【摘要】 滚柱活齿减速器是一种用于传递两同轴间回转运动的新型少齿差行星齿轮减速器,具有结构紧凑、传动比范围大、承载能力强和传动效率高等优点,应用前景广阔。虚拟样机技术作为一种崭新的产品开发方法,同传统的设计方法相比,它不仅可以在实际制造物理样机之前通过虚拟样机来方便地修改设计,缩短产品开发周期,降低成本,而且还可以提高产品性能,增强市场竞争力,加速新技术向新产品的转化。应用虚拟样机技术对滚柱活齿减速器进行系统设计和性能仿真,具有十分重要的意义。本文在滚柱活齿传动理论研究的基础上,利用Pro/E和ADAMS软件,对滚柱活齿减速器进行虚拟样机建模和性能仿真,实现了虚拟设计、装配和系统仿真研究。本论文研究的内容主要包括:1)基于齿轮啮合原理,对滚柱活齿传动的工作原理、特点和传动比进行分析,对中心轮齿形进行综合正解,为进一步进行齿廓修形提供了理论基础;2)建立了滚柱活齿减速器虚拟样机模型,完成了虚拟设计和装配;3)完成了Pro/E和ADAMS之间接口文件的安装,成功转换了两者之间的几何模型;4)通过对滚柱活齿传动样机模型进行动力学仿真,探讨了关键部件运动特征及承受的载荷情况,分析了不同工况对系统动力学性能的影响,为今后系统优化及振动、噪声和寿命的分析提供了重要的依据;5)通过仿真对比试验、分析了相同尺寸和结构下滚柱活齿传动和摆动活齿传动两种减速器样机的不同输出和受力情况,并比较了两类活齿传动在设计、性能和制造等方面各自具有的优缺点,为推广活齿的理论发展和实际应用奠定了一定的基础。更多还原

【Abstract】 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.更多还原
