Description

 . one..

The invention relates to the textile industry and can be used on ring spinning and twisting machines.

The purpose of the invention is to increase reliability and simplify the design.

The drawing shows a ring-twisting device, a slit.

The ring twisting device comprises a ring G with a slider 2, a spindle 3 mounted coaxially 3 with an annular support 4 on the side surface 5 in the housing 7 fixed to the holder 6 with a gap relative to it and with the possibility of relative rotation under tension of the thread 8.

The device has a permanently mounted annular permanent magnet coaxially with the ring with pole tips 10–13 to create a non-uniform magnetic field placed with the support 4 parts of the ring and forming a gap filled with a magnetic fluid 14 with it, Tips 10 and 12 with the ends of the magnet 9, and the tips 11 and 13 are installed in a non-magnetic frame 15, made detachable.

The device works as follows.

Permanent magnet 9 generates clocks through the pole tips.

magnetic flux 16. The geometries of the inner surfaces of the pole pieces create an uneven magnetic field in the zone of the supporting part of the ring. The magnetic fluid under the action of the created magnetic field is held in the gap between the inner surfaces of the pole pieces and the surfaces of the reference

parts of the ring. In this case, the magnetic

the liquid, which seeks to fill the parts of the gap, where the magnetic field is strongest, exerts a pressure on the part of the ring, due to which

it is in a suspended state and centered in the axial to the radial directions, both in statics and at any frequency of its rotation.

When the spindle 3 rotates due to the friction forces between the slider 2 and the ring, the latter rotates.

The lack of contact of the bearing part of the ring with the elements of the case on the holder helps to reduce its friction and thereby increase the reliability of the device. This device provides a lightweight mode of acceleration of the slider and the ring to the nominal rotational frequency and has a simple design due to the exclusion of means for forcibly supplying lubricant to the supporting part of the ring .;
