Difference between Poly-V Belt And Synchronous Belt

Transmission mode and application scenarios

The main difference between poly-V belt and synchronous belt lies in the transmission mode and application scenarios. ‌Poly-V belt relies on the friction between the belt and the pulley to transmit power, which is suitable for occasions with large power transmission and compact structure requirements; while synchronous belt transmits power through the meshing of the teeth on the belt and the pulley, which is suitable for occasions requiring high-precision transmission.

The characteristics of poly-V belt include:

High transmission power: Poly-V belt has large friction and transmission capacity, which is suitable for occasions where high power is transmitted.

Compact structure: The belt body of poly-V belt is thin and soft, and can work on smaller pulleys, making the transmission system compact.

Smooth transmission: Poly-V belt has small vibration, fast heat dissipation, and smooth operation, which is suitable for high-speed and heavy-load occasions.

The characteristics of synchronous belt include:

High-precision transmission: Synchronous belt transmits power through the meshing of the teeth on the belt and the pulley, which has the characteristics of high precision and high efficiency.

High efficiency: The transmission efficiency of synchronous belt can reach 98%, which is suitable for occasions with high-precision transmission.

‌Low maintenance‌: Synchronous belts do not require lubrication, have low maintenance costs, and are suitable for various precision machinery.

Poly-V belts are suitable for occasions that require high power transmission and compact structure, such as automobiles, fitness equipment, etc.; while synchronous belts are suitable for occasions that require high-precision transmission, such as textiles, machine tools, tobacco, communication cables, etc.
