It is typically mounted on a spring-loaded arm or bracket, which applies tension to the belt as it rotates. This tension ensures that the drive belt remains properly engaged with the motor pulley and the drum pulley, allowing for smooth and efficient rotation of the dryer drum during the drying cycle Prevention of Slippage: Adequate tension on the drive belt is essential to prevent slippage or slipping of the belt during operation. The idler pulley wheel applies consistent tension to the belt, helping to ensure that it stays securely in place and maintains proper contact with the motor and drum pulleys. This prevents the belt from slipping and ensures that power is effectively transferred from the motor to the drum, allowing for efficient drying of laundry Noise Reduction: A properly tensioned drive belt helps minimize noise and vibration during the operation of the dryer. The idler pulley wheel plays a role in reducing noise by ensuring that the belt remains firmly in place and does not slip or vibrate excessively during rotation. This contributes to a quieter drying experience for the user, Weight: 0.17 Pounds, Manufacturer: Supplying Demand
