Abstract:
A preloaded device comprisinga female component having a right-circular cylindrical internal surface and a cylindrical axis;a first helical recess in the internal surface of the female component;a male component having a right-circular cylindrical external surface sized to be slidably received within the right-circular cylindrical internal surface of the female component;a second helical recess in the external surface of the male component, the second helical recess having a helical pitch which is the same as that of the first helical recess, so that the second helical recess is in facing relationship along its length to the first helical recess when the male component is assembled to the female component; anda spring component received within the first helical recess and the facing second helical recess when the male component is assembled to the female component, wherein the spring component has an annular, planar, circular shape with a radial slit therein prior to positioning within the first helical recess and the second helical recess.
