Abstract

UN COJINETE DE EMPUJE O SUSTENTACION AXIAL, UTILIZABLE ESENCIALMENTE EN MAQUINAS ROTATIVAS LENTAS, DEBE PRESENTAR CON UN DIAMETRO MINIMO, EN LO POSIBLE UNA SUPERFICIE DE RODADURA DE SOPORTE GRANDE, Y AL MISMO TIEMPO TENER PROPIEDADES OPTIMAS DE RODADURA, ASI COMO UNA DURABILIDAD LARGA DURANTE UN FUNCIONAMIENTO NORMAL, COMO TAMBIEN UNAS CARACTERISTICAS DE RODADURA DE EMERGENCIA BUENAS EN EL CASO DE FALTA DE LUBRIFICACION. A TAL EFECTO UN CUERPO BASICO 2 SOPORTA P.EJ UN ANILLO O UN SEGMENTO ANULAR, PATINES DE DESLIZAMIENTO 3, DISPUESTOS EN DIRECCION CIRCUNFERENCIAL Y EN DIRECCION RADIAL DISTRIBUIDAS POR IGUAL, SOBRE LAS CUALES SE APOYA UNA SUPERFICIE OPUESTA PLANA A TRAVES DE UNA PELICULA LUBRIFICANTE PORTADORA. LOS PATINES DE DESLIZAMIENTO PRESENTAN, AL MENOS EN PLANTA, CASI UNA FORMA CUADRANGULAR, Y ESTAN CONCEBIDAS EN CIRCULOS PARCIALES PREDETERMINADOS D0, D1, D2 ... DX DEL CUERPO BASICO 2, SITUADOS DE FORMA CONGRUENTA ENTRE SI. LA LONGITUD DEL CANTO DEL PATIN DE DESLIZAMIENTO 3 AUMENTA ENDIRECCION DESDE EL INTERIOR HACIA EL EXTERIOR PROPORCIONALMENTE, DE ACUERDO CON EL AUMENTO DE LOS DIAMETROS DE LOS CIRCULOS PARCIALES D0, D1, D2 ... DX, Y LOS PATINES DE DESLIZAMIENTO CONTIGUOS ENTRE SI, ESTAN LIMITADOS UNO CONTRA OTRO, RESPECTIVAMENTE POR MEDIO DE PERFILES DE RANURAS O MUESCAS 7, 7'', 7''''. DOS GRUPOS 7'' Y 7'''' DE LOS PERFILES DE LAS RANURAS O MUESCAS 7 TIENEN UN DESARROLLO EN FORMA DE ESPIRAL CURVADO, Y LA DIRECCION DE SU CURVATURA SE HA PREVISTO A TAL EFECTO EN SENTIDO OPUESTO. PRESENTAN PREFERENTEMENTE RESPECTIVAMENTE LA FORMA DE UNA ESPIRAL LOGARITMICA.
