Belts are essential components in various mechanical systems, serving to transmit power between different parts. A V-belt, characterized by its V-shaped cross-section, is a traditional belt type used in many applications due to its simplicity and effectiveness. A fan belt, often a type of V-belt or serpentine belt, drives the engine cooling fan in automotive applications. A ribbed belt, also known as a serpentine belt, is a modern, high-performance belt with multiple longitudinal ribs, offering high power transmission efficiency and flexibility. A timing belt, also toothed or cogged, is a specific type of belt used in internal combustion engines to synchronize the rotation of the crankshaft and the camshaft. Each of these belts has unique design characteristics, making them suitable for different applications.
