1. Fastening Principle
The inner diameter of Belt Sprockets and the outer diameter of the sleeve are tapered, and by tightening the clamping nut,
Belt Sprockets move by sliding on tapered surfaces.
At this time, a wedge action generates forces P and P' that press against the shaft and the inner surface of the tapered surface.
This P and P' force generates a frictional force that tightly fastens Belt Sprockets and shaft together.
