It is mainly applied to machinery parts of valves or steel plants and it is made with superalloy with a good working performance under high temperature environment.
In a large range, disc springs are replacing cylindrical helical springs. Commonly used in heavy machinery (such as press) and artillery, aircraft and other weapons, as a strong buffering and damping spring, compression spring for automobile and tractor clutch and safety valve, as well as a mobile device storage element.
Disadvantages: load deviation is difficult to guarantee.
According to the different shape of the cross section of the plate spring can be divided into three categories: including the general dish spring (whose cross section shape is rectangular), with a radial groove dish spring, trapezoidal cross-section dish spring. Belleville spring is divided into a supporting surface and no support surface two; disc spring with radial grooves in Belleville spring, a plurality of uniformly distributed along the radial groove, groove by hole outward circular direction out of, and also by the outer circle inward direction out of the trapezoidal hole; section of the disc spring can be divided into inner and edge thickness is greater than the thickness of the foreign aid thickness is less than the outer circle thickness two.
Because the deformation and load value of the single disc spring can not meet the requirements, the utility model can be used in groups to form a disc spring assembly (column). The typical combination is as follows: a combination of disc springs, a combination of disc springs and other combination disk spring.
