SPINNER Russian patent published in 2011 - IPC D06F49/06 

FIELD: textile, paper.

SUBSTANCE: spinner comprising external cylindrical drum, inside of which there is a coaxial installed internal drum with the possibility of axial rotation, drive, bearing units, suspensions, cover, has a balancing device, comprising friction disk, diametre of which is less than the diametre of internal drum bottom by value that equals M, fixed on shaft of drive rotation with the possibility of friction contact with bottom of internal drum, from correcting facilities, including at least three axes, which are rigidly installed by one end perpendicularly to external surface of friction disk and are equidistant from each other. Besides, each of axes is located at identical distance from centre of friction disk, a correction disk is fixed on each of axes with the possibility of rotation, on each correction disk there is an axis rigidly installed perpendicularly to its surface eccentrically at distance π from axis of its rotation, and a roller is fixed on it with the possibility of rotation, which in contact with cylindrical surface of internal drum shell, protruding beyond its bottom vertically downwards, exerts pressure at it, from balancing disk, installed coaxially relative to axis of drive rotation with gap α relative to correcting disks and rigidly fixed to back wall of internal drum, it has fixing elements to prevent vertical displacement of internal drum upwards.

EFFECT: improved operational characteristics of spinner due to reduced dynamic loads that occur as a result of imbalance.
