A multi-station, reciprocating die pattern forming machine (500), including a pair of parallel reciprocal slide members (502, 503) with spaced pairs of pattern forming dies (504) thereon reciprocal between an insert position and an eject position. Drive mechanism (505, 506, 510) reciprocates the die pairs alternately between the insert position and eject position. Mechanism delivers and positions a pattern receiving blank (600) to a pair of dies when in the insert position. Axial translation of the dies causes the dies to rotate the blank at a center of process and impart a pattern upon the blank. Servo-motors on blank positioning mechanism provide feedback recognition of the position of the blanks during processing. The invention also relates to a method of patterning blanks.

A method for roll-forming disk carriers or the like, which are designed as a pot-shaped sheet metal part having inner and outer teeth, wherein a multitude of cassettes is equidistantly arranged on the circumference of a roll-forming tool, said cassettes having profile rollers arranged in their interior, which roll out the disk carrier to be formed with their outer circumference and thus impart toothing on the disk carrier to be formed, wherein the forming depth of the profile rollers at the disk carrier to be formed is designed in such a way that a narrow, peripheral, self-contained, unformed bridge remains between the inner diameter and the outer diameter of the toothing, wherein the bridge increases the engine-speed strength of the disk carrier as a hoop band cylinder that is integrated into the toothing.

A rolling tool (5) has a basic body (6) for fastening the rolling tool (5) in a rolling machine (1) and a profiled part (7) for the shaping treatment of a workpiece (2) to be rolled. The basic body (6) and the profiled part (7) are of multi-piece design. The basic body (6) and the profiled part (7), in their interconnected position, are mounted movably relative to one another in a plane perpendicular to the rolling direction (23). The basic body (6) of the rolling tool (5) can also be part of the rolling machine (1).

A method for manufacturing a gear which effectively prevent a crack from occurring inside a tooth part when rolling processing is performed on a teeth part of a gear raw material is achieved. A method according to one embodiment for manufacturing a gear by performing rolling processing on a tooth part of a sintered gear raw material. The method includes, when the rolling processing is performed on the tooth part of the gear raw material, pressing the gear raw material toward a center of rotation of the gear raw material by a rolling machine and, when at least the rolling processing is performed on the tooth part of the gear raw material toward a center of a thickness thereof by a pressing machine, pressing a region where an internal density of the tooth part of the gear raw material decreases.

There is provided an R- table apparatus which freely movies one table on a plane in the forward-and-rearward and leftward-and-rightward directions and in the rotational direction. The R- table apparatus changes a horizontal distance between a center line of a main axis of a driving apparatus and the action point by elevating an elevating base, and a table is moved to an arbitrary position without rotating along a guide member.

The invention relates to a method for producing at least one gear, in particular a helically toothed gear, wherein the gear is produced from a gear blank pressed and sintered with an oversize in the region of the set of teeth, wherein the gear blank has two opposite end faces and a circumference. In the method, the gear blank is clamped in a clamping means. The gear blank is compressed in the region of the oversize by means of the engagement of at least one circumferential tool having a set of mating teeth that engages with the set of teeth of the gear blank, wherein the gear blank is radially clamped over the circumference by the clamping means at both end faces during the compression of the gear blank, wherein each individual tooth of the set of teeth of the gear blank is supported by the clamping means substantially over the entire tooth height. In this way, the quality of the set of teeth can be improved. The invention further relates to a device and to a clamping means.

A method may be used to produce a connecting element for transmitting rotational movements, wherein the connecting element has a joint outer part or flange and a connecting pin. The object of providing a method for producing a connecting element with a joint outer part or flange and a connecting pin, with which method weight-optimized connecting elements can be produced in a simple manner, is achieved in that a round-plate-like or tubular blank is deformed by flow forming or flow turning to form the connecting element.

A method for manufacturing a gear includes rotating a workpiece around a first axis, and rotating a plurality of cutting blades arranged annularly around a second axis skew to the first axis around the second axis. The method further includes, while causing the workpiece and the cutting blades to perform relative movement in a direction parallel to the first axis at a speed synchronized with a rotational speed of the workpiece, forming a helical tooth groove in an outer peripheral surface of the workpiece by the cutting blades. In a cross section perpendicular to the first axis, a diameter of a rolling circle in which an outline of the cutting blades and a target online of the gear make rolling contact with each other is larger than a diameter of a tooth depth center circle.
