drive belt tensioner

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.

The main function of the idler pulley is to change the steering of the driven wheel, increase the transmission distance, adjust the pressure angle, etc. The belt idler pulley is a part of the gear train that plays a transitional role and will not change the transmission relationship. It is to make the force of the gear train more reasonable or to meet the layout of the entire transmission system. Its function is only to change the steering, but not to change the transmission ratio. The wheelbase can be extended through the v belt tensioner pulley. The number of its teeth has no effect on the value of the transmission ratio, but it will have an impact on the steering of the last wheel.
