摘　　要：针对异向大型挤压造粒机组主齿轮箱输入轴低速齿轮损坏案例,使用MASTA软件建立主齿轮箱动力学模型。从振动噪声和齿面接触两方面分析低速小齿轮齿面损坏原因,并给出新的修形方案和齿轮制造误差控制的改进建议,避免齿轮副损坏情况再次发生。As to the case of low-speed gear damage on the input shaft of the main gearbox of a large-scale extrusion granulation unit,this study established a dynamic model of the main gearbox with MASTA software.It was analyzed from two aspects of vibration noise and tooth surface contact for digging out the causes of the surface damage of low-speed pinion,and a new modification scheme and improvement suggestions of gear manufacturing error control are given to avoid the recurrence of damage to the gear pair.
