An interlaced wave spring is formed from two constituent wave springs of similar thickness, amplitude and frequency. The two constituent wave springs are combined together by interlacing them so that the spring turns of each spring abut each other for substantially the entire length of the interlaced spring. This interlacing effectively increases the thickness of the spring turns of the interlaced spring to thereby provide increased loading and greater fatigue resistance characteristics.

In a crest-to-crest wave spring generally spirally wound around a longitudinal spring axis and having a plurality of spring turns including a plurality of successive waves in which the waves include alternating wave crest and wave trough portions, the improvement comprising: the spring being formed from at least first and second constituent crest-to-crest wave springs interlaced together, the first and second constituent wave springs each including first and second continuous flat wire strips generally spirally wound around respective first and second longitudinal axes of said first and second constituent wave springs, said first and second constituent wave springs each having a plurality of successive waves having alternating wave crest and wave trough portions, said first and second constituent wave springs being interlaced together along their respective spring lengths, whereby said first and second wave spring wave crest and wave trough portions lie adjacent each other and whereby said first and second flat wire strips substantially abut each other along substantially the entire spring lengths of said first and second constituent wave springs without any significant gap occurring between said adjacent first and second constituent wave springs, said first and second wave spring wire strips cooperating together to define spring turns within said wave spring of increased thickness.
