摘　　要：侧隙补偿是高精密齿轮传动领域的研究热点,侧隙变大会导致传动稳定性变差,而过小的侧隙会导致齿轮非工作面发生干涉。结合航空薄辐板齿轮的特点,根据轮系传动链中的小侧隙与传动精度间的几何关系,提出了考虑侧隙的齿轮结构参数计算方法,基于有限元原理建立了小侧隙薄辐板齿轮的啮合刚度计算方法,通过正交试验法分析了齿轮参数对啮合刚度的影响并构建了考虑侧隙与辐板参数变化的准静态传递误差计算公式,为小侧隙薄辐板齿轮副的刚度及准静态传递误差计算提供了技术依据。Backlash compensation is a research hotspot in the field of high precision gear transmission.Large backlash would lead to poor transmission stability,while small backlash would result in non-working face interference of the gear.Combined with the characteristics of the thin-spoke aviation gear,structure parameter calculation method is proposed according to geometric relation of small backlash and transmission accuracy of chain.Based on finite element theory,the meshing stiffness model of small backlash and thin-spoke gear is established.The effects of parameters on meshing stiffness are analyzed through orthogonal experiment,furthermore meshing stiffness calculation model is obtained using radial basis function neural network which would provide technical support for rapid perdiction of small backlash and thin-spoke gear.
