Description

The utility model relates to the field of engineering, and can be used as an engine, pump, compressor.

The prior art synchronous two-rotor piston engine (Patent for invention RU No. 2056511, published March 20, 1996, IPC: F02B 53/00). The engine consists of two identical units placed in one housing symmetrically to its center of mass, the thermodynamic processes in which proceed synchronously. The block contains a housing, two cylindrical rotor pistons with rigidly connected flaps, a central cylindrical hinge with a groove, two peripheral hinges with grooves in which the flaps are pivotally connected to the rotors, two eccentric shafts with balancers and an intermediate shaft on which matching gears are mounted external gearing. Symmetrically to the central hinge, two identical cylindrical cavities in the form of cylinders are placed in the housing, in which rotors and pistons are run in with sliders, the flaps of which enter the groove of the central hinge, two combustion chambers, two peripheral hinge sockets and two mixing chambers. The central hinge is provided with channels through which the combustion chambers timely communicate with the boost-compression and expansion-exhaust chambers separated by shutters, and the shutters pivotally connected to the rotors are equipped with channels that regulate the flow of the mixture from the mixing chambers to the boost-compression chambers. Each combustion chamber in the process of compressing the combustible mixture communicates with the boost-compression chamber of one cylinder, and in the process of gas expansion, with the expansion-exhaust chamber of the other cylinder. When the shafts rotate, the piston rotors together with their shutters divide the body cavities into variable volume compartments in which thermodynamic processes occur that ensure the operation of the engine.

The disadvantages of this device include the complexity of the design, large energy losses due to friction in the guide pistons.

Known two-rotor internal combustion engine (Patent for invention RU No. 2129215, published on 04/20/1999, IPC: F02B 53/00). A two-rotor internal combustion engine consists of a block of two eccentric rotors, a common separation plate with "wrap-around" shoe shoes, and a piston block connected to the separation plate. New in the engine device is the implementation of the separation plate in the form of a block of pistons, the cylinder cavities of which communicate with the cavities of the rotor block through openings that are compatible when the combustible mixture is ignited and transferred to the cavity of the rotor block, and that the piston cylinders are double-sided.

The disadvantages of this device include significant energy losses due to friction on the working surfaces of the shoes, the guiding pistons.

Closest to the claimed technical solution is a two-rotor engine (Patent for invention RU No. 2136891, published September 10, 1999, IPC: F01C 1/00). The engine comprises a working rotor on which the working blade is mounted, and an insulating rotor separating the combustion chamber from the exhaust opening, having a cavity in which the blade enters during rotation, combined in one housing. The insulating rotor is driven into rotation by synchronizing gears included in the gear mesh, mounted on the rotor shafts outside the housing. The reduction of the compression work of the air entering the combustion chamber is carried out by creating a vacuum between the blade and the insulating rotor when the working blade leaves the cavity of the insulating rotor. The working blade is located in the combustion chamber.

The disadvantages of this device include the complexity of the design, not enough high specific power, high requirements for balancing the rotors, caused by the geometry of their shapes, unusual for bodies of revolution.

The technical result of the proposed utility model is to simplify the design, expand functionality, reduce axial load, ensure smooth rotation of the rotors, two-rotor machine.

The technical result is achieved by the fact that the two-rotor machine comprises a housing, an inlet channel, shafts with synchronizing gears mounted on them, an exhaust channel. Moreover, the working chamber is formed by a housing and two identical rotors installed symmetrically inside the housing with minimal gaps between them on parallel shafts pivotally mounted in the housing with the possibility of free synchronous rotation in opposite directions. Moreover, each of the rotors is made in the form of a disk with cutouts and is rigidly fixed to the shaft with the possibility of alternating passage of their blades through the working area of the housing. The housing is equipped with a second exhaust channel. Moreover, the exhaust channels are located on opposite sides of the housing, symmetrically with respect to the axis of the inlet channel.

Moreover, each of the rotors, made in the form of a disk with cutouts, forms blades, for example, in the form of a Maltese cross.

