RF139減速機(jī)潤(rùn)滑油型號(hào):

RF139減速機(jī)特殊應(yīng)用場(chǎng)合必須使用特殊潤(rùn)滑油,比如要求長(zhǎng)使用壽命潤(rùn)滑油。若需要可提供用于食品行業(yè)和生物降解潤(rùn)滑油。

RF139減速機(jī)潤(rùn)滑油加注量,具體值根據(jù)級(jí)數(shù)與傳動(dòng)比的不同而各異。請(qǐng)您在加注潤(rùn)滑油時(shí)一定注意油位螺栓所指示的精確油量。本頁(yè)附件中的RF139減速機(jī)選型樣本中列出了安裝位置從M1到M6RF139減速機(jī)相應(yīng)的潤(rùn)滑油加注標(biāo)準(zhǔn),請(qǐng)自行下載查看。

RF139減速機(jī)某些安裝位置發(fā)生攪油損失的機(jī)會(huì)較高。出現(xiàn)下列情況時(shí)請(qǐng)與BOSERL公司進(jìn)行聯(lián)系:若無(wú)特殊規(guī)定,BOSERL公司發(fā)貨時(shí)會(huì)根據(jù)RF139減速機(jī)的安裝位置給驅(qū)動(dòng)裝置加潤(rùn)滑油,因此應(yīng)在訂貨時(shí)指定安裝位置(M1…M6,參見(jiàn)“RF139減速機(jī)說(shuō)明書中的安裝位置與訂貨說(shuō)明”章節(jié))。若之后對(duì)安裝位置需要改動(dòng),則加潤(rùn)滑油必須與安裝位置相符(潤(rùn)滑油加注量)。RF系列減速機(jī)

RF139減速機(jī)使用說(shuō)明:

RF139減速機(jī)的螺母:立式安裝RF139減速機(jī)輸出法蘭直徑450螺母規(guī)格M16;立式安裝RF139減速機(jī)輸出法蘭直徑550螺母規(guī)格M16;RF139減速機(jī)螺母/螺母擰緊扭矩強(qiáng)度等級(jí)10.9。齒輪減速電機(jī)

RF139減速機(jī)危險(xiǎn)使用說(shuō)明:驅(qū)動(dòng)裝置意外啟動(dòng)會(huì)造成擠傷,可能造成重傷或死亡;開(kāi)始工作前,應(yīng)先斷開(kāi)減速電機(jī)的電源并且采取措施防止意外接通!

RF139減速機(jī)警告說(shuō)明:由于RF139減速機(jī)發(fā)熱或RF139減速機(jī)油溫過(guò)高可能引起燙傷;對(duì)RF139減速機(jī)進(jìn)行操作前先冷卻;擰出油位檢查螺栓和放油螺栓時(shí)要格外小心。

RF139減速機(jī)注意事項(xiàng):若未注入正確的RF139減速機(jī)油則可能造成潤(rùn)滑油性能失效,可能造成財(cái)產(chǎn)損失;合成潤(rùn)滑油不可能相互混用并不可與礦物潤(rùn)滑油混用;礦物油用作標(biāo)準(zhǔn)的潤(rùn)滑油,不能用于特殊行業(yè)。

RF139減速機(jī)提示事項(xiàng):油位檢查螺栓、放油螺栓、以及透氣閥的位置在安裝位置上,要參見(jiàn)RF139減速機(jī)說(shuō)明書安裝位置章節(jié)中的內(nèi)容。立式減速機(jī)
