Description

The invention relates to the field of manufacturing helical spirals, namely to spiraling machines (devices), with which the deformation of the wire (material) is achieved by winding it onto a continuous core.

A known method of manufacturing helical spirals (M.S. Kaufman, A.A. Kuznetsova, Yu.A. Khrunichev. Production of spirals, grids and bushings of electric vacuum devices. Moscow-Leningrad, Gosenergoizdat, 1962, pp. 37-44), including fixing tungsten wire on a continuous core, winding it when reporting rotational-translational motion of the core, cutting the spiral together with the core wire by the piece, removing pieces of core wire from the spiral by their joint etching in acid.

The implementation of this method is carried out using a device (spiraling machine SG-3) containing a core winding mechanism, a coil with coiled material, a core moving mechanism, a transmission configured to transmit rotation from the engine to the driven element of the core winding mechanism and to the driven element of the moving mechanism core.

The disadvantages of this method are the small productivity of the full cycle of manufacturing helical spirals, the limited range of materials used for their manufacture (the method cannot be used for the manufacture of spirals, for example, from materials that dissolve in acids), and the relatively high financial cost of their manufacture. This is due to the fact that for the manufacture of helical spirals from tungsten wire, you must have:

- special equipment for etching in acid sections of a continuous core wire when they are removed from a helical spiral (tungsten does not dissolve in acid);

- regularly replenished consumables (core wire and acid).

The well-known (USSR AS No. 218801, B21F, 04/10/1967, published in BI No. 18 dated 05/30/1968) a method of manufacturing helical spirals includes fixing the material on the core, communicating rotational-translational movement of the core, feeding the material and winding it on the core, removing the spiral from the core using the stop (knife).

The disadvantages of this method are:

- low productivity due to the intermittent cycle of the manufacture of springs;

- financial costs for regularly replenished expendable material (core wire);

- the complexity of the technological operations involved in the manufacture of spirals;

- the unreliability of removing the spiral from the core, which formed a console when approaching the stop (knife).

A known method is selected for the prototype.

It is known (UK patent No. 803542, class NKI 83 / 4E, publ. In o / b "Industrial property" ("Listes"), 1956) a device for winding a spiral spiral containing a core winding mechanism, a coil with a winding material and a movement mechanism core.

The disadvantage of this device is its low reliability.

The known (USSR AS No. 925492, B21F 3/04, B21F 35/00, dated March 31, 1980, published in BI No. 17 of 05/07/1982) a device for winding a helical spiral onto a continuous core contains mounted on the bed along the way technological process core winding mechanism, a coil with winding material and core moving mechanism.

The disadvantage of this device is that it does not provide a complete production cycle of helical spirals (see above, similarly with the disadvantages of the SG-3 spiraling machine).

The known device is selected for the prototype.

The known (USSR AS No. 218801, B21F, dated 04/10/1967, published in BI No. 18 dated 05/30/1968) a device for removing a helical spiral from a core contains a stop.

A disadvantage of the known device is its unreliability in the manufacture of springs with a small inner diameter due to the fact that:

- the core section with the spiral wound after passing through the collet forms a cantilever that, in contact with the stop (knife), will bend under the action of the force applied to the core and the spiral, preventing this release of the spiral from the core;

- the emphasis is made in the form of a knife, the blade of which has a sufficiently large thickness compared to a sharp working edge, while the large thickness of the blade will prevent the separation of the spring with a small inner diameter and core thread.

The known device is selected for the prototype.

The problem solved by this group of inventions is to achieve the possibility of manufacturing a helical spiral with a small inner diameter from various materials, for example, organic and inorganic or from ferrous and non-ferrous metals, to increase the productivity of its manufacture and reduce the cost of its manufacture.

The technical result achieved using the present group of inventions is:

- in combining the spiraling of the material onto a continuous core with the uninterrupted removal of a finished helical spiral from a continuous core (achieving a qualitatively new basic technical characteristic of the method, device and device);

- to increase the reliability of removing the helical spiral from a continuous core (achieving improved basic technical characteristics of the device);

- to increase the accuracy of manufacturing the pitch of the helical spiral (achieving improvement in the basic technical characteristics of the mechanism).

