Oil is filtered by first filter 11, and the lubricating oil filtered by first filter 11 is defeated by first oil hose
Send to the oil inlet A1 on first gear pump 13, first gear pump 13 and work, will enter under the drive of the 3rd spur gear 18
Lubricating oil in first gear pump 13 is pumped on 13 by the oil outlet D1 removal of lubricants on first gear pump 13, first gear
The lubricating oil of oil outlet D1 discharges enters the second tooth by the oil inlet B2 on second oil hose and second gear pump 14
Wheel pump 14, second gear pump 14 work under the drive of the 3rd spur gear 18, will enter the lubricating oil in second gear pump 14
By the oil outlet C2 removal of lubricants on second gear pump 14, the lubricating oil of the oil outlet C2 discharges on second gear pump 14 is defeated
Send to cooler 20；
When the oil level in arm body oil pocket 2 is higher, the lubricating oil of the high-order inlet port of arm body oil pocket 2 passes through the second filter 12
Filtered, the lubricating oil by the filtering of the second filter 12 is delivered on second gear pump 14 by the 3rd oil hose
Oil inlet A2, second gear pump 14 the 3rd spur gear 18 drive under work, will enter second gear pump 14 in profit
For lubricating oil by the oil outlet D2 removal of lubricants on second gear pump 14, second gear pumps the lubrication of the oil outlet D2 discharges on 14
Oil enters first gear pump 13, first gear pump 13 by the oil inlet B1 on the 4th oil hose and first gear pump 13
Work under the drive of the 3rd spur gear 18, the lubricating oil entered in first gear pump 13 is passed through on first gear pump 13
Oil outlet C1 removal of lubricants, the lubricating oil that first gear pumps the oil outlet C1 discharges on 13 is delivered to cooler 20, through supercooling
But the cooling of device 20, is delivered to main oil gallery 9, the profit in main oil gallery 9 by lubricating oil after cooling by the 6th oil hose
Lubricating oil is passed sequentially through vertically in the first inner side oil duct of main oil gallery 9, the second inner side oil duct, the 3rd inner side oil duct, the 4th
Side oil duct, the 5th inner side oil duct, the 6th inner side oil duct and the 7th inner side oil duct are respectively the first inboard bearing 5-1-1, in second
Side bearing 5-2-1, the 3rd inboard bearing 5-3-1, the 4th inboard bearing 5-4-1, the 5th inboard bearing 5-5-1, the 6th inner shafts
Hold 5-6-1 and the 7th inboard bearing 5-7-1 is lubricated and cools down, lubricating oil is come back in arm body lubricating cavity 2, in order to follow
Ring utilizes；Meanwhile the lubricating oil of main oil gallery 9 penetrates through oil duct, described second by horizontal vertical among described in main oil gallery 9 first
Centre perforation oil duct, the perforation oil duct among the 3rd, perforation oil duct among the described 4th, perforation oil duct among the described 5th,
Perforation oil duct and the 7th perforation oil duct enter the first outside oil duct, the second outside oil duct, the 3rd outside among described 6th
Oil duct, the 4th outside oil duct, the 5th outside oil duct, the 6th outside oil duct and the 7th outside oil duct connection so that the profit of main oil gallery 9
Lubricating oil enters the first outboard bearing 5-1-2, the second outboard bearing 5-2-2, the 3rd outboard bearing 5-3-2, the 4th outboard bearing 5-
4-2, the 5th outboard bearing 5-5-2, the 6th outboard bearing 5-6-2 and the 7th outboard bearing 5-7-2, are the first outboard bearing 5-1-
2nd, the second outboard bearing 5-2-2, the 3rd outboard bearing 5-3-2, the 4th outboard bearing 5-4-2, the 5th outboard bearing 5-5-2,
Six outboard bearing 5-6-2 and the 7th outboard bearing 5-7-2 are lubricated and cool down, and lubricating oil is come back in arm body lubricating cavity 2,
Both easy to recycle, lubricating oil is reduced, lubricating oil can take away most of frictional heat of Bearing inner, meet the lubrication of bearing again
Cooling, while good heat dissipation effect, improve bearing service life, reduce failure rate, reduce production cost and maintenance cost, practical
Property is strong.
The above, is only presently preferred embodiments of the present invention, not the present invention is imposed any restrictions, it is every according to the present invention
Any simple modification, change and the equivalent structure change that technical spirit makees above example, still fall within skill of the present invention
In the compensation range of art scheme.
