Method for assembling turbomachine parts and assembly used during such a method
A method for assembly of a first turbomachine part with at least one second turbomachine part, including an injection of a vulcanisable elastomer, preferably a silicone that can be vulcanised at ambient temperature called an RTV silicone, in an injection zone at the junction between the first and the second parts; local heating of the injection zone so as to vulcanise the vulcanisable elastomer.
1. A method for assembly of a first turbomachine part with a second turbomachine part, comprising:
injecting a vulcanisable elastomer in an injection zone at a junction between the first and second turbomachine parts; and
heating only of the injection zone so as to vulcanise the vulcanisable elastomer,
wherein the heating only of the injection zone is implemented using an assembly for assembling the first and second turbomachine parts, the assembly comprising a support and a ring, the support comprising an annular support wall for the ring, the ring being formed from a first material and a second material, the first material being a thermal insulating material and the second material being a heat conducting material.
2. The assembly method according to claim 1 , wherein the first and second turbomachine parts are two annular parts configured to form a turbomachine guide vane after assembly.
3. The method according to claim 1 , wherein the assembly comprises a heating system comprising a heating zone and that is associated with the support such that the heating zone is facing the injection zone while the heating step is being performed.
4. The method according to claim 3 , wherein the assembly also acts as an assembly support used during the injecting of the vulcanisable elastomer.
5. The method according to claim 1 , wherein the heating step is implemented with a heating element previously placed on the first and second turbomachine parts close to the injection zone.
6. The method according to claim 1 , wherein the heating is implemented using a remote heating system.
7. The method according to claim 6 , wherein the remote heating system is selected among the group consisting of a hot air blowing system at the injection zone, laser radiation and microwave radiation.
8. The method according to claim 1 , wherein the vulcanisable elastomer is a silicone that can be vulcanised at ambient temperature called an RTV silicone.
9. A method for assembly of a first turbomachine part with at least one second turbomachine part, comprising:
injecting a vulcanisable elastomer in an injection zone at a junction between the first and second turbomachine parts; and
applying local heating at first portions of the first and second turbomachine parts, the first portions comprising the injection zone so as to vulcanise the vulcanisable elastomer, no heating being applied to second portions of the first and second turbomachine parts,
wherein the local heating step at first portions of the first and second turbomachine parts is implemented using an assembly for assembling the first and second turbomachine parts, the assembly comprising a support and a ring, the support comprising an annular support wall for the ring, the ring being formed from a first material and a second material, the first material being a thermal insulating material and the second material being a heat conducting material.
10. A method for assembly of a first turbomachine part with a second turbomachine part, comprising:
injecting a vulcanisable elastomer in an injection zone at a junction between the first and second turbomachine parts; and
heating only of the injection zone so as to vulcanise the vulcanisable elastomer,
wherein the vulcanisable elastomer is a silicone that can be vulcanised at ambient temperature called an RTV silicone, and
wherein the heating only of the injection zone is performed using an assembly comprising a support and a ring, the support comprising an annular support wall for the ring, the ring being formed from a first material and second materials, the first material being a thermal insulating material and the second material being a heat conducting material.
