提出一种在转子上设置虚拟支承的方法 ,以保证弧齿锥齿轮的啮合稳定性 ,并采用传递矩阵法 ,建立了弧齿锥齿轮 -转子系统的振动模型。给定的一对弧齿锥齿轮在工作过程中的啮合状态包括实际参与啮合的轮齿对数 ,每对轮齿分担的载荷和啮合点的位置 ,其中啮合点的位置应限制在一定的范围内而不应出现边缘接触 ,此即轮齿啮合的稳定性。由于实际工况的复杂性 ,通过改变虚拟支承的数量和位置 ,以使弧齿锥齿轮的啮合稳定性得以保证
A method of setting virtual support on the rotor is proposed to ensure the meshing stability of spiral bevel gear. The vibration model of spiral bevel gear - rotor system is established by transfer matrix method. The meshing state of a given pair of spiral bevel gears during operation includes the number of gear pairs actually involved in meshing, the load shared by each pair of teeth, and the position of the meshing point, where the meshing point position should be limited to a certain range And should not appear within the edge of contact, that is, the stability of gear meshing. Due to the complexity of the actual working conditions, the meshing stability of the bevel gear can be ensured by changing the number and position of the virtual supports
