摘要： The invention provides a device for supporting and recentering a shaft (2) after decoupling. The device comprises an annular support (4) surrounding the shaft (2), a bearing (5) secured to the annular support (4) and having an inner ring (9) which is spaced apart from the shaft by clearance J. The inner ring (9) has two webs or tenons (14a, 14b) that are normally held to the periphery of two troughs (16a, 16b) carried by the shaft (2). Two sets of balls (28a, 28b) normally bear against the bottoms of indentations (25, 26) formed facing one another in the adjacent radial walls of the troughs (16a, 16b) and of the inner ring (9). Resilient means (26) tend to urge the troughs (16a and 16b) towards each other. In the event of the webs or tenons (14a, 14b) breaking due to a large unbalance, the balls (28a, 28b) roll on the walls of the indentations (25, 26) and move the troughs (16a, 16b) apart from each other. The resilient mans (20) tend to bring the balls (28a, 28b) back towards the bottoms of the indentations and to recenter the shaft (2) relative to the inner ring (9).
