齒輪是搖臂鉆床傳動作業勞動高強度的部件，下面我們來說說對3050搖臂鉆床齒(chi)輪(lun)的(de)要求有(you)(you)哪些。齒(chi)面應(ying)有(you)(you)滿(man)足的(de)硬度(du)和耐磨性(xing)，以避免(mian)齒(chi)面磨損、點蝕(shi)、膠(jiao)合以及塑性(xing)變形(xing)等(deng)失效(xiao)。輪(lun)齒(chi)心部應(ying)有(you)(you)滿(man)足的(de)強度(du)和較好的(de)韌性(xing)，以避免(mian)齒(chi)根折斷忽然抵抗沖(chong)擊載荷(he)。應(ying)有(you)(you)出色的(de)加工工藝功(gong)能及熱處理功(gong)能，以便加工和提(ti)高力學(xue)功(gong)能。

齒(chi)輪(lun)(lun)是3050搖臂(bei)鉆(zhan)床整(zheng)體(ti)(ti)結構中的(de)(de)(de)一個重要組成部分，它的(de)(de)(de)質量(liang)直接影響(xiang)著鉆(zhan)床的(de)(de)(de)運用壽數。齒(chi)輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)體(ti)(ti)系是機床作業的(de)(de)(de)中心裝置(zhi)，齒(chi)輪(lun)(lun)是依(yi)托(tuo)齒(chi)的(de)(de)(de)嚙(nie)合傳(chuan)遞扭(niu)矩的(de)(de)(de)輪(lun)(lun)狀機械零件(jian)。齒(chi)輪(lun)(lun)通過與其它齒(chi)狀機械零件(jian)（如另(ling)一齒(chi)輪(lun)(lun)、齒(chi)條(tiao)、蝸桿）傳(chuan)動(dong)(dong)(dong)，可完結改(gai)動(dong)(dong)(dong)轉(zhuan)速與扭(niu)矩、改(gai)動(dong)(dong)(dong)運動(dong)(dong)(dong)方向和改(gai)動(dong)(dong)(dong)運動(dong)(dong)(dong)方法等(deng)功(gong)用。相(xiang)對來(lai)說3050搖臂(bei)鉆(zhan)床選用聯(lian)軸(zhou)器(qi)的(de)(de)(de)傳(chuan)動(dong)(dong)(dong)方法好，聯(lian)軸(zhou)器(qi)傳(chuan)動(dong)(dong)(dong)功(gong)率要比皮帶傳(chuan)動(dong)(dong)(dong)功(gong)率高(gao)(gao)。聯(lian)軸(zhou)器(qi)傳(chuan)動(dong)(dong)(dong)能(neng)夠做到無額外能(neng)量(liang)損耗、傳(chuan)動(dong)(dong)(dong)件(jian)和被傳(chuan)動(dong)(dong)(dong)件(jian)之間無空隙傳(chuan)動(dong)(dong)(dong)，所以(yi)功(gong)率最(zui)高(gao)(gao)。
