There are disclosed methods for withdrawal of a bearing from a gate mechanism including a mechanism housing, a carrier assembly, and discrete fasteners. The carrier assembly includes a carrier housing and a carrier bearing. The carrier bearing is supported for rotation within the carrier housing. The carrier housing has a carrier support mating with a receiving bore of the mechanism housing. The carrier housing has multiple flange fasteners aligning with housing fasteners and housing surfaces of the mechanism housing when the carrier housing mates with the receiving bore. Multiple discrete fasteners are removed from a first group of the flange fasteners aligned with the housing fasteners. The carrier assembly is displaced from the mechanism housing in response to inserting the plurality of discrete fasteners to a second group of the plurality of flange fasteners aligned with the plurality of housing surfaces.

A balance shaft includes an unbalanced shaft (3) comprising a bearing journal (8, 9), the periphery of which is merely partially cylindrical. The cylindrical partial periphery (10) of the bearing journal is oriented toward the shaft imbalance. The balance shaft also includes a needle roller cage assembly (15); and a bearing ring (13), which extends around the bearing journal, lies against the cylindrical partial periphery and forms the inner raceway of the needle roller cage assembly. The cage (27) of the needle roller cage assembly is designed to run on the end faces of the bearing ring axially on both sides by means of radially inwardly extending projections.

A bearing arrangement for a wind turbine including a bearing housing and a drive shaft, whereby the drive shaft is arranged within the bearing housing in an axial direction along a longitudinal axis of the bearing housing, the bearing arrangement further includes a downwind bearing and an upwind bearing, whereby the downwind bearing and the upwind bearing are arranged between the bearing housing and the drive shaft, wherein the downwind bearing and/or the upwind bearing is a radial bearing including multiple radial bearing pads, whereby each one of the multiple radial bearing pads is attached to one of a multiple radial bearing bodies of the radial bearing and the multiple radial bearing pads are arranged about the drive shaft is provided.

The invention relates to a foil bearing (10) having at least one foil (16, 18) which is arranged and fixed in place inside a bearing bore (14) of a bearing support (12). The bearing support (12) is made of aluminum or an aluminum alloy, wherein the surface of the bearing bore (14) is provided at least in one contact region (20) of the at least one foil (16, 18) with a hard material layer (26). The bearing support (12) can be produced in a simple and cost-effective manner, has a low weight and a good thermal conductivity.

The invention relates to a foil bearing (10) having at least one foil (16, 18), which is arranged and fixed in place inside a bearing bushing (12). In order to simply the production, in particular assembly, of the foil bearing (10), the bearing bushing (12) has at least two openings (20, 22, 24) offset from each other in the circumferential direction of the bearing bushing (12) or depressions (120, 122, 124) made in the inner lateral surface of the bearing bushing, into which openings or depressions two opposing circumferential end sections (16a, 16b, 18a, 18b) of the at least one foil (16, 18) engage.
