PU English name: Polyurethane referred to as PU, Chinese full name is polyurethane, which is a repeating carbamate group in the main chain.
A general term for macromolecular compounds of the group (NHCOO). It is made up of organic diisocyanates or polyisocyanates with dihydroxy or polyhydroxylated
The compound is added together. The core of the PU timing belt is generally galvanized steel wire, copper-plated steel wire, Kavra wire core, glass fiber core, etc.
PU glue layer. Divided into two types: single-sided toothed belt and double-sided toothed belt. The former is mainly used for single-axis transmission, and the latter is for multi-axis or reverse transmission.
It is another high-efficiency transmission belt that emerged in the world in 1980 and entered the Chinese market in 1990. The toothed belt is further divided into ladders according to the shape of the teeth
There are two types of teeth, which are shaped by a circular tooth, and the torque of the synchronous belt with a circular arc is the largest.
The PU timing belt is meshed with the tooth groove of the pulley to transmit motion and power. It is an meshing transmission and thus has gear transmission.
Various advantages of chain drive and flat belt drive. High wear resistance ensures that it still maintains good motion in the transmission. tolerance
Timing belt can also be added with PU, rubber (black glue, white glue, green glue, red glue), high temperature resistant rubber, high wear resistant rubber, various types
PVC conveyor belt, sponge (ordinary sponge, hardness sponge, cloth sponge), synchronous belt plus and minus cloth, drilling, milling and other deep processing.
