The utility model discloses an aerogenerator shaft seal device adopts the structure of two kinds of sealing method combinations, under the dual function of labyrinth seals structure and sealing member, has solved the problem that the main shaft bearing grease leaked effectively, has guaranteed main shaft bearing's safe operation, has reduced the maintenance cost, has improved product quality.
Description
Technical field
The utility model relates to wind-power electricity generation machinery field, particularly relates to a kind of wind driven generator principal shaft seal arrangement.
Background technique
What current wind driven generator principal shaft sealing generally adopted is oil sealing, v-seal, felt seal etc., but actual effect is all undesirable.Because fan operation environment is poor, in time long, bearing, grease-filled amount is large, and seal clearance can produce certain change, therefore uses single sealing means easily to cause grease to leak.Grease leakage can affect main shaft bearing security of operation, affects the working environment in cabin, even also can produce certain potential safety hazard to blower fan.
In sum, how the wind driven generator principal shaft seal arrangement that a kind of structure is simple, processing and assembling convenient, sealing effect is better, effectively can eliminate grease leakage problem is provided, has become those skilled in the art's problem demanding prompt solution.
Model utility content
In view of this, the utility model proposes a kind of wind driven generator principal shaft seal arrangement, to solve the technical problem that existing single sealing means easily causes grease to leak.
On the one hand, the utility model provides a kind of wind driven generator principal shaft seal arrangement, comprise the axle sleeve be fixed on main shaft and the end cap be fixed on bearing support, between described end cap and described axle sleeve, form a labyrinth seal structure, leak for reducing grease in the inside of seal arrangement; Sealing is provided with, for preventing grease from leaking in the outside of seal arrangement between the outer surface of described axle sleeve and described end cap.
As the improvement on the one hand of a kind of wind driven generator principal shaft seal arrangement of the utility model, described labyrinth seal structure comprises the first labyrinth groove and the second labyrinth groove, described first labyrinth groove is arranged on described axle sleeve, described second labyrinth groove is arranged on described end cap, described first labyrinth groove and the second labyrinth groove cooperatively interact, and the space between described first labyrinth groove and the second labyrinth groove forms labyrinth sealing.
As the improvement on the one hand of a kind of wind driven generator principal shaft seal arrangement of the utility model, described second labyrinth groove is stepped recesses, and described Sealing is arranged in described stepped recesses.
As the improvement on the one hand of a kind of wind driven generator principal shaft seal arrangement of the utility model, described Sealing is oil sealing, V-shaped seal ring or felt seal ring.
As the improvement on the one hand of a kind of wind driven generator principal shaft seal arrangement of the utility model, also comprise sealing baffle, described sealing baffle is arranged at the outside of described Sealing, for Sealing is fixed on end cap.
The wind driven generator principal shaft seal arrangement that the utility model provides, comprise the axle sleeve be fixed on main shaft and the end cap be fixed on bearing support, form a labyrinth seal structure between described end cap and described axle sleeve, leak for reducing grease in the inside of seal arrangement; Sealing is provided with, for preventing grease from leaking in the outside of seal arrangement between the outer surface of described axle sleeve and described end cap.Compared to existing technologies, wind driven generator principal shaft seal arrangement of the present utility model adopts the structure of two kinds of sealing means combinations, labyrinth seal structure is adopted in seal arrangement inside, inner length and gap is little and grease leakage rate effectively can be reduced in the labyrinth of complications, the energy that when reducing bearing element, grease is arranged outward; In the outside of seal arrangement, Sealing can intercept again to the grease leaked out on a small quantity, thoroughly prevents grease from leaking, and the impurity such as outside dust can be stoped simultaneously to enter in labyrinth and bearing, avoid the damage of labyrinth and bearing.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:

Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, a kind of wind driven generator principal shaft seal arrangement, comprise axle sleeve 4 and end cap 3, axle sleeve 4 is fixed on main shaft 5, end cap 3 is fixed in bearing support (not shown), form a labyrinth seal structure between end cap 3 and axle sleeve 4, leak for reducing grease in the inside of seal arrangement; Meanwhile, between the outer surface of axle sleeve 4 and end cap 3, be also provided with Sealing 2, for preventing grease from leaking in the outside of seal arrangement.By above-mentioned setting, under the double action of labyrinth seal structure and Sealing 2, efficiently solve the problem that main shaft bearing grease leaks, ensure that the safe operation of main shaft bearing.
Particularly, aforementioned labyrinth seal structure comprises the first labyrinth groove and the second labyrinth groove, first labyrinth groove is arranged on axle sleeve 4, second labyrinth groove is arranged on end cap 3, first labyrinth groove and the second labyrinth groove cooperatively interact, and namely the space between the first labyrinth groove and the second labyrinth groove forms labyrinth sealing.It should be noted that, this labyrinth seal structure is arranged at the close main shaft bearing end of axle sleeve 4 and end cap 3.
Meanwhile, as shown in Figure 1, the second labyrinth groove on end cap 3 is stepped recesses, and Sealing 2 is specifically installed in the left end groove of this stepped recesses.It should be noted that, the seal 2 is preferably oil sealing.But it is worth mentioning, other Sealings of sealing function can be realized if V-shaped seal ring, felt seal ring etc. are all within protection domain of the present utility model.
Further, aforementioned wind driven generator principal shaft seal arrangement also comprises sealing baffle 1, and sealing baffle 1 is arranged at the outside of Sealing 2, for Sealing 2 is fixed on end cap 3.
In sum, wind driven generator principal shaft seal arrangement of the present utility model have employed the dual sealing manner of labyrinth seal and Sealing 2 sealing, fixed axle sleeve 4 on main shaft 5, leaning on main shaft bearing end and the end cap 3 be fixed on bearing support of axle sleeve 4 forms a labyrinth seal structure, and end cap 3 is provided with a stepped recesses, Sealing 2 is arranged in the stepped recesses of end cap 3, is formed seal with the outer surface of axle sleeve 4.In addition, the outside of Sealing 2 is also provided with a sealing baffle 1, for Sealing 2 is fixed on end cap 3.By above-mentioned setting, the length of labyrinth seal structure inside and gap is little and grease leakage rate effectively can be reduced in the labyrinth of complications, the energy that when reducing bearing element, grease is arranged outward; In the outside of seal arrangement, Sealing 2 can intercept again to the grease leaked out on a small quantity, thoroughly prevent grease from leaking, the impurity such as outside dust can be stoped to enter in labyrinth and bearing simultaneously, avoid the damage of labyrinth and bearing, replacing and the maintenance cost of great number can not be produced, improve quality of product.
