一、引言不论是在制造业还是在修理业，为了保证机件正常运转，达到预定的工作性能和使用寿命，在安装联轴器时，必须对联轴器两轴进行调整，使之具有较高的同轴度。过去，通常采用的传统方法需要操作者利用厚薄规、直尺和百分表等简单的工具，凭借自己熟练的测量技术和丰富的 I. Introduction Both in the manufacturing industry or in the repair industry, in order to ensure the normal operation of the machine to achieve the predetermined performance and service life, the installation of the coupling, the coupling must be adjusted on both axes so that it has a higher The coaxiality. In the past, the traditional methods commonly used required operators to use simple tools such as thickness gauge, ruler and dial indicator, with their own sophisticated measurement techniques and rich
