Single conical surface combined disc spring

The invention discloses a single conical surface combined disc spring which comprises a plurality of coaxially stacked disc springs, one surface of each disc spring is an internally concave conical surface, the other surface of each disc spring is a plane, the surfaces having the same shape of the adjacent disc springs are in butt joint, an annular cushion for supporting is arranged in the inner diameter between the planes, an annular groove is arranged in the joint of the conical surfaces of the adjacent disc springs, and a locating ring is connected in the groove in a sleeved manner. One surface of each disc spring of the single conical surface combined disc spring is a plane, and the other surface of each disc spring of the single conical surface combined disc spring is a conical surface, so that higher load bearing strength is achieved, the number of the disc springs required to be installed within certain distance is relatively small, the deflection of the spring is large, the stroke is large, the load is increased, internal and external guide devices are saved, and the cost is lowered.
