Introduction to Belt Tensioner Pulley

Design and Working Principle of Belt Tensioner Pulley

The belt tensioner pulley plays a crucial role in maintaining the proper tension of the belt in a vehicle’s engine system. It is designed to apply and maintain the correct amount of tension on the belt to prevent slippage and ensure smooth operation of the engine components. The working principle involves the pulley rotating with the belt, exerting the necessary force to keep the belt taut and functioning effectively.
