Wind turbine and pitch bearing of the wind turbine

A pitch bearing comprising:

• at least two rings, each of the at least two rings being attached to a first or second wind turbine component, the first wind turbine component being a blade and the second wind turbine component being hub;
• and
• at least one bearing reinforcement attached to at least one of the two rings,
• wherein the at least one bearing reinforcement comprises a bearing reinforcement thickness that is variable along a circumferential direction of the pitch bearing,
• wherein the at least one bearing reinforcement comprises two ends and a central part disposed between the ends in a circumferential direction of the pitch bearing wherein the bearing reinforcement thickness of the at least one bearing reinforcement is variable along the circumferential direction of the pitch bearing from the ends towards the central part of the at least one bearing reinforcement, wherein a ratio between a maximum bearing reinforcement thickness and a bearing thickness is at least 15%, and
• wherein the at least one bearing reinforcement is attached to at least one of the two rings such that, in use, the at least one of the two rings is disposed, along the axial direction of the pitch bearing, between the at least one bearing reinforcement and the wind turbine component to which the at least one of the two rings is attached.
