FIELD: physics.
SUBSTANCE: cog-wheel system includes a cog-wheel and a toothed wheel, coaxially placed relative a rotating shaft, and a fastening device between said cog-wheel and said toothed wheel to prevent relative displacement of one of them relative each other. According to the invention, the fastening device has a profiled depression, the shape of which at least partially matches the cross-section of said section and which is made on the hub of said wheel for fastening said cog-wheel and toothed wheel for rotation.
EFFECT: preventing sheer stress.
