synthetic polymers.

Types of Belts

A wide range of belt types is available, tailored to specific applications. Common types include:

• V-belts: Feature trapezoidal cross-sections that fit into matching grooves on pulleys, providing positive drive and higher power transmission efficiency.
• Flat belts: Composed of a flat surface that wraps around pulleys, suitable for high-speed applications with low power requirements.
• Timing belts: Have precisely spaced teeth that engage with matching sprockets, ensuring accurate and synchronous motion transmission.

Applications of Belts

Belts are commonly used in various industries, including:

• Power transmission: Connecting pulleys and shafts to transmit power in agricultural, automotive, and manufacturing machinery.
• Material handling: Conveying products in packaging, printing, and textile manufacturing.
