Research on the Transmission Efficiency Improvement Method of Reducer Based on Gear Parameter Optimization
Taking a first-grade reducer as an example,this paper optimizes the parameters of small gear shaft and large gear shaft,establishes the objective function and constraints by determining the parameter ranges of gear ratio,module,tooth width,pressure angle,helix angle,addendum coefficient and clearance coefficient,and opti-mizes them by using genetic algorithm.The optimization results show that the transmission efficiency of the reducer is increased from 98.4%to 99.0%,and the gear meshing power loss is reduced from 127.5 W to 100 W,which veri-fies the effectiveness and practicality of the gear parameter optimization method.
