Abstract

Una bomba hidráulica incluye un mecanismo de bomba que tiene un eje impulsado. El eje impulsado está conectado a un eje de entrada por un acoplamientoflexible tal como una conexion ranurada. Un alojamiento se extiende completamente alrededor del ejeimpulsado, y un sello de alta presion está dispuesto entreel alojamiento y el eje de entrada. Un cojinete de empuje lleva las fuerzas axiales hidráulicas del eje de entrada al alojamiento. Esta disposicion proveefuerzas hidráulicas balanceadas sobreambos extremos del eje impulsado, reduciendo así la friccion y el desgaste. La bomba hidráulica mantiene fuerzas axialesequilibradas sobre el mecanismo de bombeo aun en el caso de altas presiones de entrada y salida de bomba y comprende un mecanismode bomba que comprende un ejeque comprende un extremeo interno y un extremo externo; un eje de entrada que comprende un extremo interno y un extremo externo; un acoplamiento flexibleacoplado entre el extremo interno del eje de entrada y el extremoex terno del eje impulsado; un alojamiento dispuesto alrededor del acoplamiento flexible; elextremo externo del eje impulsado, y el extremo interno del eje de entrada; un sello dispuesto entre el alojamiento y el eje de entrada; y un cojinetedeempuje d ispuesto entre el alojamiento y el eje de entrada; transmitiendo dicho acoplamiento flexible presion de fluido dentro del alojamiento hacia el extremoexterno del eje impulsado con lo cual la presion de fluido en el extremo externo del ejeimpulsado t iende a equilibrar la presion de fluido sobre el extremointerno del eje impulsado.A hydraulic pump includes a pump mechanism that has a driven shaft. The driven shaft is connected to an input shaft by a flexible coupling such as a grooved connection. A housing extends completely around the driven shaft, and a high pressure seal is disposed between the housing and the input shaft. A thrust bearing carries the hydraulic axial forces of the input shaft to the housing. This arrangement provides balanced hydraulic forces over both ends of the driven shaft, thereby reducing friction and wear. The hydraulic pump maintains balanced axial forces on the pumping mechanism even in the case of high pump inlet and outlet pressures and comprises a pump mechanism comprising an axle comprising an internal end and an external end; an input shaft comprising an inner end and an outer end; a flexible coupling coupled between the inner end of the input shaft and the outer end of the driven shaft; a housing arranged around the flexible coupling; the outer end of the driven shaft, and the inner end of the input shaft; a seal disposed between the housing and the input shaft; and a thrust bearing disposed between the housing and the input shaft; said flexible coupling transmitting fluid pressure inside the housing towards the outer end of the driven shaft whereby the fluid pressure at the outer end of the driven shaft tends to balance the fluid pressure on the inner end of the driven shaft.
