The paper present the problem of permanent fixing of the axisymmetric elements relative position on the example of pulley mounting on the shaft. A method of permanent and quick fixing of pulleys on shafts has been sought for years. A number of detachable and inseparable joint solutions are available. The authors are looking for an inseparable solution allowing for quick assembly in serial production conditions. The quality of this connection is important for the geometry of the transmission gear, as it has a significant impact on the quality of the transmission gear operation and the belt life.
