ABSTRACT:
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.
