ABSTRACT:
A laminated bearing comprises a plurality of alternating and bonded layers of elastomeric material and nonextensible material. The layers alternate along a common axis extending lengthwise of the bearing so that the bearing can support substantial compressive loads applied generally normal to the layers. Each layer is contoured to have, in section taken radially of the common axis, a portion projecting longitudinally toward one end of the bearing. Under large compressive loads, the contour of the layers may contribute to excessive strains in the elastomeric layers adjacent the end of the bearing toward which the layers project. To accommodate the compressive stresses without excessive strains, the layers of elastomeric material in a central lengthwise portion of the bearing have smaller compression moduli than the layers of elastomeric material adjacent the one end of the bearing.
