A rack for a steering gear of a motor vehicle may include a toothed portion having a toothing, and a shaft portion. Separate segments comprising at least one in each case bar-shaped toothed segment and one shaft segment are provided, are aligned on a common longitudinal axis, and are connected to one another at a joint. The method may involve providing a raw material piece having a piece length that is a multiple of a segment length, thermally continuously hardening the raw material piece across a multiple of a segment length to produce a hardened semi-finished segment product, cutting to length a hardened segment from the hardened semi-finished segment product, providing a further segment, and joining the hardened segment to a further segment.

A method for deburring bevel gears using a deburring tool, which comprises at least one cutting edge, having the following steps: rotationally driving the deburring tool around a deburring spindle axis, rotationally driving a bevel gear around a workpiece spindle axis, wherein the rotational driving of the deburring tool and the rotational driving of the bevel gear take place in a coupled manner with an inverse coupling transmission ratio, it is a continuous method for deburring, in which the cutting edge executes a relative flight movement in relation to the bevel gear, the relative flight movement is defined by a hypocycloid, and wherein a burr is removed at least on one tooth edge of a tooth gap in the region of the bevel gear toe and/or the bevel gear heel by a cutting contact of the cutting edge with the tooth edge.

A method for producing honing tools (24) that are conjugate to the bevel pinions and ring gears (26) they are intended to hone and which can be produced (e.g. cut) on a standard bevel gear free form machine. The method is described by two transformation steps with the basis of the transformations being the theoretical generating gear. The invention relates also to a toothed bevel honing tool produced by such a method and a method of honing bevel gears when provided with such a tool produced by such a method.

A gear assembly that can prevent a reduction in power transmission efficiency and a manufacturing method thereof are provided. The gear assembly comprises a first gear and a second gear. The gear assembly is designed in such a manner that first gear tooth and the second gear tooth are contacted properly to each other in a plane of action when operated in a predetermined condition. A rigidity reducing portion is formed on a first base portion to avoid improper contact in the plane of action when the gear assembly is operated in a different condition.

The present disclosure relates to a method for the gear manufacturing machining of a workpiece by a diagonal-generating method, in which the workpiece is subjected to gear tooth machining by the rolling off of a tool, wherein an axial feed of the tool takes place during the machining with a diagonal ratio given by the ratio between the axial feed of the tool and the axial feed of the workpiece. According to the present disclosure, the diagonal ratio is changed within the course of the machining of a workpiece.
