Abstract
This paper is devoted to the analysis and design of the winist. The winch uses three-phase alternating current as the power source, the voltage is 380 / 220V, and the motor realizes one-way operation. Its rope traction force reaches 12 kN, with a traction speed of 0.3 m/s, and a drum diameter of 470 mm. The paper first summarizes the application background, development status and the overall industry knowledge of the assembly design, which provides theoretical support for the subsequent research. Then, through the comparative analysis of different transmission schemes, the optimal overall design scheme is determined. On this basis, a detailed design calculation, selection and check analysis of the key parts of the winch are conducted to ensure that the performance of each component meets the design requirements. Finally, the 3 D modeling of key components using Pro / E software provides accurate model data for subsequent processing and fabrication. This study not only enriches the design theory of the winch, but also provides a useful reference for the practical application in related industries.
