Application field of tensioning wheel

summary

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 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 parts. The belt is easy to be extended after a long time. Some tensioning wheels can automatically adjust the tension of the belt. In addition, with the tensioning wheel, the belt runs more smoothly, has less noise, and can prevent slipping.

The tensioning pulley is used to adjust the tightness of the timing belt. It is generally replaced with the timing belt to avoid worries. Other parts don't need to be replaced, just go for regular maintenance.

working principle

In order to maintain proper belt tensioning 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 is running, 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 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 improve the resistance value of the tensioning wheel.
