風(fēng)機(jī)主軸是連接風(fēng)機(jī)風(fēng)翅與風(fēng)機(jī)底座的重要部件,無錫風(fēng)力風(fēng)機(jī)制造有限公司風(fēng)機(jī)主軸是中空的,風(fēng)機(jī)主軸的材質(zhì)是不銹鋼的,內(nèi)孔加工比較困難,現(xiàn)在對風(fēng)機(jī)主軸的加工設(shè)備是深孔鉆鏜床,根據(jù)風(fēng)機(jī)主軸的特性,深孔鉆鏜床要加高床頭。 風(fēng)力發(fā)電機(jī)的主軸既有徑向偏移,又有軸向偏移。實(shí)際上,主軸的軸向偏移直接傳遞到齒輪箱的輸入軸。除非對調(diào)心滾子軸承的徑向游隙,軸向游隙控制以及行星輪的定位做特別處理,否則軸向的偏移會(huì)對齒輪箱里行星架支撐軸承產(chǎn)生不利的影響。主軸的軸向偏移取決于系統(tǒng)的剛性和固定端軸承的內(nèi)部游隙。在固定端使用預(yù)緊的雙列圓錐滾子軸承后,主軸右端的軸向偏移幾乎比使用調(diào)心滾子軸承時(shí)減少4倍。減小軸向偏移可以減小軸向擠壓齒輪箱輸入軸的風(fēng)險(xiǎn),這非常重要。(圖/文http://www.williamslock.com/) (中譯英) Fan shaft is connected with fan fin and fan base of important parts, fan shaft is hollow, the fan spindle is made of stainless steel, inner hole processing more difficult, now on the fan shaft processing equipment is deep hole boring machine, according to the characteristics of the wind machine spindle deep hole boring, heightening the bedside. Main shaft of wind power generator with radial deviation, and the axial offset. In fact, the spindle is axially offset are passed directly to the input shaft of the gear box. Unless the self-aligning roller bearing radial clearance, axial clearance control and planetary wheel positioning for special treatment, or axial offset on the gear box planetary frame supporting bearing adverse impact. The spindle is axially offset depends on system of rigid and fixed end bearing internal clearance. In the fixed end use preload double row tapered roller bearing, spindle right end axial displacement than the use of spherical roller bearing is almost4 times less. Decreasing axial shift axial extrusion can reduce the input shaft of the gear box of the risk, this is very important. |
