Abstract
The design and optimization of precision mechanical transmission system is one of the core issues in the field of modern mechanical engineering, which is of vital significance to improve the performance of mechanical equipment, extend the service life and ensure high precision operation. This paper focuses on the design and optimization of precision mechanical transmission system, discusses the key elements of system design, optimization strategy and its effect in practical application. This paper describes the importance of precision mechanical transmission system and the basic principles of its design. As the core component of mechanical equipment, the performance of precision mechanical transmission system directly affects the operating accuracy and efficiency of the whole equipment. Therefore, in the design process, it is necessary to fully consider the key indicators such as precision, stiffness, strength and wear resistance of the transmission components, and follow the design principles of high transmission efficiency, low noise and low failure rate. This paper introduces the optimization strategy of precision mechanical transmission system in detail. Aiming at the problems of high energy loss, high noise and high failure rate of the traditional mechanical transmission system, this paper puts forward a variety of optimization methods, including selecting high-performance materials, optimizing the geometry and size of the transmission components, and improving the lubrication mode and conditions. In addition, the possibility of optimizing the transmission system by using modern design methods and simulation analysis techniques, such as finite element analysis and multi-body dynamics simulation, is also discussed to predict the system performance more accurately and optimize the design parameters. In the experimental research part, based on the above design principles and optimization strategy, this paper designs and manufactures a precision mechanical transmission system prototype, and carries out performance testing and verification. The experimental results show that the optimized transmission system has higher transmission accuracy, lower noise and lower failure rate, and significantly improves the overall performance of mechanical equipment. This paper summarizes the research results of precision mechanical transmission system design and optimization, and looks forward to the future development direction. With the progress of science and technology and the development of industry, the requirements for precision mechanical transmission systems will be higher and higher. Therefore, future research will pay more attention to the exploration and application of new materials, new technologies and new methods to promote the further development and innovation of precision mechanical transmission systems.
