Device for non-rotatable connection a bearing ring or the like on a shaft

The innovation relates to a device for the non-rotatable connection of a bearing ring or the like on a shaft, wherein sections of the part to be fastened are clamped to the shaft by appropriate means.

Devices of this type are z. Known from US-PS 1,561,443. In this known construction the widened inner ring of a roller bearing is provided with an eccentric shoulder on one side Outer surface a ring with an eccentric recess is placed »By turning the eccentric ring, the end section of the inner ring is compressed in the radial direction and the bearing clamped to the shaft. The eccentric ring is fixed on the shaft by a screw.

In this known device, precise shaft dimensions must be adhered to. It also has this connection only a low clamping strength and is only insufficiently secured against loosening due to vibrations.

The object of the present innovation is to provide a device for the rotationally fixed connection of a bearing ring or Like. To create on a shaft that can be manufactured inexpensively and has a great clamping strength as well has a high axial load capacity.

According to the present innovation, this object is achieved in a device of the type mentioned at the beginning solved that the bearing ring or the like. On one or both sides at a distance from the end face at least has a transverse incision to the axial direction, the depth of which is greater than the wall thickness of the Bearing ring and the one in the axial direction deformable portion of the bearing ring limited, and that in the Incision means for spreading the deformable portion, e.g. B. a conical threaded pin engages.

This configuration achieves a high level of clamping strength and ensures that the conical threaded pin is secured against loosening by the elastic spreading.

In the subclaims, further refinements of the concept of innovation are described, in addition to one Incision of the .Lägerringes still an incision can be provided, both of which are further deformable Limit section. This creates a large clamping surface that ensures a firm connection, without the part of the inner ring carrying the inner raceway is canted.

In an embodiment of the innovation, the deformable section of the bearing ring has an axially running threaded bore in which a threaded pin resting on the side surface of the incision facing away from the end face of the bearing ring is arranged, which enables the deformable section to be easily spread apart.

According to other features of the innovation z. B. the bearing ring in the area of the incision with a recess converging side walls, between which a slotted ring engages with corresponding side surfaces. Of the The slotted ring, which is tensioned radially, causes particularly high clamping forces and reliably prevents the bearing or the like from loosening on the shaft.

Some exemplary embodiments of the innovation are shown in the accompanying drawing.

Show it:

FIG. 1 shows a longitudinal section through a bearing mount according to the invention, in which the inner ring with an incision running transversely to the axial direction is provided and the bracing of the

Bearing on the light is done by a conical grub screw, which is a deformable Section of the inner ring spreads,

Figure 2 shows a longitudinal section of a modified embodiment with two transverse to the axial direction running incisions in the inner ring,

Figure 3 is a longitudinal section through an embodiment in which the deformable portion by a screw acting in the axial direction is spread apart,

Figure 4 shows a further embodiment in which the fixing of the bearing ring on the shaft by a slotted conical ring takes place.

The embodiment according to Figure 1 consists of a deep groove ball bearing 1 with an inner ring 2 which is widened on one side and which is at a distance from the end face with an incision running transversely to the axial direction, preferably extending beyond the bearing axis 3 is provided with a small width, which is a deformable in the axial direction portion 4 of the inner ring 2 limited. In the area of the incision 3, the inner ring 2, starting from the lateral surface 5, is provided with a provided radially extending conical threaded bore 6, in which a conical threaded pin 7 engages. After this • Pushing the bearing 1 onto a shaft 8 will result in the

jjj 20 threaded pin 7 screwed into the threaded hole 6. Hierii when the deformable section 4 of the inner

ring 2 and a firm clamping connection is created between the inner ring 2 and the shaft 8.

The embodiment shown in Figure 2 differs from the construction just described in that In addition to the incision 3, a further incision 9 is provided, which delimits a second deformable section 10. When screwing in the conical threaded pin 7, the deformable sections 4 and 10 are in opposite directions Directions spread apart and with the shaft 8

In the case of the bearing shown in FIG. 3, the deformable section 12 of the inner ring 13 is axial with one extending threaded bore 14 is provided, into which a threaded pin 15 is inserted. The tip 16 of the threaded pin 15 is supported when screwing in on the side surface 17 of the facing away from the end face of the bearing ring Incision 18 and spreads the deformable section 12 of the inner ring 13.

Figure 4 shows a bearing in which the inner ring with an incision 19 and a recess 20 with conical side walls 21 is provided, between which a ring 22 slotted at one point on the circumference with converging Side surfaces 23 engages. The lateral surface 24 of the ring 22 is also designed conical and lies on a corresponding inner surface 25 of a nut 26, which on a threaded section 27 of the inner ring 28 is arranged. When the nut 26 is screwed onto the threaded section 27, the slotted conical ring 22 reduced in diameter and pressed into the recess 20. Here, the section 29 of the spreads Inner ring 28 and clamps the bearing 1 with the shaft 8. The incision 19 is made so deep that the The bending point for the section 29 is below the incision 19 and so is the entire section 29 with the nut 26 is splayed.

The innovation is not limited to the exemplary embodiments described above. It is straightforward possible to spread the deformable portion 4 of the bearing ring 2 by other means or more than two incisions 3, 9 to be provided. The deformable sections 4 can also be provided on both sides of the inner ring will.
