摘　　要：双重功率分支又称为功率四分支,其特点是在两级减速齿轮传动装置中的第Ⅰ级采用功率两分支,第Ⅱ级每个小齿轮再采用两分支,实现双重功率分支。双重功率分支机构可进一步提高传动装置功率密度比,有效解决船舶传动装置大扭矩、大功率、大速比的要求。在双重功率分支机构中,为实现其均载要求,将Ⅱ级小齿轮做成浮动结构。采用有限元法对自行设计的双重功率分支试验箱中的Ⅱ级小齿轮进行了强度校核计算,对试验件的设计具有重要的指导作用。The double power embranchment is entitled power four embranchments.It adopts power two embranchment in the first class of gear transmission and each small gear adopts power two embranchment in the second class of gear transmission,it can achieve the double power embranchment.The double power embranchment can further enhance power density ratio of gearing.It is effective to overcome large torsion,large power and large speed ratio in the shipping gearing.In the double power embranchment,the small gears are floating framework in the second class gear transmission to achieve load sharing.We carry through strength check to the small gears in the second class gear transmission with FEA,which provides the effective guidance to design of testing part.
