自锁螺母与紧锁螺母区别

在介绍自锁螺母与紧锁螺母区别之前,我们先来来接以下关于螺母的工作原理:

Before introduced since the lock nut and lock nut distinction, let's come to the following about the working principle of nut:

      螺母的工作原理是采用螺母和螺栓之间的摩擦力进行自锁的。但是在动载荷中这种自锁的可靠性就会降低。在一些重要的场合我们就会采取一些防松措施,保证螺母锁紧的可靠性。其中用锁紧螺母就是其中的一种防松措施。

Working principle of the nut is using self-locking of friction between the nut and bolt. But in the dynamic load will reduce the reliability of the self-locking. In some important occasions we will take some prevention measures, to ensure the reliability of the nut lock. Among them with the lock nut is a locking measure among them.

      什么是自锁螺母?

      自锁螺母的功能主要是防松、抗振。用于特殊场合。锁紧螺母跟自锁螺母是一个概念,带自锁功能的螺母就叫锁紧螺母。拧入力矩及拧出力矩有相关的标准,可参考机械设计手册或国家螺母标准。

What is a self-locking nuts?

The function of self-locking nut mainly locking, resistant to vibration. For special occasions. Lock nut with self-locking nut is a concept, nut with self-locking function call lock nut. Screw in torque and twist moment to have the relevant standards, can refer to the manual mechanical design or nut standards of the state.

      什么是紧锁螺母?

      锁紧螺母一般有两种,一种是用两个一样的螺母拧在同一支螺栓上,在两个螺母之间附加一个拧紧力矩,使得螺栓连接可靠;另一种是专用的防松螺母,需要和一种可以防松垫片一起使用。

What is the lock nut?

Lock nut there are generally two kinds, one kind is to use the same two nut screw with a bolt, attach a tightening torque between two nut, the bolt connection is reliable; The other is a dedicated locknut, needs and a locking washers are used together.

      而专用的防松螺母不是六角螺母,而是一中圆螺母,在螺母的圆周上开有6个缺口,这六个缺口既是拧紧工具的着力点,又是防松垫片卡口的卡入处。 第二种防松方式比第一种更可靠,但是结构相对复杂。

And special locknut is not a hexagonal nut, but one round nut, there are six in the nut on the circumference of a circle of gap, the six gap is the focus of tighten tools, and locking washers bayonet card into place. The second mode of locking more reliable than the first one, but the structure is relatively complex.
