The effective tensioned chain segment has at least 3 links, both ends of the chain segment are inner links, and the connection between the two ends of the chain segment and the chuck of the testing machine should ensure that no additional stress is generated on the chain parts. If the link connected to the chuck is damaged during the test, the test is invalid. The tested chain link cannot be used again.
2.3.2 Chain length accuracy
The chain length accuracy should be measured according to the following requirements: a) The chain should be cleaned before measurement:
b) The measured chain should be placed horizontally and supported in the measured chain segment; c) After applying the measuring load, measure the distance between the generatrix on the same side of the roller; d) The number of measured chain links should comply with the provisions of Table 2. The actual relative deviation value of the measured chain length should not exceed +825% Table 2

3.3 End face tooth groove corridor
JB/T9153-1999
The tooth groove profile of the sprocket is formed by the smooth connection of the top arc of the tooth profile, the working section and the tooth groove arc (see Figure 3 and Table 7). Figure

Calculation formula or explanation
The effective working part of the tooth, its length is calculated according to the formula w0.01p. The working section length is limited as follows: that is, the tooth profile normal at the outer end M of the working section length should pass within the adjacent tooth groove center point ○. The tooth profile in the working section is generally straight, or convex. The angle between the normal of the roller at the tooth surface contact point and the center line of the chain link is called the action angle, and its value is shown in Appendix A
Values ​​are shown in Appendix A
The axial tooth profile of the sprocket should comply with the provisions of Figure 4 and Table 8. 369
