Description
Technical field
The utility model relates to technical field of wind power generation, more specifically, relates to the wind-powered electricity generation unit that a kind of wind-powered electricity generation set main shaft holds oil sealing and has it.
Background technique
The horizontal axis wind-driven generator group is a kind of structural type that extensively adopts both at home and abroad at present; In this type of wind power generating set; Main bearing plays considerable effect in whole Transmitted chains, and the effect of main-bearing oil seal is to prevent that grease is leaked to the bearing outside in the main bearing, causes the pollution of environment; The pollutants such as dust that prevent the outside again enter into bearing inside, cause the damage of bearing.
The horizontal axis wind-driven generator group main-bearing oil seal of existing technology adopts the traditional oils seal structure, because closure size is bigger, oil sealing often has spring ring provides enough impacting forces.The oil sealing of this type band spring is deviate from the unit running process spring coil of being hit by a bullet easily, causes seal failure, and the spring ring of deviating from is easy to get in the main bearing, causes main bearing to lose efficacy, and causes serious damage for whole unit.Adopt this type of that there is serious potential safety hazard in unshielded oil sealing of spring in unit operation.
The model utility content
The utility model purpose is to provide the protection of a kind of increase to spring ring, and the wind-powered electricity generation set main shaft of avoiding spring ring to deviate from oil sealing holds oil sealing and has its wind-powered electricity generation unit.
The utility model provides a kind of wind-powered electricity generation set main shaft to hold oil sealing, and comprising: the oil sealing main body comprises lip; Spring ring is used to strengthen the impacting force of said lip; Said oil sealing also comprises: protection portion, between said protection portion and said lip, form installing space, and said spring ring is contained in the said installing space and relies on the shape of said protection portion and said lip spacing.
Further, said lip comprises groove, forms said installing space between said protection portion and the said groove.
Further, said protection portion is a protective film.
Further, the sulfuration of said protection portion and said oil sealing main body is fixed as one.
Further, said oil sealing main body comprises outer ring portion that is formed by the canvas filler rubber material and the annular inner portion that is formed by rubber material, and said annular inner portion comprises said lip.
Further, said protection portion is formed by rubber material.
Further, said oil sealing main body embedded metal skeleton.
The utility model also provides a kind of wind-powered electricity generation unit, comprises that aforesaid wind-powered electricity generation set main shaft holds oil sealing.
Wind-powered electricity generation set main shaft according to the utility model holds oil sealing; Because spring ring is installed in the installing space that forms between the lip of protection portion and oil sealing main body; Can avoid spring ring because of fracture or improper causing be installed be in operation, reduce the risk of spring ring damage bearing.In addition; Because spring ring relies on the shape of protection portion and lip spacing; Be that spring ring is installed on the lip of oil sealing main body but does not fix with the oil sealing main body, but can free bend flexible, thereby guaranteed that spring ring can bring into play better effect when being fixed on the oil sealing main body.
Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is that the wind-powered electricity generation set main shaft of the utility model holds the oil seal structure schematic representation.
Embodiment
Below with reference to accompanying drawing and combine embodiment to specify the utility model.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
The oil sealing of present embodiment is as shown in Figure 1, comprising: oil sealing main body 1, spring ring 2 and protection portion.Oil sealing main body 1 comprises lip 121.Spring ring 2 is used to strengthen the impacting force of lip 121.Protection portion and oil sealing main body 1 are wholely set, and between protection portion and lip 121, form installing space, and spring ring 2 is contained in the installing space and relies on the shape of protection portion and lip 121 spacing.Because spring ring 2 is installed in the installing space that forms between the lip 121 of protection portion and oil sealing main body 1, can avoid spring ring 2 because of fracture or improper causing be installed be in operation, reduce the risk that spring ring 2 damages bearings.In addition; Because spring ring 2 relies on the shape of protection portion and lip 121 spacing; Be that spring ring 2 is installed on the lip 121 of oil sealing main body 1 but fixing with oil sealing main body 1; But can free bend flexible, thereby have guaranteed that spring ring 2 can bring into play better effect when being fixed on the oil sealing main body.
Oil sealing main body 1 is a loop configuration, cooperates with the endoporus and the main shaft 5 of housing 4, is fixed on main shaft 5 upper bearing (metal)s one side through the shaft shoulder.Oil sealing main body 1 can adopt integral molded plastic to be shaped.The outer ring portion 11 with housing 4 directly contacts of oil sealing main body 1 can be made up of canvas filler rubber, can also in owe metal frame to improve the rigidity of oil sealing main body 1, outer ring portion plays a part fixed support.The annular inner portion 12 that contacts with main shaft 5 of oil sealing main body 1 can be made up of rubber, and annular inner portion plays the oil sealing effect.Annular inner portion has comprised lip 121.Spring ring 2 can be connected to ring-type by single or many springs, is embedded in the groove on oil sealing main body 1 lip 121, and spring ring 2 provides certain impacting force can for lip 121, and lip 121 and main shaft 5 are closely cooperated, and plays the oil seal effect.Protection portion is into the protective film 3 of membrane structure in the present embodiment, and protective film 3 can be made up of rubber, cover on the spring ring 2, and reliable for intensity, protective film 3 preferably fixedly becomes one with 1 sulfuration of oil sealing main body, thus restraining spring circle 2 is deviate from groove.
Above embodiment should not constitute restriction to the utility model, and for example, because protection portion and 121 pairs of spring rings 2 of lip are spacing jointly, therefore, the groove on the lip 121 not necessarily; Protection portion also is not necessarily membrane structure, also can be when needed suitably whole thickening or with the position of spring ring 2 and lip 121 and the part thickening that shape adapts etc.; Also can adopt bonding be connected etc. between protection portion and the oil sealing main body.
Adopted the wind power generating set of above main-bearing oil seal, can not deviate from or the bad damage that causes main bearing because of spring ring.
Can find out that from above description the utility model the above embodiments have realized following technique effect: can avoid spring ring because of fracture or improper causing be installed be in operation, reduce the risk of spring ring damage bearing.In addition, spring ring is can free bend flexible, has guaranteed that spring ring can bring into play better effect when being fixed on the oil sealing main body.Further, protection portion and the sulfuration of oil sealing main body are fixed as one, and intensity is reliable.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