The above technical result is achieved by the fact that:

- in the method of manufacturing helical spirals, including fixing the material on the core, communicating rotational-translational movement of the core, winding the helical spiral onto the core, removing the spiral turns from the core using the stop, additionally, first, a continuous core is manually passed through the reel manually. When the extreme turn at the free end of the spiral approaches the stop, the core movement with the spiral wound around it is stopped. Manually removed from the core, at least one extreme turn. Then, the emphasis is brought into contact with the extreme coil of the spiral located on the core so that it impedes the movement of this coil of the spiral together with the core. In this case, an emphasis is placed so that it also prevents the rotation of the spiral coil taken from the core around the axis of symmetry of the core working section. After that, continuous removal of the spiral turns from the core is carried out by resuming the rotational-translational movement of the core;

- a device for winding a helical spiral onto a continuous core, comprising a core winding mechanism mounted on the bed during the process, a coil with the material being wound, and a core moving mechanism, which is additionally equipped with a reel and a stop, which are mounted on the bed during the process. In this case, the reel is made with the possibility of restricting the slipping of the spiral coils relative to the core, and the stop - with the possibility of restricting the movement of the extreme coil at the free end of the spiral together with the core and the rotation of the spiral coil removed from it around the axis of symmetry of its working section. The coil with winding material may be equipped with a deflecting roller located on the working section of the core between the core winding mechanism and the reel. It can be equipped with a helical spiral receiving unit located between the stop and the core moving mechanism. It can be equipped with a transmission configured to transmit rotation from the engine to the driven element of the core winding mechanism, to the driven element of the reel, to the driven element of the continuous core moving mechanism;

- a mechanism for moving a continuous core containing a spindle, a driven element, a coil and a bed, is additionally equipped with a guitar, the base of which is connected to the spindle. In this case, the input link of the guitar, coaxial with the axis of rotation of the spindle, is rigidly fixed to the bed, and the output link of the guitar is connected to the coil;

- a device for removing spiral coils from a continuous core, containing a stop, is additionally equipped with a reel made of at least two kinematic rotational pairs located in front of the stop. Moreover, in the second pair, the part mounted on the driven element of the first pair with the possibility of rotation is completely or partially covered by a continuous core. The axis of rotation of both pairs is perpendicular to each other, and the axis of rotation of the driven element of the first pair coincides with the axis of symmetry of the core. The working section of the stop, located at an angle to the continuous core, is made with the possibility of preventing the movement of the extreme turn on the free end of the spiral wound on the core, and the rotation of at least one coil of the spiral taken around the core around the axis of symmetry of the working section of the core. The detail of the second kinematic pair can be made in the form of a body of revolution, mounted on the driven element of the first pair with the possibility of the formation of friction coupling with a continuous core. A detail of the second kinematic pair can be made, for example, in the form of a sprocket or a gear. The emphasis can be made in the form of a part with a cross section of small dimensions, for example, with a diameter of not more than 400 microns, in comparison with its length. The emphasis can be made in the form of a plate, for example, with a thickness of not more than 400 microns. The angle between the working parts of the stop and the continuous core can be 90 °.

The winding of the material using a continuous core, made in the form of a stretched wire (thread, fishing line, etc.), made it possible to apply force effects to the turns of the spiral being wound, sufficient to remove them from the core. Improving the reliability of removing spiral coils from a continuous core is ensured by the fact that when applying force to the spiral coils:

- the position of the working part of the continuous core relative to the parts of the device remains unchanged;

- Passing the core through the reel limited the possibility of slipping the turns of the wound spiral relative to the core. The cessation of the movement of the core with a spiral wound on it, when the extreme turn at the free end of the spiral approaches the stop, made it possible to manually carry out at least one turn on the free end of the spiral being wound from the core. Putting the stop in contact with the extreme spiral coil located on the core in such a way that it impedes the movement of this spiral coil together with the core, provided the first condition for the removal of the spiral turns from the core. Placing the stop so that it also prevented the rotation of the spiral coil taken from the core around the axis of symmetry of the core working section provided the second condition for the implementation of removing the spiral turns from the core. The resumption of the rotational-translational movement ensured the continuation of the material winding onto the core, the supply of the coiled spiral turns to the stop and the implementation of uninterrupted removal of the coiled spiral coils from the core with its help. The proposed new set of features of the method provided a qualitatively new result, namely, the implementation of uninterrupted removal of the spiral from a continuous core during the winding of material on it. The removal of spiral turns is carried out by screwing them from a continuous core.

