Industrial double synchronous belt matters needing attention when using: pay attention to the product surface when the choose and buy neat, belt is not twisted on the deformation and toothed. Synchronous belt products should be forbidden twists and turns, in order to avoid damage skeleton material, affect the intensity of belt. Synchronous belt products need to cut belt is forbidden, in order to avoid the belt early damage. Avoid contact with the chemicals synchronous belt products. Synchronous belt products try to avoid contact with oils, water for a long time. Synchronous belt linear vibration was used in a single motor linear vibrating screen, to replace the synchronous belt transmission box or cylindrical gear drive vibrator, drive the two synchronous reverse rotation axis, sieve machine also makes linear motion as a result, the synchronous belt linear vibrator used no matter in the double or single motor driven motor vibrating screen, are the two shaft through a synchronous belt, driving on the shaft of two eccentric block group of synchronous reverse rotation, of eccentric block in the centrifugal force generated by the instantaneous position along the direction of vibration on the component always overlap, and in the component will offset each other, thus forming a single along the direction of vibration exciting force, driving machine for reciprocating linear motion.
