Abstract
A bearing unit having a roller bearing that includes an outer ring and an inner ring that is rotatable with respect to the same about an axis, The inner ring is fastened to a first component, and the outer ring is fastened to an adapter ring that is nonrotatably and axially movably supported on a second component. A method for manufacturing a structural unit and an electric motor are also provided.
Claims7
A bearing unit comprising:
- a first component;
- a second component;
- an adapter ring that is non-rotatably and axially movable movably supported on the second component, the adapter ring being axially movable along an axis;
- and
- a roller bearing comprising an outer ring and an inner ring that is rotatable with respect to the outer ring about the axis, the inner ring being fastened to the first component, and the outer ring being fastened to the adapter ring,
- wherein the adapter ring has a circumferential body wall, a length of the circumferential body wall, in an axial direction that is parallel to the axis, being smaller than a length of an outer circumferential surface of the outer ring in the axial direction, such that when the outer ring is fastened to the adapter ring, the circumferential body wall of the adapter ring partially overlaps the outer circumferential surface of the outer ring in the axial direction so that the adapter ring partially surrounds the outer ring,
- wherein the adapter ring has at least two extensions that protrude from an outer surface of the circumferential body wall and run substantially in parallel to the axis, each of the at least two extensions being guided in a corresponding receptacle of the second component and each of the at least two extensions being monolithic with the circumferential body wall.
