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