Abstract
There is provided an apparatus for securing a rotor to a drive cone in a centrifuge. The apparatus includes (a) a nut, movable in an axial direction in the drive cone, (b) a screw for passing through a region of the rotor and for engagement with the nut, and (c) a spring located between a surface of the nut and a surface of the drive cone. The screw, when tightened into the nut, moves the nut in the axial direction to compresses the spring between the surface of the nut and the surface of the drive cone.
Claims5
An apparatus for securing a rotor to a drive cone in a centrifuge, said apparatus comprising:
- a nut, movable in an axial direction in said drive cone;
- a screw for passing through a region of said rotor and for engagement with said nut;
- and
- a spring located between a surface of said nut and a surface of said drive cone,
- wherein said screw, when tightened into said nut, moves said nut in said axial direction to compress said spring between said surface of said nut and said surface of said drive cone.
An apparatus for securing a rotor to a drive cone in a centrifuge, said apparatus comprising:
- a nut, movable in an axial direction in said drive cone;
- a screw for passing through a region of said rotor and for engagement with said nut;
- a spring located between a surface of said nut and a surface of said drive cone;
- and
- a retaining ring for holding said nut and said spring in said drive cone,
- wherein said retaining ring is located adjacent to a perimeter region of said nut, within an annular groove of said drive cone,
- wherein said screw, when tightened into said nut, moves said nut in said axial direction to compress said spring between said surface of said nut and said surface of said drive cone, and
- wherein said nut has a protrusion that fits into a slot in said drive cone to limit rotation of said nut with respect to said drive cone.
