20080273825 | Sliding Bearing With Different Sets of Cavities - A sliding bearing, e.g. journal bearing, including at least two bearing elements the bearing surfaces of which are slidably supported with respect to each other. At least one of the surfaces is provided with a first type of cavity which may comprise a lubricating substance, the first type of cavity being defined by a specific range of geometric properties. At least one surface is provided with at least a second type of cavity which may comprise a lubricating surface, the second type of cavity being defined by geometric properties which are different from the geometric properties of the first type of cavity. | 11-06-2008 |
20100219038 | FREEWHEEL BEARING DEVICE WITH TORQUE LIMITER - The invention concerns a freewheel bearing device including an outer element and inner element arranged inside the outer element, and a free wheel provided with at least a wedging element, arranged between the inner element and the outer element to allow a free rotational movement in one direction between the outer element and the inner element and for transmission of a torque in the other direction between the outer element and the inner element, the free wheel including a ring provided with a cylindrical inner surface and a cylindrical outer surface, substantially aligned on a radial plane perpendicular to the axis of rotation of the device, and a torque limiting member adapted to limit the torque transmitted by the free wheel, the torque limiting member being arranged radially between said ring and the outer element or the inner element in contact with said ring and said element. | 09-02-2010 |

20140354098 | Auxiliary bearing for magnetically suspended rotor system - An assembly that includes a rotating shaft supported with respect to a stationary housing by at least one active magnetic bearing presenting a mean radial air gap and at least one auxiliary bearing having a bushing fixed to the housing and a sleeve fixed on the rotating shaft. The bushing and the sleeve have opposite surfaces that define a clearance (E2) which is less than the mean radial air gap (E1). The bushing and the sleeve each exhibit symmetry around a longitudinal axis of the shaft and have different profiles in a longitudinal cross-section including the longitudinal axis to optimize the contact pressure distribution when the rotating shaft lands on the auxiliary bearing. | 12-04-2014 |
20150028706 | AUXILIARY BEARING OF THE BALL BEARING TYPE FOR A MAGNETICALLY SUSPENDED ROTOR SYSTEM - An assembly includes a rotating shaft supported with respect to a stationary housing by at least one active magnetic bearing presenting a mean radial air gap and at least one auxiliary bearing having first and second coaxially arranged annular surfaces is provided. One of the first and second coaxially arranged annular surfaces defines a clearance (E | 01-29-2015 |
20150260221 | ROTARY MACHINE, BEARING AND METHOD FOR MANUFACTURING A ROTARY MACHINE - A rotary machine, comprising: a stator assembly and a rotor assembly centered on a central axis; a magnetic bearing; and an auxiliary bearing including a first ring held in the stator assembly and a second ring delimiting a gap radially to the central axis relative to the rotor. The second ring is not rotating around the central axis in a primary operation mode and is dragged in rotation around the central axis in a secondary operation mode. The rotary machine includes a monitoring system for detecting a transition from the primary operation mode to the secondary operation mode. The monitoring system comprises a target formed on the second ring and a sensor unit fixed relative to the stator assembly. A bearing and a method for manufacturing a rotary machine are additionally disclosed. | 09-17-2015 |
