Bearing and braking system for the nacelle of a wind turbine

摘要

The device has a bearing (9) arranged on the bearer tower (1) on which the machine head (2), which has a rotor, is rotatable about a vertical axis and a clamping device for locking the machine head on the tower in a desired rotary position. Devices in the form of a hydrostatic bearing have a high pressure pump for generating a pressure fluid film (22) between the clamping surfaces of the clamping device.
