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

FIELD: machine building.

SUBSTANCE: gear wheel includes body (1), gear rim with teeth (2) having working side (3) and non-working side (4) surfaces adjacent to the body by means of transient fillets (5). Profile of working side surface (3) of each tooth is identical to design one for that wheel. Profile of non-working side surface (4) represents a plane attaching the top of the tooth to its base so that transient fillet (5) is maintained. In order to avoid unauthorised reverse of the wheel, the latter is equipped with a ratchet mechanism fixed relative to the wheel so that it is possible for pawl (8) of that mechanism to be adjoined to non-working surfaces of the teeth.

EFFECT: invention allows optimising the design of the gear wheel, reducing its material consumption and costs for its manufacture.
