LF/LFE弹片锁紧螺母(轴向锁固)选型表

简述

LF/LFE系列切缝型的精密螺母用于无法使用扳手从径向拧紧螺钉的工况场合。旋转前端面的紧定螺钉激活的轴向强度通过圆锥形楔子施加到带螺纹的弹片上,可实现强大的锁定力。因此,强烈建议将它们用于密闭壳体内部或深腔室中安装轴承和其他部件。LF型有一组(2个)紧定装置,而LFE型则有二组(4个)180°对称紧定装置,固LFE型平衡性更高,转速更高,相同尺寸的锁定力是LF型的两倍。

特征

  • 本体材质:42CrMo锻件
  • 表面处理:非工作面喷砂发黑
  • 调质硬度:HRC28°~32°
  • 螺纹精度:ISO-4H精密车削
  • 平面偏摆:0.002~0.005mm
