怎样检修十字轴?

2006-12-18

十字轴的主要损坏形式有:磨损、有裂纹、十字轴轴颈表面有严重的损伤(如金属剥落、有明显凹陷等)。若轴颈表面有轻微剥落,应用油石打光剥落表面后继续使用,若有严重损伤,则应更换十字轴。另外,对十字轴,还应检修如下内容: (1)检查十字轴轴承与十字轴颈的配合间隙,将十字轴夹在台钳上,滚针轴承套在十字轴轴颈上,用百分表抵住轴承壳外面Z高点,用手上、下推动滚针轴承壳,百分表上指针移动的变化值即为轴承与十字轴的配合间晾。此间隙应小于0.05mm。 (2)十字轴轴承滚针不得有严重的烧蚀、锈蚀、疲劳剥落,否则应更换。更换时,应保证滚针的长度、直径一致。 (3)十字轴承益板(支承片)上止动突起部分应完全可靠,螺栓应完好,螺纹损伤应不得多于两牙,不符合耍求应视情况修复或更换。
