Abstract: A method for honing a workpiece includes moving the workpiece onto an intermediate retention member which is rotatable about a vertical workpiece axis. Then, the workpiece is brought into a rolling engagement with a teaching wheel. An angular transfer position of the workpiece is established by the rotary sensor of the teaching wheel retention member. Next, the workpiece is transferred from the intermediate retention member onto a workpiece spindle, where the workpiece is retained onto the workpiece spindle. Then, the workpiece goes through a honing process by bringing the workpiece into a synchronized rolling engagement with a honing tool by utilizing the angular transfer position of the workpiece, thereby eliminating a separate centering step of the workpiece.

Abstract: Race grooves and lobe outer surfaces of a constant-velocity race gear centered on a gear axis are finished by engaging a first groove of the race gear with a rotating groove-machining tool and relatively moving the race gear and rotating groove-machining tool arcuately to finish the first groove while holding the race gear against rotation about its gear axis. Then the first groove of the race gear is disengaged from the rotating groove-machining tool while holding the race gear against rotation about its gear axis. Then the race gear is rotated about its gear axis to align a second groove with the rotating groove-machining tool while engaging a first lobe outer surface with a rotating surface-machining tool to finish same. These steps are repeated in the same order to finish the second groove and a second lobe outer surface and so on until all the grooves and lobe outer surfaces of the race gear are finished.

The method proceeds on a machine tool (1) having two workpiece spindles (11, 12) which may exchange places. A workpiece (3) is mounted on a first workpiece spindle (11), followed by the workpiece spindles (11, 12) exchanging places, followed by pre-milling and, where applicable, cutting (=deburring by shaving) of the workpiece (3), followed by a further exchange of places, followed by chamfering and cutting of the workpiece (3), followed by a further exchange of places, followed by a finish-milling of the workpiece (3), followed by a further exchange of places, followed by a workpiece change. At the same time, the same procedure takes place on the second workpiece spindle (12), staggered in time by an exchange of places of the workpiece spindles (11, 12).

Abstract: A method for the manufacture of a toothed gear from a gear blank wherein the gear blank loaded into a machine tool and rotationally driven is machined by a hobbing cutter disposed on a rotationally driven tool shaft and the rough-hobbed gear, once produced, is subsequently cleared of burr by means of a rotationally driven deburring tool by causing it to chamfer the front-end edges of the inter-teeth grooves, wherein the number of revolutions of said deburring tool and rough-machined gear has a constant ratio, wherein the removal of burr is performed on said rough-machined gear invariably loaded on said machine tool in a continuous pass by using a deburring tool which is similar to a side milling cutter, has cutting teeth, and is fixedly disposed for rotation on the shaft of said hobbing cutter, wherein the front-end edges of the inter-teeth grooves are successively machined in the way of a gear hobbing process, and wherein said shaft is changed from the gear hobbing setting over to a burr removal setting.

Abstract: On account of the constructional form of the tool head (17) according to the invention, the opposite sides (18, 19) of a tool (13) attached to the tool spindle (14) of a numerically controlled continuously generating gear grinding or hobbing machine are capable of machining the upper and lower sets of teeth (2, 3) of a double-sided face-gear (1) in one and the same set-up and without disturbing the synchronization between the rotations of the grinding worm and workpiece maintained during the grinding of the first set of teeth, without risk of collision. This eliminates the need to reset the workpiece (1) between the machining of the two sets of teeth (2, 3), thereby shortening the overall machining time substantially, and allowing the avoidance of accuracy losses due to the resetting of the workpiece (1).

Abstract: This invention is directed to a method of using a two spindle Hurth-Module multi-spindle (or similar) cutting machine to accomplish face hobbing of hypoid and spiral bevel gear sets. A first cutter mounted on a first spindle would rough cut the gears and a second cutter mounted on a second spindle would finish the gears with both cutters using a face hobbing process. According to this process, multiple cutters are used for a single gear, but on a single machine, thereby reducing cutter wear, increasing cutter life, and raising production output of the multi-spindle machine by utilizing both spindles. In one embodiment, a fine pitch cutter is used to create the initial rough-cut of the gear, and a second coarse pitch cutter is used to create the finish cut of the gear.

Abstract: A base member such as an elevation pipe of a photographic tripod is severed and rack teeth are formed thereon in a single operation while the base member remains clamped in a V-block. The first rack tooth on each side of the location where the base member is severed includes half of a trough portion between adjacent rack teeth. Additional trough portions forming the remainder of the teeth are formed, either in the same severing and shaping operation, or in a later shaping operation. The formation of the inner half trough portions ensures that, when the two severed ends of the base member are brought together, a smooth transition will exist between the two rack portions. In addition, since the two severed ends always include half troughs immediately adjacent thereto, weaknesses and chipping resulting from the presence of partial rack teeth in these locations is avoided.

Abstract: An involute external tooth profile is cut into the periphery of a gear blank by positioning a rotating milling cutter with its cutting path perpendicular to the plane of action of the desired base surface of revolution within the gear blank so as to penetrate the plane of action from the side thereof opposite to the base surface and with a predetermined line of intersection which generates the involute profile as the base surface rolls upon the plane of action. The rolling action causes the generating line to traverse the blank between its addendum surface and a depth sufficient to provide the desired length of active profile.

Abstract: Apparatus for milling a gear for a double enveloping worm gear drive. A rotating milling cutter is advanced toward a workpiece spindle to mill a flank of a gear tooth by tilting the milling cutter supporting frame about an axis that passes through the axis of rotation of the workpiece spindle to form a predetermined change in the helix angle from the top to the root of the tooth. The initial tilt setting of the cutter is adjusted to suit the root helix angle.
