摘　　要：鼓形齿联轴器作为一种可移式刚性联轴器,在机械传动系统中扮演着重要角色。压力角是决定齿廓形状的关键参数,影响着鼓形齿齿面承载性能。为探究压力角与鼓形齿联轴器齿面承载性能的关系,通过有限元模拟分析,得到了四组不对中角下单齿和全齿啮合时的齿面等效应力,分析了不同间隙下压力角对齿面承载性能和接触齿对数的影响。研究结果表明:不对中情况下压力角对于齿面承载性能的影响高于理想对中情况,且接触齿对数随着压力角的增大总体呈上升趋势;间隙和压力角同时影响齿面承载性能,当存在间隙时随着压力角的增大,齿面承载性能先增大后减小,而无间隙时压力角越大齿面承载性能越高。The crown gear coupling,as a removable rigid coupling,plays a significant role in mechanical transmission systems.The pressure angle is a crucial parameter that determines the tooth profile shape and affects the tooth surface load capacity of crown gears.To investigate the relationship between the pressure angle and the load capacity of couplings gear surface,through finite element simulation analysis,the four groups tooth surface equivalent stress were obtained between single-tooth and full-tooth engagement under angle-misaligned,and analyzed the influence of pressure angle on tooth surface bearing performance and contact tooth number under different clearances.The research results show that the influence of pressure angle on the load-bearing capacity of tooth surface under misalignment conditions is higher than that under ideal alignment,and the number of contact teeth show an upward trend overall with the increase of pressure angle.The clearance and pressure angle both affect the load-bearing performance of the tooth surface.When there is a clearance,the load-bearing performance of the tooth surface first increases and then decreases with the increase of pressure angle.However,when there is no clearance,the larger the pressure angle,the better the load-bearing performance of the tooth surface.
