一、引言 齿轮联轴器在重型机械,如卷扬机、轧机、起重机械、行车等设备上使用十分广泛。 齿轮联轴器的功能不仅使左、右两轴牢固联接,并且要把两轴轴心间的相对偏移或偏斜得到补偿、齿轮联轴器上两个主要零件是内齿圈及外齿轴套。为了改善齿的接触条件,故内、外齿的啮合间隙较大,而轮齿的定心直径(即外齿的顶圆直径d_(e1)和内齿的根圆直径D_(12))的尺寸精度要比一般渐开
I. INTRODUCTION Gear couplings are widely used on heavy machinery, such as winches, rolling mills, cranes, vehicles and other equipment. The function of the gear coupling not only makes the left and right shafts firmly connected, but also compensates for the relative deviation or skew between the two shaft axes. The two main parts of the gear coupling are the ring gear and the external gear Sleeve. In order to improve the contact conditions of the teeth, the meshing clearances between the inner and outer teeth are large, and the centering diameters of the teeth (ie, the diameter d_ (e1) of the top circle of the external teeth and the diameter D_ (12) of the root circle of the internal teeth) Dimensional accuracy than the general involute
