關(guān)節(jié)軸承額定載荷與壽命計算

對于需要維護的關(guān)節(jié)軸承，應(yīng)定期更換軸承中的潤滑劑，此時軸承的壽命估算方法為：LR=αnαβL (擺次)式中系數(shù) α _ { h } 、 α _ { β } 取值如下表：

當關(guān)節(jié)軸承在分段載荷工作下，其壽命計算為：

式中：Ti一第i段載荷的作用時間；Li一第i段載荷下的計算壽命；nT=T/∑Tii=1n一載荷的分段數(shù)

SNBAL CALCULATION OFBASIC LOAD RATINGSAND SERVICELIFEOFSPHERICALPLAINBEARING

For the spherical plain bearing that needs maintenance,the lubricant should be replaced periodically,
herein estimating method of the bearing life is: V _ { R } = \arctan α _ { B } L (swing circles),
where:coefficient α _ { h } 、 α _ { β } is given by following table:

If the spherical plain bearing served undera segmented loading,its life can be calculated by the where:Ti— The acting time of i-th loading segment; Li— The calculating life of -th loading segment; n T=T/∑Ti i=1 n— Number of Load Segments

向心關(guān)節(jié)軸承RADIAL JOINT BEARING

向心關(guān)節(jié)軸承是由帶有內(nèi)球面的外圈禾 □帶有外球面的內(nèi)圈構(gòu)成一對滑動摩擦副，主要用于機械同心度要求不高，工作表面壓力較大且又要做低速擺動、傾斜或迥轉(zhuǎn)運動的機械機構(gòu)中。向心關(guān)節(jié)軸承的滑動摩擦副可由不同材料組成，主要有兩種：潤滑型(鋼對鋼)向心關(guān)節(jié)軸承和自潤滑向心關(guān)節(jié)軸承。

潤滑型(鋼對鋼)向心關(guān)節(jié)軸承滑動表面一般經(jīng)過淬火，磷化和涂敷二硫化鉬，具有耐磨損、抗腐蝕的特點。這種軸承在正常情況下，周期性潤滑是必須的。由于滑動表面具有很高的強度，這種軸承特別適合于承受交變重載、沖擊載荷和靜態(tài)重載。

The radial jointbearing is composed of anouter ring withan inner spherical surfaceandan inner ring with anouter spherical surface, forming a pair of sliding friction components.It is mainly used in mechanical mechanisms where the concentricity requirementsare not high, the working surface pressureislarge,and low-speed oscillation,inclinationorrotationmovementsneedtobeperformed. Thesliding frictioncomponentsof the radial jointbearing canbemadeof differentmaterials,mainly including two types: lubricated type (steel onsteel) radialjointbearingsand self-lubricating radial joint bearings.

The sliding surfaces of the lubricated (steel-on-steel) radial joint bearings are generally hardened, phosphatedand coated with molybdenum disulfide,featuring wear resistance and corrosion resistance. Under normal circumstances, periodic lubrication is necessary for these bearings. Due to the high strength of the sliding surfaces,these bearingsare particularly suitable for withstanding alternating heavyloads,impactloadsandstaticheavyloads.
