Embodiment Construction

[0038] Provision is made in the first step of an exemplary implementation of the method according to the invention to provide a circular disk.

[0039] Figure 1 to Figure 3 Three preparatory steps are shown in succession for an exemplary execution of the method according to the invention, wherein a circular disk is produced and provided for the method according to the invention.

[0040] figure 1 A sheet metal 1 made of hardenable steel material is shown, which is arranged in a stamping tool 2 . In a first preparatory step, a disc blank 3 , ie a punched blank with a circular contour, is punched out of the sheet metal 1 .

[0041] figure 2 Shown is a disc blank 3 in which a central circle section 5 is stamped in a second stamping tool 4, so that a circular disc 6 is produced in a second preparatory step, i.e. has a circular outer contour and a circular shape. Segments of the inner contour.

[0042] image 3The circular disk 6 is shown in the third stamping die 7 , where...

Abstract

The invention relates to a method for producing a bearing ring (20, 29), in particular a tapered roller bearing ring, comprising the following steps: making available an annular disc (8; 9), and forming the disc (8; 9) to give a substantially cylindrical bearing ring and producing a raceway (19; 28) of the bearing ring in a single operation by extrusion. According to the invention, the method achieves the object of providing a simple method for producing bearing rings, in particular for tapered roller bearings, which delivers high unit numbers and in which it is possible to dispense with a finishing operation.

Description

technical field [0001] The invention relates to a method for manufacturing bearing rings, in particular for tapered roller bearings, according to claim 1, starting from the provision of a disc made of homogeneous material, and to especially Bearing rings for tapered roller bearings. Background technique [0002] Manufacturing methods for bearing rings for rolling bearings are known from practice, which include in particular method steps of deep drawing or pressing. Such methods require reworking of the produced blank, for example by regrinding the raceways of the bearing ring on the blank, and are therefore cost-intensive to carry out. [0003] DE 10 2005 017 588 B3 describes a method for producing bearing rings for tapered roller bearings, in which a circular disc is provided and then axially deep-drawn. The blank requires further processing, for example a pressing step, in which the axially deep-drawn regions of the blank are processed further to give a shape. [0004] ...
