Belt tensioner pulley's structure

Structure

• Pulley: The pulley is the rotating part that comes into direct contact with the belt. It is usually made of high - strength materials like steel or aluminum alloy to withstand the forces exerted by the belt and the rotational speed. The surface of the pulley is precisely machined to provide a good grip on the belt and reduce wear.
• Tensioning Mechanism: There are different types of tensioning mechanisms. Some belt tensioner pulleys use a spring - loaded design. The spring applies a constant force to the pulley, adjusting the tension as the belt stretches over time or due to changes in operating conditions. Others may use a hydraulic or pneumatic system to maintain the appropriate tension.
