The gear teeth cannot be turned with less than 17 teeth?
2019-11-14
In fact, the nature of things is like this. Under normal circumstances, gear teeth with fewer than 17 teeth will undercut (when the intersection of the tooth tip of the gear and the meshing line exceeds the limit meshing point of the gear to be cut, the gradual change of the root of the gear to be cut) Part of the tooth profile is cut off), which does not mean that it cannot be rotated.Once undercutting occurs, the thickness of the tooth root will become thinner, the gear's ability to resist bending will decrease, and the smoothness of operation will deteriorate.
