<p>The turbomachine has an axially fixed transmission gear with axially directed gear face rotationally coupled to shaft (1). A collar (10) has axially directed collar face (17,17') that is spaced from the gear face by a clearance equal to more than the predetermined axial displacement with fixed axially on the shaft. The gear face and collar face are engaged each other so as to limit axial movement of the shaft on failure of one of the bearings (6,6') and axial overtravel of the shaft.</p> |
