  • Patent number: 11655852
    Abstract: The invention relates to a sliding bearing having a first bearing component and a second bearing component, which are arranged such that they can rotate relative to each other in a rotation direction (RR) about a rotation axis (RA), wherein at least two sliding segments (1) are arranged between the first bearing component and the second bearing component, wherein the at least two sliding segments (1) each have a support structure (2) for fixing the sliding segment (1) to the first or second bearing component, and a sliding surface (3) for bringing the sliding segment (1) into sliding contact with the second or first bearing component, wherein the sliding surface (3) has, in the rotation direction (RR), a front leading edge (4) and a rear trailing edge (5), wherein the sliding surface (3) has an oil distribution groove (6), which is arranged directly adjacent to the front leading edge (4), and wherein the sliding segment (1) has a passage opening (7) for supplying the oil distribution groove (6) with oil, w

  • Patent number: 11635063
    Abstract: A bearing assembly of a rotor of a wind turbine, for mounting a shaft of the rotor in a fixed housing, wherein the shaft of the rotor is coupled to rotor blades of the rotor via a hub, includes: a plurality of first housing-side axial slide bearing segments engaging on the housing; a plurality of second housing-side axial slide bearing segments; a plurality of first housing-side radial slide bearing segments; and a plurality of second housing-side radial slide bearing segments. An axial distance between the first and second axial sliding surfaces of the rotor defines a bearing length l. The radial sliding surfaces of the rotor on which the first and second radial slide bearing segments are supported, define a bearing diameter d of the bearing assembly, and V?1 applies to a ratio V=l/d between the bearing length l and the bearing diameter d.

  • Patent number: 11346396
    Abstract: A bearing assembly for supporting a rotor in a fixed housing includes multiple slide bearing segments, each having a slide bearing body supported against a sliding surface. In the region of each slide bearing segment, the bearing clearance between the respective slide bearing body and the sliding surface is adjustable by an adjustment screw, each adjustment screw having an outer thread via which the screw can be screwed into a recess having an inner thread, each adjustment screw having a groove delimited on both sides by adjustment screw sections. A clamping screw extends through the adjustment screw sections and also through the groove, the adjustment screw sections can be clamped by the clamping screw, whereby each adjustment screw can be secured in the respective recess.

  • Patent number: 10584685
    Abstract: A wind turbine, including a support structure and a thrust bearing having a bearing pad which includes a piston and which is movably connected to the support structure, a spring element which is configured to resiliently support the bearing pad relative to the support structure, wherein a pad portion of the bearing pad and/or the bearing pad itself is configured to tilt and to move translationally relative to the support structure, and wherein a gap is provided between the piston and the support structure. The piston limits the movement of the bearing pad. Thus, reliable and well defined movement limits are provided. Furthermore, a broad spectrum of spring parameters is available since the movement may be restricted by the piston and not necessarily be the spring element.
