Introduction

The Cummins 4994780 V Ribbed Belt is a critical component in commercial trucks, facilitating the transfer of power from the engine to auxiliary components such as the alternator, air conditioning compressor, and other engine-driven accessories. This ensures these systems function correctly, supporting the truck’s performance and efficiency ¹.

Basic Concepts of V Ribbed Belts

V Ribbed Belts, characterized by their trapezoidal cross-section, engage more effectively with pulleys than flat belts, enhancing efficiency and durability. They operate on the principle of frictional drive, where the belt’s ribs fit into the grooves of the pulleys, transmitting power with minimal slippage. This design allows them to handle higher loads and operate at greater speeds, making them suitable for demanding applications like those in commercial trucks ².
