Abstract

A UNA BOMBA GEROTOR PUEDE ASIGNARSE UNA LONGITUD AXIAL ESPECIALMENTE CORTA, FIJANDO EL EJE PRINCIPAL DEL CUERPO (EN VEZ DE DESPLAZARLO POR EL CUERPO) Y DESPLAZAR EL ROTOR EN EL EJE (EN VEZ DE SUJETAR EL ROTOR AL EJE). LA FIGURA 3 MUESTRA UNA CONFIGURACION EN EL QUE EL ENGRANAJE 24 TRANSMITE FUERZA A LA BOMBA Y TIENE UNA EXTENSION AXIAL 38 DESPLAZADA EN EL EJE FIJO 18 Y ESTA CHAVETEADA EN 46 AL ROTOR QUE RODEA LA EXTENSION, POR LO QUE SOLO ES SE SUJETA Y DESPLAZA INDIRECTAMENTE POR EL EJE. 14 REPRESENTA EL ANILLO EN EL QUE NORMALMENTE GIRA EL ROTOR EN EL MODO DE BOMBEO GEROTOR CONVENCIONAL.A SPECIALLY SHORT AXIAL LENGTH CAN BE ASSIGNED TO A GEROTOR PUMP, ATTACHING THE MAIN SHAFT OF THE BODY (INSTEAD OF MOVING IT BY THE BODY) AND SHIFTING THE ROTOR ON THE SHAFT (INSTEAD OF HOLDING THE ROTOR TO THE SHAFT). FIGURE 3 SHOWS A CONFIGURATION IN WHICH GEAR 24 TRANSMITS FORCE TO THE PUMP AND HAS AN AXIAL EXTENSION 38 OFFSET ON FIXED SHAFT 18 AND IS KEYRED AT 46 TO THE ROTOR WHICH SURROUNDS THE EXTENSION, SO IT IS ONLY SUPPORTED AND DISPLACED INDIRECTLY THROUGH THE AXIS. 14 REPRESENTS THE RING ON WHICH THE ROTOR NORMALLY ROTATES IN CONVENTIONAL GEROTOR PUMPING MODE.
