Claims18
A rotor hub assembly, comprising:
- a yoke;
- and
- a high capacity laminated (HCL) bearing, comprising layers of elastomeric material and layers of metal, the HCL bearing being affixed to the yoke to prevent separation of the HCL bearing from the yoke;
- wherein the HCL bearing is not captured by a shape profile of the yoke to which the HCL bearing is affixed;
- wherein the HCL bearing comprises a closed-loop shape disposed about a mast axis of the rotor hub assembly;
- and
- wherein the HCL bearing is affixed to the yoke using a frustoconical shaped profile of the yoke.

A method of constructing a rotor hub assembly, comprising:
- providing a yoke and a mast;
- and
- affixing a high capacity laminated (HCL) bearing to the yoke to prevent separation of the HCL bearing from the yoke without using the yoke to capture the HCL bearing;
- wherein the HCL bearing comprises a closed-loop shape disposed about a mast axis of the rotor hub assembly;
- and
- wherein the HCL bearing is affixed to the yoke using a frustoconical shaped profile of the yoke.
