SELF-BALANCING DEVICE OF DRUM-TYPE WASHING MACHINES Russian patent published in 2015 - IPC D06F39/00 

FIELD: machine building.

SUBSTANCE: SBD is a device combined with a washer drum installed coaxially inside a boiler, able of rotation around a horizontal axis and consisting of the outer and inner cylindrical tanks of the drum. The torque of the outer cylindrical drum tank is transferred from the motor via a drive shaft, and that of the inner cylindrical tank - via a hinge, thus providing for the synchronous rotation of the outer and inner cylindrical drum tanks, as well as for the transverse movement of the inner cylindrical drum tank, perforation zones of the outer and inner cylindrical drum tanks are matched and set opposite each other, a tight elastic tank filled with a working liquid without hollow spaces is located between the side walls of the outer and inner cylindrical drum tanks in a stationary way without gaps, except for the perforation zones.

EFFECT: availability of the tight elastic tank provides for the easier disassembly and repair of the washing machine, preventing the transmission of vibrations from the drum to the main casing.
