Abstract

890,116. Toothed gearing. ZAHNSCHNEIDEMASCHINENFABRIK MODUL VEB. April 21, 1958, No. 12622/58. Class 80 (1). [Also in Group XXII] In a drive for a hobbing machine table, wherein a two-speed gearing 8-11, driven from a motor (not shown) through bevel gears 5, 6, provides a slow speed, hobbing drive through spur gears 10, 11 and a faster speed, shaving or true-running testing drive through spur gears 8, 9, the slow speed drive is imparted to the table through a first path comprising parallel trains each comprising bevel gears 13, 14, spur gears 16, 17, a worm 19 and a table-mounted worm-wheel 2 and the faster speed drive is imparted through a second path comprising the bevel gears 13, 14, spur gears 20-24, a clutch 26, bevel gears 27, a spur pinion 28 and a table-mounted spur-wheel 3, the ratio directly between the worms and worm-wheel 19, 2 being equal to that indirectly between said worms and worm-wheel via the spur gears 17, 16 and the second path gearing 20-28, and means are provided to remove axial restraint from the worms 19 when the clutch 26 is engaged to utilize the second path drive, so that the worms may idle in mesh with the worm-wheel. Wormshafts 18 are axially located by bushes 32 secured thereto engaging at each end abutment members 31 screwed into bearing sleeves 30, the extent to which the abutment members 31 are screwed out of the sleeves 30 determining the degree of axial freedom of the worms. The spur gears 16 are sufficiently broad for the spur gears 17 to remain in mesh therewith during axial movement of the worm-shafts 18. In operation, for the slow speed drive, the clutch 26 is disengaged, the abutment members 31 are screwed into the sleeves 30 to retain the worm-shafts 18 without axial play and the spur gears 10, 11 of the two-speed gearing are engaged for drive through the first path gearing 19, 2, the second path gearing 20-28 idling. For the faster speed drive, the members 31 are screwed out of the sleeves 30 to remove axial restraint from the worm-shafts 18, the spur gears 8, 9 of the two speed gearing are engaged and the clutch 26 is engaged, whereupon the worms are axially screwed until the tooth flanks of the pinion 28 and the spur-wheel 3 drivingly engage for drive through the second path gearing 20-28.
