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 about
