style="text-indent:25px">對(duì)于很多人來說買了伺服電機(jī)之后，安裝就成了一個(gè)大問題。許多人在安裝時(shí)如果不注意，很容易產(chǎn)生各種問題。因此，現(xiàn)在特地來分享一下在安裝伺服電機(jī)時(shí)需要注意的問題。在使用時(shí)，我們可以更清晰。首先，伺服電機(jī)雖然本身具有較高的防護(hù)等級(jí)，但不適合安裝在多油、潮濕的地方。但長時(shí)間處于多水、或多油的環(huán)境中，終究對(duì)電機(jī)的壽命不利。安裝之前需要用到它。在安裝過程中有幾點(diǎn)需要了解。1.若伺服電機(jī)與減速機(jī)相連，則在使用伺服電機(jī)時(shí)應(yīng)加油封，以防減速機(jī)的油進(jìn)入伺服電機(jī)。2.確保電纜不受外界彎曲力或其本身重量所造成的力矩或垂直載荷，特別是在電纜出口或連接處。3.要保證每一臺(tái)伺服電機(jī)安裝和運(yùn)行時(shí)，其徑向和軸向負(fù)荷都控制在規(guī)定的數(shù)值之內(nèi)。4.當(dāng)伺服電機(jī)的軸端安裝/拆卸耦合部件(聯(lián)軸器、皮帶輪、鏈輪等)時(shí)，不要用錘子直接敲擊。伺服電機(jī)是一種常用的電機(jī)，用于各種高技術(shù)裝備。</p><div

style="text-indent:25px">對(duì)伺服電機(jī)減速機(jī)故障進(jìn)行分析的常用方法是，首先要查清故障產(chǎn)生的主要特征，尤其是故障發(fā)展過程中產(chǎn)生的各種痕跡，再由痕跡分析損傷零件的受力關(guān)系，找出產(chǎn)生異常力的原因，或者由故障特征聯(lián)系相關(guān)部件的結(jié)構(gòu)特點(diǎn)進(jìn)行分析，就可以達(dá)到弄懂故障根源的目的。如，由減速機(jī)斷口特征分析零件的斷裂原因：伺服電機(jī)減速機(jī)的斷口是指零件斷裂后形成的自然表面。斷口的分析是指直接由人的視覺，或者借助放大鏡觀察零件斷口的特征，根據(jù)這些特征，定性地判斷零件發(fā)生斷裂故障的原因，從而為排除故障運(yùn)行的維修設(shè)計(jì)提供重要依據(jù)。伺服電機(jī)：當(dāng)單相勵(lì)磁時(shí)，在電動(dòng)機(jī)運(yùn)行范圍0。浙江安川電機(jī)品牌哪家好</p><p style="text-indent:25px">交流伺服電機(jī)的工作電壓更高，因此扭矩也更大，精度也更高，同時(shí)能完全按照應(yīng)用場(chǎng)景的要求進(jìn)行控制。浙江安川電機(jī)品牌哪家好</p><p style="text-indent:25px">導(dǎo)軌和絲杠的轉(zhuǎn)動(dòng)慣量對(duì)伺服電機(jī)傳動(dòng)系統(tǒng)的剛性影響很大，固定增益下，轉(zhuǎn)動(dòng)慣量越大，剛性越大，越易引起電機(jī)抖動(dòng)；轉(zhuǎn)動(dòng)慣量越小，剛性越小，電機(jī)越不易抖動(dòng)?？赏ㄟ^更換較小直徑的導(dǎo)軌和絲桿減小轉(zhuǎn)動(dòng)慣量從而減小負(fù)載慣量來達(dá)到電機(jī)不抖動(dòng)。我們知道通常在伺服系統(tǒng)選型時(shí)，除考慮電機(jī)的扭矩和額定速度等等參數(shù)外，我們還需要先計(jì)算得知機(jī)械系統(tǒng)換算到電機(jī)軸的慣量，再根據(jù)機(jī)械的實(shí)際動(dòng)作要求及加工件質(zhì)量要求來具體選擇具有合適慣量大小的電機(jī)。在調(diào)試時(shí)（手動(dòng)模式下），正確設(shè)定慣量比參數(shù)是充分發(fā)揮機(jī)械及伺服系統(tǒng)較佳效能的前提。浙江安川電機(jī)品牌哪家好</p></p><br
