 圓柱滾子軸承
|
|
圓柱滾子軸承特點(diǎn)：
1. 滾子與滾道為線接觸或修下線接觸，徑向承載能力大，適用于承受重負(fù)荷與沖擊負(fù)荷。
2. 摩擦系數(shù)小，適合高速，極限轉(zhuǎn)速接近深溝球軸承。
3. N型及NU型可軸向移動(dòng)，能適應(yīng)因熱膨脹或安裝誤差引起的軸與外殼相對(duì)位置的變化，可作自由端支承使用。
4. 對(duì)軸或座孔的加工要求較高，軸承安裝后外圈軸線相對(duì)偏斜要嚴(yán)加控制，以免造成接觸應(yīng)力集中。
5. 內(nèi)圈或外圈可分離，便于安裝和拆卸。
主要用途：
大中型電動(dòng)機(jī)、機(jī)車車輛、機(jī)床主軸、內(nèi)燃機(jī)、發(fā)電機(jī)、燃?xì)鉁u輪機(jī)、減速箱、軋鋼機(jī)、振動(dòng)篩以及起重運(yùn)輸機(jī)械等。 |