The supply of the device with a reel provided the possibility of realizing the supply of wound turns of the spiral to the stop with the restriction of their slipping relative to the continuous core. The supply of the device with emphasis made it possible to apply force to the extreme turn of the helical spiral (turn B) located on a continuous core, and to the turn of the same spiral freed from this core (turn A). As a result of power actions, coil B is limited in movement together with a continuous core, and coil A is limited in rotation around the axis of symmetry of the working section of this core. The proposed new set of features of the device provided a qualitatively new result, namely, the possibility of implementing uninterrupted removal of the spiral from a continuous core during the winding of material on it. In the case of supplying the device with a deflecting roller located on the working section of the continuous core between the core winding mechanism and the braking mechanism of the helical spiral, material can be supplied to the continuous core in a predetermined location. In the case of supplying the device with a receiving unit for a helical spiral removed from a continuous core, a coiled spiral can be supplied to a predetermined place, for example, into a receiving container or to a spiral cutting device. If the device is equipped with a transmission capable of transmitting rotation from the engine to the driven element of the core winding mechanism, to the driven element of the reel, to the driven element of the core moving mechanism, the number of engines used can be reduced to one.

The supply of the mechanism for moving the core with a guitar made it possible to obtain different speed ratios between the translational and rotational movements of a continuous core, the value of which depends on the step size of the manufactured spiral. The connection of the base of the guitar with the spindle ensured its rotation during rotation of the driven link. The connection of the input link of the guitar with the base made it possible to rotate its gears. The connection of the output link of the guitar with the coil ensured the rotation of the coil at the speed necessary to obtain a predetermined step in the winding spiral. The proposed new set of features of the mechanism provided a new result, namely, the achievement of an improvement in its basic technical characteristics by performing a step between adjacent turns of a helical spiral with a given accuracy.

The supply of the device with a reel made of at least two kinematic rotational pairs located in front of the stop made it possible to approach the stop of the coils of a helical spiral with the restriction of their slipping relative to a continuous core. The execution in the second pair of parts mounted on the driven element of the first pair with the possibility of rotation, fully or partially covered by a continuous core, provided the possibility of interaction between these parts and turns of a wound spiral. For this, the rotation axes of both pairs are perpendicular to each other, and the rotation axis of the driven element of the first pair coincides with the axis of symmetry of the core. If the details of the second kinematic pair are made in the form of a body of revolution mounted on the driven element of the first pair with the possibility of frictional coupling with a continuous core, it is possible to feed various spirals that differ in magnitude of the pitch between the turns. In the case of the execution of the details of the second kinematic pair in the form of, for example, a pinion gear or a gear wheel, it is possible to supply spirals with the same pitch between the turns (corresponding to the distance between the teeth or the pin). The implementation of the working section of the stop, located at an angle to the continuous core with the possibility of preventing the extreme turn from moving on the free end of the spiral wound on the core and the rotation of at least one coil of the spiral taken around the core around the axis of symmetry of the working section of the core, provided the core to be removed from the core turns to the stop coils of a winding spiral. The emphasis in the form of a part with a small cross-section, for example, a diameter of not more than 400 microns (option 1), compared with its length or as a fixed plate with a thickness of not more than 400 microns (option 2) made it possible to remove spiral coils from a continuous core small inner diameter. The location of the working parts of the support and the core at an angle of 90 ° relative to each other provided the best conditions for removing spiral coils from a continuous core. The proposed new set of features of the device provided a new result, namely the implementation of uninterrupted removal of the spiral from the core during the winding of material on it.

Figure 1 shows a device for winding a helical spiral onto a continuous core (kinematic diagram); figure 2 is the same, a spiral spiral wound on a core; figure 3 is the same, a helical spiral with manually removed from the core, at least one turn (a thin line shows that there can be more shot turns); figure 4 - the same emphasis, located in the working position relative to the core with a helical spiral wound around it and with the turns taken off the core during its movement; figure 5 is the same, the core winding mechanism; figure 6 is the same, the friction reel and emphasis located along the process; Fig.7 is the same, the mechanism for moving the core.

A method of manufacturing helical spirals is carried out using the device (see figure 1). In the manufacture of the spiral 1 (see FIG. 2), a material 2 with a cross section of small dimensions compared to its length is used as a preform, for example, a metal wire, a thread obtained from organic or inorganic substances (long material).

