一、镶套修理
将要修理的轴颈部位先在车床上车一刀，其车掉部分不得超过轴径的5%。再车一个套圈，把车好的套圈加热以红装的方法装配到轴颈上。然后进行精车，或者在磨床上磨削到符合图纸规定的尺寸。
二、镶两半套
此法特别适用于带螺纹的轴，不宜直接镶套的轴颈部位。两半套是用中碳钢车成一个薄壁套圈，它的外径跟轴承内圈孔配合，安装时沿轴线用手锯锯开，或者用铣床切开。事先把已磨损部位轴颈车削成一段凹槽。阴摘的外径与套圈的内径尺寸相同，然后把两半套扣上，临末安装轴承。为了不使软颈截面面积减小太多，两半套的厚度不宜过厚，一般为软颈尺寸的2^-2.5%。如直径105毫米的轴，两半套的尺寸为2毫米。
三、采用电镀
当轴承的轴颈部位磨损或加工超差时，可以用镀铬、镀铁等方法修复。镀铬或镀铁后要在磨床上再磨削到符合图纸的尺寸要求。
四、金属喷涂
当轴承的轴颈部位磨损或加工超差时，可以采用金属喷涂的方法修复轴颈，喷涂以前把轴颈部位车到一定尺寸，再喷涂金属，喷涂后可用车床或者磨床加工到符合图纸的尺寸要求。
五、电焊修补
将磨损的轴须部位，先在车床上粗车一刀，然后采用手工电焊，把轴焊到一定尺寸，在机床上直接加工到图纸要求的尺寸。为了预防由于焊补时轴产生弯曲变形，应采用反向变形的对称平衡式复焊法。
六、采用滚花、冲孔、挂锡
当轴承的轴颈部位有轻微的磨损，或者加工时超差不大，失去配合紧度时，可以在轴颐配合部位处，采用以下方法做为临时应急处理。
滚花：把安装轴承部位的轴颈在车床上用滚花刀滚花。由于滚压出花纹，使轴颈尺寸增加。
冲孔：人工用样冲子在轴颈部位按圆周均匀打出小孔，靠小孔的突起部分增加轴颐尺寸。
挂锡：在轴须上挂上一层焊锡来达到增加轴顶尺寸的方法。挂锡前应将轴顶上的油污用稀盐酸溶液清洗，然后再用清水冲洗凉干后挂锡，以便使锡层与轴颈接合良好。
如果是长久性部件或是重要部件，不宜采用这些方法。
