Let me give you a simple example to illustrate the application of spring washer in actual use:
This one in the picture is my first screw assembly. Its scientific name is hexagon socket bolt assembly.
This kind of bolt is a common furniture fastening hardware connector. Moreover, it is an important fastener, which is usually used to fix the legs of tables. The rigorous hardware connection is usually shown in the figure below. When used with the cross bar nut, the spring washer is used.
Because once the bolts and nuts are fastened, there is a gap between them. After a long time of use, the furniture will inevitably shake, which is likely to cause the screws to loosen.
In addition! Wood will be cold stretched and hot shrunk. The main function of spring washer is to give buffer space. In terms of the design idea, the spring washer (also known as the spring washer) has pre tension, and after being compressed, it will rebound.
In practical use, due to the characteristics of the thread, it is easy for the nut to rotate along the direction of the thread after tightening, resulting in loosening of the nut.
In order to solve this problem in the early stage, spring washers appeared. Due to the pre tension of the spring washer, after the nut compresses the spring washer, under the effect of the pre tension, the triangular buckle in the nut and one side of the triangular buckle of the bolt will be closely stuck together. Under the effect of friction, the nut will no longer be loose.
The ordinary washer (also known as round hole washer, flat washer or ordinary washer) is a support under the pre tension of the spring washer, which increases the pressing area of the pre tension of the spring washer.