The method includes securing the material 2 on the core 3, communicating the core 3 with rotational-translational motion, feeding the material 2 and winding it onto the core 3, removing the spiral 1 from the core 3 using the stop 4 (or stop 5).

Winding onto a cantilever mandrel (core) with a diameter of less than 0.4 mm is a difficult task due to the complexity of manufacturing such a mandrel and its frequent breakdown when winding material on it. The winding of helical spirals, for example, of a metal wire with a diameter of less than 0.2 mm by known methods, is carried out in most cases on a continuous core with a diameter of not more than 0.4 mm.

First, a continuous core 3 is passed through, for example, a friction reel (see Figs. 1 and 7). When fixing material 2 on the core 3, it can also be passed through the reel. After the beginning of the winding of material 2 on the core 3, the passage of the free end of the winding spiral 1 through the reel and its approach to the stop 4 (or 5), the core 3 is stopped. At least one turn A is removed from the core 3 from core 3 (see figure 3). The turn A of the spiral 1 is removed from the core manually by using the elastic properties of the material being wound 2 or, if this material does not have elastic properties, by deforming the coil. Set the stop 4 (see Figs. 1 and 7) or the stop 5 (see Fig. 4) so that it is in contact with the coil B of the spiral 1 located on the core 3, in the future when the rotational-translational movement of the core 3 is resumed had the ability to prevent the translational movement of the extreme turn B of the winding spiral 1 together with the core 3, as well as to prevent rotation of at least one turn A of the spiral 1 freed from the core 3 around the axis of symmetry of the working core 3. After that, the resumption of rotational-translational motion ke 3 is carried out nonstop coiling core material 2 to 3 and has a smooth converging spiral coils 1 in sequential contact with their focus 4 (or 5 with emphasis).

The process of removing the turns of the spiral 1 from the continuous core 3 proceeds as follows.

After the resumption of the rotational-translational motion of the continuous core 3, all the turns of the winding spiral 1 located on the core 3, except for one turn of B, perform a rotational-translational motion together with the core 3. An emphasis 4 (or an emphasis 5), limiting the translational motion of the coil B in contact with it, does not interfere with the rotation of this coil. In this case, the rotation is transmitted to at least one coil A of the spiral 1, taken from the core 3. The axis of rotation of the coil A of the spiral 1 is located at an angle γ to the common axis of rotation of the spiral 1 and core 3 in its working section. At the same time, stop 4 (or stop 5) limits the rotation of coil A around the axis of rotation of the working section of core 3. As a result, coil B is removed from core 3 by screwing it up, and after it all subsequent turns of spiral 1 that come into contact with focus 4 (or focus 5).

The device (see Fig. 1) contains a mechanism (see Fig. 5) for winding a continuous core 3 mounted on a bed 6 along the technological process, a coil 7 with winding material 2 and a mechanism (see Fig. 6) for moving the core 3. Also there are, for example, a friction reel (see Fig. 7) and a stop 4 (or a stop 5). They are placed on the working section of core 3 in the process.

The mechanism (see figure 5) of the winding of a continuous core 3 consists of a spindle 8, a driven element 9 made in the form of a gear wheel, a coil 10, elastic-brake elements 11 and 12, a guide roller 13. The spindle 8 connected to the driven element 9 mounted on the frame 6 using bearing bearings 14 and 15. The coil 10 is mounted on the axis 16, mounted in the spindle 8.

The coil 7 can be mounted on the frame 6 using bearing bearings (not shown) or made in the form of a separate unit, designed to work together with the device. The supply of material 2 from the coil 7 to the continuous core 3 can, for example, be carried out through a deflecting roller 17 located on the working section of the core 3 between the core winding mechanism 3 and the reel (see Fig. 7).

The friction reel (see Fig. 7) is a working body for supplying the turns of the spiral 1 to the stop 4 (or to the stop 5) and limiting their displacement relative to the continuous core 3 during removal of the extreme turn B of the spiral 1 from the core 3 and its removal from it .

Friction reel (see Fig.7) is made of at least two kinematic rotational pairs. In the first pair, the driven element 18, made in the form of a gear wheel, is mounted for rotation around the axis of symmetry of a continuous core 3 in its working section. The driven element 18 is installed in the frame 6 on the bearings 19 and 20. In the second pair, a body part 21 of the type of rotation mounted on the driven element 18 of the first pair rotatably around an axis perpendicular to the axis of symmetry of the core 3 working section is installed with the possibility of friction coupling with core 3 wrapping around it, at least in part.

