Abstract

The turbomachine has ball bearings (112, 113) mounted around a countershaft (116) that is mounted around a high pressure body trunnion (110), where the countershaft is provided with a bevel pinion (142) that is gripped with a bevel pinion of an additional shaft (144). An integration unit rotatably integrates the countershaft. An annular locking part (128) is elastically deformed between a position in which locking units are engaged in units i.e. teeth, of the nut and a position in which the locking units are disengaged from the units of the nut.
