Reducer is an independent component composed of gear transmission, worm transmission and gear worm transmission enclosed in a rigid housing. It plays the role of matching speed and transmitting torque between prime mover and working machine or actuator. It is widely used in modern machinery. Today, this field is still the focus of scientists around the world.
A heavy-duty low-speed reducer is designed. The design idea is: first, the layout design of the transmission structure of the reducer is carried out, then the parametric design of the gear transmission system is carried out, and then the topology optimization design of the reducer box structure is carried out through the finite element analysis method. Finally, a professional app for parametric mechanical design of the gear transmission system is proposed, and its feasibility is proved through practical operation.
Through the analysis, the objective function and constraint conditions of the optimal design of the two-stage helical cylindrical gear transmission system are obtained, the design variables of the system are established, the multi-objective optimization model of the two-stage helical gear transmission is established, and the model is applied to the engineering practice to reasonably optimize the gear transmission system. The optimization results show that the design meets the requirements, saves materials and reduces manufacturing costs.
