Abstract: In a first aspect, a roller pitch bearing for a wind turbine is provided. The roller pitch bearing comprises a first bearing component and a second bearing component, the first bearing component being configured to rotate with respect to the second bearing component; wherein one of the first and the second bearing components is configured to be coupled to a wind turbine blade and the other one of the first and the second bearing components is configured to be coupled to a rotor hub of a wind turbine. The roller pitch bearing further a limiting structure attached to the first bearing component, the limiting structure radially extending from the first bearing component towards the second bearing component to limit a radial movement between the bearing components. In further aspect, a rotor for a wind turbine comprising a roller pitch bearing is provided.

Abstract: A hub assembly or a rotor of a wind turbine includes a hub having openings to connect rotor blades thereto. The hub assembly includes a pitch bearing (3) and a pitch carrier positioned between the hub and the pitch bearing, the pitch carrier configured to support a pitch system for adjusting a blade pitch of the rotor blades. The pitch carrier includes a strip plate arranged between two opposite regions of a perimeter of the opening. A mounting structure attaches the strip plate to the hub.

Abstract: Hub assemblies (1) for a rotor (115) of a wind turbine (160) are disclosed. The hub assembly comprises a hub (11) comprising openings (12) to connect rotor blades (120), a pitch bearing (3), a pitch carrier (2) positioned between the hub (11) and the pitch bearing (3) and configured to support a pitch system (4) for adjusting a blade pitch, wherein the pitch carrier (2) comprises a strip plate (21) arranged between two opposite regions of the perimeter of the opening (12), and a mounting structure for assembling the strip plate (21) with the hub (11). Also disclosed are methods (200) for manufacturing a hub assembly (1) of a wind turbine (160).
