Spur gear transmission is the most important transmission mode in mechanical equipment. It has the advantages of high transmission efficiency, compact structure and stable transmission. Its performance directly affects the performance level of mechanical equipment. With the development of science and technology and productivity, the requirements of high speed, high efficiency, high strength, miniaturization, long life and low noise are put forward for the transmission performance of spur cylindrical gear mechanism and spur cylindrical gear. In order to meet these requirements, we must deeply study the dynamic characteristics of spur cylindrical gear whistle, Test and analyze the transmission performance of spur gear, improve the design and manufacturing level of spur gear and the performance of mechanical products, and further solve the three-dimensional visual graphics, modeling and Simulation in the virtual design and manufacturing technology of spur gear products Dynamic design, analysis and calculation and other modern design technical problems.
Involute spur gear transmission is the most widely used spur gear transmission. It has large transmission speed and power range, high transmission efficiency, a pair of spur gears can reach, high precision and easy lubrication; Small sensitivity to center distance, convenient assembly and maintenance; It can carry out displacement cutting and various shape and edge modification to improve the transmission quality; Easy for precision machining; It can be widely used in light industry, chemical industry, mining, automobile and building materials machinery.
Spur gear has the basic characteristics of all other spur gears. The research on its dynamic design technology and simulation technology has certain theoretical value and engineering significance.
Aiming at the static and dynamic meshing problems of spur gears, the dynamic and static meshing characteristics of spur gears are analyzed by and software. With the combination of self-made spur gear transmission test-bed and advanced virtual instrument software platform I, the dynamic collection and analysis of tooth root bending strain data in the spray process of spur gear are carried out. The bending stress and strain in the tooth root sensitive area simulated and tested in this paper can provide key data for the reverse calculation of tooth surface friction coefficient. It is an important basis for the quantitative calculation of tooth surface friction and the simulation and optimization of tooth surface friction process.
