10 a schematic representation of a cage

1 shows a tapered roller bearing according to the prior art. This has an inner ring 2 on, its outer surface 7 is inclined at a predetermined angle relative to the longitudinal direction L of the rolling bearing. An outer ring 3 of the rolling body has an inner surface 8th on, which is also inclined by a further angle relative to the longitudinal direction L. This angle to the outside surface 7 of the inner ring 2 is inclined relative to the longitudinal direction and the one to which the Innenoberflä che 8th of the outer ring 3 are inclined, are different. For this reason, the distance between the outer surface changes 7 and the inner surface 8th in the longitudinal direction L of the rolling bearing. Therefore, the rolling element must 5 be formed with a frusto-conical mantle surface. This in turn leads to the fact that it is necessary, the inner ring 2 with Borden 2a and 2 B to provide to the Wälzköper 5 respectively. This leads to a ramp-up of the rolling elements and thus to additional unwanted friction losses.

2 shows an inventive tapered roller bearing 1 , This bearing also has an inner ring 2 and an outer ring 3 on, between which the rolling elements 5 are arranged. The outer surface 7 of the inner ring 2 is inclined at a predetermined angle α with respect to the longitudinal direction L. The inner surface 8th of the outer ring 3 is also inclined at the same angle α with respect to the longitudinal direction L of the bearing. When considering these angles, any slight curvatures of the surfaces remain 7 . 8th In the determination of the angle α, a central region of the bearing is considered, in which the surfaces of the outer or inner ring at the in 2 embodiment shown are substantially planar.

By the same inclinations α of the inner surface 8th and the outer surface 7 is it possible that the rolling elements 5 be performed with a substantial constant diameter Dw. The reference number 4 refers to a cage through which the individual rolling elements 5 kept apart from each other. The reference numerals 12 refer to noses at the respective webs 6 the cages 4 are attached. As in 2 shown is the footbridge 6 of the cage 4 also by the angle α with respect to the longitudinal direction L of the rolling bearing 1 inclined.

At the cage 4 this is a metal cage. You realize that the bridge 6 of the cage 4 below the symmetry or rotation axis M of the rolling body 5 is arranged. Since the web is arranged below the axis of symmetry M, the rolling elements in this embodiment, inside, ie to the inner ring 2 held out.

The reference number 9 refers to a radially outwardly projecting projection on the cage 4 is arranged. Instead of one or a plurality of protrusions 9 could also be provided a radially outwardly directed collar. These radially outwardly facing projections 9 prevent falling apart of the tapered roller bearing in example during assembly. Exactly becomes by the projection 9 prevents the cage 4 with the rolling elements in 2 can be pulled out to the right. Without cradles or a collar the cage could 4 and the rolling elements are pulled off to the right and the rolling elements would be out of the between the webs 6 slip out of the gaps formed upwards. Pulling the cage to the left in 2 is also not possible because in such a movement, the rolling elements deeper into the pockets, ie the areas between the webs 6 would be pressed and in this way the movement would be prevented.

Instead of the embodiment shown here, other embodiments are conceivable, such as those in which the projection 9 is arranged on the right side, projects radially inwardly and is in positive connection with the inner ring. The cage shown here is preferably made of metal, but can be made of plastic.

The reference numerals 10a and 10b refer to annular rims of the cage, between which are the individual ridges 6 extend. These shelves 10a and 10b and the webs are integrally formed. The shelves are used to guide the rolling elements in their axial direction.

At the in 2 embodiment shown are in the direction of the rolling body 5 protruding projections 11a and 11b on the left and right side shelves 10a . 10b the cage provided. These projections 11a and 11b have a curved surface in the direction of the rolling body. In this way, the contact between the protrusions 11a and 11b or the Borden on the one hand and the rolling elements 5 or their end surfaces on the other hand can be improved. Also, in this way, the oil flow through the rolling bearing can be increased because lubricant more easily in the contact surfaces between the projections 11a . 11b and the end faces of the rolling elements 5 can occur.

The projections 11a and 11b can be executed pointwise, or in the form of a substantially circular on the shelves 10a . 10b arranged projection. By means of these projections of the rolling elements 5 guided in its axial direction, since the existing in the art ribs on the inner or outer ring are not present. With that the protrusions 11a and 11b over the prior art, a significantly improved embodiment.

3 shows a representation similar to that in FIG 2 however, various dimensions are shown for illustrative purposes.

