Abstract: A worm comprises enveloping worm teeth having relieved ends. The worm is machined in three steps comprising machining a threaded section, machining a first end section, and machining a second end section. The threaded section is machined utilizing a rack-form tool having a rack-form thickness. The first end section and the second end section are machined utilizing a larger rack-form thickness, thereby, providing relieved ends. The teeth of the worm having such relieved ends mesh with the teeth of a mating gear at full depth throughout preventing partial teeth engagement.

Abstract: A method of machining bevel gears whereby machining of both flanks of a tooth slot and crowning of the tooth surfaces in the lengthwise direction are realized without an active pivot axis and by a modification of the conventional relationship between the radial and swivel basic settings during gear generating.

Abstract: A method of chip-removal machining a tooth gap of a work piece includes executing a first substantially linear plunging movement of the cutting tool along a first plunge vector and machining a region of the work piece near a tooth head of a first tooth flank of the tooth. A substantially transverse movement of the tool along a transverse vector is then executed to machine a region of the work piece near a tooth head of the second tooth flank of the tooth. A second plunging movement of the cutting tool along a vector path is then executed, to an end point of the second plunging movement that lies at a position of the work piece corresponding to the slot depth of the tooth gap to be fabricated. The cutting tool is rotated about an axis of rotation thereof during execution of these steps.

Abstract: A method of producing internal gear teeth with deflecting surfaces such that the internal gear teeth are arranged in a component having an end and a longitudinal axis, as well as an end face that is offset relative to the end of the component in the direction of the longitudinal axis. The method comprises the steps of machining the end face of the internal teeth using a conical tool that rotates about a tool axis arranged parallel to the longitudinal axis, the rotating tool first being introduced axially and then moved along a circular path coaxial to the longitudinal axis, and finally being withdrawn parallel to the axis.

A method of designing a ring gear or pinion common outside chamfer tool and common inside chamfer tool for multiple gear ratios is also described.

Abstract: The invention relates to the production of plunge-cut crown wheels having straight or linear hypocycloid as the flank longitudinal line of the teeth. The production is performed by means of a forming method in which the axial movements are coupled. Corresponding pinions can be produced using a modified hobbing method. A corresponding tapered generating wheel is used. The milling tool carries multiple cutters. The teeth of the conical virtual generating wheel are reproduced in the engagement area by the blades or blade flanks of the cutters of the milling tool.

The shaving cutter includes a multiplicity of ribs forming the cutter tooth flanks, arranged in a manner substantially symmetrically with respect to each axial centerline of each of the cutter teeth, and each of the ribs has both a positive rake angle at its leading cutting edge and a negative rake angle at its trailing cutting edge as viewed in the direction of lateral sliding direction of along the tooth trace cutter.

Abstract: The present invention relates to a bevolute gearing system which transmits torque between non-intersecting shafts at right angles to each other. The bevolute gear system includes a pinion gear which is flat and in one plane. The pinion gear is designed to include teeth which are shaped in the form of an involute spiral. The bevolute gear system includes a second gear which is also designed to include teeth which are shaped in the form of an involute spiral. The second gear is mounted on a non-intersecting axis at a right angle to the axis of the pinion gear. The bevolute gearing system of the present invention reduces the thrust loads to negligible values for the bearings of both the pinion gear and the second gear. In addition,. higher mechanical efficiencies, wider tolerances on alignment of the gears, interchangeability between the gear and the pinions to produce different ratios and a substantially eliminated gear noise are a few of the many advantages disclosed in the present invention.
