Embodiment 1

[0036] see image 3 , 4 pieces of convex arc disc springs are superimposed and combined (stiffness parallel displacement increases). The arc of the spring tends to be gentle. Since the upper and lower contact surfaces of the stacked disc springs are arc surfaces, the stress point of the disc spring will shift from the initial edge of the section to the center point of the section with the change of the compression stroke. On the contrary, when the disc spring pulls When stretching, its stress point will be displaced from the center point of the section to the edge of the section with the change of the stretching stroke; when the compression stroke exceeds 75% of the allowable regulation, the bearing capacity of the disc spring will at least double, which means The overload safety guarantee of the disc spring is greatly improved; and the reliability, safety and service life of the disc spring are improved.

Embodiment 2

[0038] see Figure 4 , two convex arc-shaped disc springs 1 superimposed combination (stiffness series displacement unchanged), when the disc spring is compressed by force, the nature of its deformation force change is that the taper of the disc spring tends to be gentle first, and then the disc spring The arc of the spring tends to be flat. Its characteristic is that the displacement constant bearing capacity is doubled.

Embodiment 3

[0040] see Figure 5 , 4 pieces of convex arc disc spring 1, 2 pieces are superimposed and then combined (stiffness and displacement increase in series), when the disc spring is compressed by force, the nature of its deformation force is first of all that the taper of the disc spring tends to be gentle , followed by the disc spring's arc becoming flatter. Its characteristic is that both displacement and bearing capacity are doubled.

Abstract

The invention relates to a cambered surface disc spring and a manufacturing method thereof. The cross section of the cambered surface disc spring is designed into a tapered arch shape; the arch shape is a heave or a pit on the basis of a tapered shape; the arch rise and the arc length of the arch shape are changed along with the cone height and the diameter of the disc spring; and the arch rise of the arch shape is less than 1/3 of the cone height. The cambered surface disc springs with same arch shapes and different arch shapes can be combined together for use. The cambered surface disc spring adopting the design greatly improves the overload safety guarantee of the disc spring, greatly improves the reliability, safety and service life of the disc spring, and prevents major failure accidents and economic losses.

Description

technical field [0001] The invention belongs to the technical field of disc springs, in particular to a high-performance arc disc spring. Background technique [0002] As an important form in the field of spring technology, disc springs have the characteristics of high rigidity and short strokes. Therefore, they are widely used in the fields of military industry, aerospace, metallurgy, petrochemical, electric power, machinery manufacturing, railway transportation and electrical control. Most of the currently widely used structural forms are conical cross-sections, and there are also a small amount of conical trapezoidal cross-sections. Although the disc springs of these cross-sectional forms are different in use, the force characteristics of the disc springs have not changed. That is to say, the disc springs have changed from Conical to flattened, its deformation force is basically a continuous and complete straight line or curve, and the upper force point and lower support ...