The essence of the utility model is illustrated by figures 1-2, where

Figure 1 - General view of a two-rotor machine;

Figure 2 is a front view of a two-rotor machine (in section).

The two-rotor machine (Fig.1-Fig.2) contains a housing 1, on the end surfaces of which are mounted and oval shaped caps 2, an inlet channel 3, two shafts 4, 5 with rotors 6, 7, synchronizing gears 8, two exhaust channels 9, 10.

An energy source (not shown in the figures) is located outside the body of the two-rotor machine. The intake of the working fluid, for example, from an autonomous combustion chamber, into the housing 1 is carried out through the inlet channel 3.

Two shafts 4, 5 are mounted inside the housing parallel to each other and pivotally mounted on shafts 4, 5; two identical rotors 6, 7 are installed symmetrically, with minimal gaps between them, each of which is made in the form of a disk with cutouts forming the blades for example, in the shape of a Maltese cross. On the shafts 4, 5 on the outer side of the covers 2 of the housing 1, synchronizing gears 8 are installed, which ensure the synchronization of the angular velocities of the elements of the mechanism of the two-rotor machine.

In this case, the rotors 6, 7 are mounted and rigidly fixed on the shafts 4, 5 symmetrically relative to each other with a minimum distance between them, with the possibility of alternating passage of their blades through the working area of the housing 1. Moreover, the distance between the shafts 4, 5 is determined by the possibility of free synchronous rotation of the rotors 6, 7 in opposite directions. In this case, the working chamber is formed by a housing and two identical rotors mounted on parallel shafts, pivotally mounted on the end caps inside the housing, with the possibility of free synchronous rotation in opposite directions.

The output of the working fluid (steam, gas) from the housing 1 is carried out by means of two exhaust channels 9, 10 located on opposite sides of the housing 1, symmetrically with respect to the axis of the inlet channel 3.

The work of a two-rotor machine is as follows. The working fluid (steam, gas) under pressure comes from an autonomous energy source (for example, a combustion chamber) to the working area of the casing 1 of the two-rotor machine through the inlet 3. The pressure force of the working fluid entering the working area of the casing 1 alternately affects the rotor blades 6 , 7 mounted on shafts 4, 5 mounted on parallel mounted and pivotally mounted inside the housing 1 bodies. Rotors 6, 7 are mounted on the shafts 4, 5 with the possibility of alternating passage of their blades through the working area of the housing 1 and rotate in opposite directions under the deis Tweed working fluid. Between the blades of the rotors 6, 7 and the inner surface of the housing 1 in the working area, a minimum clearance is provided that excludes friction of the blades on the walls of the housing 1. Moreover, the rotors 6, 7 are located in the annular channels of the housing 1. The difference between the pressure on the blades entering the zone of the annular channel and the blades engaged in the rotors, due to their mutual overlap, causes the rotors to rotate in opposite directions. A large radial arm allows you to get a huge torque on the output shaft even with a low incoming pressure of gas or steam from the energy source into the housing 1.

The pressure of the working fluid allows you to get a huge torque and a large specific power and efficiency on the shaft of a two-rotor engine, as well as provide instant start-up at low temperatures. The two-rotor machine is easy to manufacture, as it allows the use of rotors in the form of disks with cutouts forming blades, for example, in the shape of a Maltese cross. The proposed shape of the rotors allows for a smooth running of the rotors, a high degree of reliability and protection against overload on the shaft.

There are no intertwining parts in the design of a two-rotor machine, except for the shaft support (rolling bearings). No need for lubrication, liquid cooling system, gearbox, since the two-rotor machine itself is a gas-dynamic gearbox providing speeds, the required amount of torque on the shaft and shaft speed.

Tests of the manufactured prototype confirm that, with the simplicity of the design, the proposed two-rotor machine is reliable in use, allows for smooth running of the rotors, provides high power and environmental friendliness. Its specific power is 60-90 G per horsepower. The design of the two-rotor machine allows reversing and large overloads, has the property of reversibility. A two-rotor machine can be used as an engine, compressor or pump.
