TAPER GEAR WHEEL TOOTHED GEAR TORSION OSCILLATION DAMPER Russian patent published in 2008 - IPC F16F15/08 F16F13/00 F16F7/00 

FIELD: engines and pumps.

SUBSTANCE: damper incorporates a gear wheel with its axle resting upon bearing support made up of the housing and two bearings. The torsion oscillations (torque forces) are converted into axial forces are transmitted from the gear wheel to the housing via an axial annular flexible element. The said element contains two metal races with a flexible ring attached there between. The bearing inner races are tightened via a spacer sleeve on the gear wheel axle by the internal nut. The flexible ring is arranged inside the housing between the bearing outer race and the external nut. The nut presses the outer race with the force one and a half to two times higher than the working axial force acting on the taper gear wheel.

EFFECT: simpler design, smaller sizes, damping torsion oscillations and impact loads in high rpm gear transmission.
