Abstract
A method can be employed to produce a rack for a steering gear. The rack may include a toothed portion with a toothing, and a shaft portion with a functional portion. Separate segments comprising at least one in each case bar-shaped toothed segment and one shaft segment may be provided, which are aligned on a common longitudinal axis and are connected to one another at a joint. The method may involve providing a shaft raw material piece having a length that is a multiple of a shaft segment length, continuously grinding a part of a circumferential face of the shaft raw material piece across a multiple of the shaft segment length to produce a semi-finished shaft segment product, cutting to length a shaft segment from the semi-finished shaft segment product, providing a toothed segment, and joining the shaft segment to the toothed segment.
