Abstract
A device for the targeted adjustment of the angle of incidence of a rotor blade (13) which is rotatably mounted, at the foot (14) thereof, on a hub (12) of a rotor (11) of a wind power installation (10). The device includes a gearing, a driving toothed wheel (21, 41) that meshes with the gearing (20, 40), and a lubricating device. The lubricating device, due to a temporary displacement of the driving toothed wheel (21, 41) from an operating position into a lubricating position, can be engaged with a defined point of the gearing (20) or the driving toothed wheel (41), respectively previously engaged with the driving toothed wheel (1) or the gearing (20, 40), so as to transfer lubricant.
Claims12
A device for targeted adjustment of an angle of incidence of a rotor blade (13) that is rotatably mounted, at a foot (14) thereof, on a hub (12) of a rotor (11) of a wind power installation (10), said device comprising a gearing (20, 40), a driving toothed wheel (21, 41) that meshes with said gearing (20, 40), and a lubricating device, which comprises a lubricating pinion (22, 42) meshing with the gearing (20) or the driving toothed wheel (41) and provides a lubricant reserve (25, 46) on at least one defined lubricating tooth (24, 44, 45) of the lubricating pinion (22, 42), wherein the lubricating device is configured such that, due to a temporary displacement of the driving toothed wheel (21, 41) from an operating position into a lubricating position, the lubricating device can be engaged with a defined point of the gearing (20) or the driving toothed wheel (41), respectively previously engaged with the driving toothed wheel (21) or the gearing (20, 40), so as to transfer lubricant, and wherein displacement from an operating position into a lubricating position takes place via a control device, this control device being configured to effect the displacement during continuous operation of the wind power installation.
A method for lubrication of a point of engagement of a gearing (20) or a driving toothed wheel (41) with a driving toothed wheel (21) or a gearing (40) of a device for targeted adjustment of an angle of incidence of a rotor blade (13) that is rotatably mounted, at a foot (14) thereof, on a hub (12) of a rotor (11) of a wind power installation (10), said device comprising a gearing (20, 40), a driving toothed wheel (21, 41) that meshes with said gearing (20, 40), and a lubricating device, which comprises a lubricating pinion (22, 42) meshing with the gearing (20) or the driving toothed wheel (41) and provides a lubricant reserve (25, 46) on at least one defined lubricating tooth (24, 44, 45) of the lubricating pinion (22, 42),
- wherein the lubricating device is configured such that, due to a temporary displacement of the driving toothed wheel (21, 41) from an operating position into a lubricating position, the lubricating device can be engaged with a defined point of the gearing (20) or the driving toothed wheel (41), respectively previously engaged with the driving toothed wheel (21) or the gearing (20, 40), so as to transfer lubricant,
- wherein displacement from an operating position into a lubricating position takes place via a control device, this control device being configured to effect the displacement during continuous operation of the wind power installation;
- and
- wherein the lubrication is performed during continuous operation of the wind power installation and within a period of time in which the driving toothed wheel (21, 41) is brought from an operating position into a lubricating position and back again into an operating position.
A wind power installation including a device for targeted adjustment of an angle of incidence of a rotor blade (13) that is rotatably mounted, at a foot (14) thereof, on a hub (12) of a rotor (11) of a wind power installation (10), said device comprising a gearing (20,40), a driving toothed wheel (21, 41) that meshes with said gearing (20, 40), and a lubricating device, which comprises a lubricating pinion (22, 42) meshing with the gearing (20) or the driving toothed wheel (41) and provides a lubricant reserve (25, 46) on at least one defined lubricating tooth (24, 44, 45) of the lubricating pinion (22, 42), wherein the lubricating device is configured such that, due to a temporary displacement of the driving toothed wheel (21, 41) from an operating position into a lubricating position, the lubricating device can be engaged with a defined point of the gearing (20) or the driving toothed wheel (41), respectively previously engaged with the driving toothed wheel (21) or the gearing (20, 40), so as to transfer lubricant, wherein displacement from an operating position into a lubricating position takes place via a control device, this control device being configured to effect the displacement during continuous operation of the wind power installation.
