1. The chain is cleaned before measurement
2. Wrap the tested chain around the two sprockets, and the upper and lower sides of the tested chain should be supported
3. The chain before measurement should stay for 1 min under the state of applying one-third of the minimum ultimate tensile load
4. When measuring, apply the specified measuring load on the chain, so that the upper and lower chains are tensioned. The chain and the sprocket should ensure normal toothing
5. Measure the distance between the centers of the two sprockets 1. In order to remove the clearance of the entire chain, it should be measured under a certain degree of tension on the chain
2. When measuring, in order to minimize the error, measure at 6-10 knots (link)
3. Measure the inner L1 and outer L2 dimensions between the number of rollers to obtain the judgment size L=(L1+L2)/2
4. Find the elongation length of the chain, this value is compared with the use limit value of the chain elongation in the previous item
Elongation of the chain = judgment size – reference length / reference length * 100%
Reference length = chain pitch * number of links The standard transmission roller chain is a general-purpose transmission roller chain based on JIS and ANSI standards. 2. The leaf chain is a hanging chain composed of chain plates and pin shafts. 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. The anti-rust chain is a chain with nickel plating on the surface. 5. The standard accessory chain is a chain with additional accessories on the standard roller chain for transmission. 6. The hollow pin shaft chain is a chain connected by a hollow pin shaft. According to the requirements of customers, the pin shaft, cross bar and other accessories can be freely added or removed. 7. Double-pitch roller chain (type A) is a chain with twice the pitch of the standard roller chain based on JIS and ANSI standards.It is a low-speed transmission chain with an average length and a relatively light weight, and is suitable for installations with long distances between shafts. distance chain. , mainly used for low-speed transmission and handling, with standard diameter S-type rollers and large-diameter R-type rollers. transport. 10. ISO-B type roller chain is a roller chain based on ISO606-B. Many products imported from Britain, France, Germany and other places use this type.
