PRODUCT DETAIL
The tensioning wheel is mainly composed of fixed shell, tensioning arm, wheel body, torsion spring, rolling bearing and spring shaft sleeve. It can automatically adjust the tensioning force according to the different tightness of the belt, so as to make the transmission system stable, safe and reliable.
The tensioning wheel is a vulnerable part of automobile and other spare parts. The belt is easy to wear after a long time, and the belt groove will appear to be elongated after being worn deep and narrow. The tensioning wheel can be automatically adjusted according to the wear degree of the belt through the hydraulic unit or damping spring. In addition, with the tensioning wheel, the leather belt runs more stably, has less noise, and can prevent slipping
The tensioning wheel is a routine maintenance item, which generally needs to be replaced for 60000-80000 km. Usually, if there is an abnormal roar at the front end of the engine or the position of the tensioning force mark of the tensioning wheel deviates too much from the center, it means that the tensioning force is insufficient. At 60000-80000 km (or when the front-end accessory system makes abnormal noise), it is recommended to replace the belt, tensioner, idler, single wheel of generator, etc.
The function of the tensioning pulley is to adjust the tightness of the belt, reduce the vibration of the belt during operation, prevent the belt from slipping to a certain extent, and ensure the normal and stable operation of the transmission system It is generally replaced with belt, idler pulley and other cooperative accessories to avoid worries
In order to maintain proper belt tightening force, avoid belt slip and compensate the elongation caused by belt wear and aging, a certain torque is required for the tensioning wheel in the actual use process. When the belt tensioner runs, the moving belt may cause vibration in the tensioner, which will lead to premature wear of the belt and tensioner. To this end, add a resistance mechanism to the tensioning wheel. However, there are many parameters that affect the torque and resistance of the tensioning wheel, and the influence of each parameter is different, so the relationship between the components of the tensioning wheel and the torque and resistance is very complex. The change of torque directly affects the change of resistance, and it is the main influencing factor of resistance. The main factor affecting torque is the parameters of torsion spring. Properly reducing the pitch diameter of the torsion spring can increase the resistance value of the tensioning wheel
