| Abstract: | In thepaper, a new type the elastic sliding key gearshift mechanism of machine tools waspresented, and the gearshift mechanism structure principle is analyzed. It is explainedthat the forces acting on the elastic sliding key, the calculated stability and bouncingtimes. It builds up simple models to analyze stability and vibration system. The propersliding condition and losing stability critical pressure of mathematical formula is to befound. Based on this theory, elastic sliding key gearshift mechanism of machine tools canbe designed. |
