Abstract
A set () of yaw claws () is provided comprising at least a first yaw () claw and a second yaw claw (). The first yaw claw () is to be used in a bearing ring () of a first yaw bearing () and the second yaw claw () in a bearing ring () of a second yaw bearing (). A circumference of the bearing ring () of the first yaw bearing () is substantially different from a circumference of the bearing ring () of the second yaw bearing (). Each yaw claw () has a periphery, formed by a first side end (), a second side end (), an inner arc () and an outer arc (), the inner arc () and the outer arc () being concentric with the respective bearing ring (). At least two spring packs () are provided for pre-tensioning the yaw claw (), respective spring pack centres () of the at least two spring packs () being arranged on a spring pack centreline () that is concentric with the inner arc () and the outer arc (). A length of the spring pack centreline (), measured from the first side end () to the second side end (), of the first yaw claw () is substantially equal to a length of the spring pack centreline () of the second yaw claw ().
