Method for chipless manufacturing a bearing ring for a rolling bearing and rolling bearing with the bearing ring

摘要

Rolling bearings have in many designs an inner ring, an outer ring and a plurality rolling elements rollingly arranged between inner ring and outer ring. The inner ring and the outer ring are very often machined from solid material. Such solid rings have the advantage of high rigidity and a low manufacturing tolerance. However, the production of massive rings is expensive due to the required semi-finished product and due to the manufacturing process. Against this background, it has already been proposed to produce rings of a rolling bearing without cutting. It is an object of the present invention to propose a method for manufacturing a bearing ring for a rolling bearing, which is particularly cost-effectively implemented. For this purpose, a method for manufacturing a bearing ring 2; 3 proposed for a rolling bearing 1, wherein the bearing ring 2; 3, a raceway side 22; 32 with at least one raceway 23; 33 and an attachment side 21; 31 for abutment with a support structure and wherein the bearing ring 2; 3 defines a major axis H of the rolling bearing 1, the bearing ring 2; 3 by forming from a bearing ring blank 26; 36 is manufactured, and wherein the bearing ring blank 26; 36, a surface profile 28; 38, wherein the surface profile 28; 38 after forming at least one contour section 24; 34 in the plant side 21; 31 of the bearing ring 2; 3 forms.
