As seen from Figure 3, owing to two compensate and insert the length of the isometric straight tubes in shoe cream room 103 in oilholes 109 and be not more than the radius of shoe cream room 103 in planetary gear bearing pin 4, and oil-in is positioned at the end of straight tube, during planet carrier 3 operates, if the lubricating oil liquid level in planetary gear bearing pin 4 in shoe cream room 103 is less than the oil-in of straight tube, lubricating oil is impossible to enter and compensates oilhole 109, and now sliding bearing 2 will be unable to obtain lubricating oil by described compensation oilhole 109.Therefore, when the amount of being actually inserted into of straight tube is less than the radius of shoe cream room 103 in planetary gear bearing pin 4, the liquid level that the lubricating oil liquid level in shoe cream room 103 is corresponding with the amount of being actually inserted into of straight tube is exactly the minimum critical oil bit line meeting compensation oilhole 109.
In real work, under gear-box normal running conditions, Oil pump electrical machinery normally works, gear-box fuel feeding is sufficient, forced feed lubrication oil duct can be shoe cream room 103 make-up oil in planetary gear pivot pin 4 by oil duct 102 and 101, and provides lubrication by oilhole 111 for sliding bearing 2, provides lubrication by radial direction oil hole 105 and axial oilhole 106 for plain thrust bearing 6, meanwhile, two compensation oilholes 109 also synchronize to provide lubrication into sliding bearing 2.
Under gear-box dry run condition, or under blower fan power-off operating mode, when Oil pump electrical machinery can not continue fuel feeding, the mechanical pump being equipped with now by gear-box is only the lubricating oil replenishing that shoe cream room 103 in planetary gear bearing pin 4 provides a small amount of, cause the lubricating oil liquid level in shoe cream room 103 progressively to decline, will stop providing lubrication for sliding bearing 2 higher than compensation oilhole 109 when liquid level is less than minimum critical oil bit line.Owing to the aperture of oilhole 111 and radial direction oil hole 105 and axial oilhole 106 is the least, after oilhole 109 stopping offer lubrication is provided, lubrication oil consumption in shoe cream room 103 slows, its consumption can reach balance with the lubricating oil replenishing amount that the mechanical pump that gear-box is equipped with provides completely, thus maintains gear-box to run well under the airport logistic park operating mode of idle running or blower fan power-off.
Owing to the lubricating oil supply system of gear-box is equipped with filtration system, the lubricating oil of the cleaning after filtration can avoid oil sump to pollute the damage causing each sliding bearing sliding surface.
