    摘要: Enveloping worm threads with less than one revolution have on one side concave surface and on another side convex surface. This makes generation of concave and convex enveloping worm surfaces simultaneously and makes modification of surfaces by individual machining of each surface. Proposed method uses cutting edges that have rotation radius according with radius of curvature of machining surface. Another variation simultaneously cuts several threads, where enveloping worm blank has rotation around its own axis of rotation and relative motion to helical cutter around tooling axis. This reduces production cost and makes manufacturing easily.

    摘要: An improvement of a globoid worm gear generating method based on the "basic member gear theory" and the "secondary action theory" both proposed by the same inventors is disclosed. In one form, the surface of a globoid worm generating tool is defined as the tooth surface of an intermediate gear by a conical surface whose semivertical angle .UPSILON., 0.degree..ltoreq..UPSILON..ltoreq.90.degree.. In another form, the surfaces of a globoid worm gear generating tool are defined by two conical surfaces whose semivertical angles are equal and satisfy the above condition and whose major axes as well as bottoms are coincident with each other so that both tooth surfaces of a worm may be simultaneously generated.

    摘要: An apparatus for cutting an arcuately-shaped worm includes a support shaft adapted to carry a worm blank thereon and journalled in a frame which is mounted for pivotal movement about a fixed axis so that the worm blank may be simultaneously rotated on its axis and arcuately translated about the fixed axis relative to a cutter. The shaft is rotated by a drive means, and arcuate translation of the shaft is provided by a worm gear which is journalled in the frame and driven off the shaft, with the worm engaging a fixed gear segment, so the rate of rotation and of arcuate translation are coordinated.

    摘要: Provided is a method of making a barrel-shaped worm-like tool whereby a barrel-shaped worm-like tool capable of efficiently performing grinding without unequal wear can easily be made. The aforementioned method comprises making the barrel-shaped worm-like tool (12) by using a dressing gear (11) to dress the barrel-shaped worm-like tool (12), which is used for machining an internal gear and has a diameter that gradually increases from the ends (12b, 12c) to the center (12a) in the axial direction. On the basis of data wherein the number of teeth is less than that of the internal gear to be machined, the dressing gear (11) and the barrel-shaped worm-like tool (12) are engaged with each other at the same axial intersection angle as during gear-machining performed by the barrel-shaped worm-like tool (12).
