| Roller movable teeth reducer, which is used to transmit rotary motion and power between two shafts with same axis, is a new type of small teeth difference planetary gear reducer. With a vast application vista, it has many advantages such as close structure, large range transmission ratio, strong load capacity and high transmission efficiency. Virtual prototyping, as a kind of brand-new products development approach, compares with traditional design method, it can not only revise and design conveniently through virtual prototype before making physics prototype actually, shorten products development period, lower costs, and can also improve the properties of product, strengthen the market competitiveness, accelerate the transformation from new technology to new products. It is very important meaning of using virtual prototyping to carry on the systematic design and performance emulation in Roller movable teeth reducer and seeking optimization design of the products.On the basis of theoretical research of roller movable tooth drive and through Pro/E and ADAMS software, this paper have established virtual prototype model of roller movable tooth reducer, realized virtual assembly, and completed the work of systematic emulation. Content of studying in this paper includes mainly in the following: 1) Based on gear engagement principle, it analyzed work principle, characteristic and transmission ratio of roller movable tooth drive, calculated gear profile of internal gear of roller movable teeth reducer profile of ring gear, and testified which provide theory base for the further modifying the profile; 2) It established virtual prototype model of roller movable tooth reducer, completed virtual design and assembly, and realized variable design. 3) Pilot discussed the model data conversion between Pro/E and ADAMS software, the paper succeeded in finishing the conversion geometry model between the two kinds of software. 4) Through having carried on dynamics imitate of roller movable teeth reducer prototype model, the paper probed into key load situation and sport characteristic that key part bear and analyzed different impacts on systematic dynamics performance of operating mode, which offered the important basis for system optimization, vibration, analysis of the life-span of noise in the future.5) Compairing the test and analyses of roller movable tooth drive and swing movable tooth drive which have same size and structure through dynamics imitating, superiorities and shortcomings on design, property and manufacturing of these two kinds of movable tooth drive can be achieved, that would be useful to their theoretical research and applications. |
