FLUID COUPLING Russian patent published in 2009 - IPC F16D33/08 F16H41/22 F16H39/00 

FIELD: mechanics.

SUBSTANCE: fluid coupling comprises a pump rotor made up of impeller with mid cylindrical part and inner and outer casings, half-coupling with flange tightly fitted on the engine shaft, turbine rotor incorporating a moving rotor fitted on the shaft and header accommodating a scoop pipe. The pump rotor is fitted on the engine shaft and incorporates an additional bearing support, while the two-support turbine engine runs in bearings and incorporates the pump rotor additional support bearing seat. The turbine rotor seats on bearings fitted of the engine shaft or half-coupling. Hollow turbine shaft features the length not exceeding the axial size of as-assembled pimp impeller and moving rotor and the distance between end faces of the engine and driven machine. Afore mentioned header is arranged on the driven machine immobile housing. The pump rotor additional bearing support is fitted in the impeller disk hub. The proposed fluid coupling incorporates additionally the second fixed scoop pipe. The annular header locks the mechanical coupling toothed casing, while the fluid to lube and cool inner thrust bearings is forced through the hollow shaft inner surfaces.

EFFECT: torque adjustment with no turbine rotor outer support, reliability and smaller sizes of rotor and fluid coupling proper.
