Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only of the invention
A part of the embodiment, instead of all the embodiments.Based on the embodiment of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
Below in conjunction with attached drawing, the technical solution of embodiment that the present invention will be described in detail offer.
The embodiment of the invention provides a kind of gear train self-lubricating devices, and as shown in attached drawing 1 to 5, which includes: gear
Axis 1, gear 2, first shell 3, second shell 4, swash plate 5, plunger 6 and oil distribution casing 7.Gear 2 is rotatably mounted around gear shaft 1
On, first shell 3 and second shell 4 are separately positioned on the two sides of gear 2.Swash plate 5 is arranged on the inner wall of first shell 3, and
The circumferentially gradual change of the thickness of swash plate 5.It is provided on gear 2 along axial plunger hole 8, plunger 6 is located in plunger hole 8 and passes through bullet
Property part 9 support, in 2 rotation process of gear, top and the swash plate 5 of plunger 6 offset.The inner wall of second shell 4 is arranged in oil distribution casing 7
On, and be connected to the bottom end of plunger hole 8, it is discharged for the oil inlet into plunger hole 8 or by the lubricating oil in plunger hole 8.
The working principle of gear train self-lubricating device provided in an embodiment of the present invention is illustrated below:
The top of plunger 6 is contacted with swash plate 5, and in 2 rotation process of gear, plunger 6 is rotated with gear 2,6 tip contact of plunger
The thickness of swash plate 5 gradually change.When plunger 6 rotates, top turns to the mistake of the most thin position of swash plate 5 from the most thick position of swash plate 5
Cheng Zhong, plunger 6 gradually move up, and the lubricating oil in oil distribution casing 7 enters plunger from the bottom end of plunger hole 8 under action of hydraulic force
In hole 8.When 6 top of plunger is turned to during the most thick position of swash plate 5 from the most thin position of swash plate 5, plunger is gradually 6 to moving down
Dynamic, the lubricating oil in plunger hole 8 enters in oil distribution casing 7 to be discharged by oil distribution casing 7, flows to region to be lubricated.
As it can be seen that gear train self-lubricating device provided in an embodiment of the present invention, passes through setting thickness different swash plate 5 and plunger
6 top offsets, and plunger 6 is moved with moving up and down under common driving of the swash plate 5 with elastic component 9 in 2 rotation process of gear
The extraction and discharge of oil are lubricated during dynamic, with gear 2 rotate lubricating oil transfer to from the side of oil distribution casing 7 it is another
Side reaches lubrication purpose.It transfers power to be provided by the pressure difference that the rotation of gear 2 generates, gear train is completed from driving by gear 2
Self-lubricating is not necessarily to additional pump-in pressure, and structure is simple, reduces equipment volume, and the scope of application is wider.
Wherein, the quantity of plunger hole 8 and plunger 6 can be one or more, and the quantity of plunger 6 is more, and gear 2 is each
The lubricating oil transported in rotation process is more, and plunger appropriate can be arranged according to field working conditions and lubrication needs etc. in staff
8 quantity of hole, to reach good lubricant effect.
It for the structure of oil distribution casing 7, is illustrated below: as shown in Fig. 2, being provided with oil-feed tank on oil distribution casing 7
71 and oil groove 72 out, oil inlet 7a is provided on oil-feed tank 71, and oil inlet 7a is opposite with the swash plate the smallest position of 5 thickness, fuel-displaced
Oil outlet 7b is provided on slot 72, oil outlet 7b is opposite with the swash plate maximum position of 5 thickness, in 2 rotation process of gear, plunger hole
With oil-feed tank 71 or out, oil groove 72 is connected to for 8 bottom end.
So set, plunger 6 is in 2 rotation process of gear, when plunger 6 rotates, top is turned to from the most thick position of swash plate 5
During the most thin position of swash plate 5, plunger 6 is gradually moved up, and the bottom end of plunger hole 8 is gradually pumped by oil-feed tank 71.6 turns of plunger
When dynamic, during top turns to the most thick position of swash plate 5 from the most thin position of swash plate 5, plunger 6 is gradually moved down, the bottom of plunger hole 8
End is by going out the gradually oil extraction of oil groove 72.Oil inlet 7a is connected to oil-feed tank 71, fuel-displaced convenient for conveying lubricating oil into oil-feed tank 71