The inner ring width IB is preferably greater than the length Lw of the rolling body 5 or this same. In this way, in essence, the complete surface or circumferential surface of the rolling body 5 in contact with the outside surface 7 of the inner ring. The ratio between the diameter Dw of the rolling element and the length of the Lw rolling element is in the 2 embodiment shown preferably between 0.1 and 1. For the overall height BH of the bearing, the following relationship applies: BH ≥ Dw · sin (α) + IB, where IB is also the inner ring width here. The product of the rolling element diameter Dw and the sine of the angle α determines the displacement x between the inner ring 2 and the outer ring 3 occurs.

4 shows a detailed representation of a rolling body. This rolling element 5 has a lateral surface 14 on. This lateral surface has the concave curved course described above. However, towards the end regions, the diameter Dw of the rolling element decreases, whereby a logarithmic relationship applies to this decrease. This course of the diameter prevents increased radial bearing wear from occurring as a result of radial loads occurring. Instead of a logarithmic acquisition from a linear decrease of the diameter would be possible. Also, other functional relationships would be possible for the decrease in diameter, such as those relationships that are composed of a linear and a logarithmic portion.

At the left and right ends of the rolling elements each have a bevel 15 on. At the in 3 In the embodiment shown, the chamfer runs 15 at an angle between 30 and 60 degrees and preferably between 40 and 50 degrees with respect to the longitudinal direction L.

5 shows a partial view of the end portion of a rolling body 5 , It can be seen that the diameter of the rolling element to the outside initially slightly and then in the end 15 relatively steeply decreasing (logarithmic course). Preferably, the rolling element 15 at the in 4 shown embodiment on a reinforced end profiling.

The end areas 15 have curved surfaces. This also strong wear of the bearing should be prevented by one-sided loads. The radius of curvature R of these curvatures is preferably less than 1 mm.

6 shows a further embodiment of the bearing according to the invention.

Unlike the in 2 embodiment shown is in the in 6 shown embodiment of the web 6 arranged above the axis of symmetry M of the rolling body. Also in this embodiment, it is preferably a metal cage.

At the in 6 Shown embodiment, the rolling elements 5 outside, ie to the outer ring 3 held out. The lead 9 , which is arranged in this case on the right edge, also prevents falling apart of the bearing. More precisely, the lead prevents 9 that the cage 4 in 6 can be pulled out of the camp to the left. Pulling out the cage 4 to the right, as noted above, by the arrangement of the web 6 prevented above the axis of symmetry M. The reference number 12 also refers in this embodiment to lugs on which the rolling body can start. By providing these noses 12 the oil flow, and thus the lubricity of the entire camp is significantly improved.

Also at the in 6 embodiment shown are projections 11a and 11b provided that the rolling elements 5 lead in the axial direction. These projections are on the two Borden 10a and 10b arranged.

7 shows a further embodiment of a rolling bearing according to the invention. In this case, the web has a first land area 6a on, which lies below the symmetry axis M of the rolling body, and two second land areas 6b , which are above this axis of symmetry M. Next to it is between the bridge areas 6a and 6b a sloping transition area 6c intended. This oblique profile increases the stability of the cage during operation.

At the in 7 In the embodiment shown, both the web areas extend 6a and 6b as well as the transition areas 6c in straight lines and join together. However, it would also be a curved or circular arc-shaped course of the web conceivable. The first two bridge areas 6a serve, similar to the in 6 shown embodiment, for holding the rolling body 5 , More specifically, if the cage is shifted to the right in the axial direction of the rolling element, the rolling element becomes closer to retaining lugs 12b pressed, thus preventing further displacement.

The first bridge area 6a , which is arranged below the axis of symmetry M, serves to guide the rolling elements. This is the bridge area 6a , And also the corresponding web portions on the other webs executed so that the distance between the guide lugs 12a , which are provided in these land areas, is slightly less than the diameter of the rolling element. This prevents falling out of the rolling element downwards, at least during assembly.

At the in 7 Shown embodiment, the web areas 6a and the bridge areas 6b in the radial direction of the bearing each equidistant from the axis of symmetry of the rolling elements. Therefore, in this embodiment, the distance that two with respect to a rolling body 5 opposite retaining lugs 12b and the distance, the two respect. A rolling element 5 opposite guide tabs 12a have, substantially the same.

In other embodiments, the first land areas 6a in the radial direction of the bearing further away from the axis of symmetry of the rolling elements, as the second web portion. In this case, the distance between two opposing retaining lugs is less than the distance between two opposing guide lugs.

