Why Should The Timing Belt Be Tensioned

When installing the synchronous belt, it is necessary to carry out appropriate tensioning tasks, so as to ensure that the synchronous belt has a certain initial tension. If the initial tension is too small, the synchronous belt will jump due to poor tooth engagement during operation. At the moment of tooth skipping, the synchronous belt or belt teeth may be broken due to excessive tension. Too small initial tension will also reduce the accuracy of synchronous belt transmission and increase the noise during synchronous belt operation. Excessive initial tension will reduce the service life of the synchronous belt, increase the transmission noise, and increase the load force on the shaft and bearing, which will aggravate the heating of the bearing and reduce the service life of the bearing. Therefore, controlling the tension of synchronous belt is an important condition to ensure the normal task of synchronous belt transmission.
