齒輪螺旋式角轉變對抗壓強度的影響因為一般齒輪切削生產加工時輪齒也不磨生產加工，滲氮全過程中造成的脫碳層遺留下在鋼件表層，減少了齒輪輪齒的彎折疲勞極限，應用時產生全部齒從齒輪根處碎裂。當選用一般的淬火高溫淬火開展熱處理時，齒輪鍛坯硬度基礎可以獲得確保。但，當齒輪鍛坯在熱處理全過程中所在部位不另外，隔爆油冷式電滾筒鍛坯的硬度存有顯著的散差，泰州齒輪，促使熱處理以后齒輪的結締組織存有顯著差別，磨齒齒輪加工，部分乃至出現馬氏體，影響齒輪機械加工特性，造成其在滲氮解決以后出現形變回彈力、壓力角與螺旋式角轉變提升等難題。而齒輪螺旋式角的轉變立即影響到齒輪應用全過程中的抗壓強度，在裝配線應用以后將造成齒輪的徑向力提升，影響齒輪的使用期，后造成齒輪出現初期無效難題。而壓力角的轉變將促使齒輪運行全過程中出現噪聲，還促使齒輪的齒合區部位產生變化，影響齒輪的健身運動精密度。適合的芯部硬度能防止錐體齒輪的初期無效，一般采用35-40HRCl佳，芯部硬度過低抗壓強度不夠和芯部過高耐磨（沖擊性值低）很差都是造成錐體齒輪初期無效。
