4.1.2 Chain links
The chain is composed of chain links. There are two types of chain links: inner links and outer links. 4.1.3 The type of locking parts
is recommended to be overhead.
4.2 Basic parameters
The specifications and basic parameters of the chain should comply with the regulations of installation 1. See Figure 1 for the size parameter code. Table 1

Prepare
The length of the working section is limited as follows: that is, the normal line of the tooth profile passing through the end of the length of the working section should pass within the center point of the adjacent tooth slot. The tooth shape of the working section can be. It is convex or linear, but it should be smoothly connected with the tooth groove arc and tooth arc.
