Toothed chain, also known as Silent Chain, is a form of transmission chain. my country’s national standard is: GB/T10855-2003 “Toothed Chains and Sprockets”. The tooth chain is composed of a series of tooth chain plates and guide plates that are assembled alternately and connected by pins or combined hinge elements. The adjacent pitches are hinge joints. According to the guide type, it can be divided into: external guide tooth chain, internal guide tooth chain and double internal guide tooth chain.
main feature:
1. The low-noise toothed chain transmits power through the meshing of the working chain plate and the involute tooth shape of the sprocket teeth. Compared with the roller chain and sleeve chain, its polygonal effect is significantly reduced, the impact is small, the movement is smooth, and the meshing is Less noise.
2. The links of the toothed chain with high reliability are multi-piece structures. When individual links are damaged during work, it does not affect the work of the entire chain, allowing people to find and replace them in time. If additional links are needed, The load-bearing capacity only requires smaller dimensions in the width direction (increasing the number of chain link rows).
3. High movement precision: Each link of the toothed chain wears and elongates evenly, which can maintain high movement precision.
The so-called silent chain is a toothed chain, also called a tank chain. It looks a bit like a chain rail. It is made of multiple pieces of steel riveted together. No matter how well it meshes with the sprocket, it will make less noise when entering the teeth and is more resistant to stretching. Effectively reducing chain noise, more and more timing chains and oil pump chains of chain-type engines now use this silent chain. The main application scope of toothed chains: toothed chains are mainly used in textile machinery, centerless grinders, and conveyor belt machinery and equipment.
Types of toothed chains: CL06, CL08, CL10, CL12, CL16, CL20. According to the guide, it can be divided into: internally guided toothed chain, externally guided toothed chain, and internally and externally compounded toothed chain.
