- the invention relates to a rolling bearing, in particular for a rotary joint of a wind turbine, comprising an outer ring, an intermediate ring and an inner ring, wherein between the outer ring and the intermediate ring and between the intermediate ring and the inner ring in each case at least one layer is arranged with Wälzköpern, so that the outer ring is mounted rotatably against the intermediate ring on the one hand and the intermediate ring against the inner ring on the other hand.
- the invention relates to a method for producing a corresponding rolling bearing.
- the present invention seeks to provide an advantageous designed rolling bearing and a method for producing a corresponding rolling bearing.
- a rolling bearing presented here is, in particular, a slewing bearing for a rotary joint of a wind power plant and preferably a slewing bearing with a diameter in the range of 0.5 m to 4 m.
- the rolling bearing comprises an outer ring, an intermediate ring and an inner ring, wherein between the outer ring and the intermediate ring and between the intermediate ring and the inner ring each having at least one layer is arranged with rolling elements, so that the outer ring against the intermediate ring on the one hand and the intermediate ring against the inner ring on the other hand rotatably mounted.
- the outer ring and / or the inner ring is connected to a toothed segment, which covers one end of a filling channel in the outer ring or inner ring.
- the toothed segment is in this case provided as part of an adjusting device to which a servomotor is flanged, so that in this way a rotary joint with controllable rotational position is realized.
- a rotary joint is used for example in a wind turbine to adjust the rotational position of the so-called nacelle relative to the tower or to control the blade position of the rotor blades relative to the hub.
- the outer ring, the intermediate ring, the inner ring, the Rolling and the toothed segment produced in their own production process and subsequently joined together as part of an assembly process.
- the filling channel serves to introduce the rolling elements into the intermediate space between the outer ring or the inner ring and the intermediate ring.
- the toothed segment is connected to the outer ring or the inner ring, whereby the filling channel is covered and thus closed.
- the solution proposed here offers the advantage that the filling channel typically required for the production of the rolling bearing does not must be guided by the gearing. Since very high qualitative demands are made on the toothing in particular, a corresponding passage of the filling channel through the toothing tends to be unfavorable.
- Another advantage is a variant of the rolling bearing, in which at least one layer is arranged with rolling elements between the outer ring and the intermediate ring concentric and coaxial with at least one layer with rolling elements between the intermediate ring and the inner ring.
- at least two layers are arranged with rolling elements in the radial direction offset from one another, whereby the rigidity of the rolling bearing is increased.
- the rolling bearing is also designed such that the layers with rolling elements each have crossed lines of pressure.
- a corresponding storage of rolling elements with crossed printing lines is described in detail in the applicant's WO 2010/037370 A1 and the entire contents of this document is hereby incorporated by reference.
- the variants mentioned therein for the storage of rolling elements with crossed pressure lines are in principle suitable for a rolling bearing proposed here and are accordingly used depending on the application for the rolling bearing.
- a variant is preferred in which at least one layer of rolling elements is formed by balls in a four-point bearing.
- each layer is formed with rolling elements each by balls in a four-point position.
- the filling channel is provided with a filling. This not only prevents individual rolling elements can get out of their intended trajectory, but also ensure that the corresponding outer ring or inner ring in the region of the filling channel is about as strong as in the other areas.
- the filling is introduced into the filling channel in a separate production sub-process, after the rolling elements have been introduced into the corresponding intermediate region between outer ring or inner ring and intermediate ring.
- the toothed segment is formed as a ring body, which preferably has a toothing which extends over an angular range ⁇ 360 °.
- the angular range over which the toothing extends is typically adapted to the respective application. So if an adjustability over an angular range of 180 ° is desired, it is sufficient to carry out the toothing over an angular range which is slightly greater than 180 °.
- the rolling bearing wherein the toothed segment is fastened by means of a screw on the outer ring or on the inner ring. Due to such a releasable attachment, it is possible, if necessary, ie in the case of a present damage, replace the toothed segment individually. Accordingly, in such a case, not the complete rolling bearing must be replaced, but only the actually damaged component, namely the toothed segment.
- the stated object to provide an advantageous method for producing a corresponding rolling bearing is achieved by a method according to claim 10. The method is used in particular for producing a roller bearing of one of the aforementioned embodiments, wherein a corresponding rolling bearing comprises an outer ring, an intermediate ring and an inner ring.
- At least one layer with rolling bodies is arranged between the outer ring and the intermediate ring and between the intermediate ring and the inner ring, so that the outer ring is rotatably mounted relative to the intermediate ring on the one hand and the intermediate ring against the inner ring in the final assembly state.
- a filling channel is incorporated in the outer ring and / or in the inner ring for the arrangement of at least one layer with rolling elements, through which the rolling elements are introduced in the context of an assembly process step in the space between the outer ring and the inner ring and the intermediate ring.
- the filling channel is provided with a filling and as a result the outer ring or the inner ring is connected to a toothed segment, wherein the toothed segment covers one end of the filling channel provided with the filling.
