Patent attributes
An interlocking disc spring assembly includes a plurality of alternating interlocking first conically-shaped disc springs and second conically-shaped disc springs. The first disc spring includes a first radial inner portion and a first radial outer portion. The first radial inner portion defines a first opening therethrough and includes an upwardly-extending portion spaced from the first opening. The first radial outer portion includes a downwardly-depending portion. The second disc spring has a second radial inner portion and a second radial outer portion. The second radial inner portion defines a second opening therethrough and includes a downwardly-depending portion. The second radial outer portion of the second disc spring is receivable within the downwardly-depending portion of the first radial outer portion of the first disc spring when the first disc spring is stacked on the second disc spring. The downwardly-depending portion of the second radial inner portion of the second disc spring is receivable within the upwardly-extending portion of the first radial inner portion of the first disc spring when the second disc spring is stacked on the first disc spring. In another embodiment, an adjustable spacer may connect the inner portions of adjacent interlocking disc springs.
