Definitions
- the invention relates to the field of friction welding in the process of manufacturing turbine engine components (compressors, turbines, etc.) and more particularly to an inertial friction welding (IF) process between high pressure compressor stage discs.
- the present invention therefore has the main purpose of providing an FI welding process that overcomes this disadvantage.
- an inertial friction welding process F1 of two parts of a turbomachine rotating subassembly at least one of which has at its periphery a plurality of hook teeth for anchoring feet of blade and in which one of two parts to be welded to one another is held by a clamp and rotated by a motor and the other of the two parts to be welded is held by a ring gear of torque recovery mounted in a carriage movable in translation, characterized in that to avoid any formation of cracks at the hooks of said teeth during welding, it is intended to cover said plurality of hook teeth damping means adapted to shift the frequency vibratory response of said hooks and thus create a damping.
- this damper assembly shifting in frequency the vibration response and damping the hooks, it ensures a sufficient energy absorption to avoid the creation of cracks on the disc.
- said damping means comprise seven adjacent damping sectors completely covering said plurality of hooked teeth and each covering an angle of about 51 degrees.
- each of said damping sectors comprises two lateral flanks conforming to the circumference of the disc and resting on the lateral edges of the teeth via a first viscoelastic gum, two upper flanges of these flanks resting on two clamping plates. in contact with the upper edges of the teeth via a second viscoelastic gum.
- said plates are held tight by screws compressing spring means disposed between these two plates and acting as a return spring once they are loosened.
- said damping means comprise an individual damper mounted on each of the teeth of said set of hooked teeth.
- said individual damper comprises a first blade, one end of which is terminated by a flange cooperating with one of the two hooks of a tooth and a second blade, one end of which is terminated by a flange cooperating with the other of the two hooks of said tooth, the other end of said first and second blades being secured to each other by fastening means.
- said first blade has length and width substantially corresponding to the length and width of a tooth and said second blade has a length substantially corresponding to the height of a tooth and a width substantially corresponding to the width of a tooth.
- said first and second blades are covered on their inner face in contact with said teeth by viscoelastic gums.
- FIGS. 1A and 1B are detailed sectional views respectively of the mandrel and the carriage of an inertial friction welding machine called FI suitable for implementing the method of the invention;
- FIGS. 2 and 2A to 2C illustrate a first embodiment of damping means implemented in the method of the invention.
- FIGS. 3A and 3B illustrate a second embodiment of damping means implemented in the method of the invention.
- FIGS. 1A and 1B respectively represent the mandrel and the carriage of an FI inertial friction welding machine capable of carrying out the process according to the invention of welding FI of two stages of high pressure compressor discs; a turbomachine.
- a turbomachine a turbomachine
- the machine 10 consists essentially of a part of a mandrel 12 coupled to flywheels 14 and in which a 26 of the two parts of the subassembly to be welded is held by a clamp 16 and rotated by a motor 18 ( Figure 1A) and on the other hand a carriage 20 movable in translation and on which is mounted a sole 22 in the toothed gear ring (or the jaw 24) which is held the other 28 of the two parts of the sub-assembly to be welded.
- the operating principle of this machine is based on the fact that the heat required for welding is generated by the friction between two moving parts relative to each other.
- the motor 18 drives the mandrel 12 in rotation allowing an accumulation of kinetic energy in the flywheels 14 until the motor has reached a predetermined speed allowing its disengagement.
- the advance of the carriage 20 is then actuated causing a contact of the two parts of the subassembly 26, 28 to be welded.
- the friction caused by the rotation and the axial pressure of these two parts will cause a heating increasing temperature which in a relatively short time will reach the temperature (forging temperature) required for welding.
- FIG. 1A shows a mandrel 12 whose clip 16 clamps a high-pressure titanium-based stage disk of an aircraft engine having at its periphery a plurality of hook teeth for anchoring feet. of blades in the compressor and Figure 1B shows a carriage 20 whose jaw 24 clamps all adjacent disks of the other titanium-based stages of a high pressure compressor of an aircraft turbine engine.
- FIG. 1A shows a mandrel 12 whose clip 16 clamps a high-pressure titanium-based stage disk of an aircraft engine having at its periphery a plurality of hook teeth for anchoring feet. of blades in the compressor
- Figure 1B shows a carriage 20 whose jaw 24 clamps all adjacent disks of the other titanium-based stages of a high pressure compressor of an aircraft turbine engine.
- this is only an example of welded discs among many other conceivable.
- the relative rotational movement of the discs to be welded and the associated friction generate vibrations to which the structure of these discs, the tool and the machine respond in the form of a structural vibratory response.
- These vibrations which depend on the geometry of the discs to be welded, the conditions for holding in position, the welding parameters and the material or materials these discs, may lead, according to their frequency, the initiation of cracks on the discs, especially at the hooks of the teeth.
- dampen these vibrations by covering the plurality of hook teeth with damping means 30, 40 in order to frequency shift the vibration response of the hooks of these teeth and thus prohibit any initiation of cracks.
- Figures 2, 2A, 2B and 2C illustrate a first embodiment in which the damping means 30 are formed of several damping sectors evenly distributed around the disk.
- the damping means 30 are formed of several damping sectors evenly distributed around the disk.
- the illustrated example corresponding to a 70-tooth high-pressure compressor stage disk 3, there are seven adjacent sectors each extending about 51 degrees, each sector covering ten teeth.
- Each shock absorbing sector has two curved lateral flanks 32, 34 in the form of ⁇ (inverted L), conforming to the circumference of the disc and intended, when tightened against each other, to bear against the lateral edges of the teeth.
- ⁇ inverted L
- the two upper flanges 32A, 34A of these flanks resting on two clamping plates 36, 38 which are also curved along the circumference of the disc and in contact with the upper edges of the teeth via a second viscoelastic gum 40B .
- the plates are held tight by screws 42 compressing spring means 44 disposed between these two plates and acting as a return spring once these loosened. Screws 46 maintain the lateral flanks on the clamping plates.
- FIGS. 3A and 3B illustrate a second embodiment in which the damping means 50 are individualized and each cover a tooth 52 of the disk.
- Each individual damper thus comprises a first blade 54 whose length and width substantially correspond to the length and width of a tooth and whose one end is terminated by a flange 54A intended to cooperate with the one 52A of the two hooks of this tooth, preferably the hook behind the tooth, and a second blade 56 of a length corresponding substantially to the height of the tooth but of the same width as the first and whose one end is terminated by a flange 56A intended to cooperate with the other 52B of the two hooks of the tooth (the one in front of the tooth accessible on the front of the carriage), the second sloped ends 54B, 56B of these first and second blades being secured to each other by fastening means, typically a screw-nut assembly 58
- fastening means typically a screw-nut assembly 58
