A Search Method of NN Reducer’s Transmission Ratio
The transmission ratio of NN reducer is discrete and nonlinear, and the gear matching method determines the volume and stability of a reducer. In previous studies, most scholars tried to find out the key parameters affecting the change of transmission ratio or the change rule of transmission ratio. However, the search method is complicated and tooth matching method is single. An improved differential evolution algorithm is proposed to search the transmission ratio. The constraint variables of the teeth in the transmission ratio are analyzed, and the global search of the transmission ratio and the matching method within the specified range is carried out by using the four-fold cyclic logic. An adaptive differential evolution algorithm is improved, and the forced intervention differential evolution algorithm based on the change of the optimal trait is proposed, which adjusts the mutation operator timely based on the change process of the optimal trait in each evolutionary period. Taking the solution of the maximum transmission ratio as an example and based on the global search results, the possibility of using differential evolution algorithm to solve the transmission ratio problem of NN reducer is verified.
