Description

Field of the invention

The invention relates to a storage, in particular a bearing insert.

Background of the invention

It is known to subdivide bearings in two storage units or put together from two storage units.

The publication DE 10 2005 034 717 A1 describes a sealed rolling bearing with a two-part inner ring, a two-part outer ring and two arranged therebetween Wälzkörperreihen, wherein in the region of a joint between the two outer part rings a seal is provided.

The publication DE 10 2010 017 964 B4 describes a rolling bearing with a two-part outer ring, wherein the two part outer rings each have in one of their mutually facing axial end portions a groove-shaped recess in which a connecting and sealing ring is arranged by means of press fit.

Summary of the invention

The object of the present invention is to provide a possibility with which the mounting of a bearing from a first bearing unit with an inner ring, an outer ring and rolling elements arranged therebetween and a second bearing unit with an inner ring, an outer ring and arranged therebetween rolling elements, in particular composable simplified can be.

This object is achieved by a bearing which has a connecting ring for connecting the first bearing unit to the second bearing unit, which comprises a latching device for connecting the first bearing unit to the second bearing unit and a seal for sealing between the first bearing unit and the second bearing unit. In this case, the first bearing unit can be connected or connectable in particular by the connecting ring with the second bearing unit.

By virtue of the fact that the connecting ring comprises both a latching device, for example a clip, and a seal, for example a central seal, the assembly can advantageously already be simplified in that only one (single) component is used, for example instead of a clip for connecting the first and second bearing unit, which is for example mounted in the bore of the inner rings, and additionally a central seal, for example between the inner rings of the bearing units, - is used for two functions, such as the assembly of the bearing units and the avoidance of oil and / or grease contamination. In addition, by the use of such a connecting ring advantageously the production of the bearing units, for example, the inner rings and / or outer rings are simplified because - for example, on the inside of the inner rings or in the bore - on an additional clip recording or (central) seal receiving, which otherwise could be formed, for example, by an additional turning and / or grinding process step, can be dispensed with. In particular, the assembly can be further simplified by the connecting ring, that the connection of the first bearing unit with the second bearing unit is performed by the locking device. In addition, so advantageously damage to the connecting ring during assembly and possibly over the life of the bearing can be avoided, thereby reducing assembly costs and / or the life of the bearing can be improved.

In one embodiment, the locking device of the connecting ring for connecting the inner ring of the first bearing unit with the inner ring of the second bearing unit is designed. Thus, advantageously, the assembly can be further simplified.

In a further embodiment, the latching device of the connecting ring on the outer circumference of the inner ring of the first bearing unit and on the outer circumference of the inner ring of the second bearing unit can be latched. In other words, the connecting ring can be mounted, for example, in each case on the, opposite the bore side of the inner ring of the first and second bearing unit.

In another embodiment, the seal can be pressed by the latching device against the inner ring of the first bearing unit and against the inner ring of the second bearing unit. In this way, the locking device can press the seal against the respective inner ring and thus ensure their function.

For example, the seal, for example in the form of a central seal, can be arranged or accommodated in the latching device, for example in the form of a clip. In particular, the seal, for example in the form of a central seal, can be integrated into the latching device, for example in the form of a clip. Or vice versa, the locking device, for example in the form of a clip, can be integrated into the seal, for example in the form of a central seal. For example, the latching device and the seal, in particular fixed, be interconnected. So it is advantageously only necessary to handle a single component.

The latching device of the connecting ring can, for example, have a first latching element, for example a first latching lug, and / or a second latching element, for example a second latching latch. The first and second latching element of the latching device may for example be circumferentially segmented or circumferentially segmented or interrupted. If appropriate, the latching device of the connecting ring can furthermore have a first latching depression, for example the first latching groove, and / or a second latching recess, for example the second latching groove. The first and second latching recess of the latching device may, for example, circumferentially, for example in the form of a groove-shaped recess formed. In addition, the latching device can have at least one seal receiver, optionally a first seal receiver and a second seal receiver. The seal receptacle of the latching device may, for example, circumferentially, for example in the form of a groove-shaped recess formed.

The inner ring of the first and the second bearing unit, for example, a detent recess, for example in the form of a detent groove have. In particular, the first detent element of the latching device of the connecting ring can engage / engage in the latching recess of the inner ring of the first bearing unit and the second latching element of the latching device of the connecting ring can engage / engage or can be latched in / engageable with the latching recess of the inner ring of the second bearing unit. The detent recess of the inner ring of the first and the second bearing unit may, for example, circumferentially, for example in the form of a groove-shaped recess formed. Optionally, the inner ring of the first and the second bearing unit further comprise a latching element, for example in the form of a latching nose. The locking element of the inner ring of the first and the second bearing unit may be formed, for example circumferentially circumferentially. In addition, the inner ring of the first and the second bearing unit may have a seal receiver. The seal receptacle of the inner ring of the first and the second bearing unit may, for example, circumferentially, for example in the form of a groove-shaped recess formed.

It is also possible that the connecting ring has two or more seals, for example in the form of O-rings, and is designed, for example, as a double-sealing system.

The latching device may be formed, for example, of a metallic material. Depending on the field of application, however, the connecting ring, in particular the latching device and the seal (s), can also be made of different materials, for example plastic and / or steel and / or aluminum.

The rolling elements may for example be rollers, for example tapered rollers. The bearing may in particular be a bearing insert, for example of two or more bearing units, for example for a hub unit, for example wheel hub. The storage units can also be referred to as storage units.

For example, the bearing can be used at a wheel end of a vehicle, for example as a wheel bearing. For example, the bearing can be used on a front axle and / or on a rear axle of a vehicle, for example commercial vehicle and / or truck, and / or on a trailer axle. For example, the bearing can be used in a front axle module and / or rear axle module and / or trailer axle module. For example, the bearing may be a bearing insert for a powered or non-driven rear axle or front axle or trailer axle.
