但是，我國(guó)包裝機(jī)械出口額還不足總產(chǎn)值的5%，進(jìn)口額卻與總產(chǎn)值大體相當(dāng)。這說(shuō)明我國(guó)對(duì)包裝機(jī)械的需求缺口很大，國(guó)產(chǎn)包裝機(jī)械與國(guó)外產(chǎn)品相比，科技水平差距仍然較大，遠(yuǎn)遠(yuǎn)滿足不了國(guó)內(nèi)需求。

轉(zhuǎn)子軸承不但價(jià)格昂貴，而且更換十分困難，往往造成停產(chǎn)損失。正確選擇轉(zhuǎn)子軸承的型號(hào)和壽命由于轉(zhuǎn)子軸承的受力十分復(fù)雜，很難用理論公式進(jìn)行計(jì)算，有的教科書(shū)更多用經(jīng)驗(yàn)公式P=3G(G為轉(zhuǎn)子體質(zhì)量)來(lái)計(jì)算當(dāng)量載荷。
