Abstract
A housing for receiving a bearing component is presented, which has a shaft projection, which can be inserted into the recess of the end area of a hollow section and can be pressed together with the end area, wherein the shaft projection is provided with a groove profile, in which the groove profile is prepared by a deformation process or an original shaping process. Notch effect and consequently a weakening of the cross section on the highly stressed shaft projection is avoided by the said processes. The present invention pertains, moreover, to such a groove profile located at a shaft projection of a housing.
Claims20
A housing for receiving a bearing component comprising:
- a shaft projection including a groove profile prepared according to a one of a forging operation and an original shaping process which includes a casting operation;
- a hollow section including an end area with a recess, said shaft projection being inserted into said recess and pressed together with said end area.
A housing for receiving a bearing component, the housing comprising:
- a shaft projection having a substantially round cross section with a center and including a groove profile prepared according to a deformation process or an original shaping process, said groove profile further comprising a plurality of depressions arranged next to each other in an axial longitudinal direction of said shaft projection and distributed in a circle segment-like pattern over circumference of said shaft projection, said circle segment-like pattern having a center of curvature offset from said center of said substantially round cross section;
- a hollow section including an end area with a recess, said shaft projection being inserted into said recess and being pressed together with said end area.
A housing for receiving a bearing component, the housing comprising:
- a shaft projection having a substantially round cross section with a center of curvature, a circumferential direction and an axial longitudinal direction, said shaft projection defining a plurality of depressions on an outside of said shaft projection, each said depression being shaped as a segment of a circle extending in said circumferential direction of said shaft projection, a center of curvature of said segments of a circle being spaced from said center of curvature of said substantially round cross section, said depressions being arranged next to each other in said axial longitudinal direction of said shaft projection;
- a hollow section including an end area with a recess, said shaft projection being arranged in said recess and being pressed together with said end area.
