Abstract
OPTIMIZATION OF THE MASSES OF GEARS MECHANICAL TRANSMISSION DURING THE PRELIMINARY DESIGN Romaniuk O.D. Abstract Stabilization of kinematic and dynamic characteristics of the machine set in the mode of steady motion, as a rule, carried out the increase in the reduced moment of inertia, ie the use of of the flywheel. But the use of of the flywheel increases the acceleration time and weight, but also reduces the productivity of the machine set. Therefore, to eliminate the respective disadvantages of additional masses is necessary to change the approach to the design of mechanical gears. The essence of this work is that it is necessary to analyze the main parameters according to mechanical transmission with a view to their optimization in the preliminary design stage to select gear mass, which acts as a of the flywheel. The corresponding analysis was performed according to the equations to determine the mass of gears based on the entered weight ratio. As a result, graphic dependences of mass ratio of gears and gear mechanical transmission weight were obtained. Data on the dependence provide an opportunity depending on the design phase to optimize the ratio of the width of the crown gear on the center distance and the normal engagement module. Since these parameters determine the geometrical dimensions of the gears and thus reach the desired amount of weight. The resulting dependence and research results provide, at the design stage mechanical transmission, to pick up some mass moments of inertia of the gears which correspond to the time of of the flywheel swinging executive body of the machine set. The use of this approach in the design will stabilize the dynamic characteristics of the executive body of the machine without installing of the flywheel. References [1] Gemintern V.N., Kogan B.M.
