Turboshaft engine e.g. turbojet, for aircraft, has cylindrical sleeve whose downstream ends include axial support units on which pivot is supported due to differential thermal dilations in direction opposed to upstream ends of sleeve

The engine has a low pressure module and a high pressure module, where the low pressure module comprises a compressor and a turbine whose rotors are connected by a drive shaft. The drive shaft extends inside a cylindrical sleeve (26') whose upstream ends (28) and downstream ends (30') are...

Beschreibung
Zusammenfassung:	The engine has a low pressure module and a high pressure module, where the low pressure module comprises a compressor and a turbine whose rotors are connected by a drive shaft. The drive shaft extends inside a cylindrical sleeve (26') whose upstream ends (28) and downstream ends (30') are connected to a pivot (20). The downstream ends of the sleeve include axial support units or an external edge on which the pivot is supported due to differential thermal dilations in a direction opposed to the upstream ends of the sleeve for applying tractive force to the sleeve. Turbomachine (10), comprenant un module haute pression comportant un compresseur (14) et une turbine (16) qui entourent un arbre de transmission qui s'étend à l'intérieur d'un fourreau cylindrique (26) ayant une extrémité amont (28) filetée et vissée dans un filetage d'un tourillon du compresseur haute pression et une extrémité aval (30) qui comprend des moyens (32, 34) d'appui axial sur lesquels un tourillon de la turbine haute pression est destiné à venir en appui en direction de l'aval pour appliquer au fourreau un effort de traction en fonctionnement, du fait des dilatations thermiques différentielles.
