Technical Field
The invention relates to the field of spring cushions, in particular to a butterfly spring cushion.
Background
The disk spring is in a conical disk shape, can be used singly or in series or in parallel, bears static or dynamic loads acting along the axial direction at the upper inner edge and the lower outer edge, is compressed to generate deformation until being flattened, and is used as a live load in a stored energy mode. When necessary, automatically converts into additional compression load required by sealing, so as to reduce the continuous requirement of tightening in the use of gaskets and packing. The disc spring is a special spring which is conical in the axial direction and bears load, certain potential energy is stored after the disc spring bears load deformation, and when the bolt is loosened, the disc spring releases partial potential energy to keep the pressure between the flange connections to meet the sealing requirement. The stress distribution of the disc spring is uniformly decreased from inside to outside, and the effect of low stroke and high compensation force can be realized.
However, in practical use of the traditional disc spring piece, due to the fact that the diameters of the screw rod and the hollow hole in the middle of the disc spring piece are different, the disc spring piece can deviate when the screw rod is screwed down, and particularly when a plurality of disc spring pieces are used in parallel or in series, the connection strength can be affected.
