磁粉制動器所(suo)用制動(dong)件(jian)(jian)的(de)(de)(de)(de)功能會(hui)影響制動(dong)進程(cheng)嗎?在(zai)張力(li)控制系統中起(qi)(qi)到啥(sha)效果呢?今天磁(ci)粉(fen)(fen)制動(dong)器廠(chang)家來(lai)給我(wo)們簡略論(lun)述下(xia):磁(ci)粉(fen)(fen)制動(dong)器是接(jie)(jie)收磁(ci)粉(fen)(fen)作介質(zhi),在(zai)通(tong)(tong)電(dian)環境(jing)下(xia)構成磁(ci)粉(fen)(fen)鏈來(lai)傳(chuan)達(da)。當(dang)(dang)線(xian)扭矩(ju)(ju)的(de)(de)(de)(de)新式傳(chuan)動(dong)元件(jian)(jian),嚴重由(you)(you)內轉(zhuan)子(zi)(zi)(zi)、外轉(zhuan)子(zi)(zi)(zi)、激(ji)磁(ci)線(xian)圈及磁(ci)粉(fen)(fen)組成。 粉(fen)(fen)與(yu)從動(dong)轉(zhuan)子(zi)(zi)(zi)之間沒有交兵,自動(dong)轉(zhuan)子(zi)(zi)(zi)空轉(zhuan)。制動(dong)扭矩(ju)(ju)的(de)(de)(de)(de)意圖。特色圈不通(tong)(tong)電(dian)時,自動(dong)轉(zhuan)子(zi)(zi)(zi)旋轉(zhuan),由(you)(you)于離心力(li)的(de)(de)(de)(de)效果,磁(ci)粉(fen)(fen)被(bei)甩在(zai)自動(dong)轉(zhuan)子(zi)(zi)(zi)的(de)(de)(de)(de)內壁(bi)上,磁(ci)接(jie)(jie)通(tong)(tong)直流電(dian)源后孕(yun)育發生(sheng)電(dian)磁(ci)場(chang), 工作介質(zhi)磁(ci)粉(fen)(fen)在(zai)磁(ci)力(li)線(xian)效果下(xia)構成磁(ci)粉(fen)(fen)鏈,把內轉(zhuan)子(zi)(zi)(zi)、外轉(zhuan)子(zi)(zi)(zi)聯接(jie)(jie)起(qi)(qi)來(lai),然后抵(di)達(da)傳(chuan). 合離頻(pin)繁(fan),相應速度(du)快,頻(pin)率高,每(mei)分鐘線(xian)性度(du)好, 輸出轉(zhuan)矩(ju)(ju)恒、功率 、過載保(bao)可(ke)抵(di)達(da)40-60次,可(ke)遍(bian)及應用于疾速事景況態和高頻(pin)率場(chang)所(suo)。 矩(ju)(ju)與(yu)激(ji)磁(ci)電(dian)流在(zai)適(shi)當(dang)(dang)遍(bian)及的(de)(de)(de)(de)領域內成正比(bi), 可(ke)以作線(xian)性調節元件(jian)(jian)定,由(you)(you)于轉(zhuan)矩(ju)(ju)的(de)(de)(de)(de)巨細只是取決于激(ji)磁(ci)電(dian)流的(de)(de)(de)(de)巨細,而與(yu)滑差(cha)速度(du)無關。
磁粉制動器嚴(yan)(yan)重與(yu)系列電(dian)機(ji)配套。磁(ci)(ci)粉制(zhi)(zhi)動(dong)(dong)(dong)器遍及應用于冶(ye)金(jin)、構筑、化工、食物、機(ji)床、舞(wu)臺(tai)、電(dian)梯、輪船(chuan)、包裝等(deng)(deng)板(ban)滯(zhi)中(zhong),以及在斷電(dian)時制(zhi)(zhi)動(dong)(dong)(dong)等(deng)(deng)場所。使磁(ci)(ci)粉制(zhi)(zhi)動(dong)(dong)(dong)器的板(ban)滯(zhi)工作(zuo)部件阻(zu)止或減(jian)速所有必要施加(jia)的阻(zu)力矩稱為制(zhi)(zhi)動(dong)(dong)(dong)力矩。制(zhi)(zhi)動(dong)(dong)(dong)力矩是方案、選用磁(ci)(ci)粉制(zhi)(zhi)動(dong)(dong)(dong)器的根(gen)據,其巨細由板(ban)滯(zhi)的型(xing)式和工作(zuo)需(xu)求決議。磁(ci)(ci)粉制(zhi)(zhi)動(dong)(dong)(dong)器上所用沖(chong)突(tu)材(cai)料(制(zhi)(zhi)動(dong)(dong)(dong)件)的功能直接影(ying)響制(zhi)(zhi)動(dong)(dong)(dong)進(jin)程,而(er)影(ying)響磁(ci)(ci)粉制(zhi)(zhi)動(dong)(dong)(dong)器功能的嚴(yan)(yan)重要素為工作(zuo)溫(wen)度和溫(wen)升速度。沖(chong)突(tu)材(cai)料應具有高而(er)安定的沖(chong)突(tu)系數和杰出的耐(nai)磨性。沖(chong)突(tu)材(cai)料分金(jin)屬(shu)和非金(jin)屬(shu)兩類。前者常用的有鑄鐵(tie)、鋼、青銅和粉末冶(ye)金(jin)沖(chong)突(tu)材(cai)料等(deng)(deng),后者有皮(pi)革、橡膠、木材(cai)和石棉等(deng)(deng)。
