Embodiment 1
[0037] figure 2 It is a structural diagram of a lubricating oil filling system disclosed in the embodiment of this application.
[0038] Such as figure 2 As shown, the lubricating oil filling system of this embodiment includes an oil tank 30, an oil pump 40, a first pipeline L1 and a second pipeline L2.
[0039] The oil pump 40 is provided with an oil inlet 41 and an oil outlet 42 .
[0040] The oil tank 30 is used to store lubricating oil, and the oil tank 30 communicates with the oil inlet 41 of the oil pump 40 through the first pipeline L1.
[0041] The oil outlet 42 of the oil pump 40 communicates with the oil hole 21 of the gearbox 20 through the second pipeline L2. Before the gearbox 20 is tested, the oil pump 40 delivers the lubricating oil stored in the oil tank 30 to the gearbox 20 .
[0042] As can be seen from the above scheme, the lubricating oil filling system disclosed in the embodiment of the present application includes an oil tank 30 and an oil pump 40. ...
Embodiment 2
[0045] image 3 A lubricating oil filling system disclosed in another embodiment of the present application.
[0046] Such as image 3 As shown, the lubricating oil filling system of this embodiment adds a metering oil tank 50, an on-off valve T, a heating device 31, and a stirring device 32 on the basis of the first embodiment, wherein: the metering oil tank 50 and the on-off valve T are both arranged at the second On a pipeline L1, the switch valve T is located between the metering oil tank 50 and the oil tank 30, and the heating device 31 and the stirring device 32 are both arranged in the oil tank.
[0047] The metering oil tank 50 is used for metering the delivered lubricating oil, and the absolute height of the metering oil tank 50 is lower than the oil tank 30 , so that the lubricating oil in the oil tank 30 can flow into the metering oil tank 50 by itself. When the gearbox 20 needs to be filled with lubricating oil, open the on-off valve T arranged on the first pipel...
