The second spacer element Includes at least two curved pieces which are placed circumferentially in opposition to one another. The second spacer element extends in the radial direction such as to from a radial gap to the first spacer element and includes an oil supply channel which runs in the radial direction.

A system for a wind turbine nacelle having a shaft housing, a blade shaft that extends through the shaft housing and is rotatable relative to the shaft housing, a blade holder connected to the blade shaft, and an outer bearing between the blade shaft and the shaft housing includes a conical spring. The conical spring engages a portion of the outer bearing to exert a preload force on the outer bearing. The system further includes a backstop surrounding the blade shaft and having an interference fit with the blade shaft and a pin extending through the blade shaft and the blade holder. The pin is positioned to prevent the blade shaft from moving relative to the backstop.

A fluid film bearing for a rotor hub of a wind turbine is provided including a first part and a second part rotatably coupled to each other about a longitudinal axis. The first part includes an annular first sliding surface extending in the circumferential direction of the fluid film bearing along the first part. In addition, the second part includes a support structure and a first group of bearing pads coupled to the support structure and having a bearing pad sliding surface configured to slide on the first sliding surface. In addition, the support structure includes a plurality of openings for replacing the bearing pads.

A fatigue-resistant load-bearing steel for a wind turbine main shaft, and a manufacturing method and a use thereof are provided. The manufacturing method includes: step S1, smelting: smelting a raw steel into a molten iron, followed by impurity removal and deoxidation, and adjusting contents of respective components to obtain a casting molten steel; step S2, continuous casting: crystallizing the casting molten steel with an electric pulse, followed by solidification to obtain a continuous casting billet; step S3, rolling: subjecting the continuous casting billet to rough rolling and finish rolling sequentially to obtain a finish-rolled billet; and step S4, post-rolling treatment: slowly cooling and then air-cooling the finish-rolled billet to obtain the fatigue-resistant load-bearing steel.

A bearing assembly for a pitch tube of a wind power plant includes a transmission shaft, a bearing cartridge for mounting and sealing the pitch tube with respect to the transmission shaft, a fastening flange which is configured by the transmission shaft or by the pitch tube for fastening the bearing cartridge in a non-rotational manner, and an insulation element which is fastened via a first fastening element to the fastening flange and via a second fastening element to the bearing cartridge for the electrical insulation of the pitch tube with respect to the transmission shaft. With the aid of the bearing cartridge which is fastened in an electrically insulating manner by the insulation element, a mechanically and electrically operationally reliable passage of the pitch tube through the transmission of a wind power plant is made possible in an inexpensive and simple manner.

A wind turbine planet gear shaft has a shaft body with an outer surface, a segment of the outer surface being a slide bearing surface configured to form a radial slide bearing with an inner opening of a planet gear. The slide bearing surface has a first portion configured as a non-load-bearing zone and a second portion configured as a load-bearing zone and exactly one axially elongate oil pocket in the slide bearing surface, that oil pocket being located in the non-load-bearing zone. An oil supply channel in the shaft body has a first end in communication with the oil pocket, and first and second oil return channels in the slide bearing surface each have a first end at a longitudinal end of the oil pocket and a second end open to ambient air.
