Abstract

1392862 Grinding gears WERKZEUGMASCHINENFABRIK OERLIKON - BUHRLE AG 20 Oct 1972 [21 Oct 1971] 48368/72 Heading B3K Apparatus for grinding bevel or hypoid gears comprises a grinding head 10 having a plurality of rotatable grinding wheels. Head 10 comprises a ring 15 screwed to a body 13, and the grinding wheels 12 are each radially and axially adjustably mounted in the ring by a holder 17. Outer grinding wheels 11 are each radially and axially adjustably mounted in the body 13 by a holder 22. A pair of grinding wheels 11, 12, pass through the tooth gap of the gear to be ground and are adjustably spaced from each other by an angle γ 1 . Holders 17, 22, are each radially adjusted by screws 18, 23, and fixed by screws 19, 24. Cam discs 29, 31, are adapted to adjust wheels 11, 12, in the axial direction; the wheels being secured by blade springs 21, 26. Each wheel 11, 12 is rotated about its axis by its own pneumatic motor 32. The grinding head 10 is rotated in either direction by a motor, through a V-belt drive 7AM, and an eight speed gear transmission A, B, C, and the workpiece is rotated by the same source through gearing A, D, and gears T 1 -T 4 . The gear is first cut on the machine of Fig. 3 with a cutter replacing the grinding head. The gear is then finish-ground using head 10. By using cam discs 29, 31, the teeth can be crowned.
