Method for assembling a flexure bearing

A method of assembling a flexure bearing, comprising:

• providing a first sleeve and a second sleeve, wherein each sleeve includes:
• an inside wall having a cylindrical inner surface;
• a first pillar having three sides, wherein a first end of the first pillar is attached to the inside wall of the sleeve, and a second end of the first pillar projects outwardly from the sleeve parallel to an axis of the sleeve;
• a second pillar having three sides, wherein a first end of the second pillar is attached to the inside wall of the sleeve, and a second end of the second pillar projects outwardly from the sleeve such that the second pillar is parallel to and diametrically opposed to the first pillar;
• a plurality of blind holes, each blind hole near each of the first end and the second end of each pillar,
• wherein each pillar comprises a first side shaped to conform to a sector of the inner surface of the other of the first and second sleeves, a second side having a first flat surface, and a third side having a second flat surface perpendicular to an edge of the first flat surface;
• wherein each pillar has a first blind hole near a first end of the second side, a second blind hole near a first end of the third side, a third blind hole near a second end of the second side and a fourth blind hole near a second end of the third side;
• wherein the first and second pillars of each sleeve are received by the inner surface between the first and second pillars of the other sleeve such that the sleeves are rotatably interconnected about the sleeve axis;
• providing a plurality of compression springs;
• inserting a first spring end of each compression spring into one of the blind holes of a pillar of the first sleeve;
• and
• inserting a second spring end of each compression spring into a corresponding blind hole of an adjacent pillar of the second sleeve when the second sleeve is interconnected to the first sleeve.