Part 21 can be made, for example, in the form of a drum mounted on an axis 22 fixed in an arm 23. An arm 23 is mounted on a driven member 18. The axis of rotation of such a drum is perpendicular to the axis of rotation of the driven member 18, and its outer cylindrical surface may or may not coincide coincide with the common axis of rotation of the driven element 18 and the continuous core 3 in its working area.

The frictional connection between part 21 (drum) and continuous core 3 can have various designs. The core 3 can once completely bend around part 21 (see Fig.6). In another embodiment, the core 3 can partially bend around the outer surface of the part 21. In this case, two rollers can be used to grip the part 21 with the core 3, which ensure that the core 3 is pressed against a part of the outer surface of the part 21 (not shown, since it is widely known in the art decision).

Running a reel with friction coupling is not a prerequisite. If the reel is designed to feed the spiral coils of the same size (the pitch between the coils) to the stop, the part of the second kinematic pair can be made, for example, in the form of a gear wheel or sprocket (not shown).

The emphasis 4 can be made in the form of a plate (see figure 4) with a thickness of not more than 400 microns. In this case, the working face of the plate is located at an angle to the continuous core 3 with the possibility of preventing the translational movement of the extreme turn B of the spiral being wound 1 together with the core 3 and preventing rotation of at least one turn A of the spiral 1 released from the core 3 of the core, freed from the core 3. The optimal angle between the working face of the stop 4 and the working part of the core 3 is 90 °.

The stop 5 can be made in the form of a part with a cross section of small dimensions, for example, with a diameter of not more than 400 microns, compared with its length, for example, from a wire (or thread). In this case, the stop wire is located at an angle to the continuous core 3 with the possibility of preventing the translational movement of the extreme turn B of the spiral being wound 1 together with the core 3 and preventing rotation of at least one coil of the spiral A freed from the core around the symmetry axis of the working section of this core 3. In this case, the wire (thread) should be fixed at one end to the bed 6. Its other end can be connected to a load 24 (see Fig. 6) or a spring (not shown) for tensioning the stop wire 4. The optimum angle between the wire m stop 5 and the working part of the core 3 is 90 °.

When making a stop in the form of a wire console (not shown), the stop wire should have sufficient rigidity to provide the conditions necessary to ensure the removal of the turns of spiral 1 from continuous core 3.

The mechanism (see Fig. 6) for moving the core 3 comprises a spindle 25, a driven element 26 made in the form of a gear, a coil 27, a guide roller 28 and a bed 6. The spindle 25 and the driven element 26, rigidly connected to each other, have a common axis rotation. The spindle 25 is mounted on the bed 6 with the help of bearing bearings 29 and 30.

The core moving mechanism 3 is equipped with a guitar for installing removable blocks of gears 31, 32, 33, 34, 35 and gear 36. The base of the guitar is made in the form of plates 37, 38 connected by several studs (not shown). The blocks of gears 31, 32, 33, 34, 35, made with the same dimensions, consist of a gear and gears interconnected. The blocks of gears 32, 34 and gear 36 are mounted on the axis 39 with the possibility of free rotation. The blocks of gears 31 and 33 are mounted on the axis 40 with the possibility of free rotation. The block of gears 35 is mounted on the axis 41 with the possibility of free rotation. In this case, the input link 42, made in the form of a gear (see Fig.6), is located coaxially with the axis of rotation of the spindle 25 and is mounted on the frame 6. The output link 43, made in the form of a bevel gear, is connected to the coil 27 through a bevel gear 44 The gear wheel 36 and the output link 43 are rigidly connected to the axis 39.

Plate 37 (part of the base of the guitar) connected to the spindle 25, formed a kinematic rotational pair with a bed 6.

The gear ratio of the guitar determines the step of the winding spiral 1. The selection of the desired gear ratio of the guitar is carried out by replacing its interchangeable gear blocks.

The transmission consists of a primary shaft 45, an intermediate shaft 46 and gears 47, 48, 49, 50. The primary shaft 45 is connected to an electric motor 51 through a clutch 52, with an intermediate shaft 46 through gears 47 and 48. Gears 48, 49, 50 parallel connected respectively with driven elements (gears) 9, 17, 26.

