Latest Patents
James Nelson Pratt holds a patent for a Replaceable Roller Bearing. This invention presents a turret/vessel bearing arrangement and a method for replacing bearings in situ without the need to remove other bearings. The design allows for the bearings to be separated, enhancing the maintenance process. A removable axial spacer secures the vessel and the turret in engagement with the upper and lower thrust bearings. By removing the spacer, increased separation between the vessel and turret flanges is achieved, which sandwich the thrust bearings. The mid radial bearing assembly includes one or more radially arranged bearing pads that permit limited axial displacement of the turret concerning the vessel during thrust bearing replacement while still bearing radial loads and allowing rotation. The addition of a temporary thrust bearing enables the vessel to weathervane about the turret while thrust bearings are replaced in situ.
