How to install industrial belts and maintain transmissions
2. Move the motor to make the belt slack enough to easily remove the belt. Never use tools to pry the belt.
3. Remove the old belt and check for abnormal wear. Excessive wear may mean problems with the design or maintenance of the transmission.
4. Choose a suitable belt replacement.
5. Clean the belt and pulley: wipe the cloth with a little non-volatile liquid, do not soak in detergent or use detergent to scrub the belt, do not wipe with sandpaper or scratch the belt with sharp objects. The belt must be kept dry before installation and use.
6. Check whether the pulley is cracked or worn. The simpler way is to use a standard wheel groove measuring tool to check. If the wear is excessive, the pulley must be replaced.
7. Check whether the pulleys are on the same plane.
8. Check the remaining parts of the transmission device, such as the symmetry, durability and lubrication of bearings and sleeves.
9. For transmissions that use multiple belts, all belts must be replaced at once. If only one belt is replaced on multiple belt drives, the newly replaced belt may be tight enough, but the remaining old belts will be too loose, and most of the power may be loaded by this new belt, causing the new belt to be damaged prematurely .
10. Tighten the center distance of the transmission device, turn the driving pulley a few times by hand, and use a belt tension meter to check whether the tension is proper.
11. Tighten the assembly bolts of the motor according to the specified torque.
12. Replace the protective cover.
13. It is recommended to adopt a trial run procedure. This procedure is to start the transmission, run under full load and then stop, check and adjust the tension to the recommended value. The operation of the belt under full load can make the belt and the wheel groove completely coincide. If it is possible to run the belt for 24 hours, it should run for at least one hour. The trial run program can reduce the number of tension adjustments in the future.
14. During the trial operation, the operating conditions should be closely monitored to see if there is abnormal vibration and listen carefully for abnormal noise. It is best to turn off the machine after running for a period of time and check the heating condition of the bearing and motor. If it feels too hot to the touch, the belt may be too tight, the bearing may be asymmetrical, or the lubrication may be incorrect.
15. For the timing belt, the slack is very small during operation, so it is generally not necessary to re-adjust the tension, but we still recommend starting the device and observing the performance to see if there is abnormal vibration and listen carefully for abnormal noise. It is best to turn off the machine after running for a period of time and check the heating condition of the bearing and motor. If it feels too hot to the touch, the belt may be too tight, the bearing may be asymmetrical, or the lubrication may be incorrect.
