The inventive device for testirovanie superconductor contains attatck, twisting of the frame, the receiver and the device located between the torsion frame and receiver. The device is made in the form of a roller, mounted in a rotating sleeve, whereby rotation direction and rotation of the torsional frame opposite. 1 Il.

The invention relates to the technical equipment used in the production of composite superconductors.

A device containing attatches with the brake element, rotating the drum, kinematically associated with electric traction units with bypass roller, fiber nodes, the receiver (ed.St. USSR N 990005, CL N 01 In 13/00).

A device containing attatck, drive, kinematically associated external torsion of the frame, the associated internal torsion of the frame, and the receiver. The relationship between internal and external torsion part through the motor by a hard C is e the solution requires the use of special motor and dvuhnitochnogo torsion device of high complexity with additional control system.

The aim of the invention is to simplify the design of the device while increasing reliability.

This is achieved in that in a device for testirovanie superconductor with a low level of residual stresses containing attatches torsion frame and receiver, added torsional device located between the torsion frame and receiver kinematically associated with torsional frame and are made, for example, in the form of a roller, mounted in a rotating sleeve, the direction of spins additional twisting device and torsion of the frame opposite.

The drawing shows a functional diagram of the device for testirovanie superconductor.

The device comprises attatches 1, torsion frame 2, the receiver 3. Between torsional frame and receiver installed additional twisting device 4 made in the form of a roller 5, is fixed in the rotating sleeve 6. Testiruyemyy superconductor 7, passing through the additional twisting device, covers the roller 5. Twisting device 4 kinematically connected through the transmission 8 with torsion frame 3 and the actuator 9.

The device works as foreseen about its longitudinal axis with a given step of twist l. Thus the value of the step twist l at site And will be equal to

l = , where Vl- the linear speed of the superconductor; n is the number of revolutions of the twisting frame 2; n1the number of turns of the additional twisting device. The minus sign refers to the case of counter-rotation frame and additional twisting device, the plus sign is when they are rotating in the same direction. Obviously, l for n1= 0 will be equal . So, for a counter-rotation at the site A:

l = -

With a fair rotation:

l = +

At site B (i.e., the final step of twist) for a counter-movement:

l = - + =

When passing movement:

l = + - =

The above is quite obvious correlation suggests that for a counter-rotation of the torsion frame 2 and additional twisting device 4 on the site And we have a pitch of twist of less than a given step of twist l, and the area B is increased by the amount , i.e., ultimately, the step of twist l, no matter you rotate or no additional twisting device remains equal .

Thus, using a simple design for additional torsional device allows testirovanie with an additional twist when atragene as in the superconducting fibers, and in the matrix. This is achieved by simplifying the design and improving the reliability. Increased reliability is achieved primarily by eliminating the need to use a tracking system to control the drive of an external frame.

DEVICE FOR TESTIROVANIE SUPERCONDUCTOR containing attatches torsion frame with the actuator and the receiver, characterized in that it is provided located between the torsion frame and receiver and kinematically connected to the drive device, made in the form of a roller, mounted in a rotating sleeve with a direction of rotation opposite to the rotation of the twisting frame.
