With the development of high efficiency in the machinery industry, the importance of reducers as key transmission components has become increasingly prominent. Aiming at problems such as unbalanced strength of key parts and poor parameter adjustment flexibility in traditional reducer design, this study proposes a strength optimization and assembly technology improvement plan for key parts of the reducer based on parametric design. The outcomes revealed that compared with the unmodified control group, the transmission error of experimental group B (moderate modification) was 25.8%-32.4% lower than that of the control group under the working condition of 1500r/min+150N·m, and the noise fluctuation range was only 0.1dB. In the 800h continuous operation experiment, the contact stress under the 500r/min and 1000r/min operating conditions was reduced by 3.6% and 4.8% respectively compared with the control group. In the 1050h environmental adaptability test, the meshing stiffness drop of the optimized design was 2%-5% lower than that of the traditional design, and the increase in transmission error was significantly smaller. In summary, the method proposed in this study not only improves the design efficiency and performance of the reducer, but also reduces the production cost, which has important application value.
