簡(jiǎn)要描述:德國(guó)HENGSTLER亨士樂(lè)光電編碼器,亦稱光電碼盤(pán)、光電脈沖發(fā)生器、光電脈沖編碼器等,它把機(jī)械轉(zhuǎn)角變成電脈沖,是數(shù)控機(jī)床上常用的種角位移檢測(cè)元件,也可用于角速度檢測(cè)。
德國(guó)HENGSTLER亨士樂(lè)光電編碼器,亦稱光電碼盤(pán)、光電脈沖發(fā)生器、光電脈沖編碼器等,它把機(jī)械轉(zhuǎn)角變成電脈沖,是數(shù)控機(jī)床上常用的種角位移檢測(cè)元件,也可用于角速度檢測(cè)。
德國(guó)HENGSTLER亨士樂(lè)光電編碼器的測(cè)量精度取決于它所能分辨的zui小角度,而這與碼盤(pán)圓周的條紋數(shù)有關(guān),即分辨角α=360°/狹縫數(shù)。如條紋數(shù)為1024,則分辨角α=360°/1024=0.352°。光電編碼器的輸出信號(hào)A、和B、為差動(dòng)信號(hào)。差動(dòng)信號(hào)大大提高了傳輸?shù)目垢蓴_能力。在數(shù)控系統(tǒng)中,常對(duì)上述信號(hào)進(jìn)行倍頻,以進(jìn)步提高分辨力。例如,配置2000脈沖/r光電編碼器的伺服電動(dòng)機(jī)直接驅(qū)動(dòng)8mm螺距的滾珠絲杠,經(jīng)數(shù)控系統(tǒng)4倍頻后,相當(dāng)于8000脈沖/r的角度分辨力,對(duì)應(yīng)工作臺(tái)的直線分辨力由倍頻前的0.004mm提高到0.001mrn。光電式編碼器的優(yōu)點(diǎn)是沒(méi)有接觸磨損,碼盤(pán)壽命長(zhǎng),允許轉(zhuǎn)速高,而且zui外圈每片寬度可做得很小,因而精度高。缺點(diǎn)是結(jié)構(gòu)復(fù)雜,格相對(duì)要高,光源壽命偏短。
