In Testbook’s article, “V-Belts and Flat Belts: Learn Their Types, Advantages & Differences,” belt drives are highlighted as an efficient means to transmit power between two shafts that are not aligned in a straight line. Commonly used in applications such as automobiles, conveyor systems, and power transmission equipment, belt drives rely on belts and pulleys to transfer rotational power.

There are two primary types of belts used in these systems: V-Belts and Flat Belts. Flat belts are especially useful for transferring power across longer distances, as their broad design—wider than their thickness—enhances efficiency, achieving nearly 99% transmission efficiency. Flat belts are often seen in industrial settings like flour mills and mechanic shops, where high power over extended distances is essential.

Flat belts require secure joints to connect their ends, with three common methods:

  • Cemented Joints: Typically used with rubber and leather belts, these provide 80-85% of the belt’s strength.
  • Laced Joints: Made with rawhide or catgut strips, offering 50% of the belt’s strength.
  • Hinged Joints: Quick to assemble but only suitable for low-speed operations, providing 25% of belt strength.

V-belts, on the other hand, are ideal for applications requiring high-speed power transmission in compact spaces. Their unique shape provides better grip and reduces slippage, making them well-suited for heavy-duty applications.
