目前的設(shè)計(jì)思路往往是帶有半經(jīng)驗(yàn)性質(zhì),因?yàn)橛行﹩栴}是要經(jīng)過實(shí)踐摸索改進(jìn)。實(shí)際運(yùn)行時(shí)配油盤的運(yùn)轉(zhuǎn)還欠可靠,濟(jì)南鑄造機(jī)械研究所針對(duì)CY14-1型軸向柱塞泵的這種配油盤易燒損的故障,在CY14-1B型泵中設(shè)計(jì)了一種新型配油機(jī)構(gòu)。就是在柱塞腔換向時(shí)易燒損的輔助支承處引入壓力油液,進(jìn)行強(qiáng)制潤(rùn)滑,這樣缸體的盲孔A當(dāng)與B孔接通時(shí),立即充滿壓力油液,進(jìn)行潤(rùn)滑輔助支承,同時(shí)還起一定的靜壓支承作用,減少了燒盤故障。
另外,人們又想到早期的配油機(jī)構(gòu),這一循環(huán)是上升到靜平壓平衡的基礎(chǔ)上,滾動(dòng)體只承受很小一部分載荷。。
