摘要： PURPOSE:To utilize for manufacturing a gear which is required to have a particularly high accuracy by a constitution wherein of motions to be given to a saddle sliding base, even if a quantity is small, a motion receiving an influence of a stick slip is generated smoothly without depending upon the sliding of a work saddle on the saddle sliding base. CONSTITUTION:The device consists of a bed 1, a saddle sliding base 2 and a work saddle 3, etc. of a gear cutting machine tool. Further, a gear to be machined 4 is supported by the saddle 3 through a work support 5 and a work table 6 on the saddle 3. Further, a tool 7 for performing a creation working of a gear 4 and a guide part 9 of a saddle 8 are installed on a tool saddle 8. Next thereto, the motion of the saddle 3 is given while leaf springs 13, 14 are being deflected and the motion of the saddle 3 is faithful to the shape of an operational surface 24 of a cam 20 and very flexible and smooth and a gear having an exact tooth trace (a gear for which a crowning working is applied) is obtained. With this, contribution can be made to a manufacture of a gear which is required to have a particularly high accuracy.

摘要： PURPOSE:To considerably simplify the construction of a power transmission system by performing the change-over operation of an electromagnetic clutch on a worm shaft on the basis of a change-over signal obtained from one of the cam shafts and rotating the other cam shaft. CONSTITUTION:At a completion of the work of lathe turning, a limit switch 61 is operated in accordance with the stop motion of a main spindle 11 to break an electromagnetic clutch 17 at the side of a lathe turning cam shaft 15. Simultaneously an electromagnetic clutch 18 at the side of a gear cutting cam shaft 16 is engaged, then the gear cutting cam shaft 16 is driven rotating instead of the lathe turning cam shaft 15 through a transmission system of clutch unit 22, belt 79, electromagnetic clutch 18, worm shaft 77 and the like. This driving motion causes the three of hob cutter spindle 25, main spindle 11 and trim spindle 50 to be synchronously rotated simultaneously the hob cutter spindle 25 is traversed to perform the machining work of prescribed hobbing.
