What is it
Toothed chain, also known as silent chain, belongs to a form of transmission chain. The national standard of our country is GB / t10855-2003 toothed chain and sprocket. The toothed chain is composed of a series of chain plates and guide plates alternately assembled and connected by pin shafts or combined hinged elements, and the adjacent pitches are hinged joints. According to the guide type, it can be divided into external guide chain, internal guide chain and double internal guide chain.
The noise is very low
The tooth chain is meshed with the involute tooth profile of the sprocket through the working chain plate.
High reliability
When some of the chain pieces are damaged in the work, the whole chain will not be broken immediately.
The motion precision is high
Due to the wear of the hinge, the actual pitch of the inner section and the outer section is gradually different, and the outer section pitch becomes larger and larger, thus reducing the transmission accuracy.
Characteristic
The noise is very low
The tooth chain is meshed with the involute tooth profile of the sprocket through the working chain plate. Therefore, compared with roller chain and sleeve chain, meshing noise is smaller.
High reliability
This is because the chain link of the toothed chain is a multi piece structure. When individual chain segments are damaged in the work, the whole chain will not be broken immediately, which can make people discover and replace them in time. At the same time. Compared with the sleeve chain and roller chain with the same pitch, the gear chain transmission is more compact. If the load-carrying capacity needs to be increased, the gear chain transmission only needs to increase the smaller size in the width direction, while the sleeve chain transmission needs to increase the pitch of the chain or adopt multi row chain.
The motion precision is high
This is because in the straight plate roller chain, due to the wear of the hinge, the actual pitch of the inner section and the outer section is gradually different, and the outer section pitch becomes larger and larger, thus reducing the transmission accuracy. However, the elongation of each link of the toothed chain is uniform due to wear, so it maintains a high movement accuracy.
Classification
Shape
The products and specifications of toothed chain are various, and the application field is very wide. Generally speaking, the toothed chain can be divided into two categories according to the different pin shape: round pin toothed chain and roll pin toothed chain (often called “HY VO toothed chain”) .
Different forms
At the same time, according to the different forms of transmission. It can be divided into single-phase drive chain, double-phase drive chain and multi-phase drive chain
direction
According to the different meshing direction, it can be divided into single-sided meshing chain and double-sided meshing chain.
application area
Toothed chain is an important basic mechanical part widely used. In recent years, various kinds of toothed chains have been widely used in automobile engines, transmissions, transfer cases, motorcycles, forklifts, steam turbines, airplanes, ships, steel rolling machinery, machine tools, industrial pumps and other high-speed drives. With the continuous development of high-speed chain transmission technology, new types of toothed chains, which are suitable for the “personalized” needs of the main engine, have been widely used A series of high-speed tooth chain products with different meshing mechanisms have come out in developed countries and entered the domestic market.

Chain
When the sprocket teeth are involute, the roll pin chain is often referred to as hy VO chain. Due to the variable pitch function of hy VO chain, the polygon effect in the chain transmission process is significantly reduced, and the impact and vibration are reduced. Therefore, hy VO chain is often used as the transmission device under the working conditions of high speed, heavy load and large center distance, such as oil drilling rig, metallurgical machinery, chemical machinery, generator set, etc.
