Embodiment

Figure 1 shows that an embodiment the schematic diagram of the oil pooling hood of the utility model gear drive.As shown in Figure 1, in the utility model one embodiment, oil pooling hood comprises oil pooling hood shell 1, disc 2 and return line 4.Oil pooling hood is set on the high speed level axle 3 of gear drive.

Fig. 2 is the side cross-sectional schematic of the gear drive with oil pooling hood shown in Fig. 1.As shown in Figure 2, oil pooling hood shell 1 is fixed on gear case body 10, and gear case body 10 has axis hole H, for a high speed level axle 3, passes.On level axle 3, be provided with bearing 20 at a high speed, in axis hole H, there is axle sleeve 30.Oil pooling hood shell 1 comprises pedestal 11 and housing 12, and pedestal 11 is fixed on gear case body 10, and has the first perforate H1 and pass for a level axle 3 at a high speed.Housing 12 is from pedestal 11 to stretching out away from the direction of gear case body 10.Housing 12 comprises diapire 121 and sidewall 122, and sidewall 122 extends along being parallel to the axial direction of level axle 3 at a high speed around level axle 3 at a high speed, and diapire 121 is perpendicular to level axle 3 at a high speed, and has the second perforate H2 for level axle 3 passes at a high speed.On sidewall 122, can also be provided with the partition wall 123 that is parallel to diapire 121, partition wall 123 is from the inside of sidewall 122 to growing near the direction of the axis of level axle 3 at a high speed, and keeps certain distance with the surface of level axle 3 at a high speed.

Disc 2 is set on high speed level axle 3.In one embodiment, disc 2 has belled part 21, annulus 22 and blade 23.Belled part 21 is tubular, and fixed cover is located at a high speed on level axle 3, and disc 2 can be rotated together along with a level axle 3 at a high speed.From belled part, the 21 radially outward portions along high speed level axle 3 grow annulus 22, and the number of annulus 22 is two in the present embodiment, and its axial direction along high speed level axle 3 is spaced apart and arranged on belled part 21.And the partition wall 123 of oil pooling hood shell 1 can be arranged between two annulus 22.In other embodiments, the number of annulus 22 can be one, or more than three, also can a plurality of partition walls 123 be set correspondence, by a plurality of annulus 22 separately.

On each annulus 22, there are a plurality of blades 23, between blade and blade, be preferably the identical distance in interval.Blade 23 extends away from the surface of gear case body 10 from annulus 22, and its bearing of trend is preferably the surface perpendicular to annulus 22, or has certain angle with the surface of annulus 22.Blade 23 can be prismatic blade or curved vane.Blade is the radial arrangement along annulus 22 in a preferred embodiment, and extends along the direction perpendicular to annulus 22 surfaces, and the central angle between two adjacent blades is 45 °.When disc 2 rotates along with high speed level axle 3, blade 23 can be converted into aerodynamic force by the higher rotating speed of high speed level axle 3, produces the effect of similar fan.In addition, disc 2 forms labyrinth seal structure with the partition wall 123 of oil pooling hood shell 1, makes oil pooling hood have dustproof function.

The housing 12 of oil pooling hood shell 1 is located on disc 2, and covers disc 2.The diameter of oil pooling hood shell 1 is greater than the diameter of disc 2, and the most significant end of the blade 23 of disc 2 still has certain distance apart from the sidewall 122 of oil pooling hood shell 1, so that air-flow can pass through.In addition, the diameter of the second perforate H2 on the diapire 121 of oil pooling hood shell 1 is greater than the diameter of the belled part 21 of disc 2, so that air-flow can pass through.The bottom of oil pooling hood shell 1 has return line 4, and return line 4 is communicated in the inside of oil pooling hood shell 1.

When level axle 3 rotates at a high speed, the lubricant oil of bearing 20 parts enters in oil pooling hood through the first perforate H1, by disc 2, get rid of and splash oil pooling hood shell 1, fluid flows to the bottom of oil pooling hood shell 1 along the sidewall 122 of oil pooling hood shell 1, then by return line 4, the poly-fluid of aggregation is discharged outside oil pooling hood.Simultaneously, a plurality of blades 23 of disc 2 are converted into aerodynamic force by the higher rotation speed of high speed level axle 3, the air-flow that produces gear drive internal heat is discharged to engine body exterior, as shown by the arrows in Figure 2, reach radiating effect, reduce gear housing inside temperature to affecting the working lifes such as bearing and gear, axle; Meanwhile, the air-flow discharging makes dust in gear-box Environmental Conditions to enter gear-box inside along the gap between oil pooling hood shell 1 and disc 2, will play good dustproof effect, reduces the adverse effect of dust to bearing and gear life.

In sum, the utility model adopts non-contact seal structure form, and the annulus 22 of disc 2 forms labyrinth seal structure with the partition wall of oil pooling hood shell 1 123, can play dustproof effect; Moreover, the blade 22 of disc 2 can be along with the effect that the rotation of level axle 3 produces similar fan at a high speed, deceleration body internal heat is discharged to engine body exterior, the air-flow discharging makes dust in gear-box Environmental Conditions to enter gear-box inside along gap between oil pooling hood and disc, has heat radiation and dust reduction capability.

Although described the utility model with reference to several exemplary embodiments, should be appreciated that term used is explanation and exemplary and nonrestrictive term.Because the utility model can specifically be implemented in a variety of forms and not depart from spirit of the present utility model or essence, so be to be understood that, above-described embodiment is not limited to any aforesaid details, and explain widely in the spirit and scope that should limit in claims, therefore fall into whole variations in claim or its equivalent scope and remodeling and all should be claims and contain.
