Definitions
- the invention relates to a multi-row rolling bearing comprising a divided outer ring consisting of at least two coaxial rings, the at least two rings of which abut one another by contact surfaces lying on their axial end faces.
- the invention further relates to a method for manufacturing and a method for mounting such a rolling bearing.
- Such a rolling bearing may e.g. be used as a storage concept for supporting the rotor shaft in a wind turbine.
- the bearing of the rotor shaft in wind turbines is often designed as a so-called Einlager concept.
- Einlager concept In contrast to conventional two-point or three-point supports with two or three separate bearing points, when loading
- a single bearing provides both axial and radial forces as well as moments.
- This single bearing consists for example of two attached tapered roller bearings or a double-row axial tapered roller bearing in conjunction with a radial cylindrical roller bearing.
- tempering steel which is often used in large rolling bearings, has the disadvantage that the fatigue life of the hardening layer is substantially lower than the rolling bearing or case hardening steel.
- a bearing steel is in turn hardly suitable due to the low toughness.
- the requirements can be met by hardened steel with surface hardening.
- the use of case-hardening steel continues to pose risks through the heat treatment process, as it can cause high stresses in the material and render the workpiece unusable. Critical is especially the phase after carburizing. It is true that the larger the Inn Vietnamese bemesser the cross-sectional profile of the rings to be cured, the greater the risk of cracking.
- the size of the cross-sectional profile is predetermined by design specifications, eg number of raceways on a ring or required, minimum area moment of inertia.
- the cross-sectional profile of outer rings in Einlager- concepts due to the at least two tracks has a necessarily complex shape.
- the complex and sometimes massive cross-sectional shape of the outer rings based on the fact that the outer ring is not necessarily completely supported over its axial extent on its outer circumferential surface. This requires a flow of force within the outer race from each raceway to the area of the outer surface supported by a connecting structure.
- US 4,798,482 discloses a double row radial bearing assembly having an axially split outer and an axially split inner ring. According to one embodiment of US Pat. No. 4,798,482, the two halves of the outer ring abut each other directly with their axial end faces and are held together by a fastening means. The flow of force through the rolling bearing takes place separately via both ring halves. It is therefore necessary to support both rings over their entire axial extent.
- the invention has for its object to provide a multi-row roller bearing, on the one hand a simple and cost-effective production and assembly allowed and on the other hand in a Einlager concept in which the outer ring does not have to be fully supported over its axial extent can be used. Summary of the invention
- this object is achieved in a multi-row rolling bearing according to the preamble of claim 1 such that the contact surface of a ring at least one cavity and the contact surface facing this contact surface of an adjacent ring has at least one engaging in the cavity connecting element.
- this object is further achieved by a method for producing an outer ring of a multi-row rolling bearing according to the invention, the method comprising the following steps:
- this object is further achieved by an assembly method for a multi-row rolling bearing according to the invention, the assembly method comprising the following steps:
- the advantage is thus that by the division of the outer ring hardening of each of the at least two rings can be done separately.
- the Inn Vietnamese be- diameter of the rings to be hardened can be reduced by appropriate division of the outer ring so that the risk of cracking is greatly reduced.
- the intervention of a connecting element of a contact surface is provided in an opposite cavity of the adjacent contact surface. This makes it possible that a force transmission in the radial direction of a ring half in the adjacent ring half is possible.
- the outer ring according to the invention therefore does not have to be supported over its entire axial extent, since the radial force component of a ring, which is not supported by the connecting structure in the radial direction, can be transmitted to a ring, which is supported in the radial direction by the connecting construction.
- the at least one cavity located between two abutting rings and the connecting element engaging in this cavity enable centering of these rings and force transmission in the radial direction between these rings.
- the at least two coaxial rings are centered with respect to their coaxiality. This requirement may e.g. be met by correspondingly accurate fits between connecting element and cavity.
- the force to be transmitted in the radial direction between the at least two rings depends on the particular application and the at least one connecting element must be designed accordingly in order to ensure this power transmission. In particular, the shape and the number of connecting elements can be determined accordingly.
- the at least one connecting element of the contact surface of the adjacent ring is formed integrally with this ring.
- a connecting element for example a circumferential web, can be formed by a return of the axial end face of the ring, for example by twisting.
- the position of the connecting element can be set very precisely in this case, whereby a good Coaxial centering is possible.
- the connecting element forms a projection, a nose, a survey, a pin, a web or a clip.
- the at least one connecting element of the contact surface of the adjacent ring is formed by a separate fixing element, which is positively connected to the adjacent ring.
- the fixing element in a cavity in particular a groove, a bore, a recess or a trough, the adjacent ring is fitted.
- the preparation of a corresponding cavity is not a major requirement for the production. Compared to a connecting element, which is formed integrally with the ring, the production is cheaper and faster to accomplish.
- a cavity forming by two opposite cavities for the fixing element is mirror-symmetrical with respect to the plane formed by the two abutting contact surfaces.
- the insertion of the fixing is simplified so that care must be taken no special orientation with respect to the respective rings.
- the at least one connecting element and a cavity are connected via an interference fit.
- the connecting element can thus also transmit - at least small - axial tensile forces, so that the composite outer ring forms a unit during assembly.
- a radial force transmission is directly possible by press fits, without that the respective ring halves would have to move radially until it stops against the connecting element.
- interference fits are preferably present between the fixing element and both cavities.
- the at least one cavity of the contact surface forms a groove, a bore, a recess or a depression.
- the groove extends concentrically to a rotational axis of the rolling bearing. So it creates a circumferential groove. This can be manufactured easily and inexpensively. Due to the great length of this groove, a high power transmission in the radial direction is possible.
- the at least one cavity of the contact surface has a semicircular, rectangular or V-shaped cross-sectional profile.
- the respective cross-sectional profile of the cavity to be used is essentially determined by the shape of the connecting element.
- the fixing element forms a ball, a cylindrical roller, a rod-shaped element or an annular element.
- a separate fixing element as a connecting element can be used on a variety of existing or special components to be manufactured.
- a plurality of rolling elements are inserted into a cavity to ensure the required radial power transmission. It is also possible to use rod-shaped fixing elements, if appropriate also with a crimping tion along its axial extent.
- annular fixing element which consists of either a closed ring, a ring with a parting line or ring segments.
- the outer ring consists of two rings. For manufacturing reasons, it is advantageous if the two rings are identical with respect to their basic form.
- bearing rows of the rolling bearing form roller bearings. These have the necessary carrying capacity, e.g. to be used in a storage concept.
- bearing rows of the bearing can transmit both axial and radial forces.
- at least one bearing row forms an axial cylindrical roller bearing and at least one bearing row forms a radial cylindrical roller bearing.
- two adjacent rows of bearings form a double row tapered roller bearing.
- at least one bearing row can form a tapered roller thrust bearing and at least one bearing row a radial cylindrical roller bearing.
- the rolling bearing is used as rotor main bearing in a wind turbine.
- the inventive rolling bearing in particular as a storage concept, can be used as a rotor main storage, and are manufactured with correspondingly large diameters simple, inexpensive and reliable.
- An advantage of the method according to the invention for producing an outer ring of a multi-row roller bearing according to the invention is that the at least two rings can be hardened independently of one another.
- the shaping production of the outer ring may well include a simultaneous processing of at least two rings.
- PHg prior to hardening of the rings of the outer ring a division of the first one-piece outer ring in at least two rings.
- the at least two rings of the outer ring can also be made separately.
- each ring has at least one raceway
- the rings must be machined to ensure coaxiality of the raceways. This can be done, for example, by first of all machining the end faces of the rings, ie, for example, by inserting the depressions or bores. After hardening of the rings, the end faces are ground and the rings are assembled, wherein the connecting element of the contact surface of the adjacent ring engages in the cavity of the contact surface and the rings radially centered are. Then the rings are connected to each other by fastening screws and the raceways ground. The processing of the outer circumferential surface of the outer ring can now be done.

