Liu Dongmin and Xue Peijun from the School of Engineering Technology of Zhongzhou University described in "Optimized Design of High-shear Emulsification Machine Reducer in Food Machinery", starting from the goal of miniaturization and light weight of emulsification machinery products, the reduction gear transmission system is carried out. Optimizing the design, establishing an optimization model, and conducting data analysis for the optimization design, using a fuzzy optimization model to solve it. The analysis results show that through the optimized reducer, even if the outer diameter is reduced, its running performance can still meet the working requirements.
