The invention relates to devices for converting rotary motion into reciprocating and on this basis, devices, movers, moving, both in stationary conditions on the solid surface and non-stationary, underwater, surface and air environments and outer space.

The method of converting rotary motion into reciprocating widely used in various mechanisms, for example, it is well known that in a lathe caliper moves progressively from the helical rotation of the shaft /1/ crank-rocker mechanism rotating from the engine with a drive crank passes the wings of the reciprocating movement. Known methods for converting rotary motion into reciprocating share a common drawback, since it is mainly used in stationary conditions, in non-stationary conditions, their application is limited /2/.

There are also devices /3/ in which the rotor rotates is attached to the cargo on the curve other than a circle, such as elliptical, and the eccentricity of the axis of rotation causes the inequality of the centrifugal forces acting on the axis of rotation, and when the device is in a free state relative to the plane of rotation of the rotor with cargo, the resulting differential force causes translational movement of the disorder in the direction of greater radius from the center of rotation, French patent No. 2.059.822.

The known device, Fig.1, is a device for converting rotary motion into reciprocating. The operation of the device, according to the description, as follows. There is a circular rotor 7 is driven in rotary motion through the shaft 6 of the electric motor. Around the circumference of the rotor 7 are located on the rods 2 goods I, which in the radial direction in the guides 13 have free course and during the rotation of the rotor shaft (shaft) 6 loads I due centering forces diverge (ejected) from the rotor 7. The rotor 7 is placed in a cylindrical diamagnetic eccentric ring 3. To avoid friction loads I on the inner wall of the cylinder 3 suspension rotor loads in the cylinder 3 is implemented using a system of electromagnets, of which 9 are located on the body portion 10 on the rotor, and the interaction of the electromagnetic fields of the rotor and the housing, which are directed oppositely. Suspension rotor carried out so that does not allow the goods I touch the walls of the cylinder, that is the case. When you spin the rotor around the axis (axle) 6 centrifugal forces push the goods I from the rails 13. Due to the eccentricity of the cylindrical rings of the rotation axis (imaginary) 6 does not coincide with the axis 6 of rotation of the rotor 7. The rotation of the cargo I is on a trajectory that is different from the circumference. In this the is trojstva this trajectory ellipse, or close to it on the form. For this reason, thrust 2, on which is mounted cargo I at diametrically opposite ends of the major axis of the ellipse are different lengths, while rotating continuously forward and slide in the direction of the eccentricity, there are different centrifugal forces of inertia on diametrically opposite parts of the rotor. Their differential force directed from the rotation axis 6 toward the center of the cylindrical ring 5, when the rotation is permanent, and moves the entire device together with the motor in a given direction in the plane of rotation as the cylinder 3 and 5 can be rotated around the axis 6. Known Electromechanical device and therefore has a mechanical interaction of parts (elements) with each other, for example, the raising of goods I on the rails 13, and the reverse in motion by means of the electromagnets 10, which requires a constant current source, the rotation of the rotor 7 of the shaft 6 is effected by an electric motor, it also requires a source of electricity. The working scheme bulky in addition, the efficiency of such devices cannot be large due to friction losses in the nomination and the moves of goods I, and eventually this Converter as a mover for non-stationary conditions is practically not applicable.

As a prototype of the device of the invention selected device down Pat is the DE 19909766 A1. The device, Fig.2, 3 represents the mechanism that possesses characteristics of both planetary and differential gear. Gear is installed on the Board I, which is included in the actuator 12, on the Board I also installed the motor 10, through which the drive II activates the device. The eccentric drive mechanism consists of 3 toothed gears, interconnected in a certain way.

