行星減速機(jī)靜密封點(diǎn)確?；赜褪柰?br>
精密行星減速機(jī)的輸人軸、輸出軸與殼體軸承端面兩個(gè)相對(duì)運(yùn)動(dòng)的聯(lián)系面之間的密封稱為動(dòng)密封點(diǎn),減速機(jī)上下殼體端面及其它構(gòu)造性聯(lián)接面的密封稱為靜密封點(diǎn),動(dòng)靜密封點(diǎn)的密封失效使之變成走漏點(diǎn)。咱們從構(gòu)造上作進(jìn)一步剖析,就可以找到密封失效的緣由。從而為處理走漏疑問奠定根底。
X、ZX系列行星減速機(jī)
在行星減速機(jī)下殼體放軸承方位處,沿殼體從端蓋槽讓出一點(diǎn)間隔向里方向,由淺漸深,寬度約5~擺布的導(dǎo)油槽,這是確?；赜褪柰?減小密封點(diǎn)壓差的重要一步。在擋油環(huán)外側(cè)制造裝置甩油環(huán),甩油環(huán)內(nèi)徑與軸承內(nèi)徑一樣,與軸靜配合,外徑比端蓋內(nèi)徑小1~擺布。若甩油環(huán)選用迷宮式甩油環(huán),一起將端蓋加工與之相配套,則作用更佳。甩油環(huán)擋住了由軸面外滲的潤滑油,并經(jīng)導(dǎo)油槽回到下殼體中。

關(guān)于步進(jìn)電機(jī)和交流伺服電機(jī)的性能有較大差別。
步進(jìn)電機(jī)是一種離散運(yùn)動(dòng)的裝置，它和現(xiàn)代數(shù)字控制技術(shù)有著本質(zhì)的聯(lián)系。在目前國內(nèi)的數(shù)字控制系統(tǒng)中，步進(jìn)電機(jī)的應(yīng)用十分廣泛。隨著全數(shù)字式交流伺服系統(tǒng)的出現(xiàn)，交流伺服電機(jī)也越來越多地應(yīng)用于數(shù)字控制系統(tǒng)中。為了適應(yīng)數(shù)字控制的發(fā)展趨勢，運(yùn)動(dòng)控制系統(tǒng)中大多采用步進(jìn)電機(jī)或全數(shù)字式交流伺服電機(jī)作為執(zhí)行電動(dòng)機(jī)。
雖然兩者在控制方式上相似（脈沖串和方向信號(hào)），但在使用性能和應(yīng)用場合上存在著較大的差異。如：1、制精度不同；2、低頻特性不同 3、矩頻特性不同 4、過載能力不同 5、運(yùn)行性能不同 6、速度響應(yīng)性能不同。
交流伺服系統(tǒng)在許多性能方面都優(yōu)于步進(jìn)電機(jī)。但在一些要求不高的場合也經(jīng)常用步進(jìn)電機(jī)來做執(zhí)行電動(dòng)機(jī)。所以，在控制系統(tǒng)的設(shè)計(jì)過程中要綜合考慮控制要求、成本等多方面的因素，選用適當(dāng)?shù)目刂齐姍C(jī)。
