Abstract
PURPOSE: To prevent the leakage of oil by securing proper truck depth by more shortening the central interval of gear hole than that of bearing hole.
CONSTITUTION: The center Oe of the gear hole is deviated toward the center O' of the other bearing hole against the center O of the bearing hole; that is, the interval between the centers Oe and Oe' of both gear holes is made shorter than that between the centers O and O' of the bearing holes. When driving the said pump, because the center of the gear shaft is deviated toward Os, the relation between the gear hole centered at Oe and the addendum circle (a) of the gears 2 and 3 forms a gear truck having the depth (t) in the range of rotation angle θe. Thus, the leakage of high-pressure oil from the addendum of the gear can be exactly prevented.