With the motor 10 through drive II the rotational energy is transmitted to the main gear wheel 4, which is reinforced through the bearing 3 on the axis 2. Axle 2 mounted on Board I, at some distance from the centre axis 4 of about23radius fortified axis 5, which is above through the bearing 6 fortified gear wheel 7. Above 4 wheel axle 2 fortified stationary gear wheel 8. The diameters of the wheels 7 and 8 are identical, identical to the number of teeth of the wheels. On the wheel 7, toward the rim, approximately the length of the radius from the center secures the load 9. Wheel 7 through the bearing 6 fortified (installed) on the axis 5. The moving device 12 operates according to the description, as follows. The wheel 7 can freely rotate around the wheel 8, making a full 2 turns 1 turn around the wheel 8 that during the initial installation of the wheel 7 with gr the zoom 9, as shown in Fig.2 and 3 shows, the arrow V indicates the direction of movement of the actuator 12. When turning on the motor 10 through the drive II begins to rotate the main gear 4, which by means of the axis 5 begins to rotate the wheel 7 with the load 9. Wheel 7 begins to turn stationary wheel 8, which causes the rotation of the wheel 7 with the load 9 around its axis and around the wheel 8, i.e. around the axis of the wheel 8, the movement of the load 9 is portable and is on the curve, indicated by the dotted line in Fig.3. From the graphical model of the movement of cargo 9, Fig.4, it is seen that during one revolution of the wheel 7 around the wheel 8 load 9 from point And successively moved into position AI...AII through 30° and back to A, because the load 9 simultaneously rotates around the center and center 0, radius of rotation of the weight around 0 is constantly changing from maximum to minimum OA OA6, and, consequently, the speed of rotation of the weight 9 at a constant speed of the motor II is proportional to the radius, with reference to Fig.4 speed cargo 9 at point A6 is equal to zero, and if the rotation radius OA counterclockwise, starting from the speed at point A6, it gradually increases, reaches a maximum point And then decreases to zero, the point A6. Combining smooth line (extrapair) points A,AI...AII,AI2, obtain a curve, which moves the load 9. The coordinates of the points can be defined mathematical expression is iceskates, depending on the rotation angle φ of the rotation axis OA with respect to axis X,X=dcosφ+d2φ,Y=dsinφ+d2sinφand , in Fig.4 shows an example of determining the coordinates of the point AI(X2, Y2),X2=dcos30+d2cos60,Y2=dsin30+d2sin60,d - wheel diameter(a) of 7.8. The movement of cargo 9, is on a curve, which in mathematics is known as a cardioid family of curves ”snail Pascal” /5/. As a result of movement along this curve is the rapid alternation (switching) of the speeds of fast forward motion, to slow in the opposite direction. To achieve stability of the drive transmission 12 proposed on a common drive I0 e/motor II to install identical drives 12', Fig.5, chap the main wheels which rotate in different directions. In Fig.5 shows a set of 3 identical drives 12' with an offset of 120° about the circumference of the actuator 10. However, this cannot exclude the main disadvantage of such devices is a sharp switching of the direction and speed of movement of the load 9 in gears restricts the use of high speeds, secondly, the movement of the actuators 12, 12' is possible only in the plane of rotation of the gears in the drive direction change requires shifting of cargo in stationary conditions, design the circuit using wires, batteries limits the range and makes the device bulky.

