Description
Technical Field
The utility model relates to a prevent that fluid form lubricating grease from leaking from the sealed main bearing inner chamber by sealing device, also prevent that external dust, water, salt fog from getting into the rubber seal device of the two labyrinth multi-lip linear spring locking of electricity main bearing annular of main 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, the rubber seal device of two maze multi-lip linear spring locking of wind-powered electricity generation base bearing annular of low cost, 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 cleaning 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:
A rubber sealing device locked by an annular double-labyrinth multi-lip linear spring of a wind power main bearing comprises a base body, a sealing ring and a linear locking spring; the base body is of an annular structure and is used for being arranged on an outer ring of the main bearing; the outer circle of the sealing ring is glued with the inner hole of the base body, an annular spring mounting groove is formed in the outer circle of the sealing ring, and the linear locking spring is arranged in the spring mounting groove and hoops the sealing ring tightly; the inner wall of the sealing ring is provided with a contact lip and a plurality of bevel labyrinth lips, the contact lip is used for contacting with the excircle of the inner ring of the main bearing, and the bevel labyrinth lips are used for being embedded into a sealing groove on the inner ring of the main bearing to form a labyrinth structure.
In the rubber sealing device locked by the annular double-labyrinth multi-lip linear spring of the wind power main bearing, the inner wall of the sealing ring is provided with two oblique angle labyrinth lips, and the contact lip is positioned between the two oblique angle labyrinth lips.
In the rubber sealing device locked by the annular double-labyrinth multi-lip linear spring of the wind power main bearing, the bevel labyrinth lip is made of hydrogenated nitrile rubber.
In the rubber sealing device locked by the annular double-labyrinth multi-lip linear spring of the wind power main bearing, the base body is made of cloth-sandwiched 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 base member is installed on the outer lane of base bearing, and the oblique angle labyrinth lip is deepened the labyrinth structure that the epaxial sealing groove formed in the base bearing, the excircle contact of contact lip and base bearing inner circle. The fluid lubricating grease in the main bearing cavity flows through the left labyrinth structure, so that the pressure and the throughput of the fluid lubricating grease are reduced, the pressure of the fluid lubricating grease of a closed surface formed by the contact lip and the main bearing inner ring in a contact mode is reduced, the closed surface formed by the contact lip and the outer circle of the main bearing inner ring in a contact mode can be prevented from being formed by the contact lip and the outer circle of the main bearing inner ring in a contact mode. The one-way labyrinth on the right further prevents the fluid lubricating grease passing through the contact lip and the closed surface of the outer circle of the inner ring of the main bearing, and prevents external dust, water and salt mist from entering the inner cavity of the bearing, thereby blocking a channel between an external space and the inner part 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 fig. 1, the utility model comprises a base body 5, a sealing ring and a linear locking spring 4; the base body 5 is made of cloth-sandwiched rubber, is of an annular structure and is arranged on an outer ring of the main bearing. The sealing washer excircle splice with the hole of base member 5, be equipped with annular spring mounting groove on the sealing washer excircle, linear locking spring 4 cramps the sealing washer in arranging spring mounting groove in. Be equipped with contact lip 2 and two oblique angle labyrinth lips 1, 3 on the inner wall of sealing washer, contact lip 2 is located between oblique angle labyrinth lip 1 and the oblique angle labyrinth lip 3, contact lip 2 be used for with the contact of main bearing inner circle excircle, oblique angle labyrinth lip 1 and oblique angle labyrinth lip 3 are used for imbedding the seal groove formation labyrinth structure on the main bearing inner circle. Bevel labyrinth lips 1 and 3 are made of hydrogenated nitrile rubber.
The working principle of the utility model is as follows:
As shown in figure 2, during the use of the utility model, the utility model discloses a base member 5 is installed on the outer lane of base bearing, and bevel angle labyrinth lip 1 and bevel angle labyrinth lip 3 go deep into the labyrinth structure that the epaxial sealing groove of corresponding base bearing circle formed, the excircle contact of contact lip 2 and base bearing inner circle. The fluid lubricating grease in the main bearing cavity flows through the left labyrinth structure, so that the pressure and the throughput of the fluid lubricating grease are reduced, the pressure of the fluid lubricating grease of a closed surface formed by the contact of the contact lip 2 and the main bearing inner ring is reduced, the closed surface formed by the contact lip 2 and the outer circle of the main bearing inner ring is enabled to be in contact, and the closed surface formed by the contact lip and the outer circle of the main bearing inner ring can be prevented.
