Definitions
- the invention relates to a turbomachine according to the preamble of patent claim 1;
- a turbomachine is for example by the US 2,509,442 A known as the closest prior art.
- the WO 98/38085 A1 discloses a turbomachine with at least two rotors, which are rotatably mounted in opposite directions about an axis of rotation and on the outside of blades or vanes are arranged, with a rotatably mounted about the same axis of rotation shaft and with a drive mechanism in the form of a transmission for converting a Rotational movement of the shaft in mutually opposite directed rotational movements, ie a Kontrarotation, the rotors and / or vice versa.
- the shaft runs along the axis of rotation of the rotors through it.
- the turbomachine can be used to particular advantage in a marine propulsion system such as a POD, in which the first rotor forms with its blades or blades a first propeller and the second rotor with its blades or blades a second propeller driven by the shaft via the drive mechanism become. Due to the contrarotating second propeller, the lossy swirl of the propeller outflow of the first propeller is partially re-directed and converted into thrust. By such a mechanical torque compensation, the efficiency of the ship propulsion system is improved.
- the shaft can be driven, for example, by an electric motor or an internal combustion engine.
- the torque of the shaft is distributed by the drive mechanism on the two propellers, wherein the rotational speed of the shaft is advantageously selected to be greater than the rotational speed of the two rotors.
- the drive mechanism thus has the function of a reduction gear.
- the turbomachine can also be used particularly advantageously as a turbine, for example for driving a generator.
- the rotors then drive the shaft, wherein the rotational speeds of the at least two rotors are advantageously smaller than the rotational speed of the shaft.
- the drive mechanism then acts as a step-up gear, reducing the moment to be transmitted by the shaft.
- the problem is that the drive mechanism must be accommodated in the relatively small hub. This leads to a high mechanical complexity of the hub.
- the dense construction also leads to problems in storage and lubrication of the bearings, which may affect the reliability of the turbomachine.
- the hub would have to be made larger, but this would be disadvantageous in terms of fluid dynamics and would negate the efficiency advantages of the contrarotating arrangement.
- a turbomachine according to the preamble of claim 1 is known from US 2,509,442 A known.
- the shaft is arranged perpendicular to the housing and therefore protrudes from the housing.
- turbomachine it is an object of the present invention to provide a turbomachine, in which the hydrodynamic advantages of several contra-rotating rotors can be used, but which has a comparatively lower mechanical complexity and component density and thus increased reliability.
- a turbomachine comprises at least two rotors, which are rotatably mounted in opposite directions about an axis of rotation and on which blades or vanes are arranged, a rotatably mounted machine shaft and a drive mechanism which connects the machine shaft with the at least two rotors and a rotational movement the machine shaft in opposite directions directed rotational movements, ie a contrarotation that converts rotors or vice versa.
- a housing forms a channel for a flow of a fluid, wherein the rotors are arranged in the channel in the flow direction of the fluid one behind the other.
- the machine shaft and the rotors are annular and rotatably mounted in the housing, wherein the annular rotors each have an inner ring side and a ring outer side and wherein the blades or vanes are respectively arranged on the inner ring side of the rotors.
- the fluid may be a liquid or a gas.
- the annular design of the rotor it is particularly advantageous possible to dispense with the rotors on a (central) shaft, ie a component that connects the blade or wing ends of a rotor on its side facing away from the annular rotor with each other, and necessary holders , which is disturbing for a fluid flowing in the rotors would be and reduced the efficiency of a turbomachine.
- the turbomachine is therefore preferably free of a component which extends along the axis of rotation of the rotors therethrough.
- the absence of a central shaft also has the advantage that in the channel entering foreign bodies, such as cords or nets, can cause no major damage.
- the drive mechanism is preferably also formed annular.
- the first drive wheel and the machine shaft need not necessarily be two separate components, but both may also form a single component, i. the first drive wheel can also be integrated into the machine shaft.
- the second and third drive wheel and the respectively associated rotor need not necessarily be two separate components, but both may also form a single component, i. the first drive wheel can also be integrated into the machine shaft.
- a particularly space-saving torque transmission relative to the circumference is thereby possible in that the first drive wheel, the second drive wheels and the third drive wheel each have a bevel gear provided with a toothing are formed, wherein the second drive wheels each form a bevel gear with both the first drive wheel and the third drive wheel, and wherein the axes of rotation of the drive shafts of the second drive wheels are at a right angle to the axes of rotation of the first and third drive wheel.
- the first drive wheel is provided with an internal teeth provided with cylindrical drive wheel and the second drive wheels and the third drive wheel respectively as cylindrical, provided with external teeth drive wheels, wherein the second drive wheels with the first drive wheel and the third drive wheel form a planetary gear and wherein the axes of rotation of the drive shafts of the second drive wheels are parallel to the axes of rotation of the first and third drive wheels.
- the third drive wheel may be a cylindrical drive wheel provided with inner teeth
- the second drive wheels and the first drive wheel may each be formed as cylindrical drive wheels provided with outer teeth, the second drive wheels forming a planetary gear with the first drive wheel and with the third drive wheel and wherein the axes of rotation of the drive shafts of the second drive wheels are parallel to the axes of rotation of the first drive wheel and the third drive wheel.
- the drive mechanism is preferably integrated in the housing.
- rotors are arranged one behind the other in the flow direction of the fluid, wherein in each case rotors arranged one behind the other are each coupled to each other via a drive mechanism described above in such a way that they rotate in opposite directions, ie, they contrarotate.

But it is also possible that the electrical machine is arranged annularly around only one of the rotors or around both rotors.
- the inner diameter of the annular rotor of the electric machine is greater than or equal to the inner diameter of the annular rotors of the turbomachine.
