LANTERN GEAR MANUFACTURING DEVICE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: device has spindle 1 rigidly connected with carrier 2 of mechanism, which rolls workpiece relative to cutting tool formed as planetary gear mechanism. The latter has immovable sun gear 3 and satellite gears 4 and 5. Shafts of satellite gears 4 and 5 are disposed in carrier 2 and are adapted for carrying gears 6 and 7, which are engageable with gears 8 and 9, whose shafts are also disposed in carrier 2. Two clutches 10 and 11 disposed in carrier 2 have halves (12 and 13) connected with gears 8 and 9 and halves (14 and 15) mounted in carrier 2 so that their shafts may be biased relative to shafts of halves 12 and 13 by means of clamping screws 16 and 17. Satellite gears 4,5 and gears 6,7 may be replaced. Movable frame 18 fit onto insert of clutches 10 and 11 is rigidly connected with table 19 for workpieces. EFFECT: increased efficiency, simplified construction and wider operational capabilities. 1 dwg
