The invention relates to the field of electrical engineering and can be used for SZ twisting pie lived power cables and multi-pair of cores of the cables.

The known device mnogonitochnoy SZ twisting of cables [1] Twisting multiple cores is made between stationary distribution outlet and twisting caliber, between which consistently set the intermediate rotating socket and twisting socket [2] Twisting lived is carried out at a constant linear velocity of the core and periodically synchronous UB>i: must be less than 180o. The main disadvantage of the above device for SZ stranding is impossible to perform the twisting pie lived.

Closest to the proposed invention the technical essence is the device SZ twisting, which in rotating outlets torsional framework established guides in the form of a profiled roller [3]

This device is selected as a prototype. The main disadvantage of this device is that it allows symmetrically oriented sector veins when they log in twisting caliber.

The goal is to develop a device mnogonitochnoy twisting, allowing the SZ twisting pie lived.

In Fig.1 schematically shows a device for SZ twisting pie lived in Fig. 2 scheme of the rotating socket; Fig.3 scheme of the guide sockets in the form of a cylindrical sleeve of Fig.4 scheme of the guide sockets in a pair of parallel profiled rollers; Fig.5 scheme of the guide with the spherical outer surface of the sleeve; Fig.6 scheme twisting of the socket; Fig.7 scheme guide distribution outlet.

In Fig. 1 device in technical sequence is etki 3, 4, 5, 6 and outlet 7, premiline nodes 8, twisting caliber 9, the ribbon rod 10, a receiver 11, a reversible drive sockets 12.

A few lived 13 are given with aldatzeko 1 and twisted in the core 14. The pulley 15 causes the rotation of the disk 16 (Fig.2) outlets 3-6. In the pivot bearings 17, 18 (Fig.2) set the torsion of the frame 19.

Frame equidistant from each other and are located on a circular trajectory relative to the center of the rosettes. Two pins 20 has a housing 21 having the ability to oscillate relative to the plane torsion of the frame 19. In the housing 21 posted by sleeve 22 with the profile of the guide 23, which rotate together about the longitudinal axis of the housing 21.

In Fig.4 and 5 represent alternative guides.

A pair of profile rollers 24 and 25 are mounted parallel to the axes of the brackets 26 and 27, the sleeve 22.

The sleeve 22 together with the rollers 24 and 25 is capable of rotational movement about the longitudinal axis of the housing 21, which may perform an oscillatory motion relative to the plane torsion of the frame 19.

Torsional frame 28 of the spherical hinge (Fig.5) is installed in the disk 16 on the pivot bearings 17, 18. Ball bushing 29 in the direction.

Twisting the socket 7 (Fig.6) consists of two parallel disks, the inlet 32 and outlet 33, which flanges cage frame 34. Between the discs 32 and 33 in alignment with the guide disk 32 and 33 is set premiline nodes 8, reinforced connecting ring 35.

The device SZ twisting lived operates as follows. In initial position the guides outlets 3-7 (Fig.1) are set so that the axis extending lived from the distribution of the socket 2 to the output disc 33 twisting outlet 7 were horizontal and parallel.

When filling pie conductor 13 is retracted from the radiating device 1 and extend through the guide 36 distribution of the socket 2, and the axis of symmetry of the cross-section of the conductor passing through the top, was directed to the center of the circle, where the guides 36.

Next, the wires pass through the guide sockets 3-6, guides the input disc 32, premiline nodes 8 and directing the output disc 33. Then the wires 13 are collected at the entrance to twisting caliber 9, the cylindrical core 14, which extends through the rod 10 and is supplied to the receiver 11.

The process of twisting is carried out at a constant linear is nick 11 (traction drives and receiver not shown).

Reverse the actuator 12 rotates the pulleys 15 and wheels 16 intermediate outlets 3-6, the disks 32, 33 twisting of the socket 7. When the rotation of the disk is forced torsional rotation of the part 19 of the housings 21, bushings 22, the profile of the guides 23, which rotate through them veins 13. Similarly, the operation in the case of the use of the profile rails 24, 25 or 30, 31.

The device (Fig.1) has three sections.

The area between the junction plug 2 and the output disk 32 twisting of the socket 7. This plot is a plot of preliminary helical twist and spin of each of the wires 13. This site is a kind of drive that determines the number of revolutions in an unchanged direction of twisting of the socket 7.

The area between the input disc 32 and the output disc 33 twisting of the socket 7 is a plot of editing and balancing provisions cross-sectional lived relative to the center of the output disc 33, premilinary nodes 8. The peaks of the cross-section of the pie lived should be directed to the center of the disk 33.

The area between the output disc 33 and twisting caliber 9 is a plot twisting core final Avatele installed socket 3-7 has a different angular velocity, determined by the increment of the angle of twist of the strandsi. The angle incrementimust be less than 180o.

Cut the wires between the guide 36 distribution of the socket 2 and the disk 16 of the socket 3 is rotated at a tangent to the generatrix inclined cone, the apex of which is the guide 36, and the base path of rotation of the guide 23.

The segment between the sockets 3 and 4 4 and 5 5 and 6 6 and 7 rotates by forming an obliquely truncated cone between the sockets, the bases of which are the path of rotation of the guides 23. When the longitudinal movement of the core and the rotation of the sockets 3-7 left on the preliminary site receives lived spiral spin in z-direction length of the twisted segment between the distribution rack 2 and the socket 3, and between the sockets 3-4, 4-5, 5-6, 6-7 is variable and corresponds to the change in the length of the generatrix inclined cones. When the twist length of the twisted segment increases, and when the promotion is reduced. Thus, when the spiral spin lived they receive variable pitch and angle of twist. As a consequence, the longitudinal speed of movement lived at the twist and promotion is a variable value.

When odnovremenno surface.

In twisting the socket 7 wires 13 become parallel, premiline nodes 8 rightouse and oriented relative to the longitudinal axis twisting caliber 9 so that the axis of the cross-section of the conductor passing through its top, was perpendicular to it. During the rotation of the left intermediate outlets 3-6 and twisting of the socket 7 of the conductor 13 is twisted in the left direction Z, and the core is twisted in the right direction type S.

Simultaneous reverse rotation of the twisting of the socket 7 and the intermediate torque sockets 3-6 veins 13 first spin up, and then twisted in the direction of type S, and the core is twisted in the opposite direction of type Z.

The number of turns of the twisted core in one direction is determined by the number of intermediate torque outlets, as well as twisting of the socket, i.e.

mi= 2Kii/ ini= const

or mi= 2i/

where mithe number of coils, twisted in the same direction S or Z;
