Description
Technical Field
The utility model relates to a prevent that fluid form lubricating grease from leaking from the sealed bearing inner chamber by sealing device, also prevent the wind-powered electricity generation main bearing annular list maze lip spring energy storage sealing device of the bearing inner chamber that external dust, water, salt fog got into.
Background
At present, wind-powered electricity generation base bearing is in actual operation, and long-time sealing function can't be guaranteed to sealing device's sealing performance between the outer lasso in the base bearing, appears leaking the fat phenomenon. The maintenance cost of the fan is increased, the working environment is deteriorated, and the environment cleaning workload is increased. 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.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a simple structure, single maze many lips spring energy storage sealing device of wind-powered electricity generation base bearing annular with low costs, it can realize that wind-powered electricity generation base bearing raceway chamber obtains effectively sealed, reduces the maintenance cost of fan, improves operational environment, reduces environment clearance work load, improves the raceway intracavity pressure of base bearing and the lubricated effect of lubricating grease to the bearing.
The utility model adopts the technical proposal that:
The annular single-labyrinth multi-lip spring energy storage sealing device for the wind power main bearing comprises a sealing ring and a spring energy storage rubber base body, wherein the spring energy storage rubber base body is annular and is used for being arranged on an inner ring of the main bearing; the sealing ring is connected on the spring energy storage rubber base body in an adhesive mode to form a whole, an oblique angle labyrinth lip and a contact lip are arranged on the outer circle of the sealing ring, the oblique angle labyrinth lip is used for forming labyrinth seal with a sealing groove in the inner wall of the outer ring of the main bearing, and the contact lip is used for being in contact with the inner wall of the outer ring of the main bearing.
In the annular single-labyrinth multi-lip spring energy storage sealing device for the wind power main bearing, the contact lip comprises a middle contact lip and an oblique angle contact lip, the middle contact lip and the oblique angle contact lip are located on the same side of the oblique angle labyrinth lip, and the middle contact lip is located between the oblique angle contact lip and the oblique angle labyrinth lip.
In the annular single-labyrinth multi-lip spring energy storage sealing device for the wind power main bearing, the bevel contact lip and the bevel labyrinth lip are made of hydrogenated nitrile rubber.
Compared with the prior art, the beneficial effects of the utility model are that:
The utility model discloses during the use, the fluid form lubricating grease of main bearing intracavity flows the labyrinth structure who forms via the sealed slot on the oblique angle labyrinth lip deepens the main bearing outer lane inner wall, reduces the pressure and the throughput of fluid form lubricating grease, has reduced the pressure of the fluid form lubricating grease of the closed face that middle contact lip and main bearing outer lane inner wall contact formed, makes the closed face that middle contact lip and main bearing outer lane inner wall contact formed, can prevent the closed face that the contact of the middle contact lip and main bearing outer lane inner wall formed of fluid form lubricating grease. The bevel contact lip contacts with the inner wall of the outer ring of the main bearing to form a single closed surface, and further prevents fluid-shaped lubricating grease of the closed surface formed by the contact of the middle contact lip and the inner wall of the outer ring of the main bearing and prevents external dust, water and salt mist from entering the inner cavity of the bearing, so that a channel for blocking the external space and the inner part of the main bearing in a rotating state is formed.
The utility model discloses simple structure, it is with low costs, and can realize the good sealed between the inside and outside lasso of base bearing, guarantee long-time sealing performance in the messenger's base bearing between the inside and outside lasso, reduce and leak the fat phenomenon. The maintenance cost of the fan is reduced, the working environment is improved, the environment cleaning workload is reduced, and the pressure in the raceway cavity of the main bearing and the lubricating effect of lubricating grease on the bearing can be improved.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in figure 1, the utility model discloses a sealing washer and spring energy storage rubber substrate 4, spring energy storage rubber substrate 4 be the annular for install on the base bearing inner race. The sealing washer is glued and is linked to become an organic whole on spring energy storage rubber substrate 4, is equipped with bevel angle labyrinth lip 1, middle contact lip 2 and bevel angle contact lip 3 on the excircle of sealing washer 4, and bevel angle labyrinth lip 1 is used for forming labyrinth seal with the sealing groove on the main bearing outer lane inner wall, and middle contact lip 2 and bevel angle contact lip 3 are used for contacting with the inner wall of main bearing outer lane. The middle contact lip 2 and the bevel contact lip 3 are located on the same side of the bevel labyrinth lip 1, and the middle contact lip 2 is located between the bevel contact lip 3 and the bevel labyrinth lip 1. The bevel contact lip 3 and the bevel labyrinth lip 1 are made of Hydrogenated Nitrile Butadiene Rubber (HNBR).
As shown in fig. 2, during the use of the utility model, the utility model discloses a sealing device installs the interior epaxial sealing device mounting groove 5 of circle of base bearing by installation component 6 after, bevel angle labyrinth lip 1 deepens the seal groove formation labyrinth seal structure on the base bearing outer lane inner wall, and the fluid form lubricating grease of main bearing intracavity flows through and reduces the pressure and the throughput of fluid form lubricating grease by labyrinth seal structure, reduces the pressure of the fluid form lubricating grease of the closed surface of contact lip 2 and the contact formation of base bearing outer lane inner wall in the middle of the reduction. The closed surface formed by the intermediate contact lip 2 contacting the inner wall of the outer ring of the main bearing can prevent the fluid grease from contacting the inner wall of the outer ring of the main bearing through the intermediate contact lip 2. The bevel contact lip is contacted with the inner wall of the outer ring of the main bearing to form a single closed surface, so that the fluid lubricating grease passing through the closed surface formed by the contact of the middle contact lip 2 and the inner wall of the outer ring of the main bearing is further prevented, and external dust, water and salt mist are prevented from entering the inner cavity of the bearing. Thereby serving to block the passage between the external space and the inside of the main bearing in a rotating state.
