Science and Innovation| Summary: | Introduction. The stabilization of kinematic and dynamic characteristics in machine assemblies, which exhibitperiodic changes during steady-state operation, has necessitated the development of methods for optimizing flywheel masses to enhance the productivity of machine executive bodies.Problem Statement. Stabilizing the parameters of machine assemblies with additional flywheel masses increases the overall weight and inertia of the mechanism. Therefore, it has become essential to design mechanicaltransmissions with optimized rotating assembly masses that can perform the function of flywheel masses.Purpose. This study has aimed to develop a method for estimating the mass of a rotary assembly in a mechanical transmission during the preliminary design stage, utilizing the power parameters of the machine unit.Materials and Methods. Analytical approaches have been employed to study the dependencies in a machineunit model and its rotary assembly, featuring cylindrical gears.Results. A functional dependence of the rotary assembly mass on torque, gear ratio, and the mechanical characteristics of gear wheel and shaft materials has been established. Mass coefficients for gears and shafts havebeen derived, allowing variation through material selection and heat treatment. This expands the range of optimization options and simplifies solving multivariate design problems.Conclusions. The proposed method for estimating the rotary assembly mass at the preliminary design stage,based on the machine unit’s power parameters, has shown promise. It provides a clear framework for aligning themasses of assembly components with the required flywheel moment, ensuring stabilization of the machine unit’skinematic and dynamic characteristics. |
