Abstract
A dynamic bushing and/or gripper mechanism comprises an apparatus for retaining a tubular member in a position during processing so that the tube does not move transverse to the longitudinal axis of the bushing, but wherein the tube may be rotated within the confines of the bushing and/or in the case of the gripper mechanism the tube may be moved longitudinally within the confines of the gripper.
Claims15
A dynamic bushing assembly for preventing a tubular member from moving transverse to a longitudinal axis defined thereby but permitting the tube to be rotated about the longitudinal axis, the assembly comprising:
- a tube retention area, the tube retention area being defined at least partially defined by a crown member, the crown member defining an apex, the apex having at least one top guide member extending therefrom into the tube retention area, the tube retention area being further defined by a surface of a piston, the piston being moveable toward and away from the apex, the surface of the piston having at least two bottom guide members extending therefrom into the tube retention area, wherein at least one of the guide members comprises a roller ball.
