三环减速器内齿环板应力分析

STRESS ANALYSIS OF DRIVING RING BCARD OF THREE-RING TYPE GEAR REDUCER

三环减速器是为适应机械工程发展需要、在综合分析已有的平行轴少齿差减速器技术发展趋势的基础上开发的一种新型传动装置。内齿环板是三环减速器的关键传动零件，在该传动机构中实质是一连杆，承受一定的冲击；又是一内齿轮，是一计算分析比较复杂的零件。其强度性能直接影响整机的运动和动态性能。借助于Ｉ－ＤＥＡＳ软件对该内齿环板的应力和变形进行了数值计算，在深入分析的基础上，提出了相应的设计准则和结构改进措施。

Based on the synthetic analyses of technical development trend of Planet gear transmission reducers with parallel axis,three-ring type gear redncer is developed to adapt the development needs of mechanical engineering.Driving ring board functions both as a connecting rod and an internal gear in this type of transmission mechanism.SubJected fo impact under working conditions,it is the key transmitting component requiring detailed numerical simulation and its strength charcteristic directly affects the kinetic and dynamic properties of the new type reducer.In this paper,with the aid of IDEAS software,numerical computations of the stress and deformation of driving ring board are conducted.Based on the analyses,correspondent design norm and structional improving measures are presented.
