POWDER CLUTCH COUPLING WITH CONTROL DRIVE Russian patent published in 2013 - IPC F16D37/02 

FIELD: machine building.

SUBSTANCE: powder clutch coupling with a control drive includes a detachable housing with coaxially installed shafts, on which drive and driven discs of half-couplings are rigidly fixed. On end faces of the discs there are several conical grooves and projections located concentrically, which interact with each other. End surfaces of both discs are broken into several sectors with radial cavities. The driven disc sleeve is provided with a constant magnet made in the form of a ring-shaped disc. The drive disc sleeve is provided with an electromagnet winding, the leadouts of which are taken beyond the limits of the housing through the channels made in the drive shaft body connected to slip rings installed on the output end of the drive shaft, and closed with a cover plate that is attached to the housing wall by bolts. Slip rings are insulated from the shaft with an insulation bushing and interact with slip brushes that are connected by means of two conductors to contacts of a bipolar switch. Opposite contacts of the switch are connected to terminals of a direct current source. An adjustable resistor is connected to one of the chains.

EFFECT: enhanced engagement reliability.
