Definitions
- the invention relates to a rolling bearing cage with circumferentially juxtaposed WälzMechurgin for receiving load-bearing rolling elements of a rolling bearing.
- rolling bearing cages which have for the guidance and spacing of rolling elements WälzSystemtaschen.
- WälzSystem sakefige be equipped with installation aids, so that a composition of the bearing is possible without much effort.
- the snap cage which is brought in the case of a radial roller bearing axially to the already arranged in the raceways rolling elements and snapped into this.
- the snap cage has a back region and a pocket region, wherein the pocket region is provided for receiving and guiding the rolling elements and the back region is provided for transmitting the axial force during the installation process.
- Such a snap cage is proposed for example in DE 10 2005 028 756 A1.
- Roller bearing cages also have designs for other tasks, which support the installation of the rolling bearing. Since often the cohesion of a variety of components (rings, cage and rolling elements) must already be ensured during installation, in the composition holding aids, the rolling bearing component of the temporarily hold together, quite beneficial.
- the object of the invention is therefore to provide an easily installable rolling bearing cage, which occupies as little space during the rolling bearing operation.
- the object is achieved by a roller bearing cage according to claim 1, or by a rolling bearing with such a cage.
- the roller bearing cage in the circumferential direction next to each other arranged rolling bearing pockets for receiving load-bearing rolling elements of a rolling bearing.
- the rolling-element pockets guide the rolling bodies, such as balls or tapered rollers, in the circumferential direction and provide P115093 Page 3 of 9
- the rear grip can take place both in the axial and in the radial direction.
- the decisive factor is that there is an installation advantage through this rear grip, which makes it possible to assemble rolling bearings more easily.
- the cage on the inner ring or on the outer ring provides support by the rear grip and the tapered rollers are inserted into the pockets of the rolling bearing cage while the latter bears against said bearing ring. After filling the pockets, the next installation step follows, such as the placement of another bearing ring.
- the end piece Oriented towards the rolling-body pockets, the end piece has a connection piece.
- This connector is structurally and / or materially weakened so that breakage of the connector can occur at a defined bending force.
- the connector acts as a predetermined breaking point, which is formed on the rolling bearing cage.
- the connecting piece is intended to break at a certain bending load in order to permanently separate the trailing end piece from the roller bearing cage. After separation, the tail can be disposed of and the resulting space continue to be used for rolling bearings, for example, for a seal assembly.
- the connecting piece is structurally weakened by means of a notch, a scoring or a recess.
- the structural weakening ensures the location of the fracture by virtue of a leverage effect resulting from the bending load, in that plastic deformation can first only occur at the structural weakening. This assumes that the tail is otherwise made stable in the way that at the required bending load in the rest of the tail no break is created. This is particularly advantageous if ensured P1 15093 page 4 of 9
- the structural weakening can take on very different forms, wherein a certain direction of actuation of the end piece can optionally be supported to the extent that it is preferred over another. This can be done by forming a notch or scribe either in the radial direction or in the circumferential direction. A notch in the radial direction would support an actuating direction of the end piece of the circumferential direction, which would make it easy to break off in said direction. The opposite applies to an orientation in the circumferential direction.
- the connecting piece is materially weakened by means of a doping or an admixture of a substance.
- the material of the rolling bearing cage is considered as a base material which can be enriched with a substance at the location of the connection piece, which need only be, for example, an impurity which weakens the material connection at this point. This is possible for example by the introduction of air bubbles or metal particles. Both would weaken the cohesion of the connector due to their base material of displacing volume.
- the material of the roller bearing cage, including the connecting piece can also be formed from a single material, wherein the connecting piece is formed by a yield point during the injection process.
- the yield point can thus serve as a predetermined breaking point.
- the engaging behind tail is formed as a retaining claw.
- the retaining claw is axially or radially on the rolling bearing component, such as an inner ring or a flanged wheel.
