Description
The installation and maintenance of belt
1.Switch off the power,remove the protective cap.loosen the assembly,move the motor to make the belt loose,you can take off the belt wrenching it up.
2.Take off the old belt,and then check if there is any abnormalwear 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.
4.Clean the belt and the pulley using a cloth with some liquid which can't volatilize easily.It is not proper to soak it in the cleaning formulation or brush it with cleaning formulation or use the sand paper or sharp subject to scratch.The belt must be kept in dry condition.
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 ifit is in symmetrical 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 nstaling a new belt on the pully,it is forbidden to wrench or use too much force.
9.Ajdust 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 nay change of the central distance well cause the bad property of the belt.Make sure all the gearings are tightened.
11.Switch the gearing on and observe the property of the belt if there is any unuaual 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,may be because the belt is too tight or bearing is not symmetrical,or the lubrication is not correct.

Problem analysis | Edge wear | |||
Problem and analysis | Solution | Belt not parallel to axis:Belt runs against flanged pully | Check drive,line up or, ifnecessary,replace any nonaligned pulleys change the belt | |
Running noises froom belt | Adjust tension properly | Wheels axially off-centre:Timing belt cannot be properly aligned | ||
Tension too high:Belt whines,whistles | Flang pulley has flaws | Replace pulleys.change the belt | ||
Tension too low:Belt knocks against covering | Bearing play in components | |||
Fabric wear in the tooth foot | Fabric wear in the tooth foot | |||
Belt excessively tensioned | Change the belt,adjust tension correctly | Belt excessively tensioned | Change the belt,adjust tension correctly | |
Belt is overheating | Find out cause (e.gcheck cold performance),take corrective actioon,change the belt | Belt is overheating | Find out cause (e.gcheck cold performance),take corrective actioon,change the belt | |
Timing belt pulley is worn out | Replace timing belt pullley,change the belt | Timing belt pulley is worn out | Replace timing belt pullley,change the belt | |
Teeth and fabric separating from belt body | Running marks on teeth side | |||
Leaks(e.g.escape of oil,antifreeze etc | Repair leaks,chang the belt | Foreign matter in timing belt dive | Remove foreign matter,check the belt,check the cover is seated properly | |
Flaws in teeth of timing belt pulley cause by foreign matter of tools during mounting | Replace timing belt pullley,change the belt,ensuring it is properly mounted | |||
Timinng belt damaged before/during mounting | Change the belt ensuring it is properly mounted | |||
Crack on back of timing belt | Crack on back of timing belt | |||
Ambient temperature too high/low | Find out cause (e.g.check cold performance),take corrective actioon,change the belt | Ambient temperature too high/low | Find out cause (e.g.check cold performance),take corrective actioon,change the belt | |
Contact with foreign media | Change the belt ,chcek the covering is seated properly | Contact with foreign media | Change the belt ,chcek the covering is seated properly | |
