Description
Technical Field
The utility model belongs to wind-powered electricity generation base bearing sealing device field especially relates to a many labyrinths multi-lip spring energy storage sealing device of compound parallel continuous arrangement of wind-powered electricity generation base bearing annular.
Background
At present, in wind-powered electricity generation base bearing actual operation, sealing device's between the interior, outer lasso circle sealing performance can't guarantee long-time sealed function, appears leaking the fat phenomenon. This kind of hourglass fat phenomenon has increased the maintenance cost of fan, worsens operational environment, increases environmental cleaning work load. Therefore, the more effective sealing device of the main bearing can not only realize the reduction of the maintenance cost of the fan, the improvement of the working environment and the reduction of the environment cleaning workload, but also improve the pressure in the raceway cavity of the main bearing and the lubricating effect of lubricating grease on the bearing.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a many labyrinths multi-lip spring energy storage sealing device of compound parallel continuous arrangement of wind-powered electricity generation base bearing annular. The leakage of the fluid lubricating grease from the bearing inner cavity sealed by the sealing device is prevented, and external dust, water and salt mist are prevented from entering the bearing inner cavity; the main bearing raceway cavity of the wind power generation device is simple in structure and low in cost, the main bearing raceway cavity of the wind power generation device can be effectively sealed, the maintenance cost of a fan is reduced, the working environment is improved, the environment cleaning workload is reduced, and the lubricating effect of the pressure in the raceway cavity of the main bearing and lubricating grease on the bearing is improved.
The utility model adopts the technical proposal that:
a wind power bearing is with arranging many labyrinths multi-lip spring energy storage sealing device continuously, including seal ring and spring energy storage rubber substrate 4; the spring energy storage rubber base body 4 is of an annular structure and is fixedly arranged on an inner ring of the wind power main bearing; the inner circle of the sealing ring is glued with the outer side of the spring energy storage rubber base body 4, and the outer circle of the sealing ring is provided with a contact lip 3 and a plurality of bevel labyrinth lips; the contact lip 3 is used for contacting with the inner wall of the outer ring of the wind power main bearing, and the bevel angle labyrinth lip is used for forming a labyrinth structure by matching with a sealing groove on the inner wall of the outer ring of the main bearing.
Two bevel labyrinth lips which are continuously arranged in parallel are arranged on the excircle of the sealing ring and are respectively a bevel labyrinth lip a1 and a bevel labyrinth lip b2; the contact lip 3 is located in front of the two bevel labyrinth lips.
An energy storage spring is arranged in the spring energy storage rubber base body 4, and after the device is installed, the energy storage spring is in an energy storage state.
The bevel labyrinth lip material is hydrogenated nitrile rubber.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses simple structure, it is with low costs, and can realize the good sealing between the interior, outer lasso of base bearing, guarantee long-time sealing performance in making the base bearing between the interior, outer lasso, reduce and leak the fat phenomenon, and can reduce the maintenance cost of fan, improve operational environment, reduce environment clearance work load, but also can improve the raceway intracavity pressure of base bearing and the lubricated effect of lubricating grease to the bearing. The fluid-shaped lubricating grease in the main bearing cavity flows through the left labyrinth structure, so that the pressure and the throughput of the fluid-shaped lubricating grease are reduced, the pressure of the fluid-shaped lubricating grease on a closed surface formed by the contact lip in contact with the inner diameter of the outer ring of the main bearing is reduced, the closed surface formed by the contact lip in contact with the inner diameter of the outer ring of the main bearing can be prevented, and the closed surface formed by the contact lip in contact with the inner wall of the outer ring of the main bearing can be prevented.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is the working installation diagram of the present invention.
In the figure: 1-bevel angle labyrinth lip a, 2-bevel angle labyrinth lip b, 3-contact lip and 4-spring energy storage rubber matrix.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and technical solutions.
As shown in figure 1, the utility model discloses a bevel angle maze lip a1, bevel angle maze lip b2, contact lip 3, sealing washer and spring energy storage rubber base member 4. The spring energy storage rubber base body 4 is of an annular structure and is fixedly arranged on an inner ring of the wind power main bearing. The interior circle of sealing washer and the excircle of spring energy storage rubber base member 4 glue and unite as an organic whole, be equipped with contact lip 3 and continuous parallel arrangement oblique angle labyrinth lip a1 and oblique angle labyrinth lip b2 on the excircle of sealing washer, contact lip 3 be used for with the inner wall contact of wind-powered electricity generation base bearing outer lane, oblique angle labyrinth lip a1 and oblique angle labyrinth lip b2 be used for with the bearing inner lane on the seal groove cooperation form labyrinth structure.
