在联接两水平的同心轴时,往往由于制造和安装工艺上的误差而造成被联接两轴之间有不大的径向倾斜和轴向位移。为确保传递运动,通常采用齿轮联轴器、挠性联轴器或轮胎联轴器等来适应被联接两轴出现的径向倾斜和轴向位移。但它们的结构较复杂,通常需专业工厂生产制造。 When coupling two horizontal concentric shafts, there is often little radial tilt and axial displacement between the coupled shafts due to manufacturing and installation process errors. In order to ensure the transfer of movement, gear couplings, flexible couplings or tire couplings are often used to accommodate the radial and axial displacements of the coupled shafts. However, their structure is complicated and usually requires the manufacture of specialized factories.
