Abstract
The utility model discloses a sealing structure of a wind driven generator, in particular to a sealing structure for a slewing bearing of a large-scale fan, and the sealing structure has the advantages of long service life and high reliability. The sealing structure includes an outer ring (1), an inner ring (2), and a seal ring (3) arranged between the outer ring (1) and the inner ring (2), wherein a seal lip (4) of the seal ring (3) is assembled on the outer diameter of the outer ring (1), the seal lip (4) is compositely and dually set, and each lip of the seal lip is provided with two small lips. The sealing structure can effectively ensure the sealing performance, so that the service of the bearing can be guaranteed for more than 20 years.
Description
Technical field
The utility model relates to a kind of sealing configuration of wind-driven generator, particularly relates to a kind of high working life, high reliability and is applicable to the sealing configuration of large fan slewing bearing.
Background technique
The large fan slewing bearing is installed on the altitude plant that overhead moves more than tens meters and even 100 meters, requires bearing to have high bearing capacity and long working life, needs to guarantee the working life in 20 years.At the bearing run duration, sealing seems particularly important.The quality of sealing directly influences the working life in 20 years of bearing.Yet conventional bearing seal structure is difficult to satisfy this usage requirement, and turntable bearing commonly used is sealed with a lot of forms, but is single lip seal substantially.Under the abominable operating mode of external environment, sealing effect is not obvious, is easy to generate seal leakage, phenomenons such as the easy disengaging of seal ring, even adopt improved procedure: adhesive means, also play very limited effect.
The model utility content
The utility model is exactly in order to solve the problems of the technologies described above, and a kind of sealing configuration of large fan slewing bearing is provided, and purpose is the high reliability that reaches sealing, prolongs the working life of bearing.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of sealing configuration of large fan slewing bearing, it is to be made of outer ring, inner ring, the seal ring that is arranged between outer ring and the inner ring, and the sealing lip of seal ring is set up on the external diameter of outer ring, and sealing lip is compound lips, and every lip is provided with two microcheilias.
Described seal ring external diameter is provided with the convex projection, and the fitting surface of seal ring and seal groove is provided with damping tape.
Advantage of the present utility model and effect are as follows:
The utility model can effectively guarantee sealability, provides guarantee in working life more than 20 years for bearing reaches.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, outer ring, 2, inner ring, 3, seal ring, 4, sealing lip, 5, damping tape.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details, but protection domain of the present utility model is not limit by embodiment.
Shown in 1, the sealing configuration of the utility model large fan slewing bearing is to be made of outer ring 1, inner ring 2, the seal ring 3 that is arranged between outer ring 1 and the inner ring 2, the sealing lip 4 of seal ring 3 is set up on the external diameter of outer ring 1, radially forming interference fit with outer ring 1, sealing lip 4 is compound lips, and every lip is subdivided into the composite structure that is provided with two microcheilias substantially; Seal ring 3 external diameters are provided with the convex projection, have damping tape 5 on the fitting surface of seal ring 3 and seal groove.Sealing lips simultaneously all is compound lips, and promptly every lip is subdivided into the composite structure that is provided with two microcheilias substantially.
In order to prevent that outside rugged environment such as rainwater, sand and dust etc. from entering bearing and preventing the leakage of lubricating grease, contact the sealing configuration that end face is equipped with at bearing with extraneous: sealing lip is compound lips.Can prevent more that in order to guarantee that seal ring 3 is convenient to install seal ring 3 from coming off from groove, seal ring 3 external diameters are provided with the convex projection, have damping tape on seal ring 3 and face that seal groove cooperates.
Claims (2)
1. the sealing configuration of a large fan slewing bearing, it is characterized in that it is by outer ring (1), inner ring (2), is arranged on seal ring (3) formation between outer ring (1) and the inner ring (2), the sealing lip (4) of seal ring (3) is set up on the external diameter of outer ring (1), sealing lip (4) is compound lips, and every lip is provided with two microcheilias.
2. the sealing configuration of large fan slewing bearing according to claim 1 is characterized in that described seal ring (3) external diameter is provided with the convex projection, and seal ring (3) is provided with damping tape (5) with the fitting surface of seal groove.
