If the belt has a 2MM difference, will it affect the use?

Can 6PK2155 replace 2160? Can 8PK1060 replace 1062? The customer asks like this ,I want to say that it can be replaced.

In fact, many models with similar lengths are usually made by the same mold, For example: 6PK1062 and 6PK1060, the factory uses the same mold for production.Because each of our molds differs by 5mm, if you need 6PK1016, then we will use 6PK1015 molds to produce. 

In addition, the belt pulley can adjust the distance , so the tolerance of the belt length will not affect the normal use of the machine.

Cause and solution of multi-ribbed belt Faults  

Malfunctions during mechanical use are very tricky.When troubleshooting belt faults, in addition to replacing new products, finding the cause of the fault and mastering the correct use method can give full play to the performance of the belt and prolong its service life.



The following table introduction the representative phenomena of belts. Please refer to the countermeasures in the table below when a malfunction occurs.

 





Fault


Cause


Solution




Slippage


Belt tension slack


Give moderate tension




overload


Widen the belt or increase the number of belts




Small contact angle


Widen the belt or place the correct diameter idler pulley




Stained with oil or water


Thoroughly remove oil or water. Install belt cover to prevent oil and water adhesion




Premature rupture


Load changes / suddenly overloaded . The transmission conditions used exceed the transmission capacity of the belt. Failed to hang belts in accordance with the required number of belts; not using the specified belt shape.
           


The design can be changed, but the hanging belt must be the specified belt shape and number (please use a higher-level belt according to the use)




Increase heat or excessive bending fatigue use(the diameter of the pulley is too small, the bending angle is too small, and the speed is too fast)


Take measures to reduce heat;

Change the design — change the pulley diameter, rotation speed, and bending angle     




Tension becomes loose and slips off


Give moderate tension




Cracked


Use at high temperature


Take exothermic measures




Tension becomes loose and slips off


Give moderate tension




Continuous emergency stop or emergency start


Change design




Stained with oil, etc.


Avoid oil adhesion and oil leakage




The pulley diameter is too small, and the back tension causes the reverse bending to be too strong


Change design




Direct sunlight


Attach the machine belt cover




Surface cracking


Tension pulley diameter is too small


Use a larger diameter tension pulley




The bending angle is too small


Relax the bending width




Tension becomes loose and slips off


Give moderate tension




Abrasion


The pulley groove is rusty or the surface of the pulley groove is rough


Evenly process the groove surface of the pulley




Tension pulley diameter is too small


Use a larger diameter tension pulley




The angle of the pulley device is incorrect; the shape of the pulley is abnormal, and the angle of the pulley groove is not accurate


Adjust the dislocation to below 1/3° , replace the pulley




Excessive vibration


The device of the machine body is unstable and resonates


Fix the device part




The belt tension is weak


Change the distance between axes




Belt length is not uniform


Use a consistent belt combination




Peel off


The transmission conditions used exceed the capacity of the belt


Hang the belt with the correct size, shape and number




Used in a deformed state, the method of use causes increased bending fatigue


Change design




Make strange noises


Emergency stop or emergency start


Change the design to make the belt run smoothly




Belt tension is too loose


Give moderate tension




overload


Widen the belt or increase the number of ribbed used




Machine belt choose error


Choose the belt shape and specifications that meet the operating conditions




ribbed belt flip


Not suitable for pulley groove angle and device angle


Dislocation aligned to the 1/3°or less




Adhesion of the machine belt due to damage to the pulley groove or rough processing surface


Replace the pulley




The belt length is not uniform when using multiple belts


Use a consistent belt combination
