Problems solved by technology

The disadvantage is that the anti-loosening slope is very short, and the consistency between the major diameter and the major diameter of the bolt is very high.
Several types of anti-loosening nuts introduced in the national standard manual also have th

Embodiment Construction

[0006] National standard nuts and flange nuts have good connection performance, but their anti-seismic and anti-loosening capabilities are limited. With the reloading and high-speed operation of various mechanical equipment, the problem of nut loosening becomes more and more prominent. Increase the diameter of the flange surface of the flange nut, add a rectangular, semi-circular, and trapezoidal skirt to the outermost edge of the flange nut, so that the bottom surface of the flange and the workpiece are completely suspended, and make the flange rectangular, semi-circular, and The trapezoidal circular skirt first contacts the workpiece, and the outer edge of the flange is deformed greatly when the rectangle, semi-circular arc, and trapezoidal circular skirt are partially stressed. At this time, the stress point of the rectangular, semi-circular, and trapezoidal skirts is at the outermost edge of the flange, and the formed spiral arm is the largest, and the stored elastic potent...

Abstract

The invention discloses a rectangular, a semicircular and a trapezoidal round skirt check bolt and a nut for flange, and belongs to the technical field of lock fasteners. Flange face of a lock bolt and nut should be large enough, an annular platform is arranged on the outermost ring of the flange face, flange rectangles, semicircular arcs and trapezoidal round skirts are arranged on the periphery of the edge of the annular platform and enable the flange face to be suspended, and the flange rectangles, the semicircular arcs and the trapezoidal round skirts make contact with a workpiece firstly during installation, are stressed firstly and transmit force to the flange face; as the outermost edge of the flange is stressed, the deformation of the flange is large. By means of the design, the elastic coefficient is small, the elastic variation is large, and the elastic potential energy stored by the flange is large, and the anti-vibration and anti-loosening capabilities are high.

Description

technical field [0001] The invention relates to a flange rectangular, semicircular arc, trapezoidal circular skirt locknut and bolt. The bottom surface of the flange is suspended by using the rectangular, semi-circular, and trapezoidal skirts of the flange, and the rectangular, semi-circular, and trapezoidal skirts on the flange edge are forced to cause local deformation of the flange, thereby storing elastic potential energy to prevent nuts and bolts from A loosening device belongs to the technical field of anti-loosening fasteners. Background technique [0002] Preventing thread loosening has always been the goal pursued by engineers and technicians. Since the appearance of thread, the problem of loosening has not been solved well. Locknuts have appeared in recent decades, and there are many forms. Everyone has different research directions and different research results. Among them, the representative work should be the tooth-changing locknut launched by the Spielock To...
