KASHIGIN ECCENTRIC CONNECTION Russian patent published in 2016 - IPC F16B2/18 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, to detachable connections which transmit torque, and can be used in primarily in structures of devices, machines, instruments and equipment. Torque transfer is carried out by eccentricity e of thickened portion of part, which increases strength and reliability of connection. Between interacting cylindrical eccentric surfaces of mating parts there is a 0.05-0.20 mm gap, between female and male parts there can be a bushing whose axis is aligned with that of eccentric centering cylindrical surface of male part, and bushing is made of non-metal material with high friction properties.

EFFECT: substance of invention consists in connecting centering and eccentric surfaces of one of parts of a connection into a single surface - centering eccentric cylindrical surface, which twice reduces linear dimensions of connection, completely eliminates its jamming, reduces requirements for accuracy of fabrication, simplifies assembly-disassembly of connection, etc.
