摘要： PROBLEM TO BE SOLVED: To make a face gear rotate smoothly. SOLUTION: A face gear 11 is formed in a disc shape and the periphery of a flat area 13 thereof is provided with a gear cutting part 14, which is protruding from the flat area 13, so that it may extend in an annulus ring shape. The gear cutting part 14 is provided with a plurality of meshing teeth 15 in the circumferential direction, while respective meshing teeth 15 extend in parallel to the flat area 14 and respectively incline in an equiangular degree to the outer circumference of the face gear 11. The meshing teeth 15 are curved so that they may be in a protruded shape toward the arrow mark W direction. Inclined tooth gears 64 fitted to an output shaft 63 of an electric motor mesh with meshing teeth 15 of the face gear 11. Under this situation, three meshing teeth 65 of the inclined tooth gears 64 respectively contact with three meshing gears 15 of the face gear 11. When the electric motor is driven and the output shaft 63 is rotated so that its axis may become the center, the three meshing gears 15, 65 mutually contact each other at respectively different positions at all times.

摘要： A machining apparatus for making the scroll parts comprising a headstock including a spindle for supporting a workpiece for rotation, a tool holder for supporting a machining tool, a first carriage supported for movement in a direction perpendicular to the spindle (an X-axis), a second carriage supported for movement in a direction parallel to the spindle, and a control device for controlling the movement of the first carriage and the rotation of the spindle according. The control device is so programmed as to calculate the distance between the center of the base circle generating a desired involute curve depicted by the scroll parts and the center of the machining tool and also to calculate the angle of rotation C of the spindle relative to the distance.
