修理花键轴通常采用侧面堆焊然后铣削至标准尺寸的方法。但是,由于堆焊操作耗工时多,堆焊工件硬度低和焊后表面加工困难,以及易于产生热应力,所以,采用这种修复方法是不适宜的。在机械制造中,花键轴基本上是用塑性变形的方法制成的。此种方法可提高生产率和节省金属。因此,修理花键轴时,采用滚轮辗轧来修复花键的方法是很有前途的。塑性变形法修复花键所用的工具为双滚轮轧头(图1)。块板10上装有滚轮8和滚轮轴,滚轮轴用螺钉锁定,并通过油眼9进行润滑。块板用螺栓固定在底座1的长槽内。加力螺杆12可使块板作纵向移动。用螺栓和锁紧螺母可调整块板的横向位置并将其
Repairing a spline shaft is usually done by side-surfacing and then milling to standard dimensions. However, this method of repair is not suitable due to the time and labor required for the build-up operation, the low hardness of the build-up workpieces and the difficulty of working the surface after welding, as well as the tendency to generate thermal stresses. In mechanical manufacturing, the spline shaft is basically made by a method of plastic deformation. This method can improve productivity and save metal. Therefore, the repair of spline shaft, the use of roller rolling repair spline method is very promising. Plastic deformation method to repair the spline tool used for double-roller head (Figure 1). The plate 10 is provided with a roller 8 and a roller shaft which is screwed and lubricated by an oil eye 9. The plate is bolted to the long groove of the base 1. Afterburner screw 12 allows the plate to move longitudinally. Use bolts and lock nuts to adjust the lateral position of the plate and set it
