ABSTRACT:
A rotor (10) for a centrifugal separator (12) for circulated engine lubricant formed by end walls (44, 46) and radially outer and inner side walls (42, 52) that define a separation and containment region (82). Wall (52) is defined by a tubular tension member (50) that surrounds a rotation axis (30) and extends between and through the end walls to keep them in position. Mounted within first and second ends (72, 74) of the tubular tension member are respective first and second end closure plugs (86, 88). Plug (88) has a passage (90) to admit liquid into the tubular member, but otherwise each plug is seated to inhibit passage of liquid from the member end. Each plug comprises a body seated by interference fit and an integral axially extending component (86′, 88′) that forms a mounting pin for mounting the rotor within bearing parts (24, 28) of the housing. Closure plugs may be assembled from separate plug body and fixed or rotatable mounting pin components and may extend along the tubular member and be coupled to each other, or be formed integrally as a unitary body, or share a common mounting pin that extends between discrete plug bodies.
