roller bearing

The invention relates to a rolling bearing, consisting of an outer race ring provided with lateral ribs, between the and an inner part with a cylindrical surface cylindrical rolling elements, in particular Roll bearing needles and in the case of a space between the rolling element set on the one hand and a board the outer race on the other hand one on the inner ring attached, radially outwardly extending locking ring engages.

Such bearings are expediently used where it is necessary to move the outer ring to the inner part set in the axial direction. This can be the case, for example, if the bearing outer ring itself or a can rotate freely with this connected part, e.g. as a guide roller on a shaft forming the inner part should without the outer ring being allowed to move in the axial direction on the shaft. Another conceivable Use case would be if such a rolling bearing made an outer race, an inner race and in between arranged rolling elements should exist and must be prevented before installation that the rolling elements from the Bearing fall out. This can be prevented by attaching a locking ring to the inner ring, which between the rolling element set and a board of the outer race engages, whereby a mutual axial displacement of the outer race to the inner ring

is avoided.

In known bearings of this type, the locking ring has been designed as a slotted spring ring, which is in a circumferential groove of the inner part was compressed.

The disadvantage of this design is that a separate additional operation on the inner part the circumferential groove has to be produced, which is the case with a mass-produced article such as a roller bearing of this type, leads to a relatively strong increase in price.

The object of the invention is to provide a rolling bearing ¹ S, which is the known embodiments fully equivalent from a technical look, but may be omitted in which the circumferential groove on the inner part.

This object is achieved by the invention in that the locking ring is L-shaped in cross section, and the axially extending collar of the L-profile is used for fastening on the inner part. With such a Execution, it is possible to either simply press the locking ring onto the inner part, or can also be attached by additional gluing, soldering or the like.

In the two figures of the drawing, exemplary embodiments of the invention are shown in longitudinal section.

The roller bearing shown in Fig. 1 consists of the outer race 1, the inner ring 2, and the between rolling bearing needles 3. The outer race 1 is directed radially inward at both of its axial ends Borders 4 and 5 provided. In the space 6 between the set of bearing needles 3 on the one hand and

PG 1680

the board 5 on the other hand protrudes the radially directed leg 7 of the locking ring 8, which with his axially directed collar 9 is pressed onto the inner ring 2. With an axial displacement of the inner ring 2, opposite the outer race 1, the radially directed leg 7 of the locking ring 8 reaches in sliding contact either on rim 9, or on the set of bearing needles 3. In this way, the inner ring set within narrow limits with respect to the outer race 1.

The bearing of FIG. 2 differs from that of FIG. 1 only in that the bearing needles 3 additionally are housed in a cage 10, and that instead of the inner ring 2, the inner part by a Shaft 11 is formed. The design and effect of the locking ring 8 are the same as in the execution according to Fig. 1, but here the radially directed leg 7 is not directly in one direction runs against the end faces of the bearing needles 3, but against the cage 10.

Claims (3)

PG 1680 - X'- Expectations Rolling bearing, consisting of one with side ribs provided outer race, between which and an inner part with a cylindrical surface cylindrical Rolling bodies, in particular bearing needles, roll off, and in the case of the in an interspace between the rolling body set on the one hand and a rim of the outer race on the other hand a fixed to the inner part, radially outward extending locking ring engages, characterized in that the locking ring (8) in cross section Is L-shaped, and the axially extending collar (9) of the L-profile for its attachment serves on the inner part (2, 11). 2. Rolling bearing according to claim 1, characterized in that that the locking ring (8) is pressed on. 3. Rolling bearing according to claim 1, characterized in that that the locking ring (8) is attached by gluing, soldering or the like.
