Installation requirements and use of belt drives (1) When installing the transmission belt, the belt should be put on after reducing the center distance between the two wheels. Do not pry it hard, so as not to damage the belt and reduce the service life. (2) When installing the pulley, the axes of the two wheels must be parallel; the centerline of the wheel groove must also be aligned, otherwise it will cause premature wear on one side of the V-belt working surface. (3) When choosing a belt, the model and nominal length must not be mistaken, so as to ensure the correct position in the re-discussion groove of the V-belt section. (4) When the number of V-belts in the same transmission is large, it is not possible to use new and old belts with different lengths to avoid uneven load distribution and accelerated belt wear. (5) Prevent the tape from contacting with mineral oil, acid, alkali and other media to avoid deterioration. It is also not suitable to expose to the sun. (6) In order to ensure safe operation, the belt drive must be blocked by a protective cover. Belt drives are generally divided into parallel belt drives, V-belt drives and synchronous toothed belt drives.
