摘要:
A drive operator is described for moving a movable barrier, comprising an electric motor (10) with a rotatable shaft (20) about an axis (X) and coaxially coupled to a first rotatable disc (60), and - a second disc (90) coaxial to the first that from it can receive rotary motion to be transmitted to the barrier. To improve the torque transfer and simplify the structure the first and second disc comprise mutually facing surfaces on each of which there is present a plane (64, 92) inclined relative to a plane perpendicular to said axis, the inclined plane of a disc being shaped to push along said axis the inclined plane of the other disc following a rotation.

A device configured to actuate a driven member by driving a driving motor (11) includes a brake which does not consume electric power and which can be easily mounted in the device. A speed reducer is mounted in the device, and includes a reduction mechanism (2) for transmitting the rotation of the driving motor (11) toward the driven member after reducing its speed, and a locking type reverse input shutoff mechanism (3), as the brake, which is configured to mechanically lock up when reverse input torque is applied from the driven member while the driving motor (11) is not being driven, thereby retaining the position of the driven member. The reduction mechanism (2) and the reverse input shutoff mechanism (3) are combined to constitute a single unit.
摘要:
The turbine has a rotor, and a drive train connected to a generator for generating electric power by the rotation of the drive train. A braking device (43) decelerates drive train components (44) of the drive train. The braking device comprises an electronic wedge brake with an electronic braking force control. A control unit (61) is utilized by the braking force control to actively counteract vibrations of the power train components during operation. The drive train has shafts as the drive train components connected with each other via a transmission gear (33). An independent claim is also included for a method for braking drive train components of a drive train of a wind turbine.

Provided is a clutch unit in which an output-side outer ring member is attached to a base plate without welding. A clutch unit (100) includes an output-side clutch (60) and a housing (11) that accommodates the output-side clutch (60). The output-side clutch (60) includes an output-side outer ring member (62). The output-side outer ring member (62) and the housing (11) have an engagement protrusion (62s) and an engagement groove (11s) that engage with each other to restrict relative rotation therebetween.
