| 20100160138 | Mounting Means For Mounting A Device With A Rotor - A mounting means is provided for mounting a device comprising at least one mounting shield, a pivot bearing arranged in the mounting shield and a rotor mounted perpendicularly in the pivot bearing, an axis of rotation of the rotor being oriented substantially perpendicularly when the device is mounted on the mounting means, and the mounting means having resilient properties. In one embodiment, the resilient properties of the mounting means are direction-dependent, in particular orthotropic. As a consequence of the direction-dependent resilient properties of the mounting means, oscillations excited by a rotary movement of the rotor strike a mounting, the pivot point of which does not coincide with the axis of rotation of the rotor, but is set apart therefrom. This makes it much more difficult to excite the mounting means to form unstable oscillations, so that such oscillations are effectively damped. | 06-24-2010 |
