Synchronous pulley:Widely used in mechanical, textile, printing, tobacco, chemical, light industry, metallurgy, mining, instrumentation, petroleum, automotive and other industries. Our company can design and manufacture synchronous pulleys for various purposes for users, with reasonable prices and timely delivery. We welcome cooperation.
Multi wedge pulley:Multi wedge belt transmission is a comprehensive transmission of V-belts and flat belts, with advantages such as high transmission power, good twisting performance, long service life, low energy loss, and low elongation. It will gradually replace V-belts, flat belts, and other fields.

Type of Basic Structure of Synchronous Pulley
P=Pitch is the distance between the axes of two adjacent teeth irespecive of whether these teeth are on the pulley or the belt provided that measurement is taken on the circum ference of pitch line
Z=Nunber of pulley teeth
Dp=The diameter of the pulley pitch is obtained from fomula Dp=P.Z/π
De=External diameter of pulley De=Dp-2k
Dm=Hubs diameter
d=Bore diameter
W=Tooth width
L=Total lenght incl hubs
Synchronous pulley materials:steel,cast piece,aluminium alloy
