The present invention relates to a holding plate rolling bearing combination, comprising a holding plate / bearing glasses / retaining glasses / bearing plate having at least one projection which holds in a retaining groove of at least one rolling bearing outer ring, wherein at least in the radial direction between the retaining plate and the rolling bearing outer ring and resetting damping ring is inserted.

From the DE 10 2011 075 493 B4 is a bearing assembly with a bearing carrier, having a bearing outer ring bearing and disclosed with a closed holding element which engages in a groove of the bearing outer ring so that the bearing outer ring is fixed in its axial and preferably radial position on the bearing support, wherein the holding element is a circumferential change The spring element is connected to two sections of an axially extending flange portion in the circumferential direction.

From the DE 103 55 407 B3 is a bearing assembly consisting of a bearing and a bearing support known, wherein the bearing support is designed to be fixed to a machine part and wherein the bearing is permanently connected to the bearing carrier. In order to improve the economy in the manufacture and assembly of the bearing assembly, it is provided that the bearing and / or the bearing carrier have at least one radially directed incision, which is at least partially seen in the axial direction is an undercut, wherein the connection between the bearing and bearing carrier means a plastic molded part is produced, which is produced in the bonding process of bearing and bearing carrier by in-situ injection molding by molten plastic material is injected into the recess and between the bearing and bearing support with a predetermined axial and radial alignment of the two parts to each other.

Furthermore, from the DE 103 55 363 B4 a bearing arrangement consisting of a bearing and a bearing carrier, wherein the bearing support is designed to be fixed to a machine part and wherein the bearing is connected to the bearing carrier, wherein the bearing support at least two plastic molded parts are arranged permanently, each having a predetermined Extending portion and wherein the bearing has on a cylindrical surface with radially outward or inward surface normal at least one groove-shaped recess which at least partially seen in the axial direction of the bearing is an undercut, wherein the at least two plastic moldings by in-situ injection molding are connected to the bearing bracket, wherein the at least two plastic molded parts engage in the at least one groove-shaped recess so that the bearing and the bearing support are axially and radially fixed relative to each other and wherein the groove-shaped recess is a groove which is standardmäßi gene recording a bearing seal is provided.

Further prior art is further from the EP 2 014 937 B1 , of the DE 10 2004 031 830 B4 , as well as the DE 10 2005 012 323 B3 known.

Rolling bearings can be fixed by means of a "snap connection" in a bearing plate consisting of sheet metal. For this purpose, a groove is mounted in the outer circumferential surface of the bearing outer ring by machining. At the periphery of the bearing seat of the holding plates a plurality of snap lugs are embossed radially inwardly running, which "snap" when joining bearing and holding plate in the groove of the bearing outer ring. The connection method, however, entails play between the bearing outer ring and the retaining plate, which results from the component tolerances required for the snap connection.

This axial and / or radial clearance between the bearing and the bearing seat in the retaining plate is clearly felt and leads to a "rattle" in the handling of the assembly, which is undesirable. To eliminate this axial and radial play, several possibilities are already known from the prior art, which, however, all require additional, sometimes very complex, manufacturing steps, which can not be easily integrated into the existing manufacturing process.

In addition, there may be problems with the assembly of the bearing plate on the transmission shafts due to the game.

A possible method for producing the snap connection provides that a hole is formed in the bearing plate, which serves as a bearing seat for the rolling bearing. Subsequently, snap lugs are embossed running radially inwards on the circumference of the bearing seat. On the peripheral surface of the bearing outer ring, a groove is mounted, in which snap the snaps in the assembly of bearing and bearing plate. Due to the component tolerances that are necessary for the snap connection exists between bearing and bearing seat (in the retaining plate) above-described axial and radial clearance.

The object of the invention is to avoid or at least mitigate the disadvantages of the prior art and in particular the rattling without having to extensively adapt the previous production process.

The object of the invention is achieved by a generic holding plate roller bearing combination in that the damping ring is designed as a one-piece / circumferential O-ring.

Advantageous embodiments are claimed in the subclaims and are explained below.

Thus, it has proven to be advantageous if the O-ring is placed / received in a separate from the retaining, preferably axially offset from this arranged, Dämpfungsringaufnahmenut. The provision of a separate Dämpfungsringaufnahmenut offers the advantage that the previously used bearings must be extended only to this groove and no additional new parts and / or steps are necessary.

It has also proved to be advantageous if the entire damping ring made of an elastic material, such as rubber, rubber or a similar elastomer, completely / completely constructed. Due to the elastic material, it is possible to compensate for the necessary component tolerances, so that no more radial and / or axial clearance is available.

It is also advantageous if the damping ring receiving groove is formed deeper than the retaining groove. By the different depth of the grooves a clear assignment is ensured, and it can not happen accidentally that the engaging into the retaining projections inadvertently engage in the Dämpfungsringaufnahmenut.

An advantageous embodiment provides that the projections / the projection are designed as snap lugs / is. These snap-action lugs protrude radially inwards on the circumference of the bearing seat, and snap into the retaining groove provided during assembly of the rolling bearing and the bearing plate.

In other words, the invention consists in that an existing due to the snap connection between the bearing and bearing seat in the retaining plate axial and radial clearance must be compensated or turned off, the principle of the snap connection should be maintained. The previous series process only has to be completed by the step "Fit O-ring to outer ring". This requires no complex and complex production facilities.

It can therefore be said that in order to reduce or eliminate the clearance between the bearing and the bearing seat, an O-ring is to be inserted into a groove of the bearing outer ring before the bearing and the retaining plate are brought together. The O-ring is pressed and compressed during assembly of bearing and bearing plate in the designated groove. As a result, the detectable clearance between the bearing plate and outer ring is significantly reduced or prevented the "flaps".

In other words, the invention provides a damping ring which is provided / installed in the bearing seat of the holding plate between the holding plate and the bearing outer ring.

The invention will be explained in more detail with the aid of figures. Show it:

1 a longitudinal sectional view of a holding plate-rolling bearing combination according to the invention;

2 a detailed view II 1 in an enlarged view;

3 an overall perspective view of the retaining plate rolling bearing combination;

The damping ring receptacles 10 is in the axial direction of the bearing 6 seen closer to a rolling element 11 arranged and designed deeper than the retaining groove 4 ,

Into this damping ring receptacle groove 10 becomes the O-ring 8th during assembly of the warehouse 6 and the holding plate or bearing plate 2 pressed in and compressed. This means that the depth of the damping ring receptacles is good 10 at least slightly less than a diameter of the damping ring 7 so that it is actually compressed during installation and thus can compensate for the axial and / or radial play.

So that the damping ring 7 can be compressed, it is, preferably completely, formed of an elastic material. This may be for example a rubber, a rubber or another elastomer.
