79 inch serpentine belt

The serpentine belt operates using the engine's crankshaft pulley as its primary drive. As the engine runs, the crankshaft rotates the belt, which, in turn, engages various accessory pulleys. This movement powers the alternator, which generates electricity for the vehicle’s electrical system and battery. Additionally, the belt drives the power steering pump, enabling easier steering, supports the air conditioning system to keep the cabin cool, and can also power the water pump in some vehicle designs. The continuous action of the serpentine belt ensures that these critical systems function smoothly and efficiently.

The working mechanism of tooth belts is based on the interaction between the belt's teeth and the pulley grooves. When the pulley rotates, the teeth of the belt mesh with those of the pulley, creating a mechanical link that transmits torque. This system allows for high torque transfer with minimal backlash, which is particularly advantageous in applications requiring precise positioning, such as in robotics or CNC machines. Additionally, tooth belts operate quietly compared to chain drives, making them suitable for environments where noise reduction is essential.
