Problems solved by technology

[0004] Although the anti-loosening effect of the straight-toothed double-stacked self-locking washer is obvious compared with other anti-loosening washers, its adaptable surface is narrower, and it generally performs well on the surface of aluminum alloy, but the anti-loosening effect on the surface of other materials is unstable, such as 45 #The anti-loosening effect of the steel surface is still not ideal, and the end face of the small tooth is easy to slip between the contact surface of the workpiece

Embodiment Construction

[0021] Such as figure 1 As shown, the double-stacked self-locking washer 100 of an embodiment of the present invention generally includes two sub-washers 10 that engage with each other. One side of the two sub-washers 10 is respectively provided with wedge-shaped large teeth with the center of the circle as the midpoint, and on the other side Radial arc-shaped teeth 12 with the center of the circle as the midpoint are respectively provided. Each arc-shaped tooth 12 is an arc transition from the inner ring edge 14 to the outer ring edge 13 of the sub-washer 10. When in use, the two sub-washers 10 pass through the wedge-shaped large teeth. The end surfaces mesh with each other, and the meshed two sub-washers 10 are bonded together by glue coated on the large tooth surface.

[0022] In this embodiment, the small tooth end surface 11 of the sub-washer 10 in contact with the workpiece surface is optimized from the existing radial straight tooth structure to an arc tooth shape, whic...

Abstract

A double-stacked self-locking washer, comprising two sub-washers meshed with each other. Wedge-shaped large teeth having the center of the circle as the midpoint are provided on one side of the sub-washers and radial arced teeth having the center of the circle as the midpoint are provided on the other side. Each arced tooth is an arced transition from the inner annular edge to the outer annular edge of the sub-washers. The two sub-washers are meshed with each other via the wedge-shaped large teeth sides. The double-stacked self-locking washer has the advantages of great meshing stability, a wide range of applications, and strong locking capability.

Description

technical field [0001] The invention relates to a fastening component, in particular to a double-stacked self-locking washer capable of improving the bite force when fastening various materials. Background technique [0002] The double-stacked self-locking washers in the prior art are generally composed of two intermeshing sub-washers. The side of the two sub-washers in contact with each other is a wedge-shaped large-tooth end face with a small distribution density, and the outward side of the two sub-washers is respectively distributed. The end face of the small tooth with high density, the end face of the small tooth is generally a radial straight tooth structure. [0003] During installation, threaded fasteners are generally composed of bolts, nuts and double-stacked self-locking washers to connect the workpieces together. After the bolt head passes through the double-stacked self-locking washers, it is put into the parts to be connected with through holes or threaded hol...
