Definitions
- the invention relates to a provided for use in a pin cage having a rolling bearing, hollow rolling elements and a method for producing such a rolling element.
- a rolling element of the type mentioned in the introduction is known, for example, from DE 10 2007 031 792 A1.
- the rolling element is designed as a cylindrical roller and represents a component of a roller bearing with a pin cage.
- the rolling element can be made of case hardened steel and case hardened.
- a known method for hardening rolling bearing components is disclosed, for example, in DE 100 20 1 18 B4.
- the rolling bearing is designed in this case as a needle bearing.
- DE 10 2009 031 064 A1 relates to a bearing arrangement which also has needle rollers as rolling elements. Parts of the bearing assembly are inductively hardened in this case.
- the invention is based on the object of providing a rolling element which is suitable for a roller bearing, in particular a cylindrical roller bearing and having a bolt cage, which has good wear properties and which can be produced efficiently, and to a corresponding production method. Summary of the invention
- the rolling element has a cylindrical, frustoconical or barrel-shaped basic shape and a central bore.
- the bore can be designed as a through-hole or blind hole.
- the bore is provided to engage in a pin of a rolling bearing cage.
- the inner surface is inductively hardened. Further surfaces of the rolling element are its end faces and its lateral surface.
- the following further surface or the following further surfaces can optionally be inductively hardened: a single end face,
- a tool suitable for this purpose which has at least one coil, can be introduced into the bore of the rolling element.
- the hardness of the inner surface achievable with this method is at least 650 HV 0.3, in particular at least 700 HV 0.3.
- the advantage of the invention is in particular that a cost-effective tempering steel can be used for a roller bearing with a pin cage, which is suitable for inductive hardening.
- An embodiment of the invention will be explained in more detail with reference to a drawing. Herein show:
- FIG. 2 is a rolling body of the rolling bearing of FIG. 1 in plan view
- FIG. 3 is a sectional view of the rolling element according to FIG. 1.
- a rolling bearing namely cylindrical roller bearing, designated as a whole by the reference numeral 1
- a cage 6, namely a pin cage is provided, which has two cage disks 4 and a number of these connecting bolts 1 1, wherein each bolt 1 1 penetrates a bore 10 of a rolling body 5.
- the rolling elements 5 schematically illustrated in FIGS. 2 and 3 each have a lateral surface 9 rolling on the bearing rings 2, 2, two end surfaces 7, and an inner surface 8 delimiting the bore 10.
- Each of the surfaces 7, 8, 9 of the roller body 5 is inductively hardened.
- the roller bearing 1 may, for example, also be designed as a tapered roller bearing, a roller bearing or a spherical roller bearing. LIST OF REFERENCE NUMBERS
