Description

The invention relates to mechanical engineering, in particular to devices for converting a single movement type to another or similar, but with different parameters.,

The purpose of the invention is to increase the reliability and load capacity by changing the shape of the working elements,

Fig. 1 shows a JQ motion transform for converting a rotational motion into a rotational motion with a different speed; fig 2 is the same section; fig. 3 - the same embodiment. five

The motion transducer can be designed to convert rotational motion into reciprocating and vice versa, rotational motion into rotary motion with another speed, rotational motion, into unidirectional or multidirectional linear motion and vice versa, reciprocating motion into similar with other gauges unidirectional linear movement.

Depending on the type of movement being converted, a motion converter may have a different (at least two) 30 number of parts, their form depends on the type of movement.

Motion transducer contains T case 1, in which shafts 2 and 3 are placed, three parts 4, 5 and 6, Parts 4 35 and 6 are made in the form of rings and fixed respectively on shafts 2 and 3. Part 5 has a jumper: 7, -ktora is placed on the guides 8 installed in the housing 1. On each part 40 there are working elements. The latter are made in the form of sector parts of screws and nuts placed in pairs on each part and in each pair having different thread directions. On part 45, sector parts 9 and 10 screws are placed on part 5 — sector parts 11 and 42 nuts interacting respectively with sector parts 9 and 10 screws of part 4, as well as section 5 and part 13 and 14 screws.

Part 6 contains sector parts 15 and 16 nuts, which interact respectively with sector parts 14 part 5 screws. The number of pairs of 55 sector parts of screws and nuts interacting with each other can be selected depending on the required reciprocating law

movements of part 5, the length of the sector parts of screws and nuts on parts 4, 5 and 6 in each pair along the axis of the motion converter can be different, but necessarily equal to the length of the sector, parts interacting with them, screws and nuts placed on another part also depending on the required motion conversion law.

The movement of the part 5 is limited to the support surfaces 17 and 18 of the housing, or other types of stops (not shown) may be used.

FIG. 3 shows an embodiment of a motion converter, where the mechanical interaction of parts is replaced by a magnetic one. For this, the sector parts of screws and nuts of at least two parts 4 and 5 are placed with a radial clearance of AND, and at least part 5 has a magnetic excitation system installed, for example, in the form of a permanent magnet 19 and (or) magnetic windings 20. A separating protective partition (not shown) can be placed in a radial gap.

To ensure a long (unlimited) straight-line movement, at least one of the parts is flat (for example, in the form of a corresponding strip between the rails), and the work items are placed on its flat surface sequentially along its length, and the second part is connected .an with reciprocating drive (not shown).

For greater reliability of operation of the motion converter due to guaranteed passage of its part on the set of dead spots, it is advisable to install in parallel two systems of parts whose working elements are out of phase. (Not shown)

As the leading elements of the converter, any of the parts 4. 5 or 6, can be used. Motion can also be removed from any of the specified parts. This makes it possible to connect the motion converter directly to the engine working parts without using additional conversion mechanisms, for example, the pistons of the internal combustion engine, to the rotor shaft or electric motor, etc. A version with flat parts, especially with a magnetic potential.

By prediction, the proposed converter can be used in combination with a conventional engine of almost any kind instead of linear electric motors, which, especially at low speeds, have a very low efficiency value.

The magnetic excitation system has the advantage that the motion transducer can combine the properties of a transducer and a maximum torque coupling at the same time. In order to increase the efficiency, magnetic excitation is advisable to be placed on those parts, the mutual displacement of which takes place at a higher speed (lower moment),

The sector parts of the screws and nuts can be hinged-screw (not shown).

The motion converter operates as follows.

For example, with the driving part 4, the rotation of the sector part 9 of the screw is converted into axial movement of the sector part 11 of the nut part 5 and at the same time the part 5 itself.

9 and 11 with almost no gap are engaged in the sector part

10-screw part 4 and sector part

12 nut details 5, and the latter receives a movement in the opposite direction. The movement of part 5 is limited by support surfaces 17 and 18. The interaction of part 5 with part 6 occurs in reverse order. Behind . by varying the thread parameters of the sector parts of the screws and nuts of the parts, the rotational speed is converted.

Part 5 may also lead. In this case, parts 4 and 6 rotate at different speeds. With the flat execution of one of the parts, the rotation of the leading part or its reciprocating movement can be transformed into an unlimited one

directional or reversible (depending on the working conditions) linear movement of the driven part, and at fixed fixing of the flat part the base, for example a car (not shown), on which the drive with the driving part is attached, can move.
