摘要
将压力角作为传力特性评价指标,用以指导双相激波摆杆活齿传动设计参数的选取。基于活齿啮合理论,运用复数矢量法建立齿形方程,以两类典型传动为研究对象,推导了压力角解析式,分析了各压力角的变化规律,确定了压力角与摆幅系数、中心轮齿数、基圆半径、摆杆长度以及中心距的关系。运用正交试验法,选取四因素三水平试验表进行方案设计,获得了各设计参数对压力角的影响权重。
The pressure angle was used as the evaluation index of force transmission characteristics to guide the design parameters of double generating wave swing rod movable tooth drive.A tooth profile equation was established by complex vector method based on the meshing theory of movable tooth drive.Taking two typical transmission types as the research objects,the calculation formulae of pressure angle were deduced.The changing laws of each pressure angle were analyzed to ascertain influences of oscillation amplitude coefficient,teeth number of central wheel,radius of base circle,length of swing rod and center distance on pressure angles.By employing the orthogonal experiment,the scheme design was carried out based on experimental table with 4factors and 3levels to obtain the influence weights of each design parameter on pressure angle.
