Research On The Press-mounting Process Of Gearbox Assembly

The gearbox assembly processes include many press-mounting processes such as gearbox inner spindle parts and the sleeve parts. The proper selection of the press-mounting process affects the performance of the gearbox directly. The appropriate Gearbox press-mounting process need press-mounting machine with the function of monitoring press-mounting force-displacement accurately. To achieve this function, this paper will aim to the press-mounting process of the gearbox assembly, by theoretical calculation, the finite element simulation, actual press-mounting date to make research and analysis, develop the press-mounting equipment.First of all, this paper elaborates on the structure and the work principle and press-mounting process of gearbox. Then made comparison and research on various press-mounting methods in details, and choose AC servo press-mounting method as the best press-mounting method that can meet the requirement of gearbox press-mounting process.By the finite element method, deduce the assembly Process that press gearbox taper roller bearing to gear bearing, deduce a theoretical calculation formula, then according to the formula calculated some gearbox press-mounting parameter, draw the press-mounting force—displacement curve. By using ANSYS, to do a model building analysis on above-mentioned press-mounting process. First, made model building analysis on each gearbox press-mounting part, get the press-mounting parameter, put out the press-mounting force—displacement curve; Second, change each theoretical formula parameter of the analytical model, draw the chart of the relationship between press-mounting force and parameter respectively, to verify the accuracy of the theoretical calculation formula. Through theoretical calculation and the software simulation, to get the initial press-mounting parameter of each press-mounting part, provide the theoretical basis for the next design of the press-mounting equipment, in order to meet the requirement of the press-mounting process better.Choose the proper electric servo cylinder, draw the control flow chart, as the core component of press machine, and input above-mentioned press-mounting parameter, next conduct the press-mounting experiment. Then according to the result of press-mounting force-displacement from the press-mounting experiment, and draw the curve, made a comparison of calculated-simulated-actual between the curve and the theoretical curve and the software output curve, to verify the applicability of theoretical calculation and software simulation during actual assembly process of the project, the result of press-mounting be able to meet the requirement of the press-mounting process.
