摘　　要：[目的]针对大功率混合动力船用离合器高效接合和脱开的工作需求,[方法]建立船用无侧隙楔形齿桨轴离合器接合过程的多体动力学模型,搭建AMESIM和ADAMS联合仿真模型,对滑动齿套在有无周向晃动误差时接合过程中的受力变化,以及液压缸内压力和流量变化进行分析。此外,对锥度为1/50,压力角为20°的船用无侧隙楔形齿桨轴离合器样机进行设计和搭建,并开展接合试验和轴向加载试验。[结果]结果表明:当输入端和输出端对齿准确时,滑动齿套在输入端外存在任意周向晃动误差时仍可在自身导向作用下完全接合。在液压系统压力为3 MPa时,离合器产生弹性变形,滑动齿套产生1.6 mm轴向位移。[结论]研究成果可为高性能船用无侧隙楔形齿桨轴离合器的优化设计提供一定参考。[Purpose]In response to the requirements of efficient engagement and disengagement of high performance hybrid marine clutches,[Method]a multi-body dynamic model of the engagement process of the ship's non-backlash wedge-shaped propeller shaft clutch is established,and a joint simulation model of AMESIM and ADAMS is built to analyze the force changes during the engagement process of the sliding gear sleeve with and without circumferential oscillation error,as well as the pressure and flow rate changes in the hydraulic cylinder.In addition,a prototype of a ship's non backlash wedge-shaped propeller shaft clutch with a taper of 1/50 and a pressure angle of 20°is designed and built,and engagement and axial loading tests are carried out.[Result]The results indicate that when the input and output ends are accurately aligned,the sliding gear sleeve can still fully engage under its own guidance if there is a circumferential oscillation error outside the input end.When the hydraulic system pressure is 3 MPa,the clutch undergoes elastic deformation and the sliding gear sleeve experiences an axial displacement of 1.6 mm.[Conclusion]The research results can provide some references for the optimization design of high performance non-backlash wedge type marine propeller shaft clutches.
