摘要： 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.

摘要： A reciprocating die roll forming machine for forming a pattern such as a thread form on the outer surface of a cylindrical blank includes at least one set of reciprocating dies operating upon the blank which rotates in place. The machine includes a slide and bearing combination to support the dies belt driven by a servo-motor controlled by a central processing unit. Mechanism is provided to deliver and position a blank for engagement by the dies. In one form, the machine includes multiple die sets to produce multiple parts during one die reciprocation cycle. In another form, the machine employs separate drive mechanisms to independently drive each die of a set.

摘要： 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.

摘要： In the production of an internal contour with an internal arbor acting on the inner wall of a cup-shaped or annular rotationally symmetrical workpiece, expansion and length change of the workpiece are avoided during cold forming. Thus, gear components with internal teeth are produced that have greater symmetry and higher accuracy. A workpiece provided with a press fit on the outside or a prefabricated workpiece is inserted into the die, and during the cold forming is pressed tightly by friction and rotationally fixed with the rotationally driven internal arbor against the inner wall of the die. After completion of the rolling process of the profile, the workpiece is ejected with an axial ram. The internal arbor is provided with outside profiling and is cantilever-mounted and is fed axially and radially during the rolling.

摘要： An apparatus for smoothing gear wheels has a single smoothing wheel and two further smoothing wheels opposite the single smoothing wheel. A clamping device for axially clamping the gearwheel to be smoothed can oscillate in a direction perpendicular to its rotation. The smoothing wheels are mounted on bearing brackets, which may be tensioned against one another in such a way that the gearwheel to be smoothed positioned between them is centered and may have a predetermined force applied to it. The bearing brackets form a separate clamping unit that is movable in parallel in such a way that the axis of rotation of the gearwheel to be smoothed runs coaxially to the central axis of its clamping device, which may oscillate.
