摘要： A support apparatus for a shaft system. The shaft system comprises a first shaft (1), a second shaft (2), and a bearing (3) arranged between the first shaft (1) and the second shaft (2); the first shaft (1) is sleeved at an outer peripheral side of the second shaft (2) and is able to rotate relative to the second shaft (2) by means of the bearing (3). The support apparatus is used for arranging at a first end in an axial direction of the shaft system, and the support apparatus comprises: shaft end support members (8, 15), at least a portion of the shaft end support members (8, 15) being rotatably supported in an axial direction at an outer side of a shaft end face of a first end of the second shaft (2); and connection assemblies (17, 14), where the connection assemblies (17, 14) in the axial direction of the shaft system are used for being connected between a first end of the first shaft (1) and the shaft end support members (8, 15). Further disclosed is a wind turbine. The present support apparatus may enable a bearing of a shaft system to essentially not bear a load or reduce an axial load borne, and the service life of the bearing is prolonged.

摘要： A main bearing housing for supporting a main rotor shaft of a wind turbine, wherein the main bearing housing defines a first end, a second end and a floor region intermediate the first and second ends. The main bearing housing comprises a first bearing arrangement positioned at the first end of the main bearing housing, a second bearing arrangement positioned at the second end of the main bearing housing, wherein the floor region includes a first oil sump positioned at the first bearing arrangement, and a second sump positioned at the second bearing arrangement. Advantageously, the embodiments of the invention provide that the bearings of the main bearing housing are lubricated by a lubrication system that includes sumps positioned at each of the fore and aft bearings of the main rotor shaft. The fore and aft bearings are therefore supplied with oil at suitable lubrication points and are part of the lubrication system that supplies oil to other components in the wind turbine that require oil lubrication, for example the gearbox and/or the generator bearings. The fore and aft bearings of the main bearing housing therefore do not require a separate lubrication system, such as a grease-based system and so the overall lubrication requirements for the nacelle are simplified.

摘要： A wind power plant which is equipped with novel elastic self-aligning ball bearings. The self-aligning ball bearings can, in principle, be used for the cardanic suspension of a pendulum absorber, preferably in a tower of a wind power plant, as well as for rope attachment of floating off-shore plants at the bottom of a body of water. Correspondingly equipped vibration pendulum absorbers per se and to corresponding installations and pendulum absorbers, which have additional damping devices, are disclosed.

摘要： For replacing in particular a used main bearing of a wind turbine, a bearing housing is first pulled axially off the main bearing along a rotor shaft, then the used main bearing is divided and disassembled. A new main bearing is assembled around the rotor shaft and the original bearing housing is pushed axially back onto the main bearing. During the replacement of the main bearing, the rotor shaft is supported on a machine carrier by means of a holding device, wherein the holding device is arranged at least partially in the region between a bearing seat and a hub-side end region of the rotor shaft.

摘要： A method of lubricating a main bearing of a wind turbine, the method comprising providing the main bearing. The main bearing comprises a main bearing housing having one or more pre-existing lubrication ports, an outer race, an inner race radially disposed inwardly from the outer race, and a first row of roller bearings and a second row of roller bearings. The first and second rows of roller bearings are radially disposed between the inner race and the outer race. The first row of roller bearings is axially disposed on the upwind side of the second row of roller bearings. The method includes forming one or more alternate lubrication ports in the main bearing housing. The alternate lubrication ports are configured to deliver a lubricant between the first row of roller bearings and the second row of roller bearings.

摘要： Provided is a roller bearing which includes rollers (4, 5) interposed between raceway surfaces of inner and outer rings (2, 3) and having a roller outer circumferential surface, and a DLC film on the roller outer circumferential surface. The DLC film includes a metal layer, an intermediate layer containing the metal and DLC, and a superficial layer containing DLC, in the stated order starting from a side adjacent to a substrate of the rollers (4, 5). The intermediate layer has a bilayered structure of a top layer and a bottom layer. The top layer is a DLC-enriched layer having a greater content of DLC than the bottom layer. The bottom layer is a metal-enriched layer having a greater content of the metal than the top layer. The metal-enriched layer has a layer thickness of between at least 100 nm and no more than 300 nm.
