SUBSTANTIATION OF BASIS PARAMETERS OF THE DETALS NEW STRUCTURE OF CONNECTION OF CHANGING HARDNESS

English abstract

The substantiation of the main parameters of the details of the new structure of connection of changing hardness. The rational parameters of the details are defined in depending on the size of the load, materials, technological and operational conditions. Application of changing hardness in cars will allow to increase reliability and reliability the comfort of transports, and vibration machines – vibration resistance. It is recommended to use this design of the connection of changing hardness in vehicles operated in difficult conditions (offroad driving – construction, land reclamation and mining machines). The article deals with the detailed description of the structure and the principle of the new design of the connection. Method of calculation on the strength of the details is carried out in stages: we install the power the ratio between the details; determine the geometric characteristics of the sections; we calculate the stresses in the characteristic cross-sections; we draw a conclusion about the strength of the details. Analysis of the connection shows that the transfer of motion from the shaft to the sleeves occurs in the case of compression, so in the thread and on the supporting surfaces of the sleeve, the forces of resistance are due to the friction between the movable by the parts of the parts and the elastic forces of the sleeve. Installed dependencies for determining moments of driving forces, moments in the thread and friction on the supporting surfaces of the parts. The axial force that provides the transmission of the torque between the connection is determined. Considered the redistribution of torque between the connection details: sleeves-tubes, based on the assumption that the angles of twisting of the named parts at the point are the same. The geometric characteristic of the section of the bushing is calculated: the moment of inertia relative to the main axis. Defined internal forces in cross-section and maximum stresses and, on the basis of comparison of them with permissible, made a conclusion about the strength of the details. In the list of references you can find information about others types of new structures of connections of changing hardness (structure, principle of work, methods of calculations).
