A shaft coupling device is provided that includes a first portion, a second portion, a plunger, and a spring. The first portion includes a female mating section and a shaft mounting section. The female mating section includes a first cavity surrounded at least in part by a wall. An aperture extends through the wall. The second portion includes a male mating section and a shaft mounting section. The male mounting section is sized so as to be receivable within the cavity of the female mating section. The male mounting section includes a second cavity surrounded at least in part by a wall, and an aperture extending through that wall. The plunger has a body with a width and a length, and the length is greater than the width. A flange is attached to one end of the body. The plunger is disposed within the second cavity of the male mating section and the body of the plunger extends through the aperture within the wall of the male mating section. The spring is disposed within the cavity of the male mating section, and acts between the wall of the male mating section and the plunger. In a coupled state, the male mating section is received within the cavity of the female mating section and the body of the plunger extends through the apertures within the male and female mating sections and is biased in place by the spring.

The self-aligning pitch bearing rotor assembly of claim 1 wherein said pitch hinge bearing is secured to said pitch shaft member. 3. The self-aligning pitch bearing rotor assembly of claim 2 wherein said pitch hinge bearing is secured to said pitch shaft member with bolt members. 4. The self-aligning pitch bearing rotor assembly of claim 1 wherein said inner and outer race members are each comprised of a metallic material and said middle race member is comprised of an elastomeric material. 5. The self-aligning pitch bearing rotor assembly of claim 1 wherein said inner and outer race members are each comprised of a monolithic metallic structure. 6. The self-aligning pitch bearing rotor assembly of claim 1 wherein said pitch hinge bearing is self-lubricating. 7. The self-aligning pitch rotor assembly of claim 1 further comprising a second pitch hinge bearing, said first pitch hinge bearing positioned on the end portion of the pitch shaft member and said second pitch hinge bearing positioned on the central portion of the pitch shaft member. 8. The self-aligning pitch bearing rotor assembly of claim 7 further comprising a second hinge sleeve member, said second hinge sleeve member comprising an inner race member, an outer race member and a middle race member, said middle race member being comprised of a material which is relatively softer than the material comprising said inner and outer race members, said second hinge sleeve member positioned between said second pitch hinge bearing and said pitch housing member. 9. The self-aligning pitch bearing rotor assembly of claim 7 wherein said pitch hinge bearings are self-lubricating. 10. A method for minimizing contact stress peaking in a rotor dynamic hinge bearing comprising: positioning a first pitch hinge bearing on a pitch shaft member, said pitch shaft member having an end portion and a central portion; positioning a first hinge sleeve member on said first pitch hinge bearing, said first pitch sleeve member comprised of an inner race member, an outer race member and a middle race member, said middle race member being comprised of a material which is relatively softer than the material comprising said inner and outer race members; and positioning said pitch shaft member inside a pitch housing member, said pitch housing member having a cavity wherein said middle race member accommodates for misalignment of said pitch shaft member and said pitch housing member. 11. The method of claim 10 wherein said first pitch hinge bearing is secured to said pitch shaft member. 12. The method of claim 10 wherein said first pitch hinge bearing is self-lubricating. 13. The method of claim 10 wherein a second pitch hinge bearing is secured to said pitch shaft member, said first pitch hinge bearing is secured to said end portion of the pitch shaft member, and said second pitch bearing is secured to said central portion of said pitch shaft member. 14. The method of claim 13 further comprising a second hinge sleeve member, said second hinge sleeve member comprising an inner race member, an outer race member and a middle race member, said middle race member being comprised of a material which is relatively softer than the material comprising said inner and outer race members, said second hinge sleeve member positioned between said second pitch bearing and said pitch housing member. 15. The method of claim 14 wherein said pitch hinge bearings are self-lubricating.
