Abstract
An auxiliary drive system for driving a wind turbine component is described. The drive system includes a motor, gearing operationally connected with the motor, and an actuator operationally connected with the gearing for actuating the wind turbine component. The auxiliary drive system is provided with one or more locks. The one or more locks are able to interlock with a component of the gearing to lock the auxiliary drive system.
Claims19
An auxiliary drive system for driving a wind turbine component, the auxiliary drive system comprising:
- a motor;
- an actuator for actuating a wind turbine component;
- reduction gearing operationally connected with the motor to be driven by the motor and operationally connected with the actuator for driving the actuator;
- and
- a first lock and a second lock, the first and second locks each comprising a locking element that assumes a first position or a second position, the first and second locks in the first position interlocking with a component of the reduction gearing to lock an auxiliary drive system, and the first and second locks in the second position not interlocking with the reduction gearing.
An auxiliary drive system for driving a wind turbine component comprising:
- a motor;
- an actuator for actuating the wind turbine component;
- reduction gearing operationally connected with the motor to be driven by the motor and operationally connected with the actuator for driving the actuator;
- a lock that includes a first and a second locking element, the first and second locking elements assuming a first position to interlock with a component of the reduction gearing to lock the auxiliary drive system, or a second position to not interlock with the reduction gearing.
An auxiliary drive system for driving a wind turbine component comprising:
- a motor;
- an actuator for actuating the component;
- reduction gearing operationally connected with the motor to be driven by the motor and operationally connected with the actuator for driving the actuator;
- and
- an eccentrically mounted lock having a locking element that assumes a first position to interlock with a component of the reduction gearing to lock the auxiliary drive system or a second position in which the locking element does not interlock with the reduction gearing.
