Document Type and Number:
Japanese Patent JP2014517203
Kind Code:
A
Abstract:
Braking devices for wind turbines having a vertical axis are disclosed. An example braking device includes a flap able to tip about a tipping axis. The example flap has a center of gravity positioned outside the tipping axis. In addition, the example braking device disclosed herein includes a torque limiter having a disengagement torque. In addition, the example flap is mounted on the torque limiter, and the torque limiter is to allow the flap to tip through a tipping angle about the tipping axis for a rotational speed of the flap about the vertical axis which induces a torque at the torque limiter greater than or equal to the disengagement torque.
