Furthermore, the outer ends of the tongues are fixedly connected with the outer ring into a whole, and the tongues are fixed on the inner edge of the outer ring and extend inwards; the middle position of each tongue piece is provided with a notch from the outer ring to the middle part of the tongue piece.

Further, the corrugation shape on the tongue piece is a sine wave corrugation shape consisting of a plurality of sine waves, and the sine wave corrugation shape comprises a plurality of wave crests and wave troughs.

Furthermore, the overall corrugated shape of the tongue piece is a sine wave corrugated shape and spreads from the center to the outer ring.

Further, the corrugated shape on the tongue consists of two sinusoidal periods forming two peaks and one valley.

Furthermore, the tongue piece and the outer ring are both made of annealed spring steel plates with the hardness of less than 180 HV.

Advantageous effects

The utility model provides a pair of dish wave spring compares with traditional prior art, and it has following beneficial effect:

(1) the technical scheme has the advantages that the wave spring occupies small axial space, saves installation space, has a larger rigidity range, and can bear larger pressure and impact force.

(2) This technical scheme connects gradually through a plurality of tongue piece, connects into a whole around connecting into, sets up whole to dish to and all set up a plurality of ripple shapes on every tongue piece, the axial pressure is born through every ripple shape bending deformation to ripple shape overall structure by the center outdiffusion, the setting of a plurality of ripples, makes dish-shaped wave spring possess more crests and bear axial pressure.

(3) Each ripple shape on the tongue piece among this technical scheme is just equivalent to a little spring, and the shape of arranging of tongue piece is equivalent to being provided with a plurality of little springs of evenly arranging in the outer ring, through the even atress of a plurality of little springs for the dish-shaped wave spring has bigger rigidity scope, can bear bigger pressure and impact force, compares in ordinary wave spring, and the rigidity of dish-shaped wave spring can reach more than fivefold of the wave spring of the same external diameter.
