Abstract:

Purpose. To define the rigidity of tooth gearings, shaft, and couplings connected in one kinematic sequence in ball mill drive.

Methodology. The important stage of preparation of the rated diagram of electromechanical system is the definition of its parameters. The parameters of electric motors can be accepted under catalogues but instants of inertia, rigidity of transfers and other parameters are subject to calculation.

Findings. We have determined the analytical parameters allowing us to define the rigidity of gear gearings, rigidity of shaft drive and rigidity of elastic coupling, shaft drive of drums of spherical mills connecting the ends.

Originality. To determine the rigidity of constructive elements involved into the rated diagram of electromechanical system of the drive of spherical mill, we have chosen the rated dynamic model executed in the form of two-mass electromechanical system which contains two concentrated inertial weights connected by one elastic viscous connection of the engine rotor and working body of the machine.

Practical Value. Gear gearings of the spherical mill and the operating forces deforming teeth and connecting elastic deformations have been considered. The offered procedure allows defining the rigidity of the elements entering a kinematic circuit of any electromechanical systems of drives and choosing their design data in the future.
