A main shaft assembly of a wind turbine (10) includes a main shaft (34) secured to a bedplate (48) of the wind turbine (10) and a bearing (54, 58) seated within the bedplate(48). The bearing (54, 58) is held in place via a cover (68) that is secured to a mounting surface (49) of the bedplate. Moreover, the bearing (54, 58) includes an inner race (56, 64), an outer race (55, 62), a plurality of roller elements (57, 66) arranged therebetween. In addition, the bearing (54, 58) engages the main shaft (34) so as to provide rotation thereof. The main shaft assembly further includes a flexible member (72) arranged between the outer race of the bearing (54, 58) and the cover (68). As such, when the flexible member is compressed, a gap between the mounting surface of the bedplate (48) and the cover (68) is reduced or closed.

A nacelle of a wind turbine, the nacelle comprising a rear frame structure (1) comprising a plurality of truss members (2), and a plurality of pivot joints (3). Each pivot joint (3) interconnects ends of at least two truss members (2), thereby forming a truss structure with the pivot joints (3) arranged in node points of the truss structure. At least some of the pivot joints (3) are adjustable in such a manner that an angle between two truss members (2) being interconnected via a pivot joint (3) is adjustable by means of the pivot joint (3). Nacelles of varying dimensions can be provided using a limited number of basis components in the form of truss members (2) and pivot joints (3). The pivot joints (3) are moment neutral, and therefore bending moments are not introduced into the truss members (2).

A method for mounting or dismounting a wind turbine component of an energy generating unit in a multirotor wind turbine is disclosed. The multirotor wind turbine comprises a tower configured to support one or more load carrying structures each arranged for supporting at least two energy generating units arranged at or near its ends and at opposite sides of the tower. The method comprises positioning or dispositioning a first wind turbine component at a first end of the load carrying structure, yawing the load carrying structure approximately 180 degrees, and positioning or dispositioning a second wind turbine component at the second end of the load carrying structure opposite the first end. The method may be used in erecting or servicing a multirotor wind turbine.

A vertical axis hydrokinetic turbine apparatus comprises a drive shaft assembly, at least two blade assemblies, and at least two pairs of support arm connection interfaces. The drive shaft assembly comprises a rotatable drive shaft, an upper and lower center plates fixedly mounted to upper and lower ends of the drive shaft. Each blade assembly comprises a main blade having a longitudinally elongated body with a foil profile configured to produce lift in the presence of flowing water; and first and second support arms each having a longitudinally elongated body extending away from the main blade and terminating at a drive shaft connecting end. Each pair of support arm connection interfaces serve to releasably connect one of the blade assemblies to the drive shaft assembly and comprises upper and lower center plate components on the upper and lower center plates respectively, and support arm components on each of the first and second support arms. Each of upper and lower center plate components are configured to releasably connect to either of the support arm components, thereby enabling the blade assembly to be mounted to the drive shaft assembly in a clockwise rotation configuration wherein a leading edge of the main blade faces a clockwise rotation direction of the drive shaft, and in a counter-clockwise rotation configuration wherein the blade assembly is inverted 180° to the clockwise rotation configuration and wherein the leading edge of the main blade faces a counter-clockwise rotation direction of the drive shaft.
