Definitions
- the subject of the invention is a de-oiler arrangement, located at the end of the turbine shaft of a turbomachine.
- Such a de-oiler (which can be found in a description of a model in EP 0 780 546 A) is placed at the outlet of an air flow maintained in the machine for transporting the oil which lubricates bearings or d other parts, in order to separate the air from the oil that is dispersed in fog before rejecting the air to the outside, and to return the oil to the inlet of the lubricating device.
- the recovery of the oil avoids pollution from the outside, the drying of the lubrication circuit or even fires by depositing on hot external parts.
- the model considered here of the de-oiler comprises three main parts: a hub for mounting and positioning the de-oiler on a vent shaft, concentric with the turbine shaft and protruding from the rear of the the machine, and extending in front of the end of the turbine shaft; a cover defining a housing with the hub; and a filter, possibly a honeycomb network, contained in the housing, retained by the cover and responsible for the separation of air and oil, which is deposited on the walls of the honeycomb when the vent shaft rotates the de-oiler.
- the cover is bolted to the hub to retain it in place, but the use of bolts weighs down the assembly and complicates the assembly.
- Another solution is to weld the cover to the hub. This solution has the disadvantage that said lid is no longer removable.
- the cover and a closing flange of the housing are provided with circular hubs for successively threading them on the vent shaft.
- the cover is retained axially both by pins passing through its hub and the vent shaft, and by abutment faces belonging to the turbine shaft and the closure flange.
- the closure flange seems retained axially by a nut screwed onto the vent shaft. The arrangement is complicated.
- the subject of the invention is an improved de-oiler arrangement, also lightened compared to the bolted de-oiler, more easily removable than the welded de-oiler, and also offers a very good cohesion between the hub and the lid, while allowing simple mounting on the vent shaft.
- the invention relates to a de-oiler arrangement
- a de-oiler arrangement comprising a turbine shaft, a vent shaft surrounded by the turbine shaft, the de-oiler comprising a sleeve hub mounted on the drive shaft. in the open air and hub flange extending out of the sleeve, and a cylindrical lid and spacer flange cover surrounding the sleeve, the hub flange comprising a flange in which the spacer is engaged by one end, characterized in that the cover flange is engaged on the sleeve, the sleeve is retained in a direction of elongation of the shafts by a member of the vent shaft and an element of the turbine shaft, and the cover flange is retained in the direction of elongation of the shafts between a first abutment face belonging to the sleeve and a second abutment face belonging to either the sleeve or the turbine shaft.
- the cover is retained by the abutment faces, excluding any means of attachment. Significant relief is obtained as well.
- the lid is no longer mounted on the vent shaft after the hub, but on the hub: the vent shaft carries the means for abutting only one of the two elements of the de-oiler and is therefore simplified; by being retained on the hub by its two opposite ends, the lid is assembled with a much better cohesion hub; finally, it is easy to arrange the sleeve of the hub to make it carry one of the abutment faces of the flange cover, or both.
- the first abutment face may be constituted by a cleat of the sleeve; the second abutment face, by one end of the turbine shaft, or, perhaps better, by a ring engaged on the sleeve.
- Another aspect of the invention is the de-oiler itself having the above characteristics, regardless of its mounting position.
- FIG. 1 and 2 show a first embodiment of the invention, in perspective and in longitudinal section respectively;
- FIGS. 3 and 4 are similar to FIGS. 1 and 2 for a second embodiment of the invention.
- the arrangement comprises a de-oiler 4, a shaft 1 venting, a turbine shaft 2 concentric with the previous and surrounding it; the shafts 1 and 2 extend in a longitudinal direction of the machine to which they belong, the vent shaft 1 protruding beyond one end 3 of the turbine shaft 2 towards the back of the machine.
- the de-oiler 4 comprises a hub 5 consisting essentially of a cylindrical sleeve 16, mounted on the vent shaft 1 and abutting a shoulder 15 of the turbine shaft 2, and a hub flange 6, flat, perpendicular to the shafts 1 and 2 and extending outside the sleeve 16 being integral with it.
- the de-oiler 4 further comprises a cover 8, defining with the hub 5 a housing 9 in which a filter 10 is contained.
- the housing 9 is delimited by the sleeve 16, the hub flange 6, a lid flange 11 parallel to the previous one, and a spacer 12 belonging to the lid 8, cylindrical and surrounding the sleeve 16 in a concentric state to itself and to the shaft
- the spacer 12 is integral with the cover flange 11.
- One end of the spacer 12 opposite the cover flange 11 extends under a flange 13 of the hub flange 6.
- the cover 8 is held axially by a double stop of the cover flange 11 against a cleat 14 standing on the hub 5 by its inner face to the housing 9 and towards the rear of the machine, and against the end 3 of the turbine shaft 2 by its outer face and forward.
- a longitudinal clearance is however provided, especially in order not to compress the spacer 12 thin, perforated and subjected to significant centrifugal forces in use.
- This double-stop arrangement makes it possible to retain the cover 8 without any means of attachment other than nesting parts. It is obtained by placing the hub flange 6 at the rear of the hub 16, contrary to the usual designs including that of the previous patent, where this flange is adjacent to the end 3.
- the cohesion of the assembly is improved by the radial nesting of the cover 8 in the hub 5, the cover flange 11 being engaged around the sleeve 16 and the flange 13 surrounding the spacer 12 to the other opposite end of the lid 8.
- the lid 8 is completely separated from the vent shaft 1.
- the vent shaft 1, the hub 5 and 1 'spacer 12 are perforated to allow a centripetal flow of air through the de-oiler 4.
- the filter 10 is a network of honeycomb whose channels are oriented radially; its function is to collect the oil in suspension in the flow by depositing on the walls of the honeycomb and to push it outwards thanks to the centrifugal forces caused by the rotation of the de-oiler 4, and thus let pass only a perfectly dry air, having completed its centripetal movement, in the venting shaft 1.
- Other details of the environment of the de-oiler which are however not part of the invention, can be found in EP 0 780 546 A.
- Other fillings, such as beads, have been employed and may still be suitable.
- the spacer 12 is not only thin but perforated to allow the flow of the oil by centrifugation and therefore consists of a group of straps 19 along its circumference between the flange of the hub 6 or 6 'and the flange of lid 11 or 11 '. These straps 19 are subject to significant bending due to centrifugal forces, which is likely to create stress concentrations at where they are connected to the lid flange 11 or 11 '.
- the cover flange 11 or 11 ' with an edge 20 at its outer circumference, where the cover flange 11 or 11' is connected to the spacer 12, which protrudes the opposite side to the spacer 12, that is to say toward the front of the machine in the embodiment of Figures 1 and 2 and rearward in the embodiment of Figures 3 and 4, while extending the spacer 12.
- the overhang of the rim 20 combined with the centrifugal forces it undergoes bending the end of the lid flange 11 or 11 'which contributes to balancing that which it undergoes from the spacer 12 and thus reduces the stress concentrations at its outer edge.
