TURBOMACHINE WITH OPTIMIZED ARRANGEMENT FOR FASTENING A ROTATING SHAFT BEARING. BOLT FOR SUCH A TURBOMACHINE

摘要

Turbomachine comprising a shaft, a bearing for holding the shaft, comprising an outer ring, a support (20) for said bearing, on a flange (36) of which the outer ring is fixed by bolts; each bolt having a holding screw (146) and a nut (150) screwed together; the turbomachine further comprising, for each bolt, holding means in position (158) for the holding screw, able to maintain the latter in a fixed position relative to the bearing support or to the outer ring, even in the absence the nut (150). Bolt for such a turbomachine. The head of the retaining screw with the holding means can be of small dimensions, whereby the fixing of the flange on the bearing support and therefore the weight of this attachment can be optimized.
