Based on the conventional cycloid gear force analysis , a force analysis theory which can apply to new - style three - disk - cycloid - driving was produced and an accurate force analysis mathematics model of the new - style drive was established . the cad software of force analysis was programmed and the precise age limit of arm bearing was calculated . based on the existing theoretical research , sfa45 - 59 conventional type three - disk - cycloid - reducer was designed and its main parameters were determined 基于传统的针摆行星传动受力分析，提出了适用于三片摆线轮新型针摆传动系列的受力分析理论，并建立了三片摆线轮新型针摆传动系列力分析的数学模型，编写了受力分析的cad软件，同时对转臂轴承的寿命进行了精确的计算。
