Abstract

A scanner head for a tooth-flank scanning device for testing and measuring of gears and similar parts, in particular of gearlike tools having abrasive tooth flanks, is adapted to be introduced into a tooth space of the respective gear or similar part and which can be guided along one of the tooth flanks bordering the tooth space. The scanning piece or insert is formed by the convex surface of a spherical segment, the radius of which is substantially greater than the radius of a ball introducible into the tooth space.
