Drive comprises a lubricating device (6) having a lubricating channel (7) for supplying a lubricant to a section (8) of the first drive element (4) and/or the section (9) of a second drive element (5) when the rotor blade (2) is in a preferred working position and a control device for controlling the lubricant supply through the lubricant channel depending on the interaction of the drive elements. Independent claims are also included for the following: (1) Rotor used in a wind power installation; and (2) Wind power installation with the above rotor. Preferred Features: The control device has a free switch for switching the supply through the channel when the drive elements interact with their sections and the lubricant supply blocks the channel when the sections are not interacting. |
