16、進(jìn)行選擇。5、拉伸與壓縮將0形圈安裝在溝槽內(nèi)時(shí),要受到拉伸或壓縮。若拉伸和壓縮的數(shù)值過(guò)大,將導(dǎo)致0形圈截面過(guò)度增大或減少,因?yàn)槔?%相應(yīng)地使截面直徑W減少約為0.5%。對(duì)于孔用密封,0形圈最好處于拉伸狀態(tài),最大允許拉伸量為6%;對(duì)于軸用密封,0形圈最好延其周長(zhǎng)方向受壓縮,最大允許周長(zhǎng)壓縮量為3%。6、0形圈用作旋轉(zhuǎn)軸密封0形圈也可用作低速旋轉(zhuǎn)運(yùn)動(dòng)及運(yùn)行周期較短的旋轉(zhuǎn)軸密封。當(dāng)圓周速度低于0.5m/s時(shí),須考慮拉長(zhǎng)的橡膠圈受熱后會(huì)收縮這一現(xiàn)象,故選擇密封圈時(shí)其內(nèi)徑要比被它密封的軸徑約大2%。密封圈安裝在溝槽后,導(dǎo)致密封圈受到徑向壓縮,0形圈圈在溝槽中形成微量波紋狀,從而改善了潤(rùn)滑條件。7、安裝
