A CNC machine for producing spiral-toothed bevel gears is described, which has a first carriage supporting a tool spindle and is displaceable in height, and whose guide is disposed on a lateral surface of a machine housing, which is horizontally guided in a straight coordinate axis on a machine base. The tool spindle axis is parallel with the lateral surface and with the coordinate axis. Furthermore, the machine has a workpiece spindle support having a second carriage and a pivoting device with a vertical axis and is also horizontally guided on the machine base. The parallel arrangement of the tool spindle axis results in a new machine concept with a compact structure and optimal chip flow. Therefore the machine is particularly suited for heavy-duty dry milling. Since the tool spindle is not located above the area of the machine having a horizontal guide, it is possible to arrange a chip collector underneath the tool spindle, which can be reached by the chips essentially under the force of gravity.

Method of grinding the teeth of spiral-toothed bevel gear wheels

Method of finishing the hardened teeth of a bevel gear wheel

The invention relates to a method for producing continuous corrections on a bevel gear, whereby by entering a plurality of corrections into the CNC control of the machine and interpolation between them, camber designs and even the designs of twists or the avoidance of twists on the tooth flanks can be performed by suitable superimposition of corrections on the inner and outer tooth tips with corrections of the plunger position.

Method for producing continuous corrections in hypoid gears

In a process and apparatus for tooth-flank grinding of gearwheels, the opposing flanks of two adjacent teeth are initially ground simultaneously. In the terminal stages of the process, each flank is ground separately. A slight rocking motion of the gearwheel, provided by pivoted pawl in an indexing wheel, applies the grinding tool first to one tooth flank and then to the other. Any undesirable rounding off of the tooth flanks occurring during simultaneous tooth flank grinding can thus be corrected.

Apparatus for form-grinding the tooth-flanks of a cylindrical gearwheel

A dressing tool for a gear machine grinding wheel has a disc with a notch reproducing the tooth space of the gear ground by the machine. The flanks of the space open radially inward into a bore. A strip coated with diamond granules is removably affixed to the sides of the notch and looped around a clamp bolt in the bore which holds the strip taut. The tool, when dressing the wheel, is guided in the same manner as a gear when being ground.
