Correct installation process of PU synchronous belt: turn off the power supply, shield, unscrew the motor mounting bolts. Mobile motor make the PU synchronous belt enough slack, can remove the belt do not need to pry open, don't put the belt to pry. Installing a synchronous belt, if the center distance of two pulleys can be moved, must shorten the belt wheel center distance, installed after the synchronous belt, again to reset the center distance. If there is tension wheel, to relax the tension wheel, then install synchronous belt, tension wheel on reload. Remove the old belt, check to see if there is abnormal wear could mean transmission device design or maintenance problems to synchronous belt pulley jacket, don't too hard and hard or with a screwdriver to pry synchronous belt, in order to prevent the synchronous belt in the tensile layer produces imperceptible break phenomenon appearance. Design pulley, had better choose the structure of the two shafts can be closer to each other, if the structure does not allow, is the best fit with PU synchronous belt and pulley to the corresponding axis. Clean the belt and pulley, cloth should be stained with a little less volatile liquid to wipe, soak in the detergent or use cleaner scrub belts are not desirable. To remove grease and dirt, use sandpaper or sharp objects scraped, obviously is not desirable. Belt must be kept dry before install and use.
