DRIVE MECHANISM FOR ADJUSTING THE ROTOR BLADES OF WIND POWER INSTALLATIONS
专利汇可以提供DRIVE MECHANISM FOR ADJUSTING THE ROTOR BLADES OF WIND POWER INSTALLATIONS专利检索，专利查询，专利分析的服务。并且A device for adjusting rotor blades (1) which are mounted on a rotor hub of a wind power installation in such a way that they can rotate has a drive mechanism (12) for turning said rotor blades. The adjustment of the rotor blades can also be used as a braking system, the rotor blades (1) being turned in the direction of the feathering pitch so that the wind power installation loses power or speed, in order to shut down the installation. A reverse blocking mechanism (19) is connected to the rotor blades (1) to ensure that the speed of the installation can be reduced even if the power supply fails. Said reverse blocking mechanism (19) can be activated to prevent the rotor blades (1) from turning back from the feathering pitch to the operating position. The blocking mechanism (19) is deactivated during normal operation and is activated automatically if the power supply fails. The rotor blades (1) are then only able to rotate into the feathering pitch and are maintained there until the installation has come to a stop.，下面是DRIVE MECHANISM FOR ADJUSTING THE ROTOR BLADES OF WIND POWER INSTALLATIONS专利的具体信息内容。
