Abstract:
1. A method of assembling a sealing assembly for use in a turbomachine, said method comprising: providing a rotatable element that rotates about an axis of rotation and includes an end portion including a first groove and a second groove formed therein, each of the first groove and the second groove partially extending circumferentially about a portion of an outer surface of the end portion of the rotatable element such that each of the first groove and the second groove is arcuate and is substantially perpendicular to the axis of rotation, the first groove being separated from the second groove by a portion of the outer surface of the rotatable element; providing a stationary portion that includes an upper section and a lower section; inserting at least a portion of the end portion of the rotatable element into the lower section; and coupling the upper section to the lower section, thereby defining a rotor shaft cavity, wherein the end portion of the rotatable element at least partially extends through the rotor shaft cavity, thereby defining a clearance between the end portion of the rotatable element and the stationary portion.
