Definitions
- the invention relates to a bearing for receiving axial loads, consisting of a plurality of roller bearings arranged one behind the other, each with a housing washer, a shaft washer and roller body sets arranged between these running disks, the shaft washers and the housing washers being axially supported by spacer rings arranged between them.
- a known design for a bearing for receiving axial loads is referred to as a "tandem bearing".
- Several, mostly two to four axial bearings are connected to one unit, in which the disks on the shaft (shaft disks) and the disks in the housing (housing disks)
- a uniform load on all sets of rolling elements is achieved in that the running disks and the cages are all designed differently from one another in the sense of a uniform deflection.
- edge support which is well known in rolling bearing technology and in which the rolling elements only transmit loads over a part of its length, therefore also plays an important role in the case of a plurality of rolling bearings arranged one behind the other. If this was not solved, this would lead to an overload on both the rolling elements and the associated points on the raceways, which could lead to premature failure of the entire rolling bearing arrangement.
- the attempts described above to solve this problem in the case of a plurality of roller bearings arranged one behind the other in the axial direction are too complex. Summary of the invention
- the invention is therefore based on the object, on the one hand, to significantly simplify the design and manufacture of a bearing for receiving axial loads, and, on the other hand, to increase the service life and the functional reliability of the bearing by uniformly distributing the load on the individual axial rolling bearings.
- this object is achieved according to the characterizing part of claim 1 in conjunction with its preamble in that the housing washers and the shaft washers in the area of the rolling element sets have the same axial thickness over their entire radial extent and at least one of the shaft washers on its inner circumference with an annular shape , is provided in the radial direction inward open exemption.
- the lower wave washer should be provided with an annular exemption, while according to claim 3, the upper wave washer should have this exemption.
- the arrangement of the exemption in the lower shaft washer is the normal case if the force acting on the bearing arrangement is allowed to run from top to bottom, ie in the direction of gravity. This is the case, for example, with deep drilling rigs if the force towards the center of the earth comes from a motor that has to move a drill towards the center of the earth.
- the force exerted on the bearing acts in the horizontal direction.
- the lower wave washer is the wave washer that is furthest away from the point of application of the force.
- a safety ring is arranged in at least one of the exemptions.
- This safety ring prevents excessive deformation or even breaking of the wave washer, which would otherwise be caused by excessive force acting on it.
- the system is thus much stiffer, since the safety ring can absorb an additional part of the acting force without damaging the shaft washer.
- the safety ring must be designed individually for each application. This applies, for example, to the material used, which is said to be elastic according to claim 5. But the size and cross-sectional shape of the safety ring also have an influence on the stiffness of the shaft washer.
- the safety ring should have a slot. This is primarily necessary to make assembly easier.
- FIG. 1 shows a longitudinal section through an axial bearing arrangement according to the prior art
- FIG. 2 shows a longitudinal section through an axial bearing arrangement with an exemption according to the invention
- FIG. 3 shows the course of the lines of force through a wave washer provided according to the invention with an exemption
- FIG. 4 shows the load distribution over a rolling element, the shaft washer of which is provided with or without the release according to the invention
- FIG. 5 shows a longitudinal section through a bearing arrangement according to the invention with an exemption and a safety ring
- Figure 6 is an enlarged view of the section marked in Figure 5 and
- FIG. 7 is a plan view of a slotted security ring. Detailed description of the drawings
- the bearing shown in Figure 1 for absorbing axial loads consists of four axial roller bearings arranged one behind the other. These each consist of a housing washer 1.1, 1.2, 1.3, a shaft washer 2.1, 2.2 and roller sets 3.1, 3.2, 3.3, 3.4 arranged between these washers. These consist of cylindrical cages 3.1.1, 3.2.1, 3.3.1, 3.4.1 see rolling elements 3.1.2, 3.2.2, 3.3.2, 3.4.2 together.
- the housing washers 1.1, 1.2, 1.3 are each axially supported by spacer rings 4.1, 4.2 and the shaft washers 2.1, 2.2 by the spacer ring 5.1.
- the force F is broken down into two partial forces F1, F2, a force flow F1 taking place via the upper shaft washer 2.2, the rolling element set 3.3, the housing washer 1.2, the spacer ring 4.1 up to the housing washer 1.1.
- the second associated power flow F2 also starts from the upper shaft washer 2.2, continues via the spacer ring 5.1, reaches the lower shaft washer 2.1 before the housing washer 1.1 is reached again via the roller body set 3.1.
- the lower wave washer 2.1 provided with an annular, in the radial direction open inward exemption 6.
- the partial force F2 which is transmitted from the spacer ring 5.1 to the lower shaft washer 2.1, is deflected by the relief 6 in such a way that the rolling elements 3.1.2 of the rolling element set 3.1 are subjected to the force F2 evenly over their entire length ,
- the force curve shown in FIG. 4 according to curve b over the axial extent of the rolling elements 3.1.2 results.
- Curve b in Figure 4 shows that an almost equal surface pressure of about
- FIGS. 5, 6 and 7 show a bearing arrangement according to the invention for absorbing axial loads, in which a safety ring 7 provided with a slot 7.1 is inserted in the clearance 6. It can be seen that through this safety ring 7 the rigidity of the wave washer
