- TITLE FORMATION OF AN ABRADABLE COATING INSIDE A TURBOMACHINE CASING
- the present invention relates in particular to a tool and a method for forming an abradable coating inside an annular casing of an aircraft turbine engine module.
- the technical background includes in particular the documents CN-U-207 154 055, CN-U-207154 054, FR-A-1 124 416 and JP-B1 -S49 27410.
- a turbine engine comprises at its upstream end (by reference to the flow of gases in the turbine engine) a fan comprising a bladed wheel which is surrounded by a casing, called a retention casing because of its function of retaining the blades in the event of breaking them.
- the blade wheels of a turbomachine are surrounded by a stator which carries an annular coating of abradable material.
- the coating extends around and at a short radial distance from the blades, which in operation can rub against the material and wear it down by friction. This makes it possible to optimize the radial clearances between the blades and the stator which surrounds them and therefore to limit gas leaks at the radially outer tips or ends of the blades.
- the fan blades are surrounded by an abradable layer which covers an internal annular surface of the casing.
- this abradable layer is obtained by spreading a polymerizable resin on the surface.
- This resin is hammered manually to evacuate as many air bubbles as possible and to press the resin onto the crankcase.
- the finishing is done by calendering carried out by passing a rule of form without possible control of the force imposed.
- this calendering tends to impose a detachment force on the resin. It is therefore a manual operation which requires long know-how to acquire, which consequently makes it long to implement and costly.
- the Applicant has already proposed in application W0-A1 -2016/203141 a device for coating a turbomachine casing, which comprises means for depositing resin and means for spreading this resin. These spreading means comprise rollers.
- This device makes it possible to replace manual operations of the prior art with automated and therefore more easily reproducible operations.
- the device further comprises means for unwinding a plastic film intended to be inserted between said rollers and the resin. The plastic film prevents the resin from adhering to the rollers and guarantees a good surface condition (for example smooth and shiny) for the abradable coating.
- This application also describes an installation comprising the device and a transport carriage comprising means for rotating the casing about a horizontal axis.
- the device is intended to be secured to the carriage and the casing is rotated around the horizontal axis so that the resin is deposited and spread in the casing, these steps being automated.
- the Applicant has also already proposed in application FR-A1-3 048 018 a device for applying abradable material to a surface of a turbomachine casing.
- This device comprises several guide means and means for adjusting the position of a spreading roller.
- the Applicant now offers an improvement to these devices. Aims of this improvement are to simplify the formation of the coating and to guarantee the reproducibility of this formation.

- a second part which comprises at least a first transverse arm extending radially outwards and carrying spreading rollers
- a flywheel centered on said axis and configured to be turned manually by an operator with a view to rotating the tool and the rotor inside the casing, so that the spreading rollers are able to spreading a resin for the formation of said coating.
- the abradable coating is obtained by spreading a resin which is prepared beforehand, for example by mixing two or more components.
- This resin is generally in the form of a paste and is deposited on the internal surface of the casing.
- the deposition of the resin can be done manually by an operator.
- the spreading of the resin is carried out by rollers.
- the rollers are carried by the tool which is moved in rotation by means of a flywheel and therefore directly by an operator. This operation is therefore not automated because the human intervention for this operation proves to be important to guarantee a good quality of the spreading.
- the tool is integral with the rotor of the module and therefore rotates with this rotor inside the casing which remains fixed.
- the rollers which are movable around the same axis, and it is the module casing which is fixed. It is simpler and more precise to use the casing as a fixed reference and to rotate the tooling with the rotor of the module, to also guarantee a good quality of the spreading of the resin and of the formation of the coating.
- the invention thus makes it possible to significantly simplify the tooling, to facilitate its use, but also to improve the final quality of the abradable coating.
- the tool according to the invention can be used to spread a resin and form an abradable coating from this resin, inside any which turbomachine casing. It may be, for example, but in a non-limiting way, a casing for retaining the blades of a turbomachine fan.

- the hooks and/or the tabs are located on a circumference centered on said axis, which has a first diameter, and the steering wheel has a second diameter which is greater than the first diameter;
- the first part comprises pegs or support orifices which are parallel to said axis;
- the tool comprises a second transverse arm which is diametrically opposed to the first arm with respect to said axis, and which carries at least one counterweight;
- the tool further comprises a lever for adjusting the radial position of said rollers vis-à-vis said axis;
- the present invention also relates to an assembly comprising a tool as described above, with a transport trolley, this transport trolley comprising a frame, wheels fixed to the frame, a first housing space for said tool, and at least one member support of the tool in said first space so that the axis of the tool is horizontal.
- the assembly according to the invention may comprise one or more of the following characteristics, taken separately from each other, or in combination with each other: - Said support member comprises elements which are complementary to the pins or to the orifices and which are configured to cooperate by male-female engagement with these pins or orifices;

- the method further comprises a step e) of depositing resin on the surface 16 of the casing 10, preferably manually by an operator who previously prepares the mixture of components for the production of this resin. This step can be done in advance.
- the method preferably comprises, between steps d) and e) or after step e), a step of adjusting the radial position of the rollers 80 with respect to the axis A, B, as illustrated in FIG. 13.
- This makes it possible to position the rollers 80 precisely inside the module 40 and with a predetermined radial clearance with respect to the surface 16 of the casing. This clearance is determined according to the desired thickness of the coating 18 on the surface 16.
- the method then comprises a step f) of manual rotation by an operator of the tool 20 and of the rotor 42 inside the casing 10, thanks to the flywheel 82, so as to spread the resin with the rollers 80 on the surface 16 of housing 10.
