Embodiment Construction

[0030] The following description of the exemplary embodiments refers to the accompanying drawings.

[0031] The following description does not limit the invention. Rather, the scope of the invention is defined by the appended claims.

[0032] Reference throughout the specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosed subject matter. Thus, appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout the specification are not necessarily referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0033] Referring specifically to Figure 6, a turbomachine, particularly a gas turbine, is shown.

[0034] The turbine comprises an axial air compressor 50 driven by a turbine ...

Abstract

A containment sleeve (23) of a turbomachinery bearing (22), the sleeve (23) comprising a body defining a surface (23A) configured to support a turbomachinery bearing (22), and at least a first (25A) and a second hole (25B) opening on said surface (23A), said first (25A) and a second hole (25B) being provided to collect lubricating / cooling fluid draining from said bearing, the body further defininga first (27A) and a second groove (27B) disposed at opposite sides of said surface (23A), a first channel (30A) fluidly connecting said first hole (25A) with said first groove (27A), and a second channel (30B) fluidly connecting said second hole (25B) with said second groove (27B), the first and the second channel being opened on that surface (23A) and being separated by a wall (31) having at least a bearing support surface (31A) that is part of said surface (23A).

Description

technical field [0001] Embodiments of the herein disclosed subject matter correspond to a closure sleeve for a turbomachine bearing and a turbomachine equipped with the same. Background technique [0002] A turbine, especially a gas turbine, is generally defined as a rotating heat engine that converts heat successfully using gases supplied directly by combustion and supplies mechanical power to a rotating shaft. It generally consists of a compressor or turbo compressor (usually of the axial type) within which air from the outside is carried under pressure. Additionally, a plurality of injectors supply fuel that mixes with air to form an air-fuel injection mixture. [0003] The axial compressor is driven by a dedicated turbine that supplies mechanical power to the utiliser, converting the enthalpy of the fuel within the combustion chamber. [0004] Specialized turbines, turbo compressors, combustors (or boilers), mechanical power output shafts, control systems and start-up ...
