一、前言齿轮联轴器是回转机械重要的构件之一,它不仅仅是用来连接主、从动轴传递扭矩,而且还要求能补偿两轴间的安装误差,并吸收热变形,以减小机械振动实现平稳运转。齿轮联轴器结构型式如图1所示,主要由带齿的内齿圈和外齿套组成,通过内外齿啮合来传递扭矩。图1(b)所示的齿轮联轴器,其内齿圈为浮动体。与其它型式的联轴器相比,齿轮联轴器具有外形小,传递动力大等优点。但应指
I. Introduction Gear coupling is one of the important components of rotary machinery, it is not only used to connect the main and driven shaft torque transmission, but also required to compensate for installation errors between the two axes and absorb thermal deformation to reduce Small mechanical vibration to achieve smooth operation. Gear coupling structure shown in Figure 1, mainly by the toothed ring gear and external gear sets, through the internal and external gear meshing to transmit torque. Figure 1 (b) shows the gear coupling, the ring gear for the floating body. Compared with other types of coupling, the gear coupling has the advantages of small size, large transmission power and so on. But it should mean
