Abstract
A snubber inner member has a doubly convex outer surface portion having a central longitudinal axis. A shim/spacer stack secured to the outer surface portion couples the snubber inner member to the second member. A retainer having one or more engagement surfaces cooperates with one or more engagement surfaces of the snubber inner member to constrain lateral movement of the snubber inner member relative to the retainer while permitting longitudinal movement of the snubber inner member away from the retainer. An elastomer secures the retainer to the first member.

A snubber system for permitting relative rotation of a first member and a second member comprising:
- a snubber inner member having a doubly convex outer surface portion having a central longitudinal axis;
- a shim/spacer stack secured to the outer surface portion and coupling the snubber inner member to the second member;
- a retainer having one or more engagement surfaces cooperating with one or more engagement surfaces of the snubber inner member to constrain lateral movement of the snubber inner member relative to the retainer while permitting longitudinal movement of the snubber inner member away from the retainer and the first member;
- and
- an elastomer securing the retainer to the first member.
A snubber system for permitting relative rotation of a first member and a second member comprising:
- a snubber inner member having a doubly convex outer surface portion having a central longitudinal axis;
- a shim/spacer stack secured to the outer surface portion and coupling the snubber inner member to the second member;
- and
- means for constraining lateral movement of the snubber inner member relative to the first member while permitting longitudinal movement of the snubber inner member away from the first member.
A snubber system for permitting rotation of a rotor blade flexbeam relative to a housing member, comprising:
- a first snubber inner member having a doubly convex first outer surface portion;
- a first shim/spacer stack secured to the first outer surface portion and coupling the first snubber inner member to housing member;
- a first retainer having one or more first engagement surfaces cooperating with one or more first engagement surfaces of the first snubber inner member to constrain lateral movement of the first snubber inner member relative to the retainer while permitting movement of the snubber inner member away from the retainer and the rotor blade flexbeam;
- a second snubber inner member having a doubly convex second outer surface portion;
- a second shim/spacer stack secured to the second outer surface portion and coupling the second snubber inner member to the housing member opposite the first snubber member;
- and
- a second retainer having a second engagement surface cooperating with a second engagement surface of the second snubber inner member to constrain lateral movement of the second snubber inner member relative to the second retainer while permitting movement of the second snubber inner member away from the second retainer and the rotor blade flexbeam.
