Power interruption protection: When the clothes get tangled or the inner drum gets stuck, the belt will slip to reduce the force, preventing the motor from forcibly running and causing abnormalities, and providing overload protection. Transmission direction conversion: Combined with the design of the pulley, it changes the direction of the motor's power output, adapting to the forward and reverse washing requirements of the drum washing machine, enhancing the cleaning effect of rubbing the clothes. Adaptability to multiple operation modes: Compatible with standard wash, quick wash, and powerful wash among other programs. Through stable transmission, it ensures the accuracy of rotational speed in different modes, ensuring the consistency of washing effect. Reduction of energy loss: The high-quality belt has high transmission efficiency. During the power transmission process, no energy is lost, allowing the motor to output power to be more efficiently converted, helping to save energy and reduce electricity consumption.
