【摘要】：以风电斜齿行星轮系为对象,考虑多间隙和摩擦对齿轮啮合的影响,建立完整的风电斜齿行星齿轮系有限元模型;结合非线性动力学方法,研究齿轮啮合时冲击应力的特点和变化规律,分析不同转速和负载对各齿轮冲击应力的影响。通过分析得到冲击速度对啮合冲击影响较大,负载会影响到系统的振动情况,在齿轮设计时要考虑减少冲击和振动的措施。
[Abstract]:Taking the helical planetary gear train of wind power as an example, considering the influence of multiple clearances and friction on gear meshing, a complete finite element model of helical planetary gear system of wind power is established, which is combined with nonlinear dynamic method. The characteristics and variation of impact stress in gear meshing are studied, and the influence of different speed and load on the impact stress of gear is analyzed. The results show that the impact velocity has a great influence on the meshing impact, and the load will affect the vibration of the system. Measures to reduce shock and vibration should be considered in gear design.
