摘　　要：小断面、小转弯半径TBM在岩石破碎地质施工时,需要采用锚杆支护,以保障作业安全。现有锚杆钻机所采用的液压马达是柱塞式或行星转子式摆线马达,存在结构尺寸大,重量大的不足,而非圆齿轮马达具有结构紧凑、功重比高、抗污染能力强的特点,在小断面隧道掘进施工中具有明显的优势。介绍一种变中心距4-6型非圆齿轮马达的工作原理及组成,并针对非圆齿轮马达高阶椭圆节曲线及齿廓设计难度大的问题,提出采用双圆弧节曲线,并运用非线性目标规划方法,建立非线性约束关系式,再通过Matlab求解最优值,确定出双圆弧非圆齿轮马达太阳轮和内齿圈节曲线参数,进一步设计太阳轮及内齿圈齿廓。该方法简化了非圆齿轮马达的设计难度,可为小断面TBM支护用锚杆钻机的研制提供设计参考。When the TBM with asmallface and a smallturningradius works in rock fragmentation geology,it requires support by the bolt to ensure the safety of operation.The hydraulic motors used in the existing roof bolters are piston or planetary rotor cycloid motors,which have the shortcomings of large structural dimensions and weights,while non-circular gear motors,with the characteristics of compact structure,high power-to-weight ratio and strong pollution resistance,have obvious advantages in the construction of small-face tunnel boring.The working principle and composition of a 4-6 non-circular gear motor withvariable center distanceare introduced,and in view of the difficulty in designing the high-order elliptic pitch curve and tooth profile of the non-circular gear motor,it is proposed to adopt the double-circular-arc pitch curve,use nonlinear objective programming method to establish the nonlinear constraint equation,and then solve the optimal value through Matlab to determine the parameters of the sun gear and inner ring pitch curves of the double-circular-arc and noncircular gear motor and to further design the sun gear and inner ring tooth profiles.This method simplifies the design of noncircular gear motors,which can provide a design reference for the development of roof bolters for small-face TBM support.
