在机械制造工程中,常有大量的轮轴装配项目,且相当部分为过盈配合装配法。传统的过盈装配方法是将工件用油浴、烤烧或箱式电炉加热等方法,使孔径胀大,然后迅速装于轴上,待冷却后轮孔径缩小,部件就牢牢地固定在一起。然而这些方法都有一个热效率低、加热时间长,有污染物产生等特点,操作起来费时费力成本较高。 于是,我们考虑用电磁感应的方法对金属轮工件进行加
In mechanical engineering, there are often a large number of axle assembly projects, and a considerable part of the interference fit assembly method. The traditional method of interference assembly is the work piece with an oil bath, roasting or heating with a box furnace and other methods to make the aperture expansion, and then quickly installed on the shaft, to be cooled rear wheel aperture reduced, the components are firmly fixed together . However, these methods have a low thermal efficiency, heating a long time, contaminants and other characteristics of the time-consuming and laborious to operate high cost. Therefore, we consider the use of electromagnetic induction method of metal wheel workpiece plus
