Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the bearing seal filtration of wind power generating set of the present utility model and aerogenerator are further elaborated. It is to be understood that specific embodiment described herein is only in order to explain the utility model, and it is not used in restriction the utility model.
As shown in Figure 1, the bearing seal filtration of a kind of wind power generating set comprises main shaft 1, bearing 2, the filter element 4 of bearing support 3 and annular, bearing support 3 has the lubricating cavity 31 holding bearing 2, bearing 2 is sleeved on main shaft 1, and it is installed in lubricating cavity 31 by the port of lubricating cavity 31, sealing member 5 it is provided with between main shaft 1 and the port of lubricating cavity 31, with the gap sealed between the port of main shaft 1 and lubricating cavity 31, the position that filter element 4 is sleeved between main shaft 1 head bearing 2 and sealing member 5, and filter element 4 outer wall is connected on the inwall of lubricating cavity 31, it should be noted that, in operational process, filter element 4 can rotate relative to the inwall of main shaft 1 and/or lubricating cavity 31.
The foreign matter that port direction from lubricating cavity 31 is come when sealing member 5 damage occurs or be poorly sealed, can be stopped, prevent it from entering lubricating cavity 31 and bearing 2 is caused damage by such filter element 4.
The installation of filter element 4, can specifically adopt, on the outer wall of main shaft 1, its circumference be provided with groove 11, and filter element 4 is sleeved in groove 11. Can prevent filter element 4 from along the axial direction due of main shaft 1, displacement occurring on main shaft 1 like this, thus it is more accurate to make filter element 4 install position.
Alternatively, as shown in Figure 2, the surface of filter element 4 has multiple through hole 41 passed through for lubricating oil, and multiple through hole 41 is evenly arranged on filter element. Lubricating oil in such lubricating cavity 31 can flow to sealing member 5 by through hole 41, and then is lubricated by sealing member 5, extends the work-ing life of sealing member 5.
In real work, the breakage of sealing member 5 is very common problem, and sealing member 5 is generally outside framework oil seal, therefore the diameter of the diameter of the through hole 41 lip spring that needs to be less than in outside framework oil seal. When outside framework oil seal is damaged, can prevent lip spring chip in outside framework oil seal from entering into lubricating cavity 31 by through hole 41 like this.
Preferably, the material of filter element 4 can be elastic organic material (such as urethane, rubber etc.). Like this when main shaft 1 carries out relative rotation with bearing support 3, filter element 4 can between main shaft 1 and the inwall of lubricating cavity 31, produce elasticity distortion in real time, thus reduce the frictional force between the inwall of main shaft 1 and lubricating cavity 31, and then reduce the operating load that main shaft 1 carries out relative rotation with bearing support 3. More preferably, as shown in Figure 3, the cross-sectional shape of filter element 4 is annular, makes filter element 4 be the cylindrical body of hollow. The flexibility of filter element 4 can be strengthened like this so that it is more easily produce elasticity distortion.
As another kind of optional mode, as shown in Figure 4, filter element 4 comprises interior circle ring rack 42 and outer toroid support 43; Filter element 4 is sleeved on main shaft 1 by interior circle ring rack 42, and is connected on the inwall of lubricating cavity 31 by outer toroid support 43, is fixedly connected with filter screen 44 between interior circle ring rack 42 and outer toroid support 43. Can directly being stopped by the foreign matter that the port direction from lubricating cavity 31 is come by filter screen 44 like this, the lubricating oil in lubricating cavity 31 can flow to sealing member 5 by filter screen 44 simultaneously. Wherein, interior circle ring rack 42 and outer toroid support 43 can adopt elastic organic material to make, and its principle is identical with the principle described in alternatively, repeats no more herein.
For realizing goal of the invention, the utility model also provides a kind of aerogenerator, and this aerogenerator has the bearing seal filtration of the wind power generating set described in above embodiment.
The bearing seal filtration of the wind power generating set of above embodiment and the wind power generating set with this bearing seal filtration can prevent foreign matter from entering lubricating cavity effectively, thus avoid bearing and cause damage because of entering of foreign matter.
Above embodiment only have expressed several enforcement mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model patent scope. , it is also possible to make some distortion and improvement, it should be appreciated that for the person of ordinary skill of the art, without departing from the concept of the premise utility these all belong to protection domain of the present utility model. Therefore, the protection domain of the utility model patent should be as the criterion with claims.
