Abstract
Dispositivo comprendente una base, un alberino ritto su una parte centrale della base, un elemento (4) fissato sull'alberino, due piastre di spinta (3) fissate alle superfici terminali dell'elemento (4), e un manicotto (6) supportato a rotazione dalle piastre (3) e dal manicotto (6), in cui un supporto idrodinamico radiale è formato dall'elemento (4) e dal manicotto (6), supporti idrodinamici di spinta sono formati dalle due parti terminali del manicotto (6) e dalle piastre (3), un gas è impiegato per generare pressione dinamica nei supporti di spinta, il supporto radiale ha un gioco stretto, una parte smussata è prevista sulla periferia esterna di ciascuna estremità dell'elemento (4) e un'altra parte smussata è prevista sulla periferia interna di ciascuna estremità del manicotto (6) creando un gap d'aria (13) a ciascuna estremità assiale del supporto radiale, un liquido lubrificante è impiegato per generare pressione dinamica nel supporto radiale, piccoli fori (8) sono previsti nella superficie periferica dell'elemento (4), e il lubrificante è a tenuta nel gioco del supporto grazie ai gap d'aria (13).Device comprising a base, a spindle standing on a central part of the base, an element (4) fixed on the spindle, two thrust plates (3) fixed to the end surfaces of the element (4), and a sleeve (6) supported rotationally from the plates (3) and from the sleeve (6), in which a radial hydrodynamic support is formed by the element (4) and by the sleeve (6), hydrodynamic thrust supports are formed by the two end parts of the sleeve (6) and from the plates (3), a gas is used to generate dynamic pressure in the thrust supports, the radial support has a tight play, a chamfered part is provided on the outer periphery of each end of the element (4) and another part chamfered is provided on the internal periphery of each end of the sleeve (6) creating an air gap (13) at each axial end of the radial support, a lubricating liquid is used to generate dynamic pressure in the radial support, small holes (8) are previst i in the peripheral surface of the element (4), and the lubricant is tight in the play of the support thanks to the air gaps (13).
