Abstract

The invention concerns a rolling bearing ( 1; 1 ′) with a one-piece outer bearing ring ( 3 ) and a one-piece inner bearing ring ( 2 ), and with rolling elements ( 4 ) arranged in at least one row between the bearing rings ( 2, 3 ). Provision is made in this rolling bearing that the outer bearing ring ( 3 ) and/or the inner bearing ring ( 2 ) has, on the axial end face, at least one cutout ( 10 ) through which the rolling elements ( 4 ) can be placed into the space between the bearing rings ( 2, 3 ), that the cutout ( 10 ) can be covered with a reversibly attachable cap ( 9 ), and that the cap ( 9 ) forms a rim ( 11 ) for guiding the rolling elements ( 4 ). The lateral cutout ( 10 ) for filling the rolling bearing ( 1 ) with rolling bodies permits cage solutions of segmented or strip design that are larger than a rolling element and hence can accommodate multiple rolling elements. The suitability of the rolling bearing for high rotational speeds and the stiffness of the rolling bearing are increased as a result.

First claim

The invention claimed is:

1. A rolling bearing comprising:
a one-piece outer bearing ring;
a one-piece inner bearing ring; and
rolling elements arranged in at least one row between the inner and outer bearing rings, wherein at least one of the outer bearing ring and the inner bearing ring has, on an axial end face, at least one cutout through which the rolling elements can be placed into a space extending from the inner bearing ring to the outer bearing ring, the at least one cutout being covered with a removably attachable cap, such that the cap forms a rim for guiding the rolling elements, the rim having an inclined surface that is inclined at a first angle relative to the longitudinal axis of the rolling bearing and covers the space, wherein the inclined surface is perpendicular with respect to an axis of rotation of the rolling elements, and wherein the rolling elements roll on races that are inclined at a second angle relative to the longitudinal axis of the rolling bearing.

2. The rolling bearing according to claim 1 , wherein the rolling elements are arranged in two rows that are positioned in an “O” arrangement with respect to one another, and the outer bearing ring has two of the cutouts.

3. The rolling bearing according to claim 2 , wherein the cutouts are arranged to be mutually offset with respect to the circumference of the rolling bearing.

4. The rolling bearing according to claim 1 , wherein the cap and the at least one cutout are large enough that at least one of spacers separating the rolling elements, cage segments, and a cage strip can be introduced into the at least one cutout.

5. The rolling bearing according to claim 1 , further comprising a fastening element, wherein the cap is removably attached to the rolling bearing using the fastening element.

6. The rolling bearing according to claim 1 , wherein the rolling elements are (i) arranged in cage segments, (ii) arranged in a cage strip, or (iii) spaced apart from one another by spacers.

7. The rolling bearing according to claim 6 , wherein the rolling elements are arranged in cage segments, and the cage segments each accommodate at least one rolling element in at least one pocket.

8. The rolling bearing according to claim 6 , wherein the rolling elements comprise a running surface, and wherein the rolling elements are arranged in cage segments, and the cage segments are designed such that the entire running surface of the rolling element can be utilized for rolling.

9. The rolling bearing according to claim 6 , wherein the rolling elements are arranged in cage segments, and the cage segments are designed with a radial bend.

10. The rolling bearing according to claim 6 , wherein the rolling elements are arranged in cage segments, and the cage segments have a sealing or stop strip.

11. The rolling bearing according to claim 6 , wherein the rolling elements are arranged in cage segments, and the cage segments are made of plastic, brass, or aluminum.

12. The rolling bearing according to claim 6 , wherein the rolling elements are arranged in cage segments, and adjacent cage segments are connected to each other.

13. The rolling bearing according to claim 6 , wherein the rolling elements are arranged in a cage strip, the cage strip having a sealing or stop strip.

14. The rolling bearing according to claim 1 , wherein the rim on at least one of the outer ring, the inner ring, and the cap have at least one lubricant pocket.
