DEVICE FOR TRANSMITTING MOVEMENT TO MOVEMENTS

The field of technology

In the field of mechanical engineering, the invention belongs to the field of machine elements and units, more specifically to mechanisms, and quite specifically to the field of mechanisms for changing the rotary to linear alternating motion.

In the international patent classification, the subject matter of the invention is therefore classified in class F 16 H 25/08.

A technical problem

Starting from a device for converting rotary to linear alternating motion, the invention is based on the problem of how to modify the object structure in order to eliminate any physical connection between rotating and linear alternating moving parts.

The state of the art

Devices for converting rotary to rectilinear alternating motion are generally known. These include either eccentrics, crank links or similar mechanisms, all of which have a common physical interconnection between the rotating and the linearly rotating element. As a result, friction occurs in the joints, hinges, joints and all points of interconnection, resulting in a drop in efficiency. Particularly for mechanisms comprising crankshafts, pistons and cranks

21329PR0.IV hinges, relatively large forces occur during operation as a result of translational and rotational masses, which load the bearings and hinges while also causing unwanted vibrations. A disadvantage of the known solutions is also the relatively high mass of such devices, which is formed by the masses of various mechanisms.

Description of a solution to a technical problem with an example implementation

The technical problem according to the invention is solved by the fact that the device for changing the rotary to linear alternating motion comprises in a double tightly closed elongated cylinder, a hole in which a pneumatic valve is screwed in, transversely mounted on the cylinder with a transverse valve in which the screw valve is screwed in. and a bilaterally operated piston slidably arranged in paramagnetic material along the longitudinal direction. The latter is substantially halfway along its longitudinal dimension with an elongated axis, with respect to its transverse symmetrical axis, a symmetrical cutout, the extreme ends of which are opposite to the adjacent ends when viewed in the longitudinal direction of the cylinder. In this case, a cylindrical cylindrical arrangement is arranged in at least one front surface of the piston. The cylinder is essentially, in its transverse symmetrical axis, designed with a pair of diametrically opposite holes through which the bearings are arranged. In the latter, a drive shaft is mounted on which a centrally fixed rotor is located in the area of the piston cutout, which is located at a constant distance from the longitudinal wall of the cutout.

The piston, in the area of its respective opposite ends, is formed by radially extending grooves, in which the seal is fitted to the cylinder in each case. In the cylinder spaces formed by the wall of the latter, the respective piston face and each cover are arranged, as a spring, by acting compressed gas cushions, in the case of air.

The rotor further comprises a pair of equidistant, spaced apart and essentially truncated cones of nonmagnetic material designed by the hubs arranged on the shaft mirrored relative to the longitudinal axis of the cylinder. In this case, the base surfaces of the tapered hubs face each other, while the tapered ends rest on the bearings. Between the base fists and in the area

21329PR0.IV Their radially largest dimensions are a rotor ring centrally fixed with a shaft, a rotor ring, consisting of a ferromagnetic material, designed with a ferromagnetic material.

I further concretise the invention on the basis of the embodiment shown in the accompanying plan, in which FIG. 1 is a longitudinal sectional view of the device according to the invention; 2 is a cross-sectional view of the device according to the invention in line II-II of FIG. 1, FIG. 3 is a longitudinal cross-section of the device according to the invention in line III-III of FIG. 1.

The device for converting rotary to rectilinear motion according to the invention comprises an elongated cylinder l, which is formed on its front surfaces by flanges 2, 3. In each flange 2, 3, a longitudinally extending groove 4 is formed on its front side and concentrically with the cylinder 1, 5, into which gasket 6, 7 is inserted. The cylinder 1 is tightly closed from its respective front side by covers 8, 9 adapted to flanges 2, 3, wherein the second cover 9 is formed by a centrally through hole 10. The wall of the latter it is designed with a concentric groove 11 extending in the radial direction of the cover 9, wherein a seal 12 is arranged in the groove 11. The covers 8, 9 are connected in a known manner to the non-shown screws in a known manner.

Cylinder 1 is basically halfway along its longitudinal dimension, i.e. in their transverse symmetrical axis, formed by a pair diametrically opposite the through holes 13, 14, in which the roller bearings 15, 16 are arranged as appropriate, and which are held on the outside of the cylinder 1 by the bearing caps 17, 18. the cylinder 1 is fixed by the unscrewed screws, and are each designed centrally through the holes 19, 20. In the area of the joint with the respective flange 2, 3, the cylinder 1 is designed with one through hole 21, 22 connecting the interior of the cylinder 1 to the surroundings, and in which the pneumatic valves 23, 24 are screwed on.

