FIELD: machine building.

SUBSTANCE: gear wheel includes body, gear rim with teeth and a pair of ring pads fixed on the body and covering teeth edges. Gear rim is made of separate teeth that are not connected to each other.

The tooth base has a rectangular protuberance depressed in the wheel body. The wheel body has a companion recess with a possibility of protuberance movement with the tooth rotation. The protuberance plane located opposite to the lateral side of a tooth, exposed to shock loads, adjoins to a companion plane of the recess, and between an opposite plane of the protuberance and companion plane of the recess the elastic element is located.
