Difference between normal leaf spring nuts and high strength leaf spring nuts

The application of plate spring nuts in steel structures is extensive. Plate spring nuts mainly fasten the connection, fixing, and positioning between steel structure components, making them the primary connection fasteners. Plate spring nuts are generally divided into ordinary and high-strength plate spring nuts.

1. Ordinary plate spring nut: the fastening axial force of an ordinary plate spring nut is minimal, and the connecting plate parts are about to produce a slip under the action of external force, and usually, the external force is transmitted through the shear of the plate spring nut rod and the pressure bearing of the connecting plate aperture wall.

According to its processing, production quality, and precision tolerance, ordinary plate spring nut quality can be divided into three quality levels: A, B, and C. The level of processing accuracy is the highest, and the C level is the worst. People, A B-level leaf spring nut is called a refined leaf spring nut, and a C-level is called a crude leaf spring nut. A level applies to small specifications of the leaf spring nut, diameter d_M24, length L <- 150mm and 10d; B level applies to large specifications of the leaf spring nut, diameter d>M24, length L>150mm and ten mountain C level leaf spring nut with not ig curry work of round steel made of rods with rough surfaces, low machining accuracy, inaccurate size. The size is not accurate.

2. High-strength plate spring nut: This is a high-strength plate spring nut connection with reasonable force performance, high connection strength, and good seismic performance.

Fatigue resistance, simple construction, and other characteristics in the construction of steel structures are widely utilized and become the central connectors of steel structures. High-strength leaf spring nuts can be divided into friction-type and pressure-type connections according to the different force characteristics. However, the production of high-strength reed nuts, friction-type, and compression-type only takes different values in the limit state, and there is no difference in manufacturing and construction.

High-strength plate spring nuts in the performance level can be divided into 8.8 level (or 8.8s) and 10.9 level (or 10.95). According to the different construction and construction methods of plate spring nuts, high-strength plate spring nuts can be divided into two categories: sizeable hexagonal head high-strength plate spring nuts and torsion-shear high-strength plate spring nuts. Large hexagonal head high-strength plate spring nut connecting pair contains a plate spring nut, a nut, and two washers type high-strength plate spring nut securing pair includes a plate spring nut, a nut, and a washer.8.8 grade is only used for sizeable hexagonal head high-strength plate spring nuts, 10.9 grade can be used for torsion and shear high-strength spring nuts, and sizeable hexagonal head high-strength plate spring nuts. Torsion-shear high-strength leaf spring nuts are only available in grade 10.9.

For example, high-strength plate spring nuts are commonly used in electrical machinery vibration and shock damping structures, transformers and electromagnets bases, engine blocks and tires, and other structural fastening connections in the mechanical field. High-strength plate spring nuts can be used for cell phones, notebook computers, and other equipment fastening connections for electronic products. They can ensure the reliability and stability of the equipment assembly, reasonable force performance, high connection strength, and good seismic performance.
