SINGLE TURNOVER

The useful model refers to the mechanisms and prengzanon for the use of locking organs in the Chrea iax of the Permanent Control of the techno-gihexea1MI processes with

The well-known design of the mechanism of the actuator electric one-turn (see the catalog "G | eibory and automation, part 2, Moscow, 1987, pp. 42-44). D |) the operation of the mechanism consists in converting the electrical signal into a rotational one moving on the output shaft. The NfexannBM consists of the following main parts: a gear motor, an inductive signaling unit, or: a resistive, open, plug-in connector: with a digital input, a lever as a drive synchronous kizooborotnye electric motors are used. Turnip, shrimp is made of a molded case, a chat room, a worm box. } Tifaf.1 Egnye with the mechanism of wasps It is displayed with the help of a handle installed: on a worm shaft.

with increased high reliability, for example, in greenhouse huts, which will lead to electrical injuries;

- consumed power and voltage required for powering the electric motors require the use of electric elemental quels, the use of bridged relays and control units, which is not economical;

- our backlash in the mechanism and in the organ resulting in inconvenience of setting the end-breaker unit and to a large inaccuracy in their operation;

-the well-known design has a short travel time of the output shaft of the mechanism and the impossibility of selecting this time for specific technological conditions for a complete replacement of the actuator with another with other parameters.

 The claimed utility model is the elimination of these shortcomings, having carried out the simplification of the constructiveness and facilitation of its maintenance.

This goal is achieved by the fact that the actuating electric single-turn mechanism includes, in Kopnxc with PI modules, a regulator mounted inside, connected to an electrode, mounted on one of the flanges. Another distinctive principle of comparison with the well-known one is that the mechanism has at least two regulators, of which a single-stage oscillator is combined with an electric motor. The gearbox, located in the casing, is fully gear and multi-stage and is equipped with a device for translating the mechanism into manual control. R | the device has a spring-loaded axis, on one end of which a plate is vertically arranged, interacting with spring-loaded gear wheels coaxially connected to each other. At the same time, on one end of the output shaft, there are mounted pfa cams, which can interact with limit switches.

The inventive utility model is illustrated with drawings:

in FIG. 1 - a general view from the side of the mechanism of a self-elucidating eleasphtotic single qpoxIJGO is depicted;

in FIG. 2 - also, in section;

on (| mg. 3 - ishemagicheskoy scheme reuctor gear shogostupenogo;

in FIG. 4 - depicting attachment for translating the mechanism to manual engraving.

The single-turn electric drive mechanism includes a housing 1 with flanges 2 and 3, which are the basis for the installation of 4 cm electric motors {W | JuvanEUYOGO together with gear 5 mounted on flange 2 Reducer 5 through gear 6 is & coaxially connected to gear 7 with six of it 8 located on the input Bajiyf 9 pesz yKTOpa 10 made of gear and multi-stage. The pins 7 and 8 interact with the spring 11 and have rotational and reciprocating motion. Shgshshshshya 8, in its own way, is engaged with gear 12 which is connected to gear 13 and located on intermediate shaft 14 of reel 10. Istring 13 is meshed with 15 coaxially connected to gear 16 mounted on input shaft 9. Chassis 16 in its own , is meshed with gear 17 coaxially connected to gear 18 located on the intermediate shaft 14. Gear 18 is in gear with gear 19, which is rigidly

it is mounted on the output vag 20, on one end of which it is rigidly mounted} juvan control lever 21 with restrictor 22 and a coupling 23, with the help of which the output shaft 20 is connected with a regulating organ, for example, a 3- or 4-way yutapin. At the other end of the outlet 20, hooks 24 and 25 are placed, which can be in contact with the limit switches 26, 27 and 28. The flange 2 of the gearbox 10 is equipped with a grip 29 for translating the mechanism into manual engraving, the axis 30 interacting with spring 31 and placed in guideway 32. The axis 30 has a button 33 at one end, and at the inferior end of the iraxo, the plate 34 is interlocked with the pin 8. 8. Flange 3 is fixed with two buttons 35, on which the support bracket 36 is mounted, by means of which a crack is made Mechashoma with regulation by organ.

