Abstract

A combined radial-axial rolling bearing for rotatably mounting a rotary body in the region of a diameter step. The rolling bearing has a radial bearing unit which is assigned to a circumferential surface of the rotary body and which at least has a radial bearing ring, and an axial bearing unit which is assigned to an axial surface of the rotary body and which at least has an axial bearing ring. To mount the rotary body radially in the region of larger diameter, the radial bearing unit is assigned to a circumferential surface which has the larger diameter. The radially outer rim of the axial bearing ring is latched to a rim of the radial bearing ring which faces toward the radially outer rim, such that the two bearing rings form a structural unit which can be assembled in one work step, but otherwise remain functionally separate.

Claims

1. A combined radial-axial rolling bearing for rotatably mounting a rotary body in a region of a diameter step, comprising:

a radial bearing unit which is assigned to a circumferential surface of the rotary body and which at least has a radial bearing ring; and

an axial bearing unit which is assigned to an axial surface of the rotary body and which at least has an axial bearing ring,

wherein the radial bearing unit is assigned to the circumferential surface which has a larger diameter, with a radially outer rim of the axial bearing ring being latched to a rim of the radial hearing ring which faces toward the radially outer rim.

2. The combined radial-axial rolling bearing of claim 1, wherein the radial bearing unit comprises a radial bearing ring which is designed as an inner ring, and a radial bearing cage which is arranged on an outer side of the radial bearing ring and holds rolling bodies.

3. The combined radial-axial rolling bearing of claim 1, wherein the axial bearing unit comprises an axial bearing ring which bears against the axial surface, and an axial bearing cage which is arranged on a side of the axial bearing ring which faces away from the axial surface, the bearing cage holding rolling bodies.

4. The combined radial-axial rolling bearing of claim 1, wherein latching means are arranged on at least one of the rims, which face toward one another, of the radial bearing ring or of the axial bearing ring, into which latching means the respective other of the rims is latched.

5. The combined radial-axial rolling bearing of claim 4, wherein the latching means are formed as latching lugs which are arranged distributed about the rim of the radial bearing ring.

6. The combined radial-axial rolling bearing of claim 2, wherein the rolling bodies are rollers or needles.

7. The combined radial-axial rolling bearing of claim 1, wherein the radial bearing ring and/or the axial bearing ring are/is formed as a sheet-metal ring shaped in a non-cutting process.

8. The combined radial-axial rolling bearing of claim 3, wherein the rolling bodies are rollers or needles.
