ABSTRACT:
Resilient mount assemblies provide absorption of induced loads while permitting some degree of relative rotation between the elements. It is desirable to have resilient mount assemblies which can withstand heavy operating loads while having high angular rotation. In this arrangement, a resilient mount assembly is provided having a segmented assembly interconnecting a first member having a spherical outer surface with a second member having a transverse bore therein. The segmented assembly includes first and second semi-circular half shells with first, second, third, and fourth semi-circular elastomeric layers disposed on respective first and second sides thereof. The first and second semi-circular half shells and their respective first, second, third, and fourth semi-circular elastomeric layers are disposed in intimate contact with the spherical outer surface of the first member. A preloading mechanism is provided and operative to induce a radial force into the first, second, third, and fourth semi-circular elastomeric layers during the assembly thereof. Once the preloading mechanism has been pressed to its full assembled position, the resilient mount assembly has the ability to withstand high operating loads while still having the ability to have high angular rotation between the elements thereof.
