Definitions
- the present invention relates to a device for converting a rotational movement into a truncated cone or a cylinder and a self-rotating movement of a working lever or vice versa a defining a truncated cone or a cylinder and self-rotating movement of a working lever into a rotational movement, as described in the preamble of independent patent claim 1 is defined.
- a propeller In turbomachines, such as ship drives, the propeller is the preferred flow-generating element today.
- a propeller is a device attached to a rotating axis, which protrudes radially from the axis circumference.
- Suitable propeller designs produce different effects that correspond to the respective requirements.
- propeller blades are used that protrude crookedly from the plane of rotation. When rotating, the medium in which the propeller moves slides from the cutting edge of the propeller blades over their surface because the resilient medium pushes the previous one away. This process is interrupted if, for example, air reaches the propeller in the water. The entire built-up pressure structure collapses due to the thinner air and has to be rebuilt again.
- WO 01/01017 discloses a device for converting a rotational movement into a cone-defining and self-rotating movement of a work lever, or vice versa, a cone-defining and self-rotating movement of a work lever into a rotational movement, in which the work lever is mounted in a lever-bearing element so that it cannot rotate.
- a rotatable rotary element is coupled to the working lever or the lever bearing element.
- the movement conversion is made possible in that the lever bearing element is pivotable about a pivot axis and rotatable about a bearing rotation axis perpendicular to the pivot axis, and the bearing rotation axis and the pivot axis have a common intersection.
- a disadvantage of this device for converting motion is the relatively complicated mechanical structure, in particular as regards the mounting of the lever bearing element.
- the central arrangement of the working lever in the lever bearing element and the lever bearing element itself it cannot have a plurality of working levers.
- a mixer is known in which a rotational movement is converted into a cone-defining and a self-rotating movement of a mixing stick.
- the mixing stick is mounted on the one hand in a rotating element and on the other hand can be pivoted in another bearing part so that it can rotate itself.
- the mixing stick When rotating the mixing stick conically the latter performs its own rotation in the opposite direction, which is brought about by a gear wheel attached to the mixing stick, which rolls inside a ring gear.
- the self-rotation in the opposite direction has a higher rotational speed than the conical rotation, which does result in a good mixing effect, but is disadvantageous for other applications, for example as a drive for a watercraft or aircraft.
- a device for converting motion of the type mentioned at the outset is to be created, which can be used for a wide variety of applications and is mechanically simple. It should preferably have several working levers.
- a device for converting a rotational movement into a truncated cone or a cylinder and a self-rotating movement of a working lever or vice versa a self-rotating movement defining a truncated cone or a cylinder into a rotational movement comprises a around an axis of rotation Rotatable lever bearing element in which the working lever is mounted so that it can rotate about its own axis of rotation.
- a rotatable sun gear is arranged around the axis of rotation, with which a sun gear on the work in the case of a planet gear which is arranged in a rotationally secure manner, is coupled via a transmission means, so that when the lever bearing element rotates about the axis of rotation, the working lever, on the one hand, makes a rotation in the same direction of rotation due to the bearing in the lever bearing element and, on the other hand, self-rotates about that due to the planet gear coupled to the sun gear via the transmission means Axis of rotation in the reverse direction of rotation.
- the rotation blocking of the sun gear leads to two overlapping rotational movements of the working lever when the lever bearing element rotates.
- the working lever rotates with the lever bearing element due to the bearing in the lever bearing element.
- the working lever carries out a self-rotation caused by the planet gear, the planet gear being rotated in the opposite direction to the rotation of the lever bearing element due to the rotation of the lever bearing element about the axis of rotation by the transmission means and the rotationally blocked sun gear.
- the result of the two overlapping, opposite rotational movements of the work lever is that the resulting rotational movement of the work lever has a lower rotational speed than the lever bearing element.
- the lever bearing element supporting the working lever can be constructed more simply in comparison to the device disclosed in WO 01/01017, in particular it does not have to be designed to be pivotable.
- the working lever it is not necessary for the working lever to pass through the center of the lever bearing element and the tip of a cone defined by the movement of the working lever, so that the device according to the invention can have several working levers, which are mounted in the same lever bearing element, which leads to a considerable expansion of the variety of potential applications.
- the working lever performs a self-rotation of 180 ° when the lever bearing element rotates through 360 °.

- the device according to the invention has at least two working levers, each with a planet gear, the planet gears are coupled to the sun gear via transmission means.
- two working levers with suitable working devices a directed flow or a drive in a desired direction can be generated much better than with only one working lever.
- two or more working levers prove to be advantageous since the working devices of the various working levers can feed the mixed material in opposite directions to one another.
- the device according to the invention also has at least two working levers, each with a planet gear, but here each planet gear is coupled via a transmission means to a separate sun gear arranged around the axis of rotation.
- This makes it possible to set the self-rotating position of each working lever separately, which can be used to change the drive direction or the direction of the generated flow.
- this individual adjustment option can also make the airframe suitable for gliding flights, which is very important, for example, in the event of an engine failure during the flight.
- mixing and / or stirring devices other mixing and / or stirring effects can be achieved by adjusting the self-rotating position of a working lever.
- the planet gears of the working levers or the sun gears can each have the same or a different number of teeth, or different rotational transmission ratios can exist between the planet gears and the sun gear or the sun gears. depending on what should be done.
