Design And Transmission Performance Analysis Of Rubber Alloy Filtering Gear Reducer

With the rapid development of aviation, aerospace, shipbuilding, automobile, equipment manufacturing etc., the traditional reducers in certain industries has been unable to meet some requirements, such as small volume, large load, high precision, high efficiency, high reliability etc.. According to these more prominent problems, Chongqing University Professor Wang Jiaxu invented a precise filtering driving gear reducer (patent number:ZL201010104359.5). Compared with the other gear reducer, it has the advantages of high stiffness, small volume, light weight and easy to process etc., In order to further improve the filtering gear reducer transmission performance, Wang Jiaxu Professor invented filtering gear based on rubber alloy or soft elastic material (patent No.:201110054609.3). The main contents of this paper can be summarized as follows:①Filtering gear is introduced in this paper, the structural composition and working principle of rubber alloy filtering gear reducer are briefly analyzed, according to the design requirements, the structure design of speed reducer:including the optimized allocation of the number of teeth and the calculation of geometric dimensions; checking the profile overlap interference and interference of transition curve; the eccentric value determination of eccentric shaft; structure design of rubber alloy layer.②The use of SolidWorks3D software to establish the reducer based on virtual prototype model, and virtual assembly and interference analysis. In order to determine the vibration characteristics of the speed reducer, reducer for the first ten modes are analyzed by using ANSYS finite element analysis software Workbench.③The vulcanization forming technology of ordinary rubber is analyzed in-depth and meticulously to determine the filtering gear vulcanization forming process. According to the characteristics of filtering gear and requirements of forming process, the precision forming die of filtering gear is designed.④The reasons of return difference are analyzed, based on the probability statistics method and the features of rubber alloy filtering gear reducer, rubber alloy reducer’s backlash calculation formula is deduced, compared with rubber alloy layer before and after filtering deceleration return difference, analysis of rubber alloy layer on the rubber alloy filter deceleration return difference effect,rubber alloy filtering gear reducer for rigid-flexible hybrid modeling and filtering gear reducer rigid body model are built in Adams software, comparison the results of analytical dynamics, the influence of rubber alloy layer on the rubber alloy filter reducer transmission stability is clear.⑤Rubber alloy filtering gear reducer and general filter reducer’s backlash experiment was done, contrast of the experimental results, and get the relevant conclusions. And then propose improving plans.The vibration test result of filtering gear reducer without rubber alloy layer and rubber alloy filtering gear reducer indicate that the rubber alloy filtering gear reducer has better vibration characteristics,,which can be achieved the purpose of reducing low frequency fluctation and filtering heigh frequency fluctation.
