Detailed Description
With reference to fig. 1 to 3, in the leakage oil self-collecting device of the oil immersed type slip ring, an inner ring of a movable cover 4 of the oil immersed type slip ring is connected with a slip ring main shaft 1 through a first bearing 7, an inner end cover 5 is arranged above the connecting position, and the connecting position of the inner end cover 5 and the movable cover 4 is in a labyrinth structure; the outer ring of the movable cover 4 is connected with the outer cylinder 3 through a second bearing 8, an outer end cover 6 is arranged above the connecting position, and the connecting position of the outer end cover 6 and the outer cylinder 3 is in a labyrinth structure;
the labyrinth structure on the movable cover 4 is positioned at a high position relative to the labyrinth structure on the outer cylinder 3, the labyrinth structure on the movable cover 4 is used as an oil collecting groove of an inner ring, the labyrinth structure on the outer cylinder 3 is used as an outer ring oil collecting groove, an oil guide pipe 16 is arranged between the inner ring oil collecting groove and the outer ring oil collecting groove to realize oil path connection, accumulated oil of the inner ring oil collecting groove spontaneously flows to the outer ring labyrinth groove through the oil guide pipe 16 and a valve block 17 under the action of gravity, and waste oil is completely collected to a waste oil collecting tank 19 through an oil discharge pipe 18 connected with the bottom of the outer ring oil collecting groove. The valve block 17 is used for switching, and the connection between the oil pipe 16 and the outer end cover 6 is realized.
As a specific example, a first static seal 9 is disposed between the first bearing 7 and the slip ring main shaft 1, a second static seal 11 is disposed between the first bearing 7 and the moving cover 4, and a first moving seal 10 is disposed between a stationary portion and a rotating portion in the first bearing 7.
As a specific example, a third static seal 12 is disposed between the second bearing 8 and the movable cover 4, a fifth static seal 15 is disposed between the second bearing 8 and the outer cylinder 3, a fourth static seal 13 is disposed between the movable cover 4 and the outer cover 6, and a second dynamic seal 14 is disposed between the stationary part and the rotating part of the second bearing 8.
With reference to fig. 3, the movable cover 4 is connected to the support frame 2 through a second bearing 8.
The leakage oil liquid self-collecting device of the oil immersed slip ring has the following leakage oil liquid collecting principle:
when the movable cover 4 rotates, the oil in the slip ring can be oozed out by the first movable sealing member 10 and the second movable sealing member 14 in a small amount. Due to the presence of the first static seal 9 and the second static seal 11, oil exuded from the first dynamic seal 10 will flow into the labyrinth grooves on the dynamic cover 4. Due to the presence of the third static seal 12, the fourth static seal 13 and the fifth static seal 15, oil seeping from the second dynamic seal 14 will flow into the labyrinth grooves on the outer cylinder 3.
An oil guide pipe 16 is connected between the two labyrinth grooves. Because the inner ring labyrinth groove is at a high position, accumulated oil in the inner ring labyrinth groove spontaneously flows to the outer ring labyrinth groove through the oil guide pipe 16 and the valve block 17 under the action of gravity. An oil drain pipe 18 is connected to the lower part of the outer ring labyrinth groove. The accumulated oil in the outer ring labyrinth groove flows into the waste oil collecting tank 19 through the oil discharge pipe 18. Thereby realizing the collection of oil leakage.
In summary, the invention can collect waste oil only by arranging the collecting tank on the outer wall of the slip ring, and has the advantages of simple and reliable structure and low cost.
