How do spring washers prevent the nut (or bolt) from automatically loosening back?

The spring washer device is used under the nut to prevent the nut from loosening, and it is described in the national standard. Hexagonal slotted nuts are specially designed for use with bolts with holes at the end of the screw, so that the cotter pin can be inserted into the hole of the screw from the groove of the nut to prevent the nut from automatically loosening. It is mainly used for vibration loads or alternating loads. . The function of the spring washer is mainly to prevent the nut (or bolt) from automatically loosening during the mechanical design and manufacture. The methods are: 1. Pad spring washer; (easy to do) 2. Use hexagonal slotted nut + cotter pin; (increase the processing process compared with the same period of last year) 3. Pad the stop washer; (increase the processing process compared with the same period) 4. The hex head opening of the hex bolt is inserted into the steel wire. (Increased processing steps year-on-year)