In the cylinder 1, a double-acting piston 25 of paramagnetic material is slidably disposed in a loose fit and in a longitudinal direction. It is substantially halfway along its longitudinal dimension with an elongated, relative to the transverse symmetrical axis of the piston 25, a symmetrical notch 26, the extreme opposite ends of which are 27, 28, seen in the longitudinal direction of the cylinder 1 or. pistons 25 are designed in a semicircular manner with a diameter equal to the transverse dimension in the given

21329PR0.IV In the case of width, notch 25. In the area of each opposite end, the piston 25 is designed with a radially extending groove 29, 30 in which a sealing ring 31, 32 is arranged to the cylinder 1, at that end of the piston 25, facing of the cover 9, which is designed with a through hole 10, a cylindrical nozzle 33 extending through said hole 10 centrally with the piston 25, in close alignment with the seal 11. The piston may, of course, be designed with a further cylindrical extension similar to the extension 33 , also at the opposite end, in which case the cover 8 must also be designed with a corresponding through hole similar to hole 10.

In the spaces of cylinder 1 formed by the wall of cylinder 1, the respective face of the piston 25 and the respective cover 8, 9 are arranged as spring-acting pads 34, 35 of the compressed gas, optionally air supplied and discharged via valves 23 , 24 and bores 21, 22.

The device according to the invention further comprises a drive shaft 36 extending into the cylinder 1 and through the recess 26 of the piston 25, being housed in rolling bearings 15, 16. Away from the bearing cover 18, the projecting shaft 36 is designed with a flange attachment 37 which can be mounts any rotary drive motor via the intermediate clutch (both not shown in Fig.). On the shaft 36 is further centrally arranged rotor 38, located in the area of the cutout 26, and comprising a pair of identical, spaced apart from each other and essentially as a truncated cone designed hubs 39, 40 made of non-magnetic material arranged on the shaft 36 in mirror with respect to the longitudinal axis cylinder 1 and in a known but not shown way secured against rotation. The base surfaces of the tapered hubs 39, 40 face each other, while the tapered ends face the bearings 15, 16, which they also support. Between the base surfaces of the hubs 39, 40, in the area of their radially larger dimensions, the rotor ring 41 is made centrally centered by a shaft 36 of a nonmagnetic material, the latter being designed with an excitation section 42 of ferromagnetic material. In this case, the maximum radial dimension of the rotor 38, and thus the hub 39, 40 as well as the rotor ring 41, is in each case smaller than the width of the elongated through hole 26 of the piston 25, so that in no case does contact occur between the cutout wall 26 and the rotor 38 The diameters of the ends 27, 28 of the cutout 26 are similar to the diameter of the rotor 38; they are essentially equal to the width of the cutout 26.

21329PR0.IV

The piston 25 is secured against the rotation about its longitudinal axis by a pair diametrically opposite the sliding guides 43, 44 arranged in the circumference of the piston 25 and extending longitudinally through the piston 25 and attached to the respective cover 8, 9. Further, piston 25 which, for ease of installation, is designed from two equal halves - substantially divided in the plane of its transverse symmetrical axis - again by a pair of clamping screws 45, 46 arranged substantially between the guides 43, 44 when viewed in the direction of the circumference of the piston 25.

The device for converting rotary to linear alternating motion according to the invention works as follows.

In this case, the piston 25 is rested idle on the airbag 35. When the rotor 38 is rotated on the shaft 36 by means of a non-driven drive motor, which may be either an electric motor, an internal combustion engine, a water turbine, a wind turbine, or the like, at some point the excitation section 42 approximates to the first longitudinal wall of the cutout 26 of the piston 25 to the maximum extent possible, and then the maximum possible magnetic force is applied to the piston 25. It pulls the piston 25 in the direction of motion of the excitation section 42, thereby further compressing one of the spring-acting pads, e.g. a cushion 35, in which pressure increases, which pushes the piston 25 in the opposite direction. When the rotor is rotated for further runs, the excitation section 42 approaches the second longitudinal wall of cutout 26 of piston 25 as far as possible, which is now drawn in the opposite direction by magnetic force. This movement of the piston 25 is also aided by the pressure of the cushion 35 acting on the front face of the piston 25. This causes the piston 25 to move upwards, now increasing the pressure in the second air cushion 34 and now pushing the piston 25 in the opposite direction.

Over time, the constant speed rotor 38 drives the piston 25 into oscillation in the longitudinal direction of the cylinder 1, with the oscillation frequency of the piston 25 being substantially equal to the rotation frequency of the rotor 38, which in itself can be controlled in a known manner. However, due to the constant pressure of the airbags 34, 35, they are heated, which further increases the pressure of the said airbags, thereby changing the characteristic essentially of a spring of the functioning airbags 34, 35; the characteristic becomes stiffer, which makes it able to react more quickly to the displacement of the piston 25, essentially with the rotor speed 38.

21329PR0.IV

The device according to the invention can be used in all areas where it is necessary to change the rotation in a linear alternating motion. It is preferably provided for the transmission of energy through the Earth's crust. This is achieved by the fact that the nozzle 33 of a piston 25 with a constant frequency, preferably between 1 and 200 Hz, strikes a non-displayed pillar arranged in the earth's crust and extending from the surface of the earth's crust at right angles to a certain depth. The pillar oscillates at a forced frequency equal to the frequency of motion of the piston 25, emitting mechanical waves of the same frequency into the earth's crust. At some other place in the earth's crust is a well-known receiver of these waves, which then transforms them first into mechanical oscillation, and then into e.g. electricity.
