1裝有滾動(dòng)軸承軸承箱一般隨轉(zhuǎn)子組裝出廠,但在運(yùn)輸過程中軸承
與密封端蓋等間隙產(chǎn)生移位,在安裝時(shí)必須按圖紙尺寸進(jìn)行調(diào)整,這
項(xiàng)工作必須在地腳螺栓灌漿之前進(jìn)行。目前我公司F式滾動(dòng)軸承轉(zhuǎn)子
組軸承箱配置如附圖(一)中表一所示。對(duì)于高溫風(fēng)機(jī)的傳動(dòng)組代號(hào)在

2滾動(dòng)軸潤(rùn)滑和冷卻方式
滾動(dòng)軸承箱注油量達(dá)到油標(biāo)中線以上時(shí),軸承有一部分滾柱浸在潤(rùn)
滑油里,軸承箱里還設(shè)有帶油環(huán),當(dāng)風(fēng)機(jī)主軸轉(zhuǎn)動(dòng)時(shí)軸承滾柱和帶油
環(huán)使?jié)櫥彤a(chǎn)生大量的飛濺,軸承得到充分的潤(rùn)滑。軸承的冷卻是通
過軸承座軸承孔外圈水道循環(huán)水帶走軸承運(yùn)行時(shí)的熱量。冷卻水在
20℃時(shí)供水量大于lm3/h,水壓小于或等于0.4Mpa.
3軸承箱端蓋軸封為迷宮式結(jié)構(gòu),在其下部設(shè)有回油孔,在安裝時(shí)
必須保持該孔暢通,且將該孔安裝在端蓋的下方。
4對(duì)于高溫風(fēng)機(jī)的軸承箱結(jié)構(gòu)基本不變,但另設(shè)有稀油站供油的進(jìn)油
裝置和排油孔裝置。供油量的大小由現(xiàn)場(chǎng)根據(jù)軸承的溫升或軸承箱存
潤(rùn)滑油量來控制,最大不能有軸封處漏油,最小軸承溫升不能太高。
因?yàn)檩S承箱內(nèi)的回油是在無動(dòng)力下進(jìn)行的,因此回油必須暢通,并且
盡量利用重力的作用,排油管應(yīng)傾斜或階梯式布置;兩軸承箱回油會(huì)
合進(jìn)稀油站時(shí),管路要加粗,盡量減少排油主力。(排油管的布置如

二、滑動(dòng)軸承的安裝調(diào)試、潤(rùn)滑和冷卻裝置

對(duì)于滑動(dòng)軸承,我公司目前按照潤(rùn)滑方式分為兩種:帶油環(huán)供油
水冷滑動(dòng)軸承和強(qiáng)制供油滑動(dòng)軸承。結(jié)構(gòu)形式見附圖(二)、附圖(三)。
滑動(dòng)軸承軸承箱一般單獨(dú)包裝出廠,在安裝時(shí),與上述滾動(dòng)軸承箱安
裝一樣,按圖紙尺寸進(jìn)行調(diào)整基礎(chǔ)螺栓灌漿凝固后進(jìn)行精確校正主
軸、軸承座;對(duì)兩軸承座對(duì)分面水平度,其不水平度要求軸向W
0.04/1000,橫向不水平度要求不超過W0.08/1000;主軸水平度W
0.04/1000.然后按圖紙檢查軸承體外球面與軸承箱的內(nèi)球面的過盈量
和軸承孔與軸的單面間隙及止推面的單面間隙,如果其間隙不在要求
范圍之內(nèi),可以按圖紙要求進(jìn)行刮研。檢查間隙的方法可以用壓鉛法。
球面內(nèi)過盈量太小可以用墊薄銅板補(bǔ)償。
帶油環(huán)供油水冷滑動(dòng)軸承的潤(rùn)滑,主要靠風(fēng)機(jī)主軸旋轉(zhuǎn)帶動(dòng)帶油
環(huán),把油池里的潤(rùn)滑油帶到軸承內(nèi)形成油膜而工作的,軸承的冷卻靠
軸承體內(nèi)水道并用軟管接出循環(huán)供水冷卻。在安裝水管后應(yīng)進(jìn)行水壓
試驗(yàn),試驗(yàn)水壓應(yīng)在0.4Mpa-0.6Mpa之間,在軸承座內(nèi)不得有漏水現(xiàn)

強(qiáng)制供油滑動(dòng)軸承潤(rùn)滑靠稀油站供油,在兩軸承座進(jìn)油處設(shè)有壓
力表和調(diào)節(jié)閥,控制進(jìn)油壓力和進(jìn)油量,進(jìn)油壓力一般控制在
0.1Mpa-0.25Mpa之間.因?yàn)檩S承箱內(nèi)的排油是在無動(dòng)力下進(jìn)行的,因
此排油管路必須暢通,并且盡量利用重力的作用。排油管應(yīng)傾斜或階