- Fig. 1 shows a double-row tapered roller bearing according to the prior art.
- the tapered roller bearing essentially consists of an outer ring 1, a plurality of rolling elements 2 and a divided inner ring with the rings 3 'and 3 ".
- the rolling elements 2 roll on raceways of the outer and inner ring and are guided by cage elements 4.
- the rings 3 'and 3 "of the inner ring are spaced by a spacer ring 5.
- the outer ring 1 can be connected by bores 6 'to a connecting construction.
- Fig. 2 shows a schematic representation of a first embodiment of the rolling bearing according to the invention. Shown in Fig. 2 a) is a plan view of the outer ring 1 in the axial direction. Four exemplary holes 6 are shown, which can serve, inter alia, to connect the outer ring 1 to a connecting construction. 2 b) shows a sectional view of the outer ring 1, it being understood that this consists of two rings 1 'and 1 " right ring 1 "formed and engages in a corresponding cavity with rectangular cross-sectional profile of the left ring 1 'a.
- the connecting element 8 is in radial movement tion outside the raceways 7 in order to avoid weakening of the rings V and 1 "in the region of the raceways.

- the outer ring is supported only by the right-hand ring 1 "in the adjacent construction 10.
- Also shown schematically are forces which act on the outer ring as a result of the rolling elements rolling in.
- Both forces F and F consist of radial components FR 'and FR "and axial components FA 'and FA ", respectively.

- the at least one connecting element 8 engages in a circumferential groove, it is ensured that a radial force transmission between the rings 1 'and 1 "can be made uniform over the entire circumference of the outer ring. This is a significant advantage over a solution with only a few circumferentially distributed cavities and corresponding connecting elements, because in that case a radially acting force could bend the unsupported ring radially outward between two adjacent cavities. Disadvantages in terms of load distribution would be the result.

- the connecting element 8 is formed in this embodiment by a separate fixing element.
- These are cylindrical rollers which are inserted free of play into corresponding cavities of the contact surfaces. Even if several separate recesses for receiving the cylindrical rollers would be possible, a circumferential groove with V-shaped cross-sectional profile has been introduced into both contact surfaces for manufacturing reasons.

- the ring itself (eg also from segments) itself has a square cross-section.
- Fig. 5 shows a schematic representation of a fourth embodiment of the rolling bearing according to the invention. Shown again is a sectional view similar to that of FIG. 2 b), which is why reference is made to the description of FIG. 2 b) with regard to the basic construction.
- the connecting element 8 is again formed in this embodiment by a separate fixing element. These are balls, such as those used in ball bearings. To ensure that the two rings V and 1 "lie free of play on their contact surfaces, the respective cavities are slightly elliptical, so that between the balls and the contact surfaces at the radially in the radial direction. There is some play in the game.
- Fig. 6 shows a schematic representation of a fifth embodiment of the rolling bearing according to the invention.
- the outer ring consists of the three rings 1 ', 1 "and 1'".
- the connecting element 8 is formed by a separate fixing element. Only the two axially outer rings 1 'and 1 "have raceways 7. Consequently, only these outer rings are through-hardened or case-hardened and have the necessary hardened raceway surface 7.
