摘要： Aspects of the invention relate to a system for reducing relative movement between the outer shroud of a compressor diaphragm and the compressor cylinder of a turbine engine, thereby minimizing the wearing of these parts. Embodiments of the invention include a system for applying an axial preload on the outer shroud of a compressor diaphragm, preferably in the same direction as the gas load in the compressor. The system can be installed at or near the horizontal joint such that the axial preload can be applied substantially at the horizontal joint, which is the location of the largest relative movement. In one embodiment, the axial preload system can include a two-piece wedge block and pin. As the pin is driven between the two wedge blocks, the force applied to the pin can be converted to an axial load by the spreading apart of the two wedge block sections.

摘要： A seal for coaxial inner and outer spools rotatable about an axis is provided which includes a flange having a catch surface. The flange is attached to the outer spool, and is disposed between the inner and outer spools such that the catch surface is in close proximity to the inner spool. The catch surface, which includes a seal end and a discharge end, is canted from the axis between the seal end and the discharge end. Liquid disposed between the inner spool and the catch surface is forced against the catch surface by centrifugal force when the spools rotate at a sufficient speed. The liquid is subsequently driven axially along the canted catch surface in the from the seal end to the discharge end, toward the bearing compartment.
