为了确保车轴的安全性,在对其重要部位进行检查和全面检查时,要测量齿轮箱的轴向间隙。传统的测量方式是将千分表安装在磁性座上,利用磁性座的磁力吸附在车轴上进行测量。但是,由于磁性座吸附力较弱,在作业过程中,经常发生测量工具偏移或掉落现象,影响测量准确性和进度,且耗时较长。对此,东京地铁公司绫濑工场进行了改进,制作了测量专用夹具,利用此夹具可以稳固地将测量工具固定在车轴上,大幅缩短测量时间,提高了作业效率和测量的准确性,且该夹具适用范围广泛,可以进行推广应用。
In order to ensure the safety of the axle, in the important parts of its inspection and a comprehensive inspection, to measure the gear box axial clearance. The traditional method of measurement is to install the indicator on the magnetic base, the magnetic base of the magnetic adsorption on the axle for measurement. However, due to the weak magnetic adsorptive force of the magnetic base, the offset or drop of measurement tools often occurs during operation, which affects the accuracy and progress of measurement and takes a long time. In response, Tokyo Ayase Ayase factory has been improved, produced a special measuring fixture, the fixture can be used to firmly fix the measuring tool on the axle, greatly reducing the measurement time and improve the operational efficiency and accuracy of the measurement, and the Jig for a wide range of applications can be promoted.
