Abstract

Una disposición de rodamiento hidrodinámico (10) para un eje que gira (12), la disposición (10) incluye una carcaza (14) en donde se provee un soporte de eje (16) con una abertura a través de la cual se extiende el eje (12), habiendo un espacio entre el soporte de eje (16) y el eje (12), el soporte de eje (16) incluye al menos un canal (22a, 22b) a través de eso, el cual se extiende generalmente en forma axial del eje (12) desde un primer lado del soporte de eje (15) a una cámara (28) provista en la carcaza (14) en un segundo lado del soporte de eje (16) de manera tal que el liquido en el primer lado del soporte de eje (16) se puede comunicar con la cámara (28) en el segundo lado del soporte de eje (16) y de este modo pasar dentro del espacio entre el eje (12) y el soporte de eje (16) desde tanto el primer lado del soporte del eje (16) como desde el segundo lado del soporte de eje (16) a través del canal (22a,22b) y la cámara (28), el liquido entre el eje (12) y el soporte de eje (16) mantiene el espacio entre el eje (12) y el soporte de eje (16) y provee un rodamiento hidrodinámico para el eje (12).A hydrodynamic bearing arrangement (10) for a rotating shaft (12), the arrangement (10) includes a housing (14) where a shaft support (16) is provided with an opening through which the shaft (12), with a space between the shaft support (16) and the shaft (12), the shaft support (16) includes at least one channel (22a, 22b) therethrough, which generally extends axially of the shaft (12) from a first side of the shaft support (15) to a chamber (28) provided in the housing (14) on a second side of the shaft support (16) such that the liquid in The first side of the axle support (16) can communicate with the chamber (28) on the second side of the axle support (16) and thus pass into the space between the axis (12) and the axle support ( 16) from both the first side of the shaft support (16) and from the second side of the shaft support (16) through the channel (22a, 22b) and the chamber (28), the liquid between the shaft (12) and the support of shaft (16) maintains the space between the shaft (12) and the shaft support (16) and provides a hydrodynamic bearing for the shaft (12).
