| PURPOSE:To improve working accuracy of the effective engaging portion of a rack with a pinion by disposing a relief groove for a finish machining tool along the root of the rack. CONSTITUTION:A rack material is molded to form a substantially V-shaped primary tooth surface 8 indicated by an imaginary line. The depth of the primary tooth surface 8 is larger than the grain depth of cut worked in a conventional way. Subsequently, a secondary tooth surface 9 is molded. The secondary tooth surface 9 presents a final tooth form and has an easier grade than the primary tooth surface 8, the grain depth of cut thereof being smaller than that of the primary tooth surface 8. Therefore, in the vicinity of the root, a square portion 10 is formed between the primary and secondary tooth surfaces 8, 9, and the bottom of the primary tooth surface 8 is a relief groove 11. In case of working near the bottom of the secondary tooth surface 9, the relief groove 11 keeps a cutting tool from contacting the primary tooth surface 8, which can reduce cutting resistance and improve working accuracy. | ||||||

| For machining a concave-convex gear in which concave teeth of the concave-convex gear and convex teeth of a mating gear are formed in a circumferential direction, to allow torque transmission to or from the mating gear, in a trajectory extracting step a relative movement trajectory of each convex tooth of the mating gear with respect to the concave-convex gear at the time when torque is transmitted is first extracted as a machining target. Then, in a machining step, the concave teeth of the concave-convex gear are machined on a disc-shaped workpiece by moving at least one of the disc-shaped workpiece and a working tool such that a relative movement trajectory of the working tool with respect to the disc-shaped workpiece coincides with the relative movement trajectory of each convex tooth of the mating gear with respect to the concave-convex gear extracted in the trajectory extracting step. | ||||||

| The invention relates to mechanical transmissions for transforming the rotational motion to the rotational or reciprocal one, applying the toothed engagement of gears and it can find its application in cylindrical, bevel or planetary gearboxes and rack gears. One of the engaging profiles represents the gearwheel with at least two helical teeth. Operating segments of each tooth flank of this gearwheel are outlined in principal cross-sections by arcs of the circumference, eccentrically shifted with respect to the center of the gearwheel rotation. Conjugating helical teeth of the second profile are outlined in the same cross-section by segments of cycloidal curves. Tips and troughs between teeth can have any shape, not intersecting with the gearwheel teeth. | ||||||

| In a method of milling at least one localized region of a workpiece the workpiece is rotated about a horizontal axis of a cylindrical region having a radius R.sub.p. An external contour of radius R.sub.F of a tool is brought into contact with the cylindrical region of the workpiece at a machining point. The tool rotates about a rotation axis intersecting a first transverse axis of the workpiece perpendicular to and intersecting the longitudinal axis. The rotation axis is in a plane parallel to the longitudinal axis and to a second transverse axis of the workpiece perpendicular to and intersecting the first transverse axis and to the longitudinal axis. The rotation axis is at an angle .alpha. to the second transverse axis such that the tangential speed of said tool parallel to said second transverse axis is equal to the tangential speed of said workpiece. | ||||||

| Continuous-curvature lobed cams, such as are variously used after the manner of gearing in orbital-drive mechanical transmissions, hydraulic motors and the like, are formed with the precise and continuous distinctive contouring which is essential to their successful operation by way of a simple and inexpensive cutting tool rotated about a fixed axis in a conventional machine while the cam blank with which it is in a material-removing engagement is both rotated relatively slowly in one angular direction and orbited relatively rapidly and synchronously along a circular path in the opposite angular direction. Synchronism between the slow rotary and rapid orbital motions is achieved in a machine-mounted fixture through geared drive of two rotary tables from a common motive source on the same movable platen which mounts the two rotary tables. One of the rotary tables orbits the platen along an adjustable-eccentricity path relative to the supporting machine bed, as accommodated by an X-Y mount, and the number of cam lobes to be fashioned is determined by introducing an appropriate gear in an adjustable gear train between the motive source and the other rotary table which rotates the cam blank. | ||||||
