Specific embodiment
Elaborate below to the embodiment of the utility model, the present embodiment using technical solutions of the utility model before
It puts and is implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited
In following embodiments.
As shown in Figs 1-4, a kind of blower fan axle head sealing device, including draught fan impeller 7, axis 1, bearing block 5, Water-cooling seat 6, end
Lid 3, the draught fan impeller 7 are fixed on axis 1, and the axis 1 is supported on by former and later two bearings 5 on Water-cooling seat 6, the Water-cooling seat
6 both ends of the surface are respectively provided with the space that an end cap 3 forms sealing.Being equipped between the bearing 5 and end cap 3 prevents oil leak
Disc 2, described to get rid of oily 2 ring sets and be set on axis 1, the disc 2 is annular solid, and the outer surface of the disc 2 is cone
Face structure, accumulating in the lubricating oil of front in this way can be thrown on the medial surface of end cap 3 under the high-speed rotation of axis 1 by disc,
Then it flows back into inside Water-cooling seat 6 again.Preferably, the upper surface length of the cone structure is 33.8mm, lower surface length
For 39mm.2 inner surface of disc is equipped with strip slot 21, preferably, 2 upper surface of the disc and strip slot
21 upper walls parallel, the strip slot 21 are extended with bulge loop 22,2 lower surface of disc towards 2 inner surface side of disc
Ladder-type trough 24 is equipped between inner surface, the internal diameter of the disc 2 is 75mm.
Specifically, the arc groove 23 that 2 upper surface of disc is equipped with, fastening is equipped on the arc groove 23
Retainer 4, what fastening retainer 4 can be tightly is wrapped on axial plane, and such lubricating oil cannot be along axial plane with regard to can only accumulate in front
Exudation, the path that lubricating oil is effectively prevented to be oozed out along axial plane.Preferably, 23 radius of arc groove is 1.5mm, institute
State elastic fastening retainer 4 of the fastening retainer 4 using open type.
The disc 2 uses elastic material, preferably, the disc 2 is made of nitrile rubber vulcanization, this reality
2 gel content of disc in example is more than 50%, shore hardness 70.
In this example, the inside of the end cap 3 is maze-type structure, and the inside of the end cap 3 is provided with oil-recovery tank.
During using installation, fan shaft 1 is stalled first, the axial plane for locking 2 installation site of oil ring is cleaned up, it is impossible to there are
Sundries and greasy dirt；Confirm the gap between bearing 5 and end cap 3, then both hands are held disc 2 and are broken into two with one's hands outward, circular conical surface it is big
Disc 2 is sleeved on axis 1 when the aperture that is open is slightly larger than 1 diameter of fan shaft, disc 2 is because of elasticity towards inboard by nose circle
Meeting automatic tightening, is fitted on axial plane；Then both hands hold expanding fastening retainer 4 be open both ends, respectively forwardly latter two
Direction is broken into two with one's hands retainer 4 is fastened, until mismatch size stops force when being more than cushion rubber outer diameter, fastening retainer 4 is placed on disc 1
At the arc groove 23 of outer circle because spring lock ring 4 can automatic tightening, banding cushion rubber further increase 2 inner headed face of disc with
End cap 3 is finally mounted on by original position on Water-cooling seat 6 by the fitting of axial plane.
The utility model increases a disc 2 in end cap 3 and 6 end face of Water-cooling seat and the space of axis 1, this gets rid of oily 2 rings
It is opening and matches the elastic fastening retainer 4 there are one open type with certain elasticity, on disc 2, therefore can be tightly
It is wrapped on axial plane, such lubricating oil just can only accumulate in front and cannot be oozed out along axial plane, effectively prevent lubrication
The path that oil is oozed out along axial plane.In addition, the periphery of disc 2 is cone structure, height of the lubricating oil in axis 1 of front is accumulated in
Speed rotation is lower to be thrown to by disc 2 on the medial surface of end cap 3, then flowed back into inside Water-cooling seat 6 again, so as to effectively solve
The problem of axis 1 end oil seepage.
The present apparatus is Demountable, is easily installed and replaces, easy to operate, does not influence the fortune at other positions of wind turbine
Row, is highly suitable for the quick upgrading to wind turbine online, the utility model can fundamentally prevent wind turbine oil leak
Problem.And the present apparatus is simple in structure, at low cost, and suitable for production, application is strong.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
