Abstract
HMC"s approach to Phase I HLRB roller bearing design was to achieve separation of the radial and axial functions of the bearing so as to enable axial bearing movement independent of bearing rotation. HMC"s rationale for this approach was that the delineation of axial and radial loads will ensure that each load bearing member can withstand the static and dynamic force vectors to which it will be exposed during numerous and frequent helo bay door operations. During Phase II work, HMC will conduct more in depth contact stress evaluations of HLRB designs under stresses similar to those in helo bay door operations. These evaluations will include Roller Hertzian calculations that determine the magnitude of subsurface stresses carried by the HLRB bearing materials of fabrication under applied loads that are more representative of helo bay door operations. During Phase II HMC also plans to fabricate and use more sophisticated testing apparatus with which to test more matured HLRB prototype design(s). This equipment will provide more representative and accurate Hertzian calculations than were available during Phase I efforts. Phase II efforts will also involve the design of advanced HLRB models that incorporate alternative bearing components and fabrication materials capable of providing greater yield strength and corrosion resistance.
