Embodiment Construction

[0024] see Figure 2 to Figure 6 . Embodiments of the present invention are described below through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation modes, and various modifications or changes can be made to the details in this specification based on different viewpoints and applications without departing from the spirit of the present invention.

[0025] Such as figure 2 As shown, the disc springs 10 adopt different combinations, which can change the spring characteristics in a wide range. Usually, the combination methods can be combined, stacked, etc., and a group of single disc springs 10 are stacked and used in the same direction. It is a superimposed combined disc spring; a group of single disc springs are used alternately in different directi...

Abstract

The invention provides a hollow belleville spring which comprises a belleville spring body in a conical ring shape. The hollow structures are arranged on the ring body of the disc spring body at equal intervals, and the total area of the hollow structures is 1 / 3-3 / 4 of the area of the disc spring body. The special application occasion requirements for reducing the rigidity of the disc spring body and achieving the large stroke can be met, the structure is simple, use is convenient, and good use and popularization value is achieved.

Description

technical field [0001] The invention relates to the field of disc springs, in particular to a hollow disc spring. Background technique [0002] Disc springs, also known as Belleville springs, are special springs that are stamped from metal sheets or strips and are tapered in the axial direction and bear loads. They have compact axial dimensions, large radial dimensions, and high rigidity. features. In some specific occasions, the stiffness of ordinary disc springs exceeds the required value. In order to solve this problem, slotted disc springs have appeared on the market. Figure 1A A common slotted disc spring 20 is shown, including a disc spring body 21 and several slots 22 opened on the inner circumference. Although the slotted disc spring 20 can effectively reduce the rigidity of the common disc spring, the slotted disc spring 20 cannot be fitted along the inner circumference because the inner circumference of the slotted disc spring 20 is a disconnected structure, so t...