- the rolling bearing component could alternatively be a component of the sealing arrangement, which is the P1 15093 page 5 of 9
- the claw is, in order to achieve the desired combination under a certain bias, but may only lead to a low bending load of the connector, which must be well below the bending load required for a break.
- the engaging behind end piece can form or have an actuating element on the end remote from the rolling body pockets.
- the actuation of the actuating element is also facilitated if it continues at least partially in the circumferential direction.
- at least two permanently separable, engaging behind end pieces can be provided.
- end pieces are useful if it can be the attitude or positioning of the cage can be simplified.
- the bending load required for permanent separation is dimensioned such that breakage of the connecting piece can be carried out manually. This can be achieved by an appropriate choice of the basic material or by a certain structural or material weakening of the connecting piece or a combination of the two.
- the breaking of the connecting piece in the circumferential direction or radial direction can be assisted by the structurally and / or materially weakened connecting piece being weakened in the circumferential direction or radially.
- a notch in the connecting piece can be aligned in the circumferential direction or in the radial direction.
- a cage according to the invention can be used, for example in wheel bearings.
- 1 is a partially illustrated, single-row tapered roller bearing with a bearing cage with oriented in the circumferential direction predetermined breaking point
- Fig. 4 is a partially illustrated, single row tapered roller bearing with a bearing cage with radial predetermined breaking point.
- FIG. 1 shows a partially illustrated single row tapered roller bearing with a bearing cage with predetermined breaking point, which is formed from a materially weakened connecting piece 15.
- the flange 12 is applied to the inner ring 11 and forms together with the rolling elements and other parts not shown a single-row roller bearing, as used for example for wheel bearings in trucks.
- the extension 13 is the radially inwardly extending part of the retaining claw 14, which allows for the cohesion of the cage 16, the rolling elements 10, the inner ring 1 1 and the flanged wheel 12.
- the flanged wheel 12 can also be made in one piece with the inner ring 1 1.
- the assembly is thus very simple.
- the cage 16 is placed radially around the flanged wheel 12 and the inner ring 1 1, wherein it holds this axially without rolling elements 10 together. Thereafter, the rolling elements 10 can be used from the outside. Finally, only the outer ring (not shown) has to be placed in order to complete the single-row rolling bearing.
- the end piece 14 can now be actuated and separated by a fraction of the predetermined breaking point 15 from the rolling bearing cage, whereby sufficient radial space is recovered to secure the seal.
- FIG. 2 shows the roller bearing cage from FIG. 1 from the radial direction of view with the predetermined breaking point 15.
- the predetermined breaking point 15 is a notch 15, which is aligned in the radial direction with respect to the rotational axis of the roller bearing cage.
- Fig. 3 shows the rolling bearing cage of FIG. 1 with actuator 17 from the radial direction of view. Compared to FIG. 2, the end piece continues in the circumferential direction on both sides, thus supporting an actuation, in particular a manual actuation.
- FIG. 4 shows a partially depicted, single-row tapered roller bearing with a bearing cage with a radial predetermined breaking point.
- the tapered roller bearing and the roller bearing cage correspond to the tapered roller bearing of Figure 1, wherein the predetermined breaking point is not oriented only in the circumferential direction, but is oriented radially, so that the bending direction when breaking the tail 14 is directed rather radially.
- This can be selected from warehouse to warehouse so that in each case there is enough space for a handle or a machine abort.
- radial bearings is usually oriented in the circumferential direction of predetermined breaking point 15, as shown in Figure 1 be more advantageous because usually more space is available in the circumferential direction, as in the radial direction.
- the invention relates to a rolling bearing cage 6 with circumferentially juxtaposed WälzEffensen 18 for receiving load-bearing rolling elements 10 of a rolling bearing, wherein the roller bearing cage 16 at least one rolling bearing member 12 engaging behind tail 14 is formed.
- the end piece 14 which is ideally designed as a retaining claw, holds inner ring and rolling elements 10 together, but can be removed after or during assembly by predetermined breaking point 15 to make room for a further component, such as a seal assembly. Thus, despite the installation support an optimal space utilization is given.
