Research On The Technology Of Gear Automatic Transmission Line And Its Chain Transmission System

Automatic gear conveyor lines are mainly used in the field of gear production and processing transfer.With the continuous improvement of industrial manufacturing level,gears as the most widely used basic parts in industrial production related to the production and processing requirements have become more and more strict.Gear automatic transmission line as a gear production and processing process transmission device because of its high transmission accuracy,less manual operation,It could be applied to harsh working environment,which could effectively improve the precision and efficiency of gear production.It would be the key point for the development of the future gear production industry.The chain conveyor system is an significant component of an automatic conveyor line,it is not only the transmission force of the body is also the gear object bearing parts are often subject to changes in dynamic load and large impact,The relevant performance of automatic conveyor lines is closely related to their dynamic characteristics.It is therefore important to explore the technical characteristics of geared automatic conveyor lines and their chain conveyors.In this article,according to project requirements and production conditions,the structural design of the automatic conveyor lines is completed by selecting key institutions.SolidWorks is used to draw entities and fit machine structures together,then the key parts of the follower roller are simulated and analyzed statically.According to the viscoelastic attributes of chain conveyor system,the relevant model is established by using Kelvin-Voigt structure.After determining the simulation parameters of the chain conveying system,The chain conveyor system is created using Matlab/Simulink,then conclusions were drawn from experimental analyses performed under different conditions,and finally a GUI user interface is developed.Finite element analysis of the system.Based on the previous test results,the main components of the link unit are analyzed at the moment of chain jam under different conditions,and then the conventional modal analysis of the chain conveyor system is compared with the pre-stressed modal analysis to obtain the results of the inherent frequency and vibration pattern of the system at each order.Then the harmonic response analysis and transient dynamics analysis are carried out,and the corresponding conclusions are obtained.The position control of chain conveying system based on variable domain fuzzy PID technology is studied.Creating a position control model based on the triple closed-loop control principle and derive the position loop function for this model.The conventional PID controller,fuzzy PID controller,and variable-domain fuzzy PID controller are built in Matlab/Simulink and simulated using the same signal for comparison tests.Definitely the use of variable domain fuzzy PID technique can effectively improve the relevant characteristic index of position control model and thus have a better control effect.
