Patent ID: 7578466

Claim:
An aircraft mechanism for reducing heat generation in a pivot joint comprising: a first member; a second member; a pivot pin connecting said first and second members to allow said first and second members to oscillate relative to one another about said pivot pin; and a plurality of linked members, wherein one of said linked members is rotate-ably attached to said first member, another of said linked members is rotate-ably attached to said second member, another of said linked members is rigidly connected to said pin, and each of the linked members are rotate-ably linked to one another; wherein said rigidly connected linked member is adapted to rotate a same amount as said pin when said first and second members oscillate relative to one another about said pivot pin causing each of the linked members to rotate relative to one another and to rotate relative to the first and second oscillating members; wherein said mechanism is adapted so that when said first and second members oscillate about said pin, said pin is simultaneously rotated relative to both of said first and second members as a result of the linked members thereby reducing heat generation in the pivot joint; wherein said mechanism is adapted so that when said second member rotates about said pin, said pin rotates in an amount substantially equal to half of the rotation of said second member wherein said plurality of linked members provide reduced rotational velocities of said pin relative to said first and second members thereby reducing heat generation in the pivot joint.
