TOOTH-WHEEL Russian patent published in 2015 - IPC F16H55/17 

FIELD: machine building.

SUBSTANCE: tooth-wheel contains rim with toothing, hub carrying diaphragm, rigidly connected with rim and hub, and dampening element made in form of tab plate disk, installed between the hub and rim and secured by internal part on the external surface of hub, and by external part of tabs interacting with the internal surface of the rim. External part of each tab of the plate disk has toroidal shoulders, located concentrically one relatively another with possibility if interaction with the internal surface of the rim made conical. The internal part of the plate disk is secured on the external surface of the hub using the regulated stop, at that ratio of dimensions of plate disk, toroidal shoulders and internal cone surface of the rim are selected on the condition to ensure maximum operation force of dry friction between the surface of shoulders and internal cone surface of the rim under mode of resonant oscillations of the tooth-wheel rim.

EFFECT: reduced amplitude of resonant oscillations of the rim by 50 times, thus significantly increasing operation reliability and durability of the tooth-wheel.
