Description

A useful model relates to the field of instrumentation and nanotechnology.

There is a known method of moving an object in space (Application for invention No. 95116610, IPC F03G 3/00, filing date of September 26, 1995), in which, by means of a vibration exciter of an inertial propulsion device, it transforms the work of an energy source into work ensuring the movement of an object by performing antiphase promotion the inertial mass of the vibration exciter relative to at least two rotation axes to a technologically specified angular rotation speed with subsequent change in one section of the trajectory of the angular momentum relative to with respect to the corresponding rotation axes of at least two inertial masses that are specularly symmetrically located relative to the plane of symmetry of the vibration exciter, with the possibility of converting at least part of the kinetic energy of the inertial masses into a pulsed directed force on the rotation axis and subsequent stabilization of the corresponding dynamic parameters of the inertial mass rotation relatively technologically given rolling parameters of rotation, so that for the implementation of the conversion process For the operation of the energy source in the work that ensures the movement of the object, a vibration exciter is used with inertial masses pairwise connected and diametrically opposed in relation to the respective rotation axes in each pair, the angular momentum of at least two inertial masses is changed by their accelerated radial movement with change values of their radii of rotation in a cycle from the initial maximum value of the radius of rotation to the minimum value specified radius and vice versa, within a rotation angle not exceeding 180 ° and with the possibility of providing only a unidirectional pulsed force action on the corresponding rotation axis within a rotation angle equal to 360%, stabilization of dynamic rotation parameters is carried out with respect to the angular velocity of inertial masses from the moment the beginning of the increase in the radii of rotation of the corresponding at least two inertial masses from the minimum specified value of the values of these radii to the initial maximum value radii of rotation. The disadvantages of this invention include the fact that the conversion of kinetic energy into force disturbance does not occur in full; there is a high complexity of stabilizing dynamic parameters.

Known engine design (Application for invention No. 92015533, IPC В02С 12/38, filing date 12/30/1992 g), the technical solution of which is to simplify the design of the engine. This goal is achieved by performing a drive in the form of a wave transmission with a piezoelectric wave generator that contains a circular row of radial pushers mounted in a common housing with linear piezoelectric drives with multipliers of current masses located between the pushers and piezoelectric power elements, as well as a flexible wheel mounted on the shaft of the object engine application and placed in the annular gap between the housing and the pin inserted into it - the central hard wheel of the wave transmission . The current mass can be made of electrorheological liquid or a liquid magnet placed in the radial sockets of the housing together with electromagnetic coils (instead of piezoelectric elements), or as drive elements in the radial sockets can be installed (instead of piezoelectric elements and fluid mass), alternately heated and cooled by liquid or air rods or tubes made of polyethylene or other material with a high coefficient of thermal expansion. In addition, the drive can be made in the form of a spiral - a spiral spring, one end sealed in the housing, and the other - connected to the rim of the freewheel coupling mounted on the shaft of the engine application object, and equipped with two hair dryers for alternately blowing the spring with hot and cold air (for blowing with cold air the heater of one hair dryer is turned off). The specified spiral can be made bimetallic current-carrying, or in the form of a differential wall-carrying tube, as well as from a material having a high coefficient of thermal expansion. The disadvantage of this invention is that the piezoelectric elements have a rather fragile structure and do not tolerate impacts, they are characterized by fragility and their parameters float in time. They also require stabilization of the temperature of heat dissipation.

The closest analogue is the design and principle of moving an object in space. The so-called "piezoelectric motor with protruding gaskets" (S.A Sdobnikov, A.A.Vosilyakov, I.V. Rubtsov "Piezoelectric motors on a traveling wave: principles of operation and design features" // Mechatronics, automation, control. No. 6. - 2002 . 43-45.). The engine consists of an external cylindrical rotor, inside of which there is an annular cylindrical stator element of piezoelectric material, mounted along the inner generatrix on the flange.

On the outer cylindrical surface of the stator piezoelectric element, elastic steel pusher plates are fixed, which are installed at a certain angle to the inner surface of the rotor and are in mechanical contact with some pressure. Pusher plates are made of steel and elastic. Thanks to the plates acting as intermediate elastic elements, the rigidity of which is much less than the rigidity of the piezoelectric element.

When applying a control voltage of alternating current to the electroded sections of the stator piezoelectric element located on its outer and inner cylindrical surfaces, the outer cylindrical surface of the stator piezoelectric element begins to oscillate in the radial direction with the frequency of the control voltage. Moreover, in each pusher, along its length, there is a standing mechanical wave, forming an elliptical trajectory of the end of the pusher adjacent to the stator.

