減速機(jī)拆卸與裝配
拆卸:
仔細(xì)觀察減速器外面各部分的結(jié)構(gòu),從觀察中思考以下問題:
1、如何保證廂體支撐具有足夠的剛度
2、軸承座兩側(cè)的上下廂體連接螺栓應(yīng)如何布置
3、支撐該螺栓的凸臺(tái)高度應(yīng)如何確定
4、如何減輕廂體的重量和減少廂體的加工面積
5、減速機(jī)的附件如吊鉤,定位銷釘,啟蓋螺釘油標(biāo),油塞,觀察孔和通氣等各起何作用 其結(jié)構(gòu)如何 應(yīng)如何合理布置
用扳手拆下觀察孔蓋板,考慮觀察孔位置是否妥當(dāng),大小是否合適.

3.驅(qū)動(dòng)器細(xì)分有什么優(yōu)點(diǎn),為什么一定建議我使用細(xì)分功能? 驅(qū)動(dòng)器細(xì)分后的主要優(yōu)點(diǎn)為:?完全消除了電機(jī)的低頻振蕩。低頻振蕩是步進(jìn)電機(jī)(尤其是反應(yīng)式電機(jī))的固有特性,而細(xì)分是消除它的途徑,如果您的步進(jìn)電機(jī)有時(shí)要在共振區(qū)工作(如走圓弧),選擇細(xì)分驅(qū)動(dòng)器是的選擇。?提高了電機(jī)的輸出轉(zhuǎn)矩。尤其是對(duì)三相反應(yīng)式電機(jī),其力矩比不細(xì)分時(shí)提高約30-40%。?提高了電機(jī)的分辨率。由于減小了步距角、提高了步距的均勻度,‘提高電機(jī)的分辨率’是不言而喻的。以上這些優(yōu)點(diǎn),尤其是在性能上的優(yōu)點(diǎn),并不是一個(gè)量的變化,而是質(zhì)的飛躍。根據(jù)我們的記錄,原來使用不細(xì)分驅(qū)動(dòng)器的用戶通過比較后,大都改選為細(xì)分驅(qū)動(dòng)器。所以我們建議您選用細(xì)分驅(qū)動(dòng)器。
4.何為混合式步進(jìn)電機(jī),何為反應(yīng)式步進(jìn)電機(jī),兩者有何區(qū)別?在結(jié)構(gòu)和材料上不同,反應(yīng)式電機(jī)不象混合式電機(jī)那樣內(nèi)部具有磁性材料,故反應(yīng)式電機(jī)沒有自阻,而混合式電機(jī)有自阻(即在電機(jī)未加電的情況下有一定的自鎖力)。?在運(yùn)行性能上有差別,混合式電機(jī)運(yùn)行時(shí)相對(duì)較平穩(wěn),輸出力矩相對(duì)較大,運(yùn)行聲音小。兩種電機(jī)在價(jià)格上有差別,反應(yīng)式電機(jī)比混合式電機(jī)相對(duì)便宜。

非標(biāo)減速機(jī)的主要特點(diǎn)是具有反向自鎖功能,可以有較大的減速比,輸入軸和輸出軸不在同一軸線上,也不在同一平面上。但是一般體積較大,傳動(dòng)效率不高,精度不高;所以非標(biāo)減速機(jī)需要進(jìn)行日常的保養(yǎng)??梢詮南旅鎺讉€(gè)方面進(jìn)行,我們一起看看吧:
1、非標(biāo)減速機(jī)開機(jī)前檢查減速機(jī)內(nèi)油面是否符合要求。按提示打開或換上通氣帽使之通氣順暢,并檢查轉(zhuǎn)動(dòng)是否靈活。
2、非標(biāo)減速機(jī)負(fù)載試車前要空載運(yùn)行半小時(shí)左右,確認(rèn)空載無故障后可加載運(yùn)行。試車應(yīng)經(jīng)常檢查運(yùn)轉(zhuǎn)情況:不得有異常沖擊、振動(dòng)、不得滲、漏油。溫升不得超過60℃,油溫不得超過100℃(日常工作時(shí)也應(yīng)時(shí)行檢查)一切正常方可正式工作。
3、非標(biāo)減速機(jī)在工作中發(fā)現(xiàn)異常情況應(yīng)停機(jī)檢查,查明、排除故障后方可繼續(xù)工作。時(shí)常檢查潤(rùn)滑情情況,注意補(bǔ)足油量,及時(shí)更換變質(zhì)潤(rùn)滑油。
