A bearing assembly (20) for a pump (12), e.g., an internal or external gear pump includes a journal bearing block (20) having a length, a width, and an axial centerline (CL′) passing through a center of the journal bearing block (20) with respect to the length. The journal bearing block (20) includes at least two journal bearing bores (21), the journal bearing bores (21) each having a center (C), wherein a bearing bore centerline (CL) extends between the centers (C) of the journal bearing bores (21) and in parallel with the bearing bore centerline (CL). The bearing bore centerline (CL) is offset with respect to the width of the journal bearing block (20) and the axial centerline (CL′). The bearing assembly (20) is particularly applicable to gear pumps, such as external gear pumps for fuel applications.
A bearing for a pump comprising:
A bearing for a gear pump comprising:
A gear pump comprising:
A repair method for a worn gear pump comprising a pump housing, at least two intermeshing gears, at least two rotating shafts supported within at least one journal bearing block having at least two journal bearing bores, wherein said at least one journal bearing block has a length, a width, and an axial centerline passing through a center of said at least one journal bearing block with respect to said length, said method comprising offsetting said at least two journal bearing bores with respect to either an inlet side or an outlet side of said pump, wherein said journal bearing bores each have a geometric center and a bearing bore centerline extending between said centers of said journal bearing bores;
