Method for producing a flanged disk for a spherical roller bearing and spherical roller bearing having a flanged disk produced according to the method

1. A method for producing a flanged disk for a spherical roller bearing, the method comprising the following steps:

bending an initially straight tube portion into a ring having two ring ends separated by a gap;

thermally joining the two ring ends together to form a closed ring; and

subsequently shaping the closed ring into a flanged disk having an axial cross-sectional geometry that deviates from a circular shape.

2. The method as claimed in claim 1 , wherein the shaping step includes shaping the flanged disk to have a substantially trapezoidal axial cross-sectional geometry such that a surface area formed radially on an inside of the flange disk is axially shorter than a surface area formed radially on an outside of the flanged disk.

3. The method as claimed in claim 1 , further including introducing at least one venting bore into the straight tube portion or the ring.

4. The method as claimed in claim 1 , wherein the straight tube portion has a wall thickness of between 1 mm and 3.0 mm.

5. The method as claimed in claim 1 , bending the straight tube portion to have an outside diameter of between 15 mm and 30 mm.

6. The method as claimed in claim 1 , wherein the joining step includes joining the two ring ends together by electric resistance welding.

7. The method as claimed in claim 1 , wherein the shaping step includes shaping the thermally joined ring into the flanged disk in a press by a contouring tool.

8. The method as claimed in claim 7 , wherein the shaping step includes shaping the thermally joined ring in the press by a contouring tool in a single pass.
