| Installation & Maintenance |
| |
| 1. The correct installation of belt. |
| (1) |
Switch off the power, remove the protective cap. Loosen the assembly bolt. Move the motor to make the belt loose, you can take off the belt without prying the belt off is not allowed. |
| (2) |
Take off the old belt, then check if there is any abnormal wear and tear. Excessive wear and tear may indicate there are some problems with the design or maintenance of the gearing. |
| (3) |
Choose the proper belt for changing. |
| (4) |
Clean the belt and pulley, use a cloth with some liquid which can't volatilize easily to wipe. Soaking in the cleaning formulation or brush the belt with cleaning formulation are not good; use the sand paper or sharp subject to scratch are not proper. The belt must be dry before using. |
| (5) |
Check the pulley if there is any abnormal wear and tear or crack. If the wear and tear is excessive, the pulley must be changed. |
| (6) |
Check the pulley to see if it is symmetrical of straight line, which is very important for the performance of the transmission especially for the timing belt gearing. |
|
|
| (7) |
Check the rest parts of the gearing, for example, the symmetry of the bearing and the bearing boot, durability and lubrication, etc. |
| (8) |
When installing a new belt on the pulley, prying or using too much force is not allowed. |
| (9) |
Adjust and tighten the central distance of the gearing, until the tension is proper measured by the tension gauge. Use hand to rotate the driving pulley for several rounds and measures the tension again. |
| (10) |
Tighten the assembly bolt of the motor, correct the torque, because any change of the central distance will cause the bad property of the belt, when the gearing are tightened. |
| (11) |
Switch the gearing on and observe the property of the belt if there is any unusual vibration. Listen carefully to see if there are any unusual noises. You'd better turn off the machine, then check the condition of bearing and motor, if the temperature is very high, because the belt may be too tight or the bearing is not symmetrical, or the lubrication is not correct. |
| |
| 2. The maintenance of the belt and the pulley. |
| (1) |
The belt can't be crimped and bend sharply. |
| (2) |
During the process of the storage and the transportation, keep the belt and the pulley out of direct sunlight, not get wet from rain and snow, prevent it from touching the acid, alkali, organic, organic solvent and steam etc, which can influence property of the belt. |
| (3) |
Storage under the usual temperature, from -20℃--50℃, and keep it away from heat source at least 1 meter. |
| (4) |
During the storage, it can't be piled up, for the weight might cause the change of the shape, and it can't be placed on the ground directly, it should be hanged on the shelf or put on the shelf. |
| (5) |
The finished pulley should be stored and transported under a dry and ventilated environment, and the anti-rust processing is also needed. |
| (6) |
The belt gearing should have a protective cap, and the discharge of the pollution and ventilation must be assured. |
