WASHING-WRINGING MACHINE Russian patent published in 2011 - IPC D06F23/02 D06F37/22 

FIELD: textile, paper.

SUBSTANCE: washing-wringing machine comprises an external drum, an internal drum, hanger brackets, a balancing device, a support device, consisting of an upper ring rigidly fixed on the outer surface of the internal drum shell, and a lower ring connected to the upper ring by means of fastening elements. The balancing device comprises a balancing disc installed coaxially to the axis of the drive rotation and rigidly fixed to the back wall of the external drum, a friction disc, rigidly installed on the drive shaft, and correction facilities, comprising at least three axes, which are installed perpendicularly to the external surface of the friction disc, are equidistant from each other and from the centre of the friction disc. A correction disc is fixed on each of axes with the possibility of rotation, on which an axis is rigidly installed perpendicularly to its surface. A roller is fixed on axis with the possibility of rotation, which, when in contact with the inner surface of the upper support ring, presses against it. The balancing device has elements to retain the bottom of the internal drum and the friction disc in condition of a friction contact, and they are bushes with flanges and springs. Each bushing is fixed on a free end of each of three axes and with its flange it is installed with the possibility of friction contact on the lower ring of the support device.

EFFECT: improved operational characteristics of a washing-wringing machine due to reduced dynamic loads that occur as a result of imbalance.
