SHAFT FLEXIBLE COUPLING Russian patent published in 2006 - IPC F16D3/56 F16D3/74 

FIELD: mechanical engineering; torque transmitting devices.

SUBSTANCE: proposed flexible coupling contains alternately secured by number of flexible plates through coupling washers, bolts and nuts over circumference of flanges. One of flanges is made integral with hub provided with conical hole. Flange made integral with hub is displaced relative to place of its change over into hub in direction along axis of rotation of coupling and forms with hub a flexible ring belt. Width B of ring belt and its radial thickness R-r in place where belt changes over into hub is described by relationship B=(0.75...1.75)π(R-r) where π=3.14, R, r are maximum and minimum radial of ring belt in place of flange changing over into hub.

EFFECT: improved reliability and increased service life of coupling.
