GEAR WHEEL Russian patent published in 2013 - IPC F16H55/08 F16H55/17 

FIELD: machine building.

SUBSTANCE: gear wheel consists of body (1) and gear rim with teeth (2) including top (3), base (4), working side (5) and non-working side (6) surfaces adjacent to the body by means of transient fillets (7). Profile of working side surface (5) of each tooth is identical to design one for teeth of that wheel. Profile of non-working side surface (6) represents a plane attaching the top of the tooth to its base so that transient fillet (7) is maintained. In order to avoid jamming of teeth of adjacent wheels at unauthorised transmission reverse, the non-working side surface of each tooth is equipped with strip (8) supplementing the profile of that surface till the profile of the working side surface. Strips are made from noncritical material and rigidly fixed on surfaces after final processing of teeth.

EFFECT: invention allows optimising the design of gear wheels of nonreversible transmissions and reducing costs for their manufacture.
