螺旋伞齿轮出现热处理变形怎么办

发布时间:2020-05-12人气:9

      螺旋伞齿轮在热处理过程中,要是处理不当回出现变形的情况,从而影响螺旋伞齿轮的功能,那么在进行热处理的时候有哪些方法能避免螺旋伞齿轮出现变形的情况呢?

      先来说as视讯棋牌从选材、热处理、加工等方面来进行入手,因为这几方面影响着齿轮热处理变形的因素,首先来说分析其产生的原因,需要通过良好的设计加上适当的选材同时配合热处理工序和机械加工工艺之间的配合等相应措施,减少齿轮热处理变形,从而提升齿轮加工精度,当然您也需要注意的是在正火调质处理当中,一定要保持炉膛温度的均匀,同时采用其工位器具,使工件均匀地加热及冷却,不能将其堆放在一起。如果需要钻孔来减轻齿轮的质量,那么应该将钻孔工序安排在热处理之后进行。当然齿轮的热处理采用零件变形较小的齿面高频淬火;高频淬火之后得到的齿面具有高的强度、硬度、耐磨性的极限,使其心部仍保持足够的塑性和韧性。当然为了减少变形的出现,齿面高频淬炎应该采用较低的淬火温度和较短的加热时间、均匀加热、缓慢冷却。
