How to measure short pitch roller chain? The basic requirements for the performance of short pitch roller chain data are generally high strength and good wear resistance, and the conveyor chain is no exception. However, compared with the transmission chain, the transmission chain speed is slow and the load is large, and the total length of the chain used is long and the number of chain links is large, so the quality of the chain is large. Especially for the large roller conveyor chain, because the quality of the large roller accounts for a larger proportion in the chain, the problem of short pitch roller chain mass is more prominent. A chain with too much mass will greatly increase the tension accepted by the chain, thus increasing the consumption of ineffective power.

1. In order to remove all the gap of the chain, it is necessary to measure under a certain level of pulling tension on the chain

2. When measuring, in order to reduce the error as much as possible, measure at the local area of 6-10 (link)

3. Measure the inner L1 and outer L2 scales between the rollers of the pitch number to find the discriminating scale L=(L1L2)/2

4. Find the extension length of the chain, and this value is compared with the operating boundary value of the chain extension in the preceding item.

Therefore, reducing the quality of the conveyor chain itself is an important issue in the design of the conveyor chain. short pitch roller chain manufacturers have made great progress in using engineering plastics to make chains. The engineering plastic is used to make the conveyor chain parts, which only reduces the weight, and has the advantages of reducing friction, noise and no grease smooth. At present, the strength of engineering plastics is still low, and the stainless steel transmission chain can only be used to make the chain of a small conveyor, as well as the roller on the attachment of the lighter conveyor chain.