The single-turn actuating mechanism works in a lean manner. To start the electric motor 4, it is driven from the current source with a frequency of 50 hertz and a voltage of 22 to 30 volts, the rotation of which through the yoke 5 is transmitted to the gear 6. In this case, the gearbox 5, which is equipped with an electric motor 4, can have a gear reduction in the range from 1 / 15.62 to 1/670, this significantly extends the range of variation of BNTeHii of the full stroke of the output shaft 20. By gear 6 the gearbox 5 transmits the rotational movement of the gears 7 and 8, from which the gears 12 and 13 are driven, transmitting rotational motion to shes thorns 15 and 16. Pashednia, in their own way, carry gears 17 and 18. The rotary 18 is meshed with gear 19 and Tejvi themselves rotate it together with the output shaft 20, which has the effect of being rotated.

V

gun, for example, 3 or 4 way valve. At the same time, the instructive ratio of the gearbox 10 is sogavlyash- 1 / 115.97. Thus, the change in the full stroke time of the output shaft 20 is achieved by pressing the corresponding payroll 5 and the required transfer is clean, which excludes the replacement of the actuator by the drive shaft and the rotation of the output shaft 20 is carried out simultaneously with the rotation of the regrashing body that acts on this or that technological process, in this case, when the output shaft 20 rotates together with the latter, the pivots 24 and 25 rotate and, when reaching the extreme positions, the pivots 24 and 25 act and one of the limit switches 26, 27 and 28, which break the power supply circuit with the electric motor 4. The setting of the end switches is as follows: they turn to the grooves 24 and 25 to the required angle. At the same time, the levers of the operating mechanism and the adjusting mechanism unnecessarily 24 and 25 are placed unobtrusively on the output shaft 20.

In order to adjust the mechanism of the manual hedgehog in p), the retouching body should be able to disengage the gear pin 8 from the gear 12 from the gearing 12. This is carried out by unscrewing the wiring device. First, press the button 33 until one morning; so that the 34 acts on the pinion 8, moves the latter along the axis of the input cotton 9 and brings mecrefaoo 8 out of the hook with the pin 12. Then, with the lever of the alphabet 21, they turn the output 20 to rotate and re-surf body to the desired thaw with fully pressed button 33. When the button 33 is pulled down, spring 31 returns axis 30 together with button 33 to its original position and spring 11 puts pin 8 into gear mesh with pin 12

 The expansive mechanism is mounted on a re-regulating body using the pomp of the reference core 36 rigidly mounted on the bottom 35 attached to the flange 3.

Thus, the claimed technical solution ensures the creation of a positive effect, that is, a new, more reliable resz ltat according to qjasHeMmo with rez / ltat, which is obtained from mechashkma, taken as a 1 phototype of the claimed constructstsatl; MECHANICAL COMMUNICATION allows using small-sized and low-power relays and control units as a driving ashkra, which allows us to use more children switching equipment. D) aklika that with prolonged stops caused by jamming of the regulatory body, the likelihood of failure of the executive mechanism is significantly reduced. A supply voltage of 24 volts allows maintenance personnel to work without the risk of electric injuries. The executive mechanism: this design allows you to completely eliminate the need for expensive regulators to maintain a specified control accuracy.

At the same time, it should be noted that the listed distinctive features of the claimed utility model in the course of the infusion and patent search at the technical level were not detected, therefore, I MAY conclude that the claimed utility model meets the novelty conditions

This serial scam of executive mechanisms was made in the conditions of the state enterprise of the state farm “Tepli shm and, when exited, showed interesting results,

) I’m upgrading lero, we can conclude, Dep, u:) It is perfectly applicable.
