【摘要】：针对非圆齿轮的轮齿受力方向和从动轮惯性转矩具有时变性的特征,提出将非圆齿轮传动比线性分割成有限个微段后构建非圆齿轮动力学模型。在每个微段上,假设非圆齿轮受力方向不变,惯性转矩等效成负载阻力矩,利用圆齿轮动力学理论建立非圆齿轮副的扭振模型。对非圆齿轮副模型进一步扩展,推导出包含传动轴和减速齿轮在内的非圆齿轮传动系统的扭振模型,并将其应用于新型结晶器非正弦驱动系统的设计。通过数值方法计算出由非圆齿轮组成的驱动系统的时域响应,分析了系统的动态特性,不仅验证了模型的可行性,而且为新型驱动装置的应用提供了理论依据。
[Abstract]:Aiming at the force direction of non-circular gear teeth and the time-varying inertia torque of driven gear, a dynamic model of non-circular gear is constructed by dividing the transmission ratio of non-circular gear into finite micro-segments. Assuming that the force direction of non-circular gear is constant and the inertia torque is equivalent to the load resistance moment on each micro-segment, the torsional vibration model of non-circular gear pair is established by using the dynamic theory of circular gear. By further extending the model of non-circular gear pairs, the torsional vibration model of non-circular gear transmission system including drive shaft and deceleration gear is derived and applied to the design of a new type of mould non-sinusoidal drive system. The time domain response of the drive system composed of non-circular gears is calculated by numerical method, and the dynamic characteristics of the system are analyzed, which not only verifies the feasibility of the model, but also provides a theoretical basis for the application of the new drive device.
