In the process of geometric optimization of the gear reducers, an important role is played by the decrease of the housing weight. The optimization of housing should include stress state analysis, as well as modal analysis. This paper focuses on the modal analysis of the housing from a two-stage cylindrical reducer transformed into a one-stage reducer. The frequencies are obtained using finite element analysis and experimental modal analysis, highlighting the good correlation between the results. Also, the differences between the first six vibration modes of the original housing in relation to the first six vibration modes of a modified housing (without the intermediate frame designed for the two-stage reducer) are analyzed. In the last part of the paper were discussed, based on the mass participation factors, the displacement trends for each mode of vibration.
