A Belt Tensioner maintains proper tension of the belt for the air conditioning system in the engine. The refrigerator compressor connects to the engine drive using the belt. The belt tensioner typically consists of a pulley mounted on a pivot arm or bracket. The arm or bracket is designed to apply a controlled amount of tension to the belt by adjusting the position of the pulley. This adjustment can be achieved through various mechanisms, depending on the specific design and application.Attributes: • Withstands engine operation conditions and vibrations• Arm travel at 71° minimum• Mounted to get suitable tension on the belt• Guides the belt without slippingApplication:A Belt Tensioner in refrigerator compressors in engines for maintaining proper tension to get smooth operation of the unit. Its main purpose is to maintain the proper tension of the belt, ensuring optimal performance and preventing slippage or belt failure.
