齿(chi)(chi)轮(lun)磨(mo)削裂纹的(de)形成原因及其预防(fang)(fang)措施是一个重要(yao)的(de)问题。以(yi)下是一些常见(jian)的(de)原因和(he)相应的(de)预防(fang)(fang)措施：1. 齿(chi)(chi)根硬(ying)度(du)(du)降(jiang)低：热(re)处理后(hou)，齿(chi)(chi)根的(de)硬(ying)度(du)(du)可能(neng)(neng)会降(jiang)低，导致齿(chi)(chi)轮(lun)容易产生(sheng)裂纹。为(wei)了预防(fang)(fang)这种情(qing)况(kuang)，应保持渗碳淬火和(he)喷丸强化(hua)后(hou)在(zai)齿(chi)(chi)面和(he)齿(chi)(chi)根形成负的(de)压应力(li)层。这样(yang)可以(yi)明(ming)显提高齿(chi)(chi)轮(lun)的(de)抗弯疲劳强度(du)(du)和(he)承载能(neng)(neng)力(li)。2. 齿(chi)(chi)根沟(gou)(gou)槽设计(ji)不合理：齿(chi)(chi)根沟(gou)(gou)槽槽底(di)狭小(xiao)，散热(re)能(neng)(neng)力(li)差(cha)，以(yi)及过度(du)(du)曲线处余量大(da)小(xiao)变化(hua)大(da)，都会导致磨(mo)削过程中产生(sheng)磨(mo)削烧(shao)伤(shang)和(he)磨(mo)削裂纹。为(wei)了预防(fang)(fang)这种情(qing)况(kuang)，应合理设计(ji)齿(chi)(chi)根沟(gou)(gou)槽，确(que)保槽底(di)宽度(du)(du)适当，散热(re)能(neng)(neng)力(li)良好，并(bing)且(qie)过度(du)(du)曲线处的(de)余量变化(hua)适中。此外，还应注意砂轮(lun)的(de)工作条(tiao)件，确(que)保其磨(mo)削效果良好。磨(mo)齿(chi)(chi)机前后(hou)角转动调(diao)整困难，可能(neng)(neng)需要(yao)调(diao)整液压油(you)箱门(men)。
