ABSTRACT:
This application discloses a work-holding chuck particularly for gears with their exterior teeth finished or substantially finished as by grinding, shaving and the like. This chuck has a plurality of hardened and finished pins which are moved and secured in a precise circular array and arranged as pairs on a ring member. A stop is provided so that the gear and the hub portion thereof is precisely located and positioned. Sliding segments are moved along a ramp guide by pneumatic or hydraulic means to bring the formed pins into the formed flanks of the teeth profile to repeatedly and precisely hold the gear by its formed and finished teeth. The held gear is now finished in its bore. Means are provided for readily changing the pins and position of these pins on the chuck so that gears of different pitch, number of teeth and/or lead may be accommodated.
