When making, the lubricating oil after cooling is entered in the casing of bearing housing by fuel feed hole 21, and enters axle by the profit oil groove 51 on bearing 5
Hold and bearing 5 is lubricated and cooled down inside 5.The lubricating oil that profit oil groove 51 overflows flows into oil spilling room naturally through the second oil guide groove.
Lubricating oil in bearing 5 naturally also flows into oil spilling room after overflowing.The lubricating oil that the bearing 5 of rotation throws away or spilt at a high speed, is dredged
Bearing chamber interior wall and oil baffle ring 32 on oily collar bush 3 are stopped.A large amount of lubricating oil on bearing chamber interior wall are through oleophobic collar
Gap between the oil baffle ring 32 and bearing chamber interior wall of set 3 is flowed to outside bearing housing.By in oil baffle ring 32 and bearing housing
Gap between wall flows to elicitation effect of the lubricating oil first through the second oleophobic groove 33 outside bearing housing, is dredged to second and dredged

Lubricating oil is dredged to oil spilling room by the design of various cell bodies.
In addition it should be pointed out that, due to the high speed turning effort of bearing 5, compared to the lubricating oil on bearing chamber interior wall
For, the lubricating oil that oil baffle ring 32 is stopped will be far less than the lubricating oil on bearing chamber interior wall.In addition, in the present embodiment,
Oil pressure at fuel feed hole 21 is in high pressure conditions.But because oil spilling room by gap due to being in communication with the outside, oil spilling room is originally in
In atmospheric pressure state.And in fact, due to adding oleophobic collar bush 3 between line shaft and the axis hole of bearing housing, therefore, bearing housing
It also is difficult to sealing.Also therefore, pressure differential is mainly reflected between fuel feed hole 21 and oil spilling room.Pressure between oil spilling room and the external world
Poor very little.Also therefore, compared to oleophobic collar bush 3 and bearing chamber interior wall labyrinth, the first oleophobic groove on oleophobic collar bush 3
31 are enough dredged the lubricating oil flowed to through the gap between oleophobic collar bush 3 and line shaft outside bearing housing to first
In oleophobic groove 31.If oil spilling chamber pressure is larger, then the first oleophobic groove 31 is not enough to through between oleophobic collar bush 3 and line shaft
Gap flows to the lubricating oil outside bearing housing.
In addition, to cause the lubricating oil on oil baffle ring 32 to flow into faster in oil spilling room.The external annulus of oil baffle ring 32
