An oil slinger is held in place on a shaft by an O-ring which serves as a detent when the shaft is at rest and as a static seal when the shaft is rotating. Because the slinger is held only by a detent action in the rest position, the slinger can be moved aside during assembly and disassembly of the companion bearing and seal structure and thereby provide greater access.

Oil slinger and method of mounting

A turbomachine lubricating oil system comprising a casing having a relatively large diameter member rotatably mounted therein with a chamber defined thereby. A support for said casing includes a generally hollow structural member defining a quiescent plenum. Lubricating oil flows from said casing chamber to the quiescent plenum. Oil flows from the quiescent plenum to a lubricating oil reservoir.

Turbomachine lubricating oil system

A member interposed between the inner and outer casings of a rotary machine which is arranged to hold the casings in concentric alignment with the machine shaft as the two casings undergo transient thermal and pressure growth.

Compensating ring for a rotary machine

An adjustable blade assembly for use in a rotary machine, such as a turbine or a compressor, wherein the airfoil is separable from the assembly at the blade platform. The airfoil is provided with a root which is seated within a complementary kerf formed within the platform. Each of the two sections is fabricated independently using standard machine tools, thereby eliminating the need of hand-forming, complex blade contours. In assembly, the airfoil is loosely supported within the platform whereby the stresses generated at resonant frequencies are highly damped.
