Cause and solution of multi-ribbed belt Faults

Cause and solution of multi-ribbed belt Faults

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

Give moderate tension

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
