What is a belt tensioner?
The tensioner is a belt tensioning device belonging to the automobile transmission system. It is mainly composed of a fixed housing, a tensioning arm, a wheel body, a torsion spring, a rolling bearing and a spring sleeve. The belt tensioner is used to adjust the tightness of the belt, reduce the vibration of the belt during operation and prevent the belt from slipping to a certain extent, ensuring the normal and stable operation of the transmission system. It is generally replaced together with the belt, idler and other cooperative accessories. The belt is a wearing part in automobile parts. When the belt is used for a long time, it is prone to wear. When the groove of the belt is worn deep and narrow, it will appear to be stretched. At this time, a hydraulic unit or damping needs to be performed through a tensioner. Spring, and the tensioner wheel can automatically adjust according to the degree of wear of the belt. Therefore, the belt tensioner wheel installed on the car can make the belt run more smoothly, reduce noise and prevent slipping.
The principle of belt tensioner:
The belt tensioner requires a certain amount of torque to maintain the proper tension of the belt during use and avoid belt slippage and elongation caused by aging or wear. When the belt tensioner is running, the belt can cause vibration in the tensioner, which will accelerate the wear of the belt and the tensioner. Therefore, in order to avoid this situation, we need to add a resistance mechanism to the tensioner. However, because the belt tensioner is affected by different parameters, its relationship with torque and resistance is complicated. The change in torque directly affects the change in resistance, and is the main factor affecting resistance. The parameters of the torsion spring are also the main factor affecting torque. Therefore, in order to better improve the resistance value of the belt tensioner, it is necessary to appropriately reduce the pitch diameter of the torsion spring.
The main function of the belt tensioner is to adjust the tightness of the timing belt, reduce the vibration of the belt during operation, prevent the belt from slipping and ensure the normal and stable operation of the transmission system. Although the belt tensioner pulley has powerful performance, its service life is short. Many car owners complain that the belt tensioner is broken before the belt is broken. When this happens, the timing belt and tensioner pulley should be replaced together. Therefore, HDAG tensioner suggest that under normal circumstances, the belt tensioner should be replaced every 3-5 years or about 80, PR4-YC timing belt tensioner pulley for LADA ba3 largus kamaz Gazelle Gazel Gazon Granta Kalina Gaz
