Gear wheel dimensioning and checking instrument has both radial and tangential feelers that can operate simultaneously in a high speed measurement mode or with only the tangential feeler for slower precise measurement

摘要

Gear wheel measurement instrument (1) has a support (5) for one or more gear wheels, a rotating positioning arrangement (7) for movement of the support and first (8) and second (12) feelers that work with radial (15) and tangential (23) positioning devices so that the feelers can be used for measuring the teeth flanks and tangential surfaces respectively.
