臨(lin)清DC單(dan)向軸承產品詳情

DC單向軸承

DC單(dan)(dan)向軸承是在一(yi)(yi)(yi)個方向上可(ke)以自由轉動(dong)(dong),而在另(ling)一(yi)(yi)(yi)個方向上鎖死的(de)一(yi)(yi)(yi)種軸承。單(dan)(dan)向軸承也叫超越離合器,只(zhi)是根據(ju)行業不同,作用不同來命(ming)名的(de)。單(dan)(dan)向軸承的(de)金屬外殼里,包含很多個滾(gun)(gun)軸,滾(gun)(gun)針或者(zhe)滾(gun)(gun)珠,而其滾(gun)(gun)動(dong)(dong)座(zuo)(穴)的(de)形狀(zhuang)使它只(zhi)能(neng)向一(yi)(yi)(yi)個方向滾(gun)(gun)動(dong)(dong),而在另(ling)一(yi)(yi)(yi)個方向上會(hui)產生(sheng)很大的(de)阻力(所謂(wei)“單(dan)(dan)向”)。
