Advantages of Poly V-belts and Fault Analysis of V-belt
The Poly-V belt is a single, endless belt with longitudinal V-shaped ribs that mate consistently with the V-grooves in the sheaves. It combines the convenience of a thin, one-piece flat belt with the strong gripping traction of multiple V-belts to make the Poly-V belt far better than either for many applications.
Poly-V belts have triangular section longitudinal ribs. Thanks to the reduced thickness, these belts are very flexible and can be wind up on very small diameters. Poly-V belts can achieve higher peripheral speed than V-belts.

Fault Analysis of V-Belts
| Fault | reason | Solution |
| Belt slip | – The number of roots is small – The diameter of the belt wheel is too small – The wrap Angle is too small – The band tension is too small – Tape with oil or water – Excessive load | -Increase the number of strips – Properly increase the diameter of the pulley -Set the guide wheel or change the transmission to increase the wrap angle – Appropriately increase the pulling force -Remove oil stains and dry the water – Redesign according to maximum load |
| Belt hardening | – Belt body heats up due to slippage – Ambient temperature is too high | -Change the belt tension to fit -Improve heat dissipation method or choose heat-resistant belt |
| Abnormal noise | -The belt tension is too small – Start or stop sharply | – Appropriately increase the pulling force -Extended start or stop time for smooth transmission |
| Large vibration | – The center distance of the belt wheel is too large – The band tension is too small – The belt length is inconsistent when multiple belts are driven Large load variation | – Set the guide wheel – Increase the tension appropriately – Use matching belts |
| Band bottom damaged | – Improper selection of pulley diameter or belt type – Belt body is stained with dust or chemicals – Belt slip – The diameter of the back pinch roller of the belt is too small or the tension is too large | -Choose the appropriate asterisk and pulley diameter -Install the protective cover for the belt -Change the belt tension to fit – Properly increase the diameter of the pinch roller or install it on the inside of the belt to change the bending direction |
A good V-belt cannot be separated from a professional company. ZZR is a belt manufacturer that deserves its name by its quality and service. It has a strong market supply chain around the world, specializing in providing high-quality belt products for major enterprises and fields.