A continuous core 3 wound on a coil 10 is passed through a guide roller 13, the central hole of the spindle 8, the central hole of the driven member 17, the central hole of the spindle 25 and through the guide roller 28. The free end of the core 3 is mounted on the coil 27. As a core 3, it can used, for example, metal wire. The straight section of the core 3, located between the part 21 (drum) and the driven element 26, is a working section. In this case, the axis of rotation of the core 3 coincides with the axes of rotation of the spindle 8, driven elements 9, 17, 26 and spindle 25. The exception is the part of the straight section of the core 3, wound on part 21 of the friction reel (see Fig. 7). The core wire 3 at least partially bends around part 21 (drum).

The receiving unit 53 of the spiral 1, made in the form of a tube mounted on the frame 6, can, for example, be used to supply the spiral 1 to the cutting device or to direct the spiral 1 with tightly wound turns to a collection container (not shown).

The device operates as follows.

The free end of the material 2 is fixed on a continuous core 3. Then the electric motor 51 starts to work, which transmits the rotation to the spindle 8, the driven element 18, the spindle 25, the base of the guitar (plates 37 and 38) with the parts fixed to them. The input link (gear) 43 of the guitar remains stationary. As a result, the blocks of gears (in the guitar), rotating around their axes, cause the output link (bevel gear) 43 to rotate, which, in turn, causes the bevel gear 44, and with it the coil 27, to rotate. core 3 rotates and moves forward, reeling from coil 10 and simultaneously winding onto coil 27.

At the same time, material 2, the end of which is fixed on a continuous core 3, is wound from a coil 7 and wound onto a core 3. At the same time, a spiral 1 made of material 2 performs a rotational-translational movement together with core 3. After the passage of spiral 1 together with the core wire 3 through part 21 and approaching it to the stop 4 (or to the stop 5), the electric motor 51 is turned off. Kern 3 and spiral 1 stop the movement. At least one turn A is removed from the core 3 at the free end of the spiral 1. The stop 4 (or the stop 5) is brought into contact with the extreme turn B of the spiral 1 located on the core 3. The electric motor 51 is turned on again. Material 2 is wound onto the core 3 and the coils of the spiral 1 together with the core 3 perform rotational-translational movement towards the stop 4 (or to the stop 5). The stop 4 (or stop 5) limits the possible movement of the turns of the spiral 1 together with the core 3, not allowing the turn B to move further together with the core 3. At the same time, the stop 4 (or stop 5) prevents the rotation of the turn A around the axis of symmetry of the working part of the core 3 and does not prevent its rotation around its own axis of symmetry, located at an angle γ to the axis of symmetry of the working part of the core 3.

When the stop 4 (or stop 5) acts on the coil B of the spiral 1, the friction reel does not allow the turns of the spiral 1 to move in the opposite direction from the stop 4 (or the stop 5), since the continuous core 3 and the spiral 1, wound on the part 21, formed between itself and this detail frictional connection. As a result, the turn B in contact with the stop 4 (or with the stop 5), rotating around the axis of symmetry of the core 3, transfers rotation to the turn A of the same spiral, freed from the core 3, the axis of symmetry of which is located at an angle γ to the axis of symmetry of the working part of the core 3. When the turn of A rotates around its axis of symmetry, the turn of B comes from the core 3 by screwing it up, followed by it, and so on. Thus, when the rotational-translational movement of the core 3 is resumed, uninterrupted winding of the material 2 onto the core 3 and removal of the turns of the helical spiral 1 from it when they come into contact with the stop 4 (or with the stop 5) are carried out. The free end of the helical spiral 1, removed from a continuous core 3, is inserted into the receiving unit 53.

The use of this group of inventions made it possible to obtain a method that is implemented using a device that includes a mechanism and a device (options) that ensure the achievement of a new task, namely:

- combining the spiraling of the material onto a continuous core with the uninterrupted exit of a finished helical spiral from it (achieving a qualitatively new basic technical characteristic of the method, device and device);

- improving the reliability of removing the helical spiral from a continuous core (achieving improved basic technical characteristics of the device);

- improving the accuracy of manufacturing the pitch of the helical spiral (achieving improved basic technical characteristics of the mechanism).