The guide nose 12a at the footbridge area 6a is arranged, continues to take over the leadership of the rolling elements in the axial direction. You realize that the nose 12a a tarnishing surface 17 which has in 7 directed obliquely upwards, and to the rolling elements 5 can start. The tarnishing surface 17 runs substantially tangentially with respect. The lateral surface of the rolling elements by this arrangement of the contact surface which also increases the lubricity of the bearing, as a lubricant easier in the contact area between the rolling elements 5 and the contact surface 17 can occur and is not blurred by any edges of the contact surface. Corresponding geometries also apply to the contact surfaces of other holding or guide lugs.

The guide nose 12a points in the axial direction of the rolling body 5 a greater length than the two retaining lugs 12b , Due to this greater length, the leadership of the rolling elements 5 be simplified.

For this reason, at the in 7 embodiment shown the provision of a lateral projection or collar 9 not absolutely necessary, which is why the projections or collars 9 here only dashed lines are shown. In a preferred embodiment, however, are corresponding projections or collars nonetheless 9 provided and here in particular the right projection 9 , pulling out the cage 4 prevented to the left opposite the bearing.

In other words, due to the in 7 shown bearing geometry an axial start-up of the cage on one of the bearing rings 2 . 3 not absolutely necessary. However, as mentioned above, the axial starting of the cage can also be provided in this case to simplify the bearing mounting.

8th shows a further embodiment of a bearing, or cage according to the invention 4 , Again, this is a first dock area 6a provided between two second land areas 6b is arranged. Unlike the in 7 shown embodiment, however, here is the first land area 6a arranged above the symmetry axis M of the rolling body and the two web portions 6b below the symmetry axis M. Thus, at the in 8th shown bearings of the rolling elements held outside and guided inside. Again, in principle, on the lateral projections or collars 9 be waived. However, it is recommended, as above, also in this embodiment, at least the left-side projection 9 provide that prevents withdrawal of the cage to the right.

Instead of the embodiments shown here for the web, further embodiments are conceivable, such as webs, in which two land areas are arranged parallel to one another and each have two tabs in order to hold or guide the rolling body. In addition, for example, two first areas 6a and three second areas offset from each other 6b be provided, in which case the areas 6a and 6b each would be arranged alternately.

9 shows a further embodiment of a rolling bearing according to the invention, or a cage according to the invention 4 , In this embodiment, a plurality of webs 6 provided, however, compared to the webs in the embodiments shown above have an increased width in the radial direction. More precisely, the webs are at the in 9 embodiment shown arranged so that they are with a large part of their width above the axis of symmetry M of the rolling elements 5 are arranged, and only with a small portion below this symmetry axis M. Thus, in the in 9 shown cage, which is preferably a plastic cage, also held the outside of the rolling element and guided inside.

At the rolling element 5 facing surfaces have the webs 6 at the in 9 shown embodiment curved surfaces which are adapted to the also curved surfaces of the rolling elements. These surfaces prevent the rolling element from emerging upwards out of the cage. In the 9 embodiment shown is particularly suitable for plastic cages. The reference numerals 10a and 10b refer to left- or right-hand rims of the cage, for the axial guidance of the rolling elements 5 serve. Between these shelves are the individual bars 6 arranged.

Conversely, it would also be possible to make the webs so that they slightly above the Symmetry axis M of the rolling element 5 run and with a larger share below. In this case, the rolling elements would primarily inside, ie from the inner ring 2 be kept here. Also, a symmetrical variant would be conceivable in which the individual webs are arranged substantially symmetrically with respect to the axis of symmetry M of the rolling elements.

In addition, also at the in 9 shown embodiment (not shown) protrusions 11a . 11b to be provided in the manner shown in the preceding figures.

10 shows a schematic representation of a cage according to the invention 4 , It can be seen that next to the noses 12 attached to the lateral surface of the rolling elements 5 abutment, also projections 11a and 11b are provided, which the respective end faces of the rolling body 5 can touch. The in 10 shown cage pockets 19 the largest possible oil flow rate for the bearing, and minimizes the friction at the contact surfaces between the cage by their shape 4 and the rolling element 5 , The individual projections may also each have curved surfaces in the direction of the rolling body.

As mentioned above, there is in principle tapered roller bearings, the possibility to perform the bearing rings bordlos. This results in the possibility to change the assembly sequence of the bearing components, and to adapt to the particular installation. So it is possible for tapered roller bearings compared to tapered roller bearings that also the outer ring with the rolling elements and the cage is assembled into one component. In the in the 7 and 8th embodiments shown, it is also possible to carry out the existing of the rolling element and cage assembly as a single component, since the rolling elements by the retaining lugs 12b and the guide nose 12a prevented from falling out of the cage.
