ELASTO-DAMPENING CLUTCH Russian patent published in 2011 - IPC F16D3/52 F16H25/20 

FIELD: machine building.

SUBSTANCE: elasto-dampening clutch consists of driving shaft, driven shaft and intermediate bush. The driving shaft is connected with an intermediate bush by means of screw splines. On external surface of the intermediate bush there are cut screw splines of counter direction engaged with internal screw splines of the driven shaft. An elastic element is installed between the intermediate bush and the flange of the driving shaft via an anti-friction washer. Also, tilt angle of a screw line of splines amounts to φ_fr≤ψ≤ (90°-φ_fr), where φ_fr - is friction angle.

EFFECT: increased angle of twist of driving shaft relative to driven one and increased power output of clutch.
