As the short-distance transfer and conveying equipment of large and super-large crushing stations, Apron Feeder For Sale is mainly used for the transfer operation under the pressure condition of the feeding machine bin of the breaking system, which mainly consists of the driving device, spindle device, chain belt device, support device, tensioning device, rack, plate hopper and other parts. The drive sprocket as a key component of the plate feeder is located in the main shaft device, through the drive chain belt device will drive the rotary motion transfer into linear motion, to achieve the purpose of conveying materials.
In recent years, foreign scholars have made a lot of new research progress on Apron Feeder For Sale drive sprocket. The empirical formula of tight edge force was proposed in the literature through several groups of experiments, and the experiments showed that the dynamic load of the chain had little influence on the force of the chain joint under the low rotational speed of the sprocket, which could be considered as a quasi-static case. Based on the complete standard tooth sprocket, the static force model of the chain and sprocket in the surge area is established, and the force on the chain drive system is obtained by the Newton-Raphson numerical method.
For large Marine diesel engine chains, a multi-body dynamics model of Apron Feeder For Sale chain transmission was established for the actual sprocket tooth profile and the simplified semi-circular tooth profile. The changes of the surge contact force and tension were analyzed, and the solution results of the mathematical model were compared with the software simulation results.
In recent years, domestic scholars have carried out a series of related researches on plate feeder drive sprocket. The paper introduces the calculation method of the circumferential force of the sprocket, analyzes the relationship between the material thickness and the chain speed through the theoretical calculation, and draws the conclusion that controlling the feeding thickness has an effect on the selection and service life of the chain. Gu Rentao calculated the sprocket tight edge tension and loose edge tension method, so as to analyze the elastic deformation of the inner and outer chain joints of the timing roller chain drive, as well as the elastic deformation of the sprocket, and then modify the standard sprocket tooth profile to get a new non-standard sprocket net. The paper uses the BMX module of PRO-E software to optimize the size of sprocket, so as to get the best tooth shape of sprocket. In the literature, ANSYS software is used to carry out finite element analysis on the stress condition of the sprocket and chain, so as to find out the parts easily damaged on the sprocket, and optimize the structure size with the maximum equivalent stress value of the relevant parts as the objective function, so as to achieve the purpose of reducing the working intensity of the sprocket and extending the service life.
We simplified the force of the Apron Feeder For Sale sprocket, applied Pro/ENGINEERMechanica mechanical analysis and modal analysis of the sprocket integrated with the existing research results, the existing research is mainly aimed at the teeth of the driving sprocket, structural parameters and the relationship between the force, deformation of the study. In the above research, only the influence of a sprocket design parameter on the chain drive system is considered. Taking the heavy plate feeder of a certain type of self-moving crushing station as the research object, the external load borne by the driving sprocket during the movement of the heavy plate feeder was obtained through theoretical calculation, and the three-dimensional parametric driving model of the driving sprocket was established in the finite element analysis software, so as to achieve the optimization goal of minimizing the system mass and stress. Using the dividing circle diameter, roller outside diameter and tooth width of the drive sprocket as design variables, the structure optimization design of the sprocket was carried out with the help of multi-objective genetic algorithm.
