Whether replacing the belt or installing the belt on a new transmission device, it is recommended to follow the following steps.
- Turn off the power, remove the protective cover, and loosen the mounting bolts on the motor base to allow the motor to move back and forth.
- Move the motor to make the belt loose enough to easily remove it. Never use tools to pry the belt.
- Remove the old belt and check for any abnormal wear. Excessive wear may indicate problems in the design or maintenance of the transmission system.
- Choose a suitable belt replacement.
- Cleaning belts and pulleys: A cloth should be dipped in a small amount of non volatile liquid to wipe the belt. Do not soak it in cleaning agents or use cleaning agents to brush the belt. Do not use sandpaper or sharp objects to wipe the belt. The belt must be kept dry before installation and use.
- A simple way to check for cracks or wear on the belt is to use a groove gauge. If there is excessive wear, the pulley must be replaced.
- Check if each pulley is on a flat surface.
- Check the symmetry, durability, and lubrication of other transmission components such as bearings and shaft sleeves.
- For transmission devices that use multiple belts, all belts must be replaced at once. If only one belt is replaced on multiple belt transmission devices, the new belt may have the appropriate tension, but the remaining old belt will be too loose, and most of the power may be borne by this new belt, causing premature damage to the new belt.
- Tighten the center distance of the transmission device, rotate the driving wheel a few times by hand, and use a belt tension measuring instrument to check if the tension is appropriate.
- Tighten the assembly bolts of the motor to the specified torque.
- Replace the protective cover.
- Suggest adopting a trial operation procedure. This program starts the transmission device, runs at full load, then stops, checks and adjusts the tension to the recommended value. The operation of the belt under full load can make the belt completely match the groove of the wheel. If possible, the belt should run for at least one hour. The trial run program can reduce the number of times the tension can be readjusted in the future.
- During the trial operation, the operation should be closely monitored to see if there is any abnormal vibration and listen carefully for any abnormal noise. It is best to turn off the machine after running for a period of time and check the heating condition of the bearings and motor; If it feels too hot to the touch, it may be due to the belt being too tight, the bearings being asymmetrical, or incorrect lubrication.
- For synchronous belts, there is minimal relaxation during operation, so it is generally not necessary to readjust the tension. However, we still recommend starting the device and observing its performance to see if there is any abnormal vibration and listen carefully for any abnormal noise. It is best to turn off the machine after running for a period of time and check the heating condition of the bearings and motor; If it feels too hot to the touch, it may be due to the belt being too tight, the bearings being asymmetrical, or incorrect lubrication.
