Product Description

Toothed chain, also known as silent chain, is a form of transmission chain. China's national standard is GB/T10855-2003 Toothed Chain and Sprocket. Toothed chain is composed of a series of toothed chain plates and guide plates alternately assembled and connected by pin or combined hinge elements, and the adjacent pitch is hinge joint. According to the guide type, it can be divided into external guided toothed chain, internal guided toothed chain and double internal guided toothed chain.

Main features:

1. The noise small tooth chain transmits power through the meshing of the involute tooth profile of the working
chain plate and the sprocket teeth. Compared with the roller chain and sleeve chain, the polygonal effect is significantly
reduced, and the impact is small, the movement is stable, and the meshing noise is small.

2. The chain link of the tooth chainwith high reliability is a multi-piece structure. When a single chain link is damaged in the work, it will not affect the work of the whole chain, so that people can find and replace it in time. If it is necessary to increase the bearing capacity, it only needs to be smaller in the width direction (increase the number of chain link rows).

3. High kinematic accuracy The wear and elongation of each link of the toothed chain are uniform, which can maintain high kinematic accuracy. The so-called silent chain is a toothed chain, also known as a tank chain. It looks like a chain track. It is riveted by multiple steel plates. The better the meshing with the sprocket, the less noise when entering the teeth, the more resistant to stretching, and can effectively reduce the noise of the chain. Now more and more chain engines use this silent chain for timing chain and oil pump chain.

Main application scope of toothed chain: toothed chain is mainly used in textile machinery, centerless grinder and conveyor belt mechanical equipment.
