この公知の方法の木質的な欠点は、軌道輪の容積増大が
大きいため軌道輪から母材への移転部に高い残留応力が
生じ、これが転がり軸受外輪の形状の精密さ及び転がり
疲労強度を損なうことがあることである。(Prior Art) In known methods of this type, the materials of the raceway of the outer ring of a rolling bearing and its base material are selected in such a way that during hardening the raceway increases in volume to a greater extent than the base material surrounding the raceway. (West German Patent No. 2745527) (Problems to be Solved by the Invention) The wood-related disadvantage of this known method is that the volume of the bearing ring is increased so much that the transition from the bearing ring to the base material is difficult. High residual stresses occur, which can impair the geometric precision and rolling fatigue strength of the outer ring of the rolling bearing.

る。Furthermore, although only the outer ring can be manufactured using the known method, the inner ring and attached rolling elements of a rolling bearing cannot be manufactured.
This is because, in a rolling bearing member having a raceway provided on the outer surface of the base material, the raceway increases in size even more severely and separates from the base material during quenching. However, the inner ring or rolling element of a rolling bearing with a hardened bearing ring is made from rolling bearing steel! 1lIJ! ! [Efforts are being made to

ている。(Means for Solving the Problems) In contrast, the present invention as set forth in claim 1 improves the method for manufacturing rolling bearings so that it can be applied to manufacturing rolling bearing members of arbitrary shapes. It is intended to.
それに加えて、この転がり軸受要素の製造方法では、軌
道輪７か母材への転移部に生ずる残留応力を低くする事
である。In addition, this method of manufacturing a rolling bearing element is intended to reduce the residual stress occurring at the transition between the bearing ring 7 and the base material.

Ｃｒ６から成り、母材はより安価な鋼、から成ることが
可能である。By means of the method according to the invention, only the raceway of the rolling bearing is made of expensive through-hardened rolling bearings, such as steel 21, for example steel grade 10, O of the West German Industrial Standard D I N 13505.
The base metal can be made of cheaper steel.

の重さをその母材と比較して大幅に軽くすることができ
る。When a rolling bearing member is hardened, the volume of each bearing ring and its base material increases by approximately the same amount due to common austenitization. In this way, only a small amount of residual stress is generated at the transition point from the raceway to the base metal due to the transformation of the structure during quenching. Therefore, the weight of the raceway can be reduced with the force that allows the raceway to be made thinner. It can be significantly lighter than its base material.
転がり軸受部材の焼入れの際の軌道輪と母材との等しい
容積増大によって、軌道輪が転がり軸受、部材の焼入れ
の際に母材から離脱する恐れなく。Due to the equal volume increase of the bearing ring and the base material during hardening of the rolling bearing member, there is no fear that the bearing ring will separate from the base metal during hardening of the rolling bearing and the member.

The deformation is performed while the bearing ring 5 and/or the base material 6 are in a cold or hot state. After compression and/or deformation, each bearing ring 5 of the rolling bearing component, which is firmly joined in one piece with the base material 6, has a wall thickness of 2 to 10 mm.

The base material 6 has a martensitic structure and the base material 6 has a martensitic structure. In this case, the hardness of the base material 6 is approximately 40 on the Rockwell hardness C scale.

解法で被覆することが最適である。In order to create a particularly strong bond between raceway ring 5 and base metal 6, it is often advisable to coat each raceway 5 and/or its base metal 6 with a thin metal layer before compression or deformation. . This is because during the heat treatment of the rolling bearing member, the metal of the above layer diffuses into the rolling bearing steel of the bearing ring(s) 5 and into the steel of the base material 6 at the transition zone. The metal layer, which can consist of copper, is optimally applied electrolytically to a thickness of 1 to 2 micrometers.

Since only a small amount of stress is generated, it is possible to increase the rolling fatigue strength in addition to the precision of the shape.
