等截面薄壁四點(diǎn)接觸球軸承因?yàn)榕c普通滾動(dòng)軸承不同,對于這個(gè)系列的等截面薄壁四點(diǎn)接觸球軸承,不管軸承內(nèi)徑大小,它的橫截面是保持不變的,因此也稱為等截面薄壁四點(diǎn)接觸球軸承。開式是指不帶任何密封蓋的等截面薄壁四點(diǎn)接觸球軸承。
等截面薄壁四點(diǎn)接觸球軸承與薄壁角接觸球軸承、薄壁深溝球軸承的區(qū)別在于其溝道的形狀。等截面薄壁四點(diǎn)接觸球軸承每側(cè)的滾道有2個(gè)半徑圓心,均偏離鋼球的中心線。這種結(jié)構(gòu)使等截面薄壁四點(diǎn)接觸球軸承在鋼球與滾道間形成四點(diǎn)接觸。
等截面薄壁四點(diǎn)接觸球軸承的溝底深度與壁角接觸球軸承、薄壁深溝球軸承一樣(鋼球直徑的25%)。深溝球結(jié)構(gòu)與四點(diǎn)接觸結(jié)構(gòu)均能使軸承承受徑向、軸向載荷以及力矩載荷。類似于一對角接觸球軸承的背對背組合。由于具有承受聯(lián)合載荷的徑向、軸向、以及力矩的能力,等截面薄壁四點(diǎn)接觸球軸承常常用于替代成對角接觸球軸承、成對圓錐滾子軸承,或者球或滾子推力軸承和深溝球軸承的組合。
等截面薄壁四點(diǎn)接觸球軸承通常具有一定的徑向游隙。四點(diǎn)接觸球薄壁軸承的接觸角與軸向載荷能力與該游隙無關(guān)。相反,在承受很大軸向載荷或者彎矩時(shí),需要減小游隙,以免接觸角過大。很多應(yīng)用場合中需要更高的剛度,等截面薄壁四點(diǎn)接觸球軸承可以施加載荷。使用超過滾道空間的大尺寸球可以獲得預(yù)載荷。此時(shí),即使沒有外部載荷,球和滾道也會(huì)存在彈性變形。
注意:等截面薄壁四點(diǎn)接觸球軸承在通常設(shè)計(jì)中為單獨(dú)使用,在一根軸上使用2套薄壁四點(diǎn)接觸球軸承有可能產(chǎn)生附加的摩擦力矩。
等截面薄壁四點(diǎn)接觸球軸承增加了抗摩擦的能力,提高了運(yùn)行的精度。解決了傳統(tǒng)軸承的尺寸和重量問題,以及軸和軸承座的尺寸和重量問題。四點(diǎn)接觸球軸承的獨(dú)特之處在于,可以雙向承受徑向載荷和軸向載荷,其極薄的橫截面使其能夠?yàn)榫哂芯徛蜷g歇旋轉(zhuǎn)的輕中型應(yīng)用提供極大的尺寸和重量減輕。因?yàn)橐粋€(gè)四點(diǎn)接觸球軸承經(jīng)??梢蕴娲鷥蓚€(gè)軸承,所以它使設(shè)計(jì)更簡潔。四點(diǎn)接觸球軸承可以根據(jù)客戶的需求提供不同內(nèi)部預(yù)壓和游隙??梢酝ㄟ^使用比內(nèi)外圈滾道之間空隙更大的滾珠來實(shí)現(xiàn)。當(dāng)然,即使是在沒有外部載荷的情況下,滾珠和滾道也會(huì)有一定彈性變形。
軸承材質(zhì):有高碳洛軸承鋼Gcr15和不銹鋼440C、9cr18等。
滾動(dòng)體:有陶瓷球,鋼球等。
使用等截面薄壁四點(diǎn)接觸球軸承可帶來以下益處:
更高的動(dòng)載荷承載能力
降低對重軸向載荷的敏感度
提高耐磨性
降低噪音和振動(dòng)水平
減少摩擦熱量
顯著延長軸承的使用壽命

NKG等截面薄壁四點(diǎn)接觸球軸承(X型)可以根據(jù)客戶的需求提供不同的內(nèi)部預(yù)壓和游隙。這可以通過使用比內(nèi)外圈滾道之間空隙更大的滾珠來實(shí)現(xiàn)。當(dāng)然,即使是在沒有外部載荷的情況下,滾珠和滾道也會(huì)有一定彈性變形。等截面薄壁四點(diǎn)接觸球軸承能承受徑向載荷、雙向推力載荷和傾覆力矩,經(jīng)??梢蕴娲鷥蓚€(gè)軸承,軸承在滾道和鋼球間實(shí)現(xiàn)了四點(diǎn)接觸,設(shè)計(jì)更簡潔。
