Patent ID: 8632062

Claim:
A rotary wing aircraft bearing to provide a constrained relative motion between a first rotary wing aircraft member and a second rotary wing aircraft member, an elastomeric mold bonded laminated subassembly, said elastomeric mold bonded laminated subassembly including a plurality of mold bonded alternating layers of interior nonelastomeric shim members and interior elastomeric shim members, said interior elastomeric shim members including a first laminate end elastomeric shim and a distal second laminate end elastomeric shim, said first laminate end elastomeric shim having a first side mold bonded to a first end interior nonelastomeric shim member and a second side mold bonded to a first metal first laminate end structural bond shim, said distal second laminate end elastomeric shim having a first side mold bonded to a distal second end interior nonelastomeric shim member and a second side mold bonded to a second metal distal laminate end structural bond shim, said elastomeric mold bonded laminated subassembly having an elastomeric subassembly tensile strength ESTS between said first metal first laminate end structural bond shim and said distal second laminate end elastomeric shim, said rotary wing aircraft bearing including a first end bearing connector first metal member for connecting to said first rotary wing aircraft member, a first end structural chemical adhesive post-elastomeric mold bond between said first end bearing connector first metal member and said first metal first laminate end structural bond shim, said first end structural chemical adhesive post-elastomeric mold bond having an elongation of at least 11%, and a first end tensile strength FETS with FETS ≧ESTS, said rotary wing aircraft bearing including a second end bearing connector second metal member for connecting to said second rotary wing aircraft member, a second end structural chemical adhesive post-elastomeric mold bond between said second end bearing connector second metal member and said second metal first laminate end structural bond shim, said second end structural chemical adhesive post-elastomeric mold bond having an elongation of at least 11%, and a second end tensile strength SETS with SETS ≧ESTS.
