The national standard in our country isGB/T10855-2003 "Gear chains and sprockets".

With the continuous development of high-speed chain transmission technology, new types of automobiles and motorcycle engines are increasingly using toothed chains. At high speeds, using toothed chains has obvious advantages over using roller chains and toothed belts. However, due to the existence of“Variable effects”Reduce instantaneous meshing impact and alleviate the transmission process“Multilateral effect”A new type of toothed chain that reduces instantaneous meshing impact, reduces wear, and lowers noise. Variable pitch toothed chain, also known asHVThe silent toothed chain adopts a rolling pin toothed mechanism for its hinge mechanism, which usually consists of two main components: the chain plate and the rolling pin. Together with the involute sprocket, they form the chain transmission device. fromHVStarting from the dynamic working process of the toothed chain. demonstratedHVThe principle of variable pitch for toothed chains. The meshing characteristics were studiedHVThe determination of the indexing circle of the toothed chain wheel and the tooth profile and processing of the chain wheel, in order to provide reference for the theoretical research and production application of variable pitch toothed chain transmission.

Characteristics of variable pitch toothed chain wheel
1,The working tooth profile of the sprocket teeth adopts involute.
2, HVChain wheel is a variable gear with a large negative displacement
3,Similar to involute gears,HVThe sprocket has a reference tooth profile. That is, its parameters are only related to the nominal pitchPof It has nothing to do with the number of teeth.
4, HVThe sprocket is a top cut type.
5, HVThe working tooth surface of the sprocket is hardened.
1, HVThe toothed chain drive is different from the standard toothed chain drive. There are three main components: chain plate rolling pin involute sprocket.
2, HVThe meshing process between a toothed chain and a sprocket is similar to the meshing process between gears and racks. The meshing process is smooth.
3,due toHVThe variable pitch effect of the toothed chain can minimize the lateral variation of the chain during meshing with the sprocket
4,The pitch circle diameter of the sprocket depends on the nominal pitch, rolling pin structure parameters, and the number of sprocket teeth. He is the basis for chain drive calculations
5, HVChain wheel is an involute gear with a large negative displacement. The magnitude of its displacement depends on the positioning dimensions of the sprocket and chain wheel.
6, HVThe reference tooth profile of the sprocket is only related to the nominal pitch. It is independent of the number of teeth

The Silent ChainKey Features:

(1)Noise small toothed chain(Often referred to as“Silent Chain”)It is transmitted through the involute meshing between the working chain plate and the sprocket teeth, so compared with roller chains and sleeve chains, the meshing noise is smaller.

(2)The high reliability is due to the multi piece structure of the chain links in the toothed chain,When individual links are damaged during operation, the entire chain does not immediately break, allowing people to detect and replace them in a timely manner. Meanwhile, compared with sleeve chains and roller chains with the same pitch, toothed chain transmission is more compact. To increase the load-bearing capacity, toothed chain transmission only needs to increase the size in the width direction, while sleeve chain and roller chain transmission require increasing the pitch of the chain or using multi row chains

(3)The high motion accuracy is due to the wear of the hinges in the straight roller chain, which gradually causes the actual pitch of the inner and outer sections to be different, and the pitch of the outer section becomes larger, thereby reducing the motion accuracy. The wear and elongation of each link in the toothed chain are relatively uniform, thus maintaining high motion accuracy.

According to the guidance, it can be divided into two types: toothed chain with inner guide and toothed chain with outer guide, and toothed chain with inner and outer composite Supporting gears

Classification of silent toothed chains:

1Silent toothed chain

2Hawa silent toothed chain

3Single axis silent toothed chain cylinder and flat shaft

4Silent toothed chain with internal and external contact and internal or external guidance

5Some silent toothed chains come with irregular blades

6The silent toothed chain has both straight back and curved back options

Silent conveying chains provide a smooth,durable,flat conveying surface that operates with less vibration and velocity variation than other conveying products. Chains are manufactured from hardened steel components,making them long lasting and tolerant of elevated temperatures. They are available in a variety of standard widths and constructions or can be easily buit to suit a specific application. Linked and pin with a special treatment ,So it has highly wearable and strength to pull and can provide more stable use effects and long usage life,all of the of these products as your demand.

The width of silent chain can from 50mm to 500mm.

Two pin silent chain can provide better use effects and longer usage life than single pin. And with protection plate can offer more safety protection for the product.The chain gear tooth chain Xiangjie: also called silent chain, the chain is a special heat treatment process, and solves the problem that the domestic heat
Do not pass the processing problem, chain plate adopts special steel chain forging and heat treatment, the thickness of 0.2mm, hard, soft, this
The treatment process, to solve the high hardness, hardness of small fragments. Processing, do not wear problems, the use of Zhou Qishou
Life greatly extended (under normal use 3-5 years) according to the central distance of two kinds: 12.7mm, 25.4mm.
Application: the tooth chain has generally matched with the ranks of machine, bottle conveying machine manufacturers.
Detection of the tooth chain: tooth chain we produce have been running for 24 hours in the bottle conveying machine, to be qualified, only

You can pack the factory.
Toothed chain is an important mechanical basis for a wide range of applications, mainly used in high speed, heavy load, low noise, large center distance conditions, the transmission performance is better than that of tooth belt, gear and roller drive, to become a large number of industries preferred form of transmission, can be divided into internal meshing gear the chain meshing form, outer meshing silent chain and the inner and outer meshing silent chain, the inside and outside the compound meshing noise minimum, is the most widely used.
Silent chain (gear chain drive) is an efficient, stable, drive economy. Its transmission speed and capacity are more than the chain belt and other types of silent chain. (toothed chain transmission) of low noise, small vibration, high transmission efficiency of more than 99%. The standard of silent chain chain and sprocket variety, so silent chain drive collocation is flexible, which can meet the different needs of different conditions
The chain shape of silent chain, in order to reduce the stress concentration degree, prolong the fatigue life, enhance the tensile strength of the chain. Stamping technology innovation bring pressure area each link can increase the bearing area. That links at reduced pressure, greatly reduce the chain in the process of using all stretched rate. The link is through shot blasting treatment to increase the fatigue strength, and surface consistent effect.
Silent chain and sprocket is designed to conform to the ASME standard profile using. RP series SC series with the transmission ability of silent chain two times, it can transmit more than 35 meters per second speed and more than 1800kW. When you need to load in the narrow space of high-speed transmission of high load when RP series of silent chain the transmission system is often the transmission type often used.
