LUBRICATING MECHANISM OF OIL PUMP

摘要

A lubrication structure of an oil pump is provided to supply the lubricant from an opening of an outlet to both ends of a first sliding surface by disposing an opening of an inlet in the center of the first sliding surface along the axial direction of a driving shaft. A lubrication structure of an oil pump(30) is composed of a driving shaft(31) installed in parallel to an input shaft(17); a bearing(32) having a first sliding surface(32a) for supporting rotatively an outer peripheral surface of the driving shaft; a rotor(33) rotated by the driving shaft to raise and send the lubricant of a suction oil chamber(36) to a discharge oil chamber(37); and a lubricant hole(50) for communicating the discharge oil chamber and the first sliding surface. The rotation of the input shaft is accelerated and transmitted to the driving shaft.
