Description

Annular double-labyrinth multi-lip spring energy storage sealing device for wind power main bearing
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 that external dust, water, salt fog from getting into the two maze multiple lip spring energy storage sealing device of wind-powered electricity generation main bearing annular of bearing inner chamber.
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, two maze multi-lip spring energy storage sealing device of wind-powered electricity generation base bearing annular, it can realize that wind-powered electricity generation base bearing raceway chamber obtains effective seal, 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:
An annular double-labyrinth multi-lip spring energy storage sealing device for an electric main bearing comprises a sealing ring and a spring energy storage rubber base body, wherein the spring energy storage rubber base body is of an annular structure and is fixedly arranged on an inner ring of the main bearing; the hole of sealing washer and the excircle glue of spring energy storage rubber base member unite, be equipped with contact lip and a plurality of oblique angle maze lip on the excircle of sealing washer, the contact lip is used for contacting with the inner wall of main bearing outer lane, oblique angle maze lip be used for with the main bearing inner lane on the seal groove cooperation form labyrinth structure.
In the annular double-labyrinth multi-lip spring energy storage sealing device for the electric main bearing, two oblique angle labyrinth lips are arranged on the outer circle of the sealing ring, and the contact lip is positioned between the two oblique angle labyrinth lips.
In the annular double-labyrinth multi-lip spring energy storage sealing device for the electric main bearing, the bevel labyrinth lip is 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 utility model discloses a spring energy storage rubber base member installs and circles in the base bearing, and the oblique angle labyrinth lip of sealing washer gos deep into the labyrinth structure that the sealing groove on the base bearing outer lane inner wall formed, contact lip and the contact of base bearing outer lane inner wall. 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. The labyrinth structure on the right further prevents the fluid grease of a closed surface formed by the contact of the contact lip and the inner diameter of the outer ring of the rotating main bearing and prevents external dust, water and salt mist 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.
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.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is the working installation diagram of the present invention.
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 base member 4, spring energy storage rubber base member 4 be the loop configuration for fixed mounting circles in the base bearing. The hole of sealing washer and the excircle glue of spring energy storage rubber base member 4 unite, be equipped with contact lip 2 and oblique angle labyrinth lip 1 and oblique angle labyrinth lip 3 on the excircle of sealing washer, contact lip 2 be used for with the inner wall contact of base bearing outer lane, oblique angle labyrinth lip 1 and oblique angle labyrinth lip 3 be used for with the bearing inner lane on the seal groove cooperation form labyrinth structure. The contact lip is positioned between the two bevel labyrinth lips. Bevel labyrinth lips 1 and 3 are made of Hydrogenated Nitrile Butadiene Rubber (HNBR).
The working principle of the utility model is as follows:
The utility model discloses during the use, the utility model discloses a spring energy storage rubber base member installs and circles in the base bearing, and the oblique angle labyrinth lip of sealing washer gos deep into the labyrinth structure that the sealing groove on the base bearing outer lane inner wall formed, contact lip and the contact of base bearing outer lane inner wall. 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. The labyrinth structure on the right further prevents the fluid grease of a closed surface formed by the contact of the contact lip and the inner diameter of the outer ring of the rotating main bearing and prevents external dust, water and salt mist 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.
