The invention relates to the field of engineering, to methods and structures of the conversion or transfer of motion, and also to obtain the necessary movements in various hydraulic devices, pneumatic motors, internal combustion engines (ice), pumps, flow meters of different types: with swinging blades, pistons, etc., in h the belt ratio [1], involving the use of non-circular gears.

A known mechanism design with variable gear ratio [1], which contains two non-circular bevel gears, interacting with each other.

The disadvantage of this effect and structures is the application complicated to manufacture gears.

Prototype

It is known device for converting motion [2], containing the compound at least two phone

Criticism prototype

A disadvantage of the known construction is that the top gear ratio is changed stepwise, and the manufacturing sector of the wheels, compared to conventional round wheels, is more time consuming. The disadvantage is that you cannot use wheels of this form in the chain, belt or other gear.

The purpose of the invention

The aim of the invention is to improve the efficiency and reliability of transmission, as well as reducing the complexity of the manufacturing process. The efficiency lies in the possibility of using wheels different from each other in size, including sizes that will allow you to raise or lower gear ratio. The possibility of transmission of motion reliability will be ensured by the absence of abrupt change of gear ratio, that will eliminate the overload mechanism.

The invention

The method of transformation of the motion, is that the round body (gear, sprocket, pulley, etc.,) is fixed on the shaft eccentric and enter into interaction with another body. The interaction can be performed directly, for example, the gear with the gear, and through the intermediate element or elements, such as the asterisk with asterisk in the chain passing through the circuit.

For example, when the rotation of the eccentrically mounted on the gear shaft to its various points of the radial surface will describe a trajectory in the form of circles of different diameters, corresponding to the removal of data points from the axis or point of rotation of this gear. If you connect with this surface of the other gear and to ensure constant interaction, thus creating conditions for return (forward, swinging, pivoting) of the movement of this gear, the eccentric gear together and raced to the second, will be to move it from its center of rotation, and then down, pull her to him. Thus, the second gear is transmitted to the motion, without breaking the flow of power from different places of the first gear, which have razlichnyye radii of rotation about an axis fixed on the first gear. Receiving motion from the viewpoints of the first gear, which pass different path (length) for one of its turnover, the second gear will spin it faster, some slower, proportional to the path that passes the point of the first gear, which interacts at the moment the second gear. Eventually, with a uniform rotation of the eccentric gear and the other interacting with it will spin unevenly and Vice versa, if evenly rotate the second gear, unevenly will rotate the eccentric is fixed.

Gear, pulley, sprocket, or other body may have an axial surface (pitch, surface vertices, surface depressions, radial, and others), different or needlecases from the surface of the circular shapes (cylinder, cone and others).

If you want to get traffic with a certain law changes speed, it is possible to apply one non-circular and one round element. Non-circular gear may be coaxially surface differing from the surface of a circular cylinder that can be made in the form of surfaces forming which can be an ellipse or a shape different forms, which will be achieved is necessary is possible to obtain a lower or higher gear ratio with a simultaneous change in the law of motion. In essence, this design can be made in the form of a crank gear, crank-chain or crank-belt mechanism.

In the end, using a round wheel with an offset center (axis) of rotation or pivot point, different parts of the working part (surface) will be held about a fixed point with a different speed, while being moved away from her, approaching her. If fixed eccentric wheel (gear) to enter into interaction (engagement) another body (gear), keeping their relationship and giving the possibility to return (reciprocating, oscillating) movement of an attached gear, the latter will rotate with variable speed, while the eccentric gear will have a constant speed. The transfer can be carried out by raising and lowering the gear ratio, i.e., the wheels can have different sizes.

To change the eccentricity of any wheel at the right time, it is performed by covering the Cam, rotating which change the eccentricity.

In Fig. 1 shows a device for converting motion.

In Fig. 2 depicts a side view of OA consists of a wheel 1, an eccentric mounted on the shaft 2, and interacts with gears 3. The gear 4 is rigidly fixed on the same shaft 5 with the gear 3. The shaft 5 with gears 3, 4 communicates through the bearing 6 with the tab 7 disk 8, which is fixed through a bearing 9 on the wheel 1. At the same time, the shaft 5 is connected via bearings 10, 11 link 12 with the shaft 13, which is fixed to the gear 14.

Work designs

With a uniform rotation of the wheel 1 is constantly interacting with the gear 3 will rotate unevenly, with a smoothly changing speed, doing a backward movement. Located on the same shaft 5, the gear 4 will transmit uneven movement of the gear 14.

Advantages of the invention

The application of this method and device will allow you to convert uniform motion in non-uniform or Vice versa, by applying ordinary round wheels, gears and other parts, easy to manufacture, and to avoid overloading mechanism, which will increase its reliability. The efficiency will be achieved by the transmission of motion over large distances by applying the chain or belt transmission, as well as the ability to increase or decrease transmit what the mechanisms".
