GEAR WHEEL Russian patent published in 2014 - IPC F16H55/12 

FIELD: machine building.

SUBSTANCE: gear wheel includes body, gear rim and a pair of ring pads fixed on the body and covering teeth edges. Gear rim is made of separate teeth not connected to each other. Each tooth is fixed on an axis fixed between pads so that it can be turned in both sides in the wheel rotation plane. Between the tooth base and the wheel body a clearance is provisioned. The tooth base along all over its width has a rectangular protuberance. The protuberance is recessed in the wheel body, for this purpose the latter has a companion recess with clearances with reference to the surface of the recessed protuberance. On the wheel body on the section of the projection of the tooth base a flat site is made, and from each lateral side of the tooth between its base and body and lateral side of the protuberance and the body an angular elastic insert is placed.

EFFECT: shock strength of teeth gear wheels is increased.
