JZM type diaphragm coupling
TAG
JZM型膜片联轴器是由几组膜片(不锈钢薄扳)用螺栓交错地与两半联轴器联接,每组膜片由数片叠集而成,膜片分为连杆式和不同形状的整片式。
JZM typeDiaphragm coupling靠膜片的弹性变形来补偿所联两轴的相对位移,不用润滑,结构较紧凑,使用寿命长,无旋转间隙,不受温度和油污影响,具有耐酸、耐碱、_的特点,适用于高温、高速、有腐蚀介质工况环境的轴系传动,广泛用于各种机械装置的轴系传动,如水泵(尤其是大功率、化工泵)、风机、压缩机、液压机械、石油机械、印刷机械、纺织机械、化工机械、矿山机械、冶金机械、航空(直升飞机)、舰艇高速动力传动系统,经动平衡后应用于高速传动轴系已比较普遍。
JZM型膜片联轴器具承载能力大、质量轻、结构尺寸小,传动效率和传动精度高、装拆方便,且具有无相对滑动,不需润滑,使用寿命长、无噪声、耐酸等特点,可用于高温、低温和有油、有水和腐蚀介质的工况环境。适用于中、高速、大转矩轴系传动。以及各种机械装置载荷变化不大的轴系传动,通用性强。
正确安装螺栓方法:
Insert the bolt from the outside of the small hole in the flange, and then pass it into the diaphragm hole (pay attention to the direction of the diaphragm, the diaphragm is composed of many single sheets, rivets and rivet washers, the rivet washers should be in contact with the buffer sleeve, otherwise It will affect the service life of the rivet set), and then insert the buffer sleeve, elastic washer, and tighten the nut from the outside of the large hole of the flange, so that the bolt does not rotate, because the bolt and the flange match section The surface is a very important part of the torque transmission, and the integrity of the surface directly affects the performance.
螺栓配合段与法兰盘小孔配合段间隙,一般根据螺栓直径为0.20mm~0.30mm此配合段起到传递扭矩非常关键的作用,如果间隙超标更换。
缓冲套与膜片铆钉内孔与螺栓直径间隙为0.5mm~0.7mm,起到压紧和定位膜片作用。
如果螺栓方向装锴容易造成螺栓偏斜,而膜片会因此而扭曲变形。
因此,在安装螺栓时要注意螺栓方向,不要随意安装螺栓方向,否则会造成膜片扭曲,长期运转会使膜片和螺栓配合段表面、半轴节小孔处的损坏。
