Abstract
The rotating systems of machines, such as the power transmission of the centrifugal washing machine, are exposed to vibrations that can cause failures during their operation due to their rotating elements and variable loads. With the aim of improving the design of the gear train of a centrifugal washing machine, it is proposed to perform a topological optimization to reduce the vibration and to propose a measurement system to determine the vibrations of the gear train. The ANSYS Student software is used to study the behavior of the power transmission system and optimize the topology. Topology optimization is performed for two types of gear (helical and hypoid), which must be the largest in order not to affect the design factors in the gears. The measurement system is raised through the analysis of the set of gear train components (shafts and gears), using the frequency response analysis in the shaft sections where the bearings are located. From the optimization it was obtained that the maximization of the natural frequency and the reduction of the magnitude of the accelerations of the frequency response in the power transmission system is reflected when applying the mass reduction in the helical gear, also that the gears of bevel types must pose multiple response restrictions since these are part of the objective of optimization, and not only based on the reduction of mass.
