Difference between single-pitch roller chains and double-pitch roller chains

Roller Chain is used for shafting transmission of textile, agricultural machinery, lifting and transportation, engineering, mining, light industry, chemical industry and other machinery. It is suitable for high temperature, humid and dusty working conditions, not suitable for high speed, severe impact load and transmission of axial force. The chain coupling should work under good lubrication and protective cover.

1. The standard drive roller chain is a universal drive roller chain based on JIS and ANSI standards.

2. The plate chain is a hanging chain composed of a chain plate and a pin.

3. The stainless steel chain is a stainless steel chain that can be used in special environments such as medicine, water and high temperature.

4, anti-rust chain is a nickel-plated chain.

5. The standard accessory chain is a chain with additional accessories on the standard roller chain for transmission.

6. Hollow pin chain is a chain connected by hollow pins, according to customer requirements, you can freely add or remove accessories such as pins, crossbars.

7. Double-pitch roller chain (type A) is a double-pitch chain based on JIS and ANSI standards. Low-speed Transmission Chain with average weight and light weight, suitable for installations with long distances between shafts

8. Double-pitch roller chain (C type) is a double-pitch chain based on JIS and ANSI standards. It is mainly used for low-speed transmission and handling.It has standard diameter S-type rollers and large diameter R-type rollers.

9. Double-pitch attachment roller chain is a chain with attachments attached to the double-pitch roller chain. It is mainly used for transportation.

10. ISO-B type roller chain is based on ISO606-B roller chain. Products imported from Britain, France, Germany and other places use this type.

The roller chain coupling uses a common chain and meshes with two parallel sprocket wheels with the same number of teeth. The main difference between different types of chain couplings is the use of different chains. Common double-row roller chain coupling , Single-row roller chain coupling, toothed chain coupling, nylon chain coupling, etc. The chain coupling has a simple structure (composed of four pieces), is easy to assemble and disassemble, and does not need to move the two connected shafts during disassembly. It is compact in size, light in weight, has a certain compensation ability, does not require high installation accuracy, is reliable, and has a long life Longer and lower cost.