The aim of the invention is the creation on the basis of the method of converting rotary motion into reciprocating simple and reliable device, taking into account the elimination of the above disadvantages, suitable for the movement (movement) in non-stationary environments: underwater, surface, air environments and outer space with dealing with the gravitational forces. The invention of mechanical, converting rotational motion into translational and rotation of goods takes place along the curve, nalivaeva "snail Pascal", in honor of the French scientist étienne Pascal (1588-1651), which is a type of generalized conchoid Nicodemus (251-150, BC) /5/. Curve "snail Pascal" is the equation (x2+y2-ax)2=l2(x2+y2)(I)where x and y coordinate axes in the plane of the drawing, Fig.2, a diameter of a circle K, and segments RM=RM=l, l and a=const. In the drawing of Fig.2 by the formula (I) built 4 curves at different ratiosla. So, ifla2correspond to curves I and 2, inla2curves 3 and 4. When analyzing the curve 4(la=73), Fig.2, in the formula (I) take y=0, polychem ±X=±(l)+a, x=l+a-x=-l+α. In relation to the lines AO and OS, Fig.3, have AO+OC=(X)+(-X)=l+a+l-a-2l, which corresponds to the length of the AOC. When X=0, y=l, y=-l the length of the line FG=2l and AOC=FOG. Any line passing through the pole, the point 0, Fig.3, from opposite ends of the "snail Pascal" by the formula (I) and la2always equal to 2l, respectively, direct NPOM equal to 2l. In the formula (I) take x2+y2=R2where R is the radius of krivsky curve 4 relative to the pole 0, then the formula (I) can be written in the form (R2-ax)2=l2R2or R2-ax=lR andx=R2-lRahereR-axR=lbutxR=cosφwhere φ is the angle between the straight line Ω and the X-axis, then R-coφ=l, a-cosφ=OP, Fig.2, PM=l and NO-OP=l and NOPM=NOP+PM=2l. Depending on the angle of rotation only changes the ratio between the line segments, for example,NOOMand when X=0 will take the place of the FG, that is,FOOG=1and FO=OG=l. From this it follows that if we rotate the line AOC=2l around the pole About, the relationship of the lengths of line segments AB and OS during rotation of the post is constantly changing and in 12turnover segment AO is shortened on a and takes the place of the OS, and the OS segment through12turnover is extended for a and for one revolution of the line speakers, this happens twice. This conclusion is based invention device Converter rotary motion into reciprocating. The ratio ofla2is selected from the following: effective conversion reached a maximum radii ratio: more AO to a smaller OS or Vice versa, the minimum ratio of the smaller radius of the OS to a large AO. Ifla=2according to (I)OAOC=3ifla2the ratio ofOAOC=3curve 4, Fig.2, built by l:a=7:3 and OAOC=2,5. Ifla2the curve takes the form 3, on the X-axis is formed by the inflection point C3 and the "saddle" gives the curve of the oval shape, which does not allow to obtain an effective Converter. If l:a=1 curve 2 is also unsuitable for conversion. In Fig.3 by the formula (I) is a curve in l:a=2:1 1:1 scale in centimeters: 2l=10 cm, l=5 cm, a=2,5, see the Device, inverter rotary motion into reciprocating, contains a mechanism that utilizes a structural model based on theoretical curve 4 "snail Pascal" Fig.2, and consists of 2 main parts, Fig.6, the wheel 1 and the rod 2. The wheel 1 has an eccentric shape, defined above, the rod 2 through the slit is installed on the axis, rotational movement causes simultaneously and progressively along the slit. Wheel 1, Fig.7a, has a holding and guiding groove (Golob) 2 for rotating thereon rollers 3 of the rod 1. K the rollers 3 are mounted cargo 4, but the role of cargo 4 can perform the rollers 3. Rim (wheel) 1, Fig.5, has a dense (blank) landing on the axis 5, one end of which, the right according to Fig.5, is attached to the housing of the device, and the other is in the bearing Cup 5 forces the first shaft (axis) 6, so that is not prepyatstvuet free rotation of the shaft 6. Axis 5 passing through the wheel 1 in the calculated pole 0. The rod 1 is rigid symmetrical design, in both directions from the center rod has a longitudinal through crack of length l, the length of the rod must ensure that the installation of the rollers 3 in the guide groove 2. The Converter operates as follows: to the axis 5 is supplied torque from any type (species) of the engine, internal combustion, electricity, steam and others. The motor rotates the shaft 6 at the end of the shaft there is a special plug, Fig.6, which covers the rod (s), Fig.7, with goods and rotate them on the wheel rim. For one revolution of the rod loads double-pass upper and lower part of the wheel rim, and because goods at the same time on opposite ends of the rod, at large and at small radii, the resulting centrifugal force equal to the difference of the radii and in the optimal case, as has been proven, inla=21the force vector acting on a large radius, 3 times more than in a small radius. The Converter with the engine mounted on a common chassis, forming the propulsion and control device is moving. The Converter can be used is the s at an angle of 90° with respect to each other 2 rods, Fig.8b, respectively, the device torque rod, forks, Fig.8A, is complicated. A subsequent increase in the number of rods due to technical opportunities, the number of rods are more than one places a load on the engine, more uniform during the transformation. The block diagram of the device movement is shown in Fig.10, where 1 - engine, 2 - a Converter, 3 - governance. Analog devices move (movement) on a solid surface adopted the well-known domestic bike with a frame on which strengthened wheel, pedal to the driving chain wheel (a), the wheel control. The proposed device, Fig.11, contains some of the elements of the bike: frame (housing) 1, wheel 2, pedal 3, a chain transfer 10 on the axis 4. Unlike bike axle 4 causes the rotation of the rod 5 of the Converter. Mounted on the rod 5 cargo 6 rotate in the guide grooves on the rim curve "snail Pascal" 7. As the engine is the muscular force of the person, which is placed on the support seat with backrest (shown in Fig.11 by the dashed line). The control device is a rotation in the vertical plane "wheels Pascal" (similar curve "snail Pascal") rudders turn 8, with respect to the frame 1. Turning the wheel in the vertical plane, changes the direction of the action of large and small radii and, respectively, the resulting vector is Il, Fig.8, 9. The control device allows it to move over a solid surface of the Earth, to rise vertically upwards, overcoming the force of gravity, move in air and vacuum. The control device also allows you to choose an intermediate movement type, for example of the weight of the device moves over a solid surface, some of the weight takes the vertical component, because the total force vector, Fig.8, there is a horizontal and vertical components. In Fig.8 in the plane of the drawing shows in vertical plane forces acting on the device in a tilt of the wheel from the vertical. The forces indicated in Fig.8 (9): F - summry vector from the rotation of the cargo; Fg- power pritjagenia; Fn- the horizontal component of the vector F; Fin- the vertical component of the vector F and vector Fg. The device, Fig.11, fixed on the boat, allows movement through the water. Control in the horizontal plane, according to the authors, does not pose serious problems.

FIELD: transport.

SUBSTANCE: invention relates to surface transport facilities. Motion and reverse braking of wavelet are driven by system composed of two interacting bodies, that is, wavelet with the set of primary elements of pulse transformers and secondary elements of pulse transformers. Every of the latter in primary element can reciprocate along its primary element in one side and in reverse direction at reverse speed. The latter is lower than its working speed that creates the difference between working and reverse pulses of secondary element. Set of pulse transformers consists of primary and secondary elements built around free-piston ICE. Every primary element is composed of cylinder with exhaust and vent openings at its centre. Starting openings are arranged at cylinder edges, heads and atomizer with holes are secured to cylinder edges. Every secondary element in pulse transformer unit is a free piston.

EFFECT: creation of pulse transformer unit.
