磁粉制动器是根据电磁原理传递转矩的

  磁(ci)粉制动器是根据电磁原理和(he)利用(yong)磁粉(fen)传递(di)转矩的,磁粉(fen)制动器和(he)磁粉(fen)离合(he)器是利用新(xin)的材料(liao)和制(zhi)造,成为(wei)改进设备的选择,磁粉制(zhi)动器在同(tong)滑差(cha)无关的情况(kuang)下能够传递(di)一(yi)定的转矩,具有响应速度 快、结构简单(dan)、无污(wu)染(ran)、无噪音、无冲击振动节(jie)约(yue)能源(yuan)等优点。是一(yi)种多(duo)用途、性(xing)能优越的自(zi)动控制(zhi)元件。
  磁(ci)(ci)粉制(zhi)(zhi)(zhi)动(dong)(dong)器(qi)(qi)(qi)还经常被用(yong)于传动(dong)(dong)机(ji)械的测功(gong)加载和制(zhi)(zhi)(zhi)动(dong)(dong)等,大卷(juan)绕(rao)半径(jing)的乘积应不超过(guo)制(zhi)(zhi)(zhi)动(dong)(dong)器(qi)(qi)(qi)的额定转矩(ju)(ju),磁(ci)(ci)粉制(zhi)(zhi)(zhi)动(dong)(dong)器(qi)(qi)(qi)广泛应用(yong)于印刷、包(bao)装(zhuang)、造纸及纸品加工、纺织、印刷、电线、电缆、橡胶皮革、金属箔带加工等有关卷(juan)取装(zhuang)置的张力(li)自动(dong)(dong)控(kong)制(zhi)(zhi)(zhi)系(xi)统中,磁(ci)(ci)粉制(zhi)(zhi)(zhi)动(dong)(dong)器(qi)(qi)(qi)还可作为模拟加载器(qi)(qi)(qi)使用(yong),激(ji)磁(ci)(ci)电流(liu)与转矩(ju)(ju)基本成线性关系(xi)通(tong)过(guo)调节(jie)激(ji)磁(ci)(ci)电流(liu)可以控(kong)制(zhi)(zhi)(zhi)力(li)矩(ju)(ju)的大小。
  磁(ci)粉(fen)制动器(qi)的选型一(yi)般以其**制(zhi)动(dong)(dong)(dong)转矩(ju)(ju)(ju)来确定,磁(ci)(ci)(ci)粉(fen)制(zhi)动(dong)(dong)(dong)器力(li)矩(ju)(ju)(ju)与转速无关,保持定值,静力(li)矩(ju)(ju)(ju)和动(dong)(dong)(dong)力(li)矩(ju)(ju)(ju)没有(you)差(cha)别(bie),磁(ci)(ci)(ci)粉(fen)制(zhi)动(dong)(dong)(dong)器的允许(xu)滑(hua)差(cha)功(gong)率,在(zai)散热(re)条件一(yi)定时,是定值,其连续运行(xing)时,磁(ci)(ci)(ci)粉(fen)制(zhi)动(dong)(dong)(dong)器实际滑(hua)差(cha)需在(zai)允许(xu)滑(hua)差(cha)功(gong)率以内,使(shi)(shi)(shi)用转速高时,需降低力(li)矩(ju)(ju)(ju)使(shi)(shi)(shi)用,磁(ci)(ci)(ci)粉(fen)制(zhi)动(dong)(dong)(dong)器在(zai)运输过程中,常使(shi)(shi)(shi)磁(ci)(ci)(ci)粉(fen)聚集到(dao)某处(chu)甚(shen)至会出(chu)现“卡死”现象,此(ci)时只需将制(zhi)动(dong)(dong)(dong)器整体翻动(dong)(dong)(dong),使(shi)(shi)(shi)磁(ci)(ci)(ci)粉(fen)松散开来,或用杠杆撬动(dong)(dong)(dong)。
