Fan Belt Vs Timing Belt

The main difference between poly-V belts and synchronous belts lies in their transmission methods and application scenarios. ‌

Poly-V belts‌

Features: Poly-V belts combine the advantages of flat belts and V-belts (V-belts), and have the characteristics of large transmission power, small vibration and smooth operation. It is suitable for occasions where the power transmission is large and the structure requires compactness. The transmission ratio can reach 10 and the belt speed can reach 40m/s. Poly-V belts have various types and structures, including PJ, PL, PM, etc., with the characteristics of large transmission capacity, elimination of uneven belt length, small elongation and long service life. ‌

Application areas: Poly-V belts are widely used in the transmission fields of textile machinery, printing and dyeing machinery, airport logistics machinery, tobacco machinery, sports machinery, woodworking machinery, food machinery, automobile manufacturing machinery, ceramic machinery, stone processing machinery, paper printing machinery, electronic machinery, glass deep processing machinery, hardware processing machinery, wire and cable and other industries. ‌

Synchronous belts‌

Features: Synchronous belt transmission is a meshing transmission with the characteristics of high precision and high speed, suitable for use in high-precision instrument devices. The advantages of synchronous belt transmission include smooth operation, low noise, low vibration, and low requirements for manufacturing and installation precision.

Application scenarios: Synchronous belts are mainly used in situations requiring high precision and high speed, such as precision instruments, automation equipment, etc. Some special types of synchronous belts can also withstand large loads and high-speed operation.

In summary, poly-V belts perform well in situations requiring high power transmission and space restrictions with their high transmission power and compact structure, while synchronous belts occupy an important position in precision equipment and automation systems with their high precision and high speed characteristics.
