FORCE FEED MECHANISM OF LUBRICATING OIL AND SCREW COMPRESSOR HAVING THE FORCE FEED MECHANISM

摘要

PROBLEM TO BE SOLVED: To add a function of an oil pump to a transmission of a working machine.;SOLUTION: This force feed mechanism of lubricating oil stores a pump gear 61 rotating by meshing with one of gears in a gear chamber of the transmission 5, and forms a pressurizing chamber 62 via a rotation allowable minimum clearance of both the gears on the outer periphery and both side surfaces of both the gears over a predetermined range before reaching a meshing position e from a meshing position e of both the gears, and can deliver the lubricating oil in the gear chamber to a cooling pipe system via a delivery port by meshing rotation in the delivery port direction of both the gears by arranging the delivery port 67 of the lubricating oil on a sidewall 64 of the pressurizing chamber immediately before the meshing position e of both the gears.;COPYRIGHT: (C)2009,JPO&INPIT
