Abstract

The invention belongs to the technical field of belleville springs, and discloses a metal belt type belleville spring with the adjustable elastic force. The belleville spring comprises a pressing plate assembly and elastic sheet assemblies, wherein the pressing plate assembly comprises an upper pressing plate and a lower pressing plate, at least one elastic sheet assembly is arranged and is arranged between the upper pressing plate and the lower pressing plate in a coaxial arrangement mode, the belleville spring further comprises at least one elastic force adjusting assembly, the elastic forceadjusting assemblies comprise limiting pieces and gasket pieces, the limiting pieces are arranged in the elastic sheet assemblies, and the gasket pieces are arranged between two adjacent elastic sheet assemblies. According to the metal belt type belleville spring with the adjustable elastic force, the belleville spring is formed on the basis of the plurality of elastic sheet assemblies, one elastic force adjusting assembly is arranged between every two adjacent elastic sheet assemblies, whether one single elastic sheet assembly can be stretched or not is defined based on the elastic force adjusting assemblies corresponding to the single elastic sheet assembly, then the number and the stretching length of the elastic sheet assemblies actually applied in the overall belleville spring are changed, and then the elastic force magnitude is changed so as to meet different use requirements.

Description

technical field [0001] The invention belongs to the technical field of disc springs, and in particular relates to a metal band-type disc spring with adjustable elastic force. Background technique [0002] Disc spring, also known as Belleville spring washer, is a washer spring with a truncated conical section formed from sheet metal or forging blank. During use, in order to increase the elasticity, disc springs are generally stacked to form a combination. [0003] In the specific application, the elastic force of the spring is: F=kx, where k is the stiffness coefficient, and x is the elongated length of the spring. Generally speaking, if the length of the spring is fixed, the elastic force formed by it is fixed. When the elasticity of the spring needs to be changed, the spring needs to be replaced. [0004] In view of this, in order to realize the multi-demand application of the spring, the present invention proposes a disc spring capable of adjusting the elastic force. C...
