Sprinter 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.

1, position: auto tensioner is generally arranged on the inside of the loose edge, so that the belt is only subject to one-way bending; At the same time, in order to ensure that the envelope Angle of the small belt pulley is not reduced too much, the tension wheel should be installed as close as possible to the large belt pulley.

2, function: serpentine belt pulley is a belt drive tension device, when the center distance of the belt can not be adjusted, you can use the tension wheel to tighten the belt.

3, composition: timing tightening wheel is mainly composed of fixed shell, tensioning arm, wheel body, torsion spring, rolling bearing and spring sleeve, etc., can automatically adjust the tension according to the different tightness of the belt, so that the transmission system is stable, safe and reliable.

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.