The movement of the end of the pusher is converted into rotational motion of the rotor due to the forces of frictional interaction.

The disadvantages of this invention: the change in the linear dimensions of the piezoelectric elements is insignificant, while they cannot realize a large force on the rotor, and are also characterized by low durability and lose their properties in a short period of time.

The objective of the utility model is to increase the reliability of the inertial wave engine.

The problem is solved in that the inertial wave motor design includes a stator, rotor and actuator. The stator is made in the form of a part of the pipe with a corrugated inner surface, a rotor is placed inside the stator, masses are located between them, for example, in the form of rollers, as well as actuators, all rollers are interconnected by springs, including actuators, each mass being rigidly supported associated with the mass, a thrust element, which at one end is connected to the mass abuts against the internal corrugated surface of the stator, with a pusher fixed at one end to the roller, the other end comes into contact with the surface p Operations and the frictional forces ensures rotation of the rotor. Moreover, there may be several actuators depending on the given speed of movement and the moment developed on the stator. Each actuator is supplied with energy.

Actuator - a subsystem that transfers the effect from the control device to the control object. In the proposed utility model, actuators can be used - converters that convert the input signal (electrical, optical, mechanical, pneumatic and any other) into the output signal (into motion), which affects the control object (masses located on both sides of the actuator). A device of this type may include: electric motors, electric, pneumatic or hydraulic drives, relay devices, electrostatic motors, etc.

In the proposed utility model, the actuator is designed to create displacement at certain intervals of time, which ensures constant operation of the inertial wave motor.

The essence of the invention is illustrated by drawings.

Figure 1 presents a General diagram of an inertial wave engine.

Figure 2 presents a diagram of the transmission of forces to the rotor and stator.

Figure 1 shows: stator 1, rotor 2, masses 3-10, actuators 11 and 12, springs 13-20, rigid couplings of masses 21-28, thrust elements 29-36, pushers 37-44.

Figure 2 shows a diagram of the forces, including:

- the force initiated by the actuator 11;

- the force transmitted by the thrust element 29;

- the force ensuring the equilibrium of mass 3 through rigid bonds 21;

- the force transmitted by the pusher 37;

- force initiated by the spring 14.

The inertial wave engine consists of their stator 1 in the form of a part of a pipe with a corrugated inner surface; rotor 2 located inside the stator 1. Between the stator 1 and the rotor 2 placed mass 3-10, which can have different mass and shape, and are evenly distributed around the entire circumference. They can be made in the form of rollers. Actuators 1 and 2 are located between the masses. Their number is set depending on the weight of the masses and the forces that must be created to rotate the rotor 2. All masses 3-10 are connected by springs 13-20, as shown in FIG. The masses 3-10 are equipped with rigid links 21-28, which provide the balance of the masses when they rotate between the stator 1 and the rotor. The masses also have thrust elements 29-36, which are pivotally connected at one end to the corresponding mass, the other end slides along the corrugated surface of the stator when moving clockwise, and counterclockwise rotates against the corrugated surface of stator 1 and provides an emphasis. Pushers 37-44 provide the transfer of forces to the rotor 2, they are fixed at one end to the mass, and the other enters into close contact with the outer surface of the rotor.

Actuators 11 and 12 have an energy supply and can pull the nearest mass (located clockwise) during operation and are designed to create an initial bias, which allows you to create a traveling wave, pulses from the actuators come through each period of the wave (the wave propagation period refers to the propagation of the bias from the actuator 11 to the actuator 12 and vice versa). The pulling up of the mass occurs due to the fact that the spring located behind the actuator, after moving the latter, becomes stretched and, due to elastic forces, strive to take its original position, which in turn leads to pulling up of the nearest mass. Thus, the actuator provides a constant energy supply to the traveling wave.

The inertial wave engine operates as follows.

Consider the operation of the engine in a separate area. Energy is supplied to the actuator 11, the actuator pulls the mass 10, together with the mass, the stop element 36 moves, the spring 13 is compressed. Then it begins to expand and pushes the mass 3, and moves it together with the thrust element 29, respectively, the force is transmitted to the pusher 37 and the rotor 2 moves a certain distance. Spring 14 transfers force to mass 4.

Actuator 12 acts in a similar way, providing the movement of masses, and, consequently, the rotation of the rotor 2. The principle of energy transfer in a closed circuit of a mechanical circuit is provided.

The calculations showed the efficiency of the proposed utility model.
