3.Common V-belt is in accordance with related international standard. 4. high wearing resistance, low elongation and long life.



Using:Classical V-belt is used widely in power transmission of mechanical equipments driven by electric motors and diesel engines.

v belt Structure:
Vee belt is made up of wrapping layer , stretching layer , strength layer and compression layer . it has excellent features of heat-resistance . wear proof , ageing- resistance and fatigue resistance , Shielding cloth: it is made of the special cotton canvas which ensures the belt to be elongation resistant and wearable, making the surface layer tougher. Buffered rubber: the rubber with good performance, high wearing resistance. Low compress and distortion, which keeps the belt in normal shape during operation and protects the elongation resistant part (reinforce) in the belt. Elongation resistant part (reinforce): the main part contributes to high strength of the belt, It is composed of polyester threads with high elongation resistance etc.

Store And Transport

1.In storage and transportation of V-belt ,direct sunshine as well as the soaking of rain of rain and snow should be kept clean and the contact with acid,alkali,oil and organic solutions should be prevented.Cares should be taken to prevent mechanical damage.And,the belt should be 1 Km away from heat radiation devices.

2.The storage temperature should be -18--+40.

3.In storage,the belt should no be under heavy pressure so as to prevent deformation.The best method is to hang the belt on a crescent frame or put it on the shelt flatly.

4.The performance will be kept unchanged in one year when the belt is in storage under the above condition.
