摘要： A rotor drive shaft assembly (32) for use in a centrifugation system. The rotor drive shaft (34) has a bearing material configured as a sleeve (38) and mounted on the inside wall (41) of a spindle hub (30) with a clearance (39) existing between the sleeve and a housing (36) that surrounds the lower base of the shaft. When the rotor and hub experience radial displacement at a critical speed, the sleeve makes contact with the housing in order to limit further radial displacement. Alternatively, the sleeve can be mounted on the outside of the housing with the clearance existing between the sleeve and the spindle hub, with the sleeve making contact with the spindle hub at the critical speed in order to limit further radial displacement. In another embodiment, a support tube is provided which surrounds the lower portion of the shaft with a clearance existing between the shaft and the support tube. When the shaft experiences radial displacement at the critical speed, the shaft makes contact with the support tube which limits further radial displacement.

摘要： A bearing device for a high speed rotary shaft is provided with a functional bearing disposed on a shaft which is supported rotatably on a housing by a pair of bearings (5), and capable of supporting rotatably the shaft, a rotation sensor for detecting the speed of revolution of the shaft and a controller for changing the functional bearing to a shaft supporting state in response to a rotation detection signal from the rotation sensor representing that the speed of revolution of the shaft is above a predetermined level. When the shaft rotates at a low speed, the functional bearing is set to a free state and the shaft is supported at two points on the housing by the pair of bearings (5) alone. When the shaft rotates at a high speed, the functional bearing is operated so that the shaft is supported at three points on the housing to prevent the occurrence of deflection of the shaft.

摘要： A water lubricated bearing assembly having a plurality of circumferentially spaced first set of bearing elements with substantislly,flat surfaces and water courses therebetween supporting a shaft for rotation. Certain ones or all of such bearing elements support a second set of bearing element that are moveable radially into supporting engagement with the shaft such that either the first set or the second set of bearing elements are the prime supports for the shaft and wherein such first and second set of bearing elements have different coefficient of friction.

摘要： Le dispositif selon l'invention prévu pour un groupe motopompe pourfluide sous pression, comprenant une roue à aubes (2) solidaire d'un arbre vertical (1) entraîné en rotation, la jante (3) de la roue prenant normalement appui sur un palier hydrostatique (4), est constituté par une douille (10) logée coaxialement à l'arbre (1) dans un espace ménagé à cet effet entre l'arbre et la paroi interne (9) du corps (8) de la pompe. La douille a un diamètre interne légèrement supérieur du diamètre de l'arbre de manière à constituer pour l'arbre un palier hydrodynamique en cas de défaillance du palier hydrostatique (4).
