矩形花键是机械传动装置中常见的一类零件。由于配偶零件的相对滑动,往往造成矩形花键键侧的磨损而失效。对于键侧磨损失效的矩形花键,过去常应用手工电弧堆焊修复,但修复周期长,费工费料,经济性极差。对于一些要求较高的花键往往由于没有合适的修复工艺而不得不报废。 Rectangular spline is a common type of mechanical transmission parts. Due to the relative sliding parts of spouses, often resulting in rectangular spline-side wear and failure. Rectangular spline failure for the key side of the spline, the past often used manual arc surfacing repair, but the repair cycle is long, labor costs, very poor economy. For some of the more demanding splines often have to scrap because there is no suitable repair process.
