按照齒輪齒面硬度不同，熱處理工藝的不同，可以將齒輪減速機(ji)分為，軟齒面減速機，中硬齒面減速機,硬齒面減速機三大類。今天就來淺談一下硬齒面減速機與軟齒面減速機的三大不同之處，和之間的區別。

 齒(chi)(chi)輪(lun)(lun)減(jian)速(su)(su)機(ji)(ji)(ji)是(shi)現在工業中(zhong)使(shi)用最(zui)廣泛的(de)減(jian)速(su)(su)機(ji)(ji)(ji)之一(yi)(yi)，齒(chi)(chi)輪(lun)(lun)減(jian)速(su)(su)機(ji)(ji)(ji)結構緊湊合理(li)，傳動效率高，維護方便，維修零件容(rong)易替(ti)換(huan)，安裝簡易，是(shi)機(ji)(ji)(ji)械設備上首選的(de)減(jian)速(su)(su)機(ji)(ji)(ji)之一(yi)(yi)。而齒(chi)(chi)輪(lun)(lun)減(jian)速(su)(su)機(ji)(ji)(ji)根(gen)據齒(chi)(chi)輪(lun)(lun)硬(ying)度分為硬(ying)齒(chi)(chi)面減(jian)速(su)(su)機(ji)(ji)(ji)與軟齒(chi)(chi)面減(jian)速(su)(su)機(ji)(ji)(ji)兩(liang)種。那么硬(ying)齒(chi)(chi)面減(jian)速(su)(su)機(ji)(ji)(ji)與軟齒(chi)(chi)面減(jian)速(su)(su)機(ji)(ji)(ji)的(de)區別究竟在哪里？結構上或者原理(li)上是(shi)否有(you)所區別，下面就跟大(da)家一(yi)(yi)起探(tan)討。

   在外形(xing)上(shang)(shang)、結構上(shang)(shang)和原理(li)(li)上(shang)(shang)其實硬(ying)齒(chi)(chi)(chi)(chi)面減(jian)(jian)(jian)速(su)機(ji)(ji)(ji)(ji)和軟齒(chi)(chi)(chi)(chi)面減(jian)(jian)(jian)速(su)機(ji)(ji)(ji)(ji)的幾乎沒(mei)有區別，主要在齒(chi)(chi)(chi)(chi)輪鍛造(zao)材(cai)料和后(hou)期處理(li)(li)上(shang)(shang)有所差異，造(zao)成兩種齒(chi)(chi)(chi)(chi)輪減(jian)(jian)(jian)速(su)機(ji)(ji)(ji)(ji)的負載、壽命及使用(yong)范圍(wei)不同，根據齒(chi)(chi)(chi)(chi)輪減(jian)(jian)(jian)速(su)機(ji)(ji)(ji)(ji)的齒(chi)(chi)(chi)(chi)輪硬(ying)度的大小，將齒(chi)(chi)(chi)(chi)輪減(jian)(jian)(jian)速(su)機(ji)(ji)(ji)(ji)分(fen)為硬(ying)齒(chi)(chi)(chi)(chi)面減(jian)(jian)(jian)速(su)機(ji)(ji)(ji)(ji)和軟齒(chi)(chi)(chi)(chi)面減(jian)(jian)(jian)速(su)機(ji)(ji)(ji)(ji)。
 

   一般來說，重型機(ji)(ji)(ji)械上用(yong)(yong)的(de)大(da)功(gong)率(lv)的(de)齒(chi)(chi)(chi)(chi)(chi)(chi)輪減(jian)(jian)(jian)速機(ji)(ji)(ji)的(de)齒(chi)(chi)(chi)(chi)(chi)(chi)輪都是采用(yong)(yong)硬(ying)(ying)度高的(de)材(cai)(cai)料鍛造(zao)而成，比如45鋼(gang)，采用(yong)(yong)滲碳淬火(huo)工藝后使(shi)硬(ying)(ying)度達到(dao)350HBS以上，達到(dao)這個硬(ying)(ying)度以上的(de)齒(chi)(chi)(chi)(chi)(chi)(chi)輪減(jian)(jian)(jian)速機(ji)(ji)(ji)就(jiu)稱之為硬(ying)(ying)齒(chi)(chi)(chi)(chi)(chi)(chi)面(mian)(mian)齒(chi)(chi)(chi)(chi)(chi)(chi)輪減(jian)(jian)(jian)速機(ji)(ji)(ji)。其實硬(ying)(ying)齒(chi)(chi)(chi)(chi)(chi)(chi)面(mian)(mian)齒(chi)(chi)(chi)(chi)(chi)(chi)輪減(jian)(jian)(jian)速機(ji)(ji)(ji)除了齒(chi)(chi)(chi)(chi)(chi)(chi)輪的(de)硬(ying)(ying)度高，其輸(shu)出軸、輸(shu)入軸的(de)硬(ying)(ying)度也比軟齒(chi)(chi)(chi)(chi)(chi)(chi)面(mian)(mian)齒(chi)(chi)(chi)(chi)(chi)(chi)輪減(jian)(jian)(jian)速機(ji)(ji)(ji)高出許多。因(yin)為硬(ying)(ying)齒(chi)(chi)(chi)(chi)(chi)(chi)面(mian)(mian)減(jian)(jian)(jian)速機(ji)(ji)(ji)要求承載(zai)力(li)強，所以箱體的(de)材(cai)(cai)料也是采用(yong)(yong)鑄鐵鍛造(zao)，能很(hen)好的(de)應付在高負載(zai)和惡劣環(huan)境下產生的(de)振動和沖擊(ji)力(li)。使(shi)用(yong)(yong)壽命更長，適用(yong)(yong)于大(da)功(gong)率(lv)，高負載(zai)或者使(shi)用(yong)(yong)環(huan)境惡劣的(de)機(ji)(ji)(ji)械上使(shi)用(yong)(yong)。由于材(cai)(cai)料更憂(you)和工藝的(de)復雜(za)，硬(ying)(ying)齒(chi)(chi)(chi)(chi)(chi)(chi)面(mian)(mian)減(jian)(jian)(jian)速機(ji)(ji)(ji)的(de)價格要相對于軟齒(chi)(chi)(chi)(chi)(chi)(chi)面(mian)(mian)減(jian)(jian)(jian)速機(ji)(ji)(ji)高。

　　軟齒面齒輪減速機就是普通的、齒輪沒經過硬度加工或精度沒達到硬齒面要求的產品。軟齒面減速機應用領域非常廣泛，各種紡織機械、包裝機械、輸送帶、流水線等較小功率的機械。其工藝簡單，相對低廉的價格也負荷客戶要求，是工業中使用最多的減速機之一。

　　在選購齒(chi)輪減(jian)(jian)速(su)機時(shi)，首先要(yao)了(le)解(jie)自己所選的減(jian)(jian)速(su)機是(shi)否能滿足要(yao)求，如(ru)果(guo)軟齒(chi)面(mian)(mian)減(jian)(jian)速(su)機能滿足要(yao)求的話(hua)就(jiu)無需選用(yong)硬齒(chi)面(mian)(mian)減(jian)(jian)速(su)機，其功能都是(shi)一(yi)樣的。但是(shi)如(ru)果(guo)需要(yao)用(yong)到大功率，高(gao)負載的情況(kuang)下，就(jiu)只(zhi)能選用(yong)硬齒(chi)面(mian)(mian)減(jian)(jian)速(su)機，如(ru)果(guo)冒險使用(yong)軟齒(chi)面(mian)(mian)減(jian)(jian)速(su)機，很可能會發生齒(chi)輪斷裂，無法驅動等情況(kuang)。
