Hirth tooth system

Function
With Hirth tooth systems, positions of rotation on a rotary axis are usually interlocked using a
latch or other toothed wheel via a linear axis. The interlock should only be activated when an
indexing position has been reached precisely. The distance between the indexing positions
is the same (equidistant) across the entire circumference.
