Description

Roller Bearing
Technical Field
The invention relates to a roller bearing, comprising at least one inner bearing ring and at least one outer bearing ring, wherein roller elements are arranged between the bearing rings.
Background
To secure a sufficient lifetime of the bearing the same must be lubricated. Of-ten, grease is employed for lubrication which must be kept in the contact area between the bearing rings and the roller elements. Especially in the case of a taper roller bearing the grease tends to leave the contact area between the bearing rings and the roller elements due to centrifugal forces. So, it is diffi- cult to make sure that sufficient grease remains in the contact area of the bear-ing.
It is an o bj e c t of the present invention to further develop a roller bearing of the generic kind which allows a more efficient lubrication of the bearing.
This is aimed especially for those bearing types in which centriftigal forces during operation try to remove the lubricant from the contact between the bearing rings and the roller elements, like e. g. taper roller bearings.
Summary of the invention
A s o 1 u t i o n according to the invention is characterized in that at least one of the bearing rings comprises a cavity for receiving a lubricant, which cavity is facing one of the face sides of the roller elements.
Preferably, a separate ring element is firmly connected with at least one of the bearing rings, wherein the ring element comprises the cavity.
In the preferred case of using a separate ring which contains the cavity it can be provided that the firm connection between the ring element and the bearing ring is a press fit connection. Also, it is possible that the firm connection be-tween the ring element and the bearing ring is a glued connection.
The ring element can be arranged in a groove of the bearing ring. The groove can thereby have a rectangular shape in a radial cross sectional view.
The cavity has preferably a concave shape in a radial cross sectional view.
Here, a preferred embodiment proposes that the cavity has a half-elliptical shape in a radial cross sectional view; also a half-circular shape can be pro-vided.
The ring element is preferably made from metal, especially from steel, or from plastic material.
According to a preferred embodiment only one single cavity is arranged; this cavity is preferably arranged at the inner bearing ring.
A further embodiment of the invention is characterized in that the roller bear-ing further comprises a cage, wherein the cage has a first guidance surfitce io which is designed for contacting the ring element at a corresponding second guidance surface. Thereby, the first and second guidance surfaces can have a perpendicular which is directed into the radial direction.
The cage can furtheniiore form a second cavity at an axial end remote from the ring element, wherein the cage has a third guidance surface which is de- signed for contacting the bearing ring at a corresponding fourth guidance sur-face.
The roller bearing is preferably a taper roller bearing.
Thus, the roller bearing according to the invention -preferalby being a taper roller bearing -has preferably an additional ring which is a replacement of the small rib of the bearing (location with the smaller diameter of a taper roller bearing). This ring is designed in a such way that it can play the role of a small reservoir for the lubricant.
At operating speed of the roller bearing the internal groove (cavity) of the ring is providing lubricant to the region of the raceways of the bearing. In the standstill mode of the bearing (while some leakage can be expected) the cavity can again collect at least some of the lubricant.
In operation and assuming that the cavity is arranged at the rotating bearing ring (preferably the inner ring) the rotating ring will generate a "pumping" effect to the lubricant toward the large rib (location with the bigger diameter of a taper roller bearing). This effect is used to improve the lubrication of the roller bearing.
io The additional ring can also be used to guide the cage at the small rib outside diameter. In general, this is improving the behavior of the bearing and is also limiting the leakage of the lubricant (grease).
In the same manner the cage can be modified on the large rib outside diameter so that it can serve as a container I reservoir (second cavity) for the used grease and also redirect the grease toward the contact area between the bearing rings and the roller elements.
So, the roller bearing according to the invention has a lubrication tank for storing a lubricant, especially grease.
Brief description of the drawings
The drawing shows embodiments of the invention.
Fig. 1 shows a radial cross sectional view through a taper roller bearing according to a first embodiment of the invention and Fig. 2 shows a radial cross sectional view through the taper roller bearing according to a second embodiment of the invention.
Detailed description of the invention
In Fig. 1 a first embodiment of a roller hearing according to the invention is io depicted.
The roller bearing 1 is a taper roller bearing and has an inner bearing ring 2 and an outer bearing ring 3. Roller elements 4 are ananged between the bear-ing rings 2, 3. The roller elements 4, i. e. the taper rollers, are guided by a cage 9.
To improve the lubrication of the roller bearing I a ring element 7 is arranged at one axial end of the inner bearing ring 2. For doing so, a groove 8 is ma-chincd into thc inner bearing ring 2. The ring element 7 is fixed to the inner bearing ring 2 by a press fit between the inner cylindrical area of the ring el-ement 7 and the respective outer cylindrical area of the groove 8.
The ring element 7 has a cavity 5 for receiving lubrication grease. As can be seen from Fig. 1 the cavity 5 has approximately a semi-elliptical shape in a radial cross section. Thus, the cavity 5 is open to one side, namely to the face side 6 of the roller elements 4.
That is, when the inner bearing 2 is rotating during operation the grease in the cavity 5 is forced in a flow dfrection F as depicted in Fig. 1 due to centrifugal forces. I. e. a certain pumping effect is generated.
For secure guiding of the cage 9 the following provision is made: The cage 9 has at its left axial end side adjacent to the ring element 7 a section which is extending radially inward; here a first guidance surface 10 is created which is plane and which has a perpendicular which is directed into the radial io direction r.
At the radial outer side of the ring element 7 a second guidance surface 11 is established which is also plane and has also a perpendicular which is dfrected into the radial direction r. Thus, a small gap exists between the two guidance surfaces 10 and 11. The cage 9 can contact the ring element 7 at the second guidance surface 11 with the first guidance surface 10 of the cage so that the cage 9 is securely guided during operation.
A further development of this principle is shown in the embodiment accord-ing to Fig. 2.
This embodiment is very similar to that one according to Fig. 1. The only dif-ference is the design of the cage 9.
As can be seen here, the cage 9 is elongated in the right axial end region of the same. The material of the cage 9 is formed to establish a second cavity 12.
Grease can be received in this second cavity 12.
To further improve the guidance of the cage 9 a third guidance surface 13 is established at a radial inner end section of the cage. Again, the perpendicular of this flat guidance surface 13 is directed into the radial direction r.
Finally, a fourth guidance surface 14 is established at the inner bearing ring 3 at the large outer surface of the inner bearing ring 2. Thus, due to a possible contact between the two guidance surfaces 13 and 14 a proper guidance of the cage 9 at its right axial end is guaranteed.
io That it, the lubrication of the taper roller bearing is improved. Also the guid-ance of the cage is optimized.
With regard to the embodiment according to Fig. 2 it should be noted that beneficially the rigidity of the cage 9 is significantly increased (compared with the design according to Fig. I).
On the other side the assembly of the bearing is here more ambitious as in the case of the design according to Fig. 1.
In the case of the embodiment according to Fig. 2 assembly takes place by placing at first the rollers 4 in the cage 9; then, the cage is pinched (reduction of the diameter of the cage at its right axial end) in order to get its final size and form respectively as depicted in Fig. 2. By doing so it is made sure that the rollers remain securely in the cage.
Additionally, as in the case of the embodiment according to Fig. 1, the form of the left axial end of the cage also provides a certain rigidity of the cage.
A preferred assembly sequence in both depicted cases is consequently the fol-lowing: At first the cage 9 with the rollers 4 and the inner bearing ring 2 are mounted.
Then, the ring element 7 is mounted onto the inner bearing ring 2 (using pref-erably a tight fit).
Beneficially, this process of assembly is easy and provides that that all of the components remain assembled as in the case of a standard taper roller bear-ing.
