Abstract

The invention relates to an optimization design method for a high-power-density 2K-H planetary gear train. The 2K-H planetary gear train comprises a sun gear, n planetary gears and an inner gear. The method comprises the following steps of according to known variables and design variables, calculating a tooth number of each planetary gear; calculating a tooth number of the inner gear; calculating the volume of the sun gear; calculating the volume of each planetary gear; calculating the volume of the inner gear; calculating transmission efficiency of the sun gear and the planetary gears in a change gear train; calculating transmission efficiency of the planetary gears and the inner gear in the change gear train; calculating the volume of the 2K-H planetary gear train; calculating transmission efficiency of the 2K-H planetary gear train; and by taking minimum volume of the 2K-H planetary gear train and minimum transmission efficiency loss of the 2K-H planetary gear train as optimization objective functions, performing optimization iteration, thereby finishing the design of the high-power-density 2K-H planetary gear train. According to the method, the volume of the 2K-H planetary gear train can be reduced and the transmission efficiency of the 2K-H planetary gear train can be improved.

Description

technical field [0001] The invention relates to a design method of a planetary gear train, in particular to an optimal design method of a high power density 2K-H type planetary gear train. Background technique [0002] High power density design has become an important development direction of transmission system design. The 2K-H planetary gear train, as the transmission system between the prime mover and the working machine, has been widely used in the fields of machine tools, automobiles and ships. [0003] At present, the design method of the 2K-H planetary gear train mainly considers the strength performance of the gear. There is still no method at home and abroad that considers both the transmission efficiency of the 2K-H planetary gear train and the 2K-H planetary gear under the premise of satisfying the gear strength performance. High power density optimization design method for gear train volume. Contents of the invention [0004] The technical problem to be solve...
