car parts belt tensioner

The tensioner is divided into accessory tensioner (generator belt tensioner, air conditioning belt tensioner, mechanical supercharger belt tensioner, etc.) and timing belt tensioner according to the location. The tightening wheel can be divided into mechanical automatic tightening wheel and hydraulic automatic tightening wheel according to the tightening way.

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 in the actual use of the tightening wheel. When the belt tension wheel is running, the moving belt may cause vibration in the belt tension wheel, which can cause premature wear of the belt and tension wheel. To this end, a resistance mechanism is added to the tightening wheel. However, because there are many parameters affecting the torque and resistance of the tightening wheel, the influence of each parameter is not the same, so the relationship between the parts of the tightening wheel and the torque and resistance is very complicated. The change of torque directly affects the change of resistance, and is the main influencing factor of resistance, and the main influencing factor of torque is the parameter of torsion spring. Properly reducing the middle diameter of the torsion spring can increase the resistance value of the tension wheel.
