新聞資訊 >> 簡(jiǎn)述蝸輪蝸桿減速機(jī)的蝸輪齒形變化故障-

診斷因蝸輪齒形變化引起的蝸輪蝸桿減速機(jī)故障設(shè)計(jì)了一種減速機(jī)振動(dòng)信號(hào)采集系統(tǒng)。同時(shí)為了從振動(dòng)信號(hào)中提取出故障信號(hào)的特征頻率提出了經(jīng)驗(yàn)?zāi)B(tài)分解與希爾伯特變換相結(jié)合的方法；對(duì)正常和有故障兩種蝸輪進(jìn)行的振動(dòng)測(cè)試對(duì)比實(shí)驗(yàn)結(jié)果表明該方法所得結(jié)果與利用齒輪測(cè)量?jī)x測(cè)量結(jié)果相同證實(shí)了該方法診斷蝸輪蝸桿減速機(jī)由蝸輪齒形變化故障的有效性。

蝸輪蝸桿減速機(jī)具有傳動(dòng)比大輸出轉(zhuǎn)矩大的特點(diǎn)被廣泛應(yīng)用在各式機(jī)械的傳動(dòng)系統(tǒng)中，由于工作環(huán)境差減速機(jī)中蝸輪容易受到損害和出現(xiàn)故障而蝸輪失效是誘發(fā)減速機(jī)故障的重要原因其中齒形變化是導(dǎo)致蝸輪失效的一個(gè)重要因素。一旦減速機(jī)發(fā)生故障將會(huì)導(dǎo)致意外事故造成經(jīng)濟(jì)損失對(duì)于大型機(jī)械來(lái)說(shuō)停機(jī)維修損失更大，因此迫切需要研究一種有效診斷減速機(jī)蝸輪齒形變化故障的方法實(shí)時(shí)監(jiān)測(cè)減速機(jī)的工作狀況及時(shí)發(fā)現(xiàn)問(wèn)題及時(shí)維修降低經(jīng)濟(jì)損失。

上海諾廣生產(chǎn)RV25/RV30/RV40\RV50\RV63/RV75/RV90/RV110/RV130及RV150蝸輪蝸桿減速機(jī)。本公司還生產(chǎn)其他系列WB擺線針輪減速機(jī)、MB無(wú)級(jí)變速機(jī)、SWL絲桿升降機(jī)等更多系列減速機(jī)。詳細(xì)選型資訊可以訪問(wèn)網(wǎng)站：http://m.pipe22.cn/html/product/27.html。也可以撥打公司熱線：021-63731858或手機(jī)：18939701298/18939766978
