盘式制动器的传动应用介绍

来源:http://impnow.com/news/355.html添加时间:2021-07-27

  盘(pan)式制动(dong)器(qi)(qi)由(you)弹(dan)簧加载、液压松(song)闸,对(dui)直线或(huo)旋转运动(dong)提(ti)供安全(quan)可(ke)靠的(de)制动(dong)。制动(dong)器(qi)(qi)由(you)两个(ge)对(dui)称(cheng)部分组成,可(ke)佩或(huo)不配支架。配支架的(de)制动(dong)器(qi)(qi)适用(yong)于标准厚度(du)为(wei)12mm的(de)制动(dong)圆盘(pan),若制动(dong)器(qi)(qi)圆盘(pan)厚度(du)超过标准厚度(du),可(ke)用(yong)带(dai)垫片(pian)(pian)加宽的(de)制动(dong)器(qi)(qi)。制动(dong)器(qi)(qi)每对(dui)称(cheng)部分有两个(ge)圆柱导销,将来自制动(dong)衬(chen)片(pian)(pian)上(shang)(shang)的(de)切向传动(dong)力(li)传递到制动(dong)体和支架上(shang)(shang),因此(ci)制动(dong)器(qi)(qi)活塞不受任何径向力(li)的(de)影响,确保使(shi)用(yong)寿命的(de)增(zeng)长。当压力(li)释放(fang)时(shi),制动(dong)器(qi)(qi)每一对(dui)称(cheng)部分上(shang)(shang)的(de)两个(ge)回位弹(dan)簧使(shi)摩擦衬(chen)片(pian)(pian)脱开(kai)制动(dong)盘(pan)复位。

  为(wei)补偿制动(dong)(dong)衬片(pian)的(de)(de)磨损和保(bao)持满负荷制动(dong)(dong)力,必(bi)须(xu)正确调整蝶(die)形弹簧组。通过调节螺(luo)母(mu)可以对需要进(jin)行调整的(de)(de)伸(shen)缩(suo)活塞进(jin)行简单直观(guan)的(de)(de)调节。作为(wei)可选件,可以安装接近开(kai)(kai)关或机械开(kai)(kai)关显示(shi)制动(dong)(dong)器的(de)(de)开(kai)(kai)/关状(zhuang)态和需要调整时的(de)(de)指示(shi)。

制动器

  盘式制动(dong)器(qi)的传动(dong)应(ying)用为大(da)家列举(ju)了几个较为代表性的行业:

  1.搬运机械行业。像进给机、输(shu)送机、卷(juan)扬机和(he)起重机都使用到了盘式制动器;

  2.事(shi)物(wu)机(ji)械(xie)行业。像电子复写(xie)机(ji)、打印机(ji)和计算机(ji)都使用到(dao)了盘式(shi)制动(dong)器;

  3.机(ji)械行(xing)业(ye)。像(xiang)机(ji)械行(xing)业(ye)中的车床(chuang)、自动CNC床(chuang)和专用(yong)机(ji)等都用(yong)到(dao)了盘式制动器。

  盘式制动(dong)(dong)(dong)(dong)器(qi)按制动(dong)(dong)(dong)(dong)钳(qian)的(de)结(jie)构(gou)型分(fen)固(gu)(gu)定(ding)(ding)卡钳(qian)式和浮动(dong)(dong)(dong)(dong)卡钳(qian)式。固(gu)(gu)定(ding)(ding)卡钳(qian)式即(ji)制动(dong)(dong)(dong)(dong)钳(qian)固(gu)(gu)定(ding)(ding)不(bu)动(dong)(dong)(dong)(dong),制动(dong)(dong)(dong)(dong)盘两(liang)(liang)侧均(jun)有油(you)(you)缸(gang)。制动(dong)(dong)(dong)(dong)时仅(jin)两(liang)(liang)侧油(you)(you)缸(gang)中的(de)活(huo)塞驱使两(liang)(liang)侧制动(dong)(dong)(dong)(dong)块作相向(xiang)移动(dong)(dong)(dong)(dong)。常(chang)(chang)开固(gu)(gu)定(ding)(ding)卡钳(qian)式,摩擦(ca)块底板通(tong)过销轴(zhou)和平(ping)行(xing)(xing)杠杆组固(gu)(gu)定(ding)(ding)在基(ji)架上(shang)。弹簧使制动(dong)(dong)(dong)(dong)器(qi)常(chang)(chang)开。制动(dong)(dong)(dong)(dong)时,将液(ye)压油(you)(you)通(tong)入油(you)(you)缸(gang),同(tong)时压缩弹簧而紧闸。平(ping)行(xing)(xing)杠杆组能使摩擦(ca)元件与制动(dong)(dong)(dong)(dong)盘保持平(ping)行(xing)(xing)。
