摘　　要：以采掘设备常用截割减速器NGW行星传动为研究对象,分析了该行星传动各构件受力情况,得出截割减速器行星架受到的切向力和转矩最大。运用有限元分析软件对双壁整体、双壁分开及单壁式行星架分别进行加载受力分析,双壁整体式行星架最大应力72.5 MPa,最大变形0.10 mm;双壁分开式行星架最大应力220.99 MPa,最大变形0.11 mm;单壁式行星架最大应力254.37 MPa,最大变形0.1163 mm。对最终设计的双壁整体行星架进行模态分析,结果显示共振频率在1107.7~1768.8 Hz,属于高频共振。所设计的行星架在井下使用情况良好。Taking the commonly used cutting reducer NGW planetary transmission in mining equipment as the research object,analyzed the force situation of each component of the planetary transmission,and concluded that the cutting reducer planetary carrier is subjected to the maximum tangential force and torque.Using finite element analysis software,the loading force analysis was conducted on the double wall integrated,double wall separated and single wall planetary carriers.The maximum stress of the double wall integrated planetary carrier was 72.5 MPa,and the maximum deformation was 0.10 mm;The maximum stress of the double wall separated planetary carrier is 220.99 MPa,and the maximum deformation is 0.11 mm.The maximum stress of a single wall planetary carrier is 254.37 MPa,and the maximum deformation is 0.1163 mm.Modal analysis was conducted on the final designed of the double wall integrated planetary carrier,and the results show that the resonance frequency was 1107.7-1768.8 Hz,belonging to high-frequency resonance.The designed planetary carrier works well underground.
