, the current limliting head 16 for being placed on 15 top of oil transportation hole and the steel wire 17 for being threaded through oil transportation channel 7 can reduce the stream of lubricating oil
Amount, ooze out lubricating oil slowly from oil outlet, so, can both reduce the oil transportation channel 7 of central axis 2 processing request and
Difficulty of processing, and lubricating oil can be caused rapidly losing to avoid oil transportation channel 7 is excessive.
Further, 1 bottom of shell is arranged around the slope 18 of rolling bearing 4, the outer edge on the slope 18 with
6 edge of gear wheel above it is corresponding and extends to the upper surface of corresponding rolling bearing 4 obliquely；2 bottom end of central axis
It is also equipped with oil storage disc 14,14 upper surface of the oil storage disc setting tool internal thread groove, 2 bottom end of central axis is arranged outer
Screw thread is simultaneously threadedly coupled with 14 upper surface of oil storage disc；The groove location of 14 upper and lower surface of oil storage disc is corresponding, the central axis 2
The pit for accommodating current limliting head 16 is arranged in bottom end.It should be understood that will be slow after Lubricant on Gear 3 is lubricated
Assemble and drip on slope 18, and flow to rolling bearing 4 along slope 18, eventually passes through rolling bearing 4 along central axis 2 and flow to center
The oil storage disc 14 of 2 bottom end of axis.The oil storage disc 14 of 2 bottom end of central axis can be collected the lubricating oil for carrying out lubrication, in the middle
After lubrication oil consumption in the oil storage disc 14 on 2 top of mandrel is complete, the oil storage disc 14 of 2 top of central axis and bottom end can be exchanged position
It sets, to make lubricating oil is available to recycle.
Further, a ring is arranged around the fin 19 of groove in the upper surface of the oil storage disc 14, and the fin 19 is cut
Face is triangular in shape, and the one side of the fin 19 towards groove is bonded with 2 circumferential surface of central axis, another side extends to oil storage disc obliquely
14 upper surfaces.It should be understood that intermeshing gear wheel 6 can be inevitably because of phase in transmission process with pinion gear 5
Mutual friction and generate small scrap, and with lubricating oil flow into 2 bottom end of central axis oil storage disc 14 in, with 2 weeks face pastes of central axis
Scrap can be oriented between fin 19 and 14 circumferential surface of oil storage disc by the fin 19 of conjunction, when the displacement of oil storage disc 14 of 2 bottom end of central axis is arrived
When 2 top of central axis, fin 19 can play the role of stop scrap, so that it is trapped in the bottom of oil storage disc 14, avoid scrap into
Enter in oil transportation channel 7, oil transportation channel 7 is caused to block.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that not
Under the premise of the principle and substance of the present invention, many changes and modifications may be made, but these become
More protection scope of the present invention is each fallen with modification.
