Abstract

EL INVENTO CONSISTE EN UN COJINETE DESLIZANTE AERODINAMICO PARA EJES (1) CIRCULANDO A ELEVADAS VELOCIDADES DE GIRO, CON UN DEPOSITO DE COJINETE (4), MOSTRANDO UN ORIFICIO (3) CILINDRICO Y UNA ESTRUCTURA (2) AMORTIGUADORA, ELASTICA, TANGENCIAL, MOSTRANDO SEGMENTOS (2" O 2A), QUE SE APOYA EN VARIOS LUGARES PERIFERICOS DEL DEPOSITO DE COJINETE (4), Y QUE FORMA, CON EL EJE (1), UNA RANURA DE MARCHA (6) CONVERGENTE MULTIPLE, Y CON EL DEPOSITO DE COJINETE (4), RANURAS DE AMORTIGUAMIENTO (5). PARA QUE SEAN SUFICIENTES LAS MENOS PIEZAS POSIBLES DE CONSTRUCCION Y EL MENOR ESPACIO DE CONSTRUCCION RADIAL, SE PROPONE QUE LOS SEGMENTOS (2" O 2A) TENGAN LA ESTRUCTURA DE SEGMENTOS DE MANGUITO ELASTICOS, DE PAREDES FINAS, CON FUERZAS DE PARED REGULAES O PERFILADAS Y BAJO VALOR DE FROTAMIENTO, Y QUE SIMULTANEAMENTE SEAN ELEMENTOS DE AMORTIGUACION Y ELASTICIDAD.
