Calculation of Speed Ratio of Two-stage Helical Gear Reducer for Minimum Mass

摘要

This paper analyses distribution of the total speed ratio of two-stage helical gear reducer. On the minimum mass and contact strength condition, the optimum speed ratio equation is derived. By means of the least square method, the fitting formula of calculating optimum speed ratio on minimum mass candition is obtained. Using this formula, the optimum speed ratio of two-stage helical gear reducer having minimum mass can be found quickly and accurately.
