Abstract
The utility model provides a wind-driven generator base which is characterized in that a bearing seat of a wind-driven generator impeller main shaft and a main frame are a whole body. The optimum implementation solution is that when observing the base from the top portion, a top hole is arranged between two bearings, the minimum distance between hole edges is at least 300mm, and the concrete size of the top hole is correlated with the contour dimension of a fitting which needs to pass through the hole. Compared with an existing mode that a bearing seat and a main frame are separated, the wind-driven generator base has the advantages that the weight of the base is lightened, the structure is simplified, the intensity is reinforced, thereby being capable of bearing bigger load, and the rigidity is better and is not easily deformed. The wind-driven generator base has less processing surfaces and better machine processing manufacturability, thereby reducing workload of machine processing and lowering production cost, in addition, the wind-driven generator base has better casting manufacturability, and lowers the occurrence rate of defective works.
Description
Technical field
The utility model relates to a kind of base of wind-driven generator.Particularly, the base of the utility model indication is meant that the bearing support of wind-driven generator impeller spindle and mainframe are an integral body.
Background technique
Wind-driven generator provides the main energy sources that is convertible into electric energy and is used for electrical network, by driving generator, realizes the conversion of wind energy to electric energy in wind-driven generator.In recent years, along with the enhancing of environmental consciousness and the support of national policy, the exploitation of clean reproducible energy receives increasing concern.Along with the development of wind generating technology, the capacity of wind power generating set constantly increases, and particularly in recent years along with the appearance of domestic MW class blower fan, the weight of blower fan also is the trend that enlarges gradually.
Yet, for powerful wind-driven generator, when impeller obtains energy from wind also with big loading on component of machine.These load finally will pass to pylon, and all component between impeller and pylon all will bear these big load.Therefore, need have enough intensity as bearing support and mainframe.Excessive assembly error of bearing support and base and too small rigidity in addition, thus can influence the load of each parts on the Transmitted chains reduce they self and Transmitted chains on life-span of component, so bearing support and base need possess enough assembly precisions and rigidity.
The base of the wind-driven generator of prior art is bearing support and mainframe difference casting processing, by flange the two is connected.Since need machining bearing seat and base respectively, higher to requirement on machining accuracy; On the other hand, by bolt flange is connected, its coupling stiffness also be cannot say for sure to demonstrate,prove.And the increase of parts such as flange causes the weight of wind-driven generator and the increase of cost.
Summary of the invention
The utility model provides a kind of base of wind-driven generator, it is characterized in that the bearing support of wind-driven generator impeller spindle and mainframe are as a whole.
Realize that optimum scheme of the present utility model is, during from the described integrated form base of top view, have an apical pore between two bearings, the minimum range between peritreme is 300mm at least.The purposes of this apical pore be for convenient install, the dismounting bearing shaft is set to locating element, Sealing and lubricating fitting etc., the concrete size of apical pore is relevant with the spare part outside measurement that needs to pass through this apical pore.
The mode of separating with existing bearing support mainframe is compared, base front end described in the utility model is used to install two bearings that support impeller spindle, be delivered on the base by main shaft and fore bearing, rear bearing from the non-load of reversing around the axle center of impeller, can improve the transmission of load, thereby reduce the additional load of each parts on base and the Transmitted chains; And the seat hole of two bearings can process on same machining apparatus, has higher positional accuracy, can improve the assembly precision of base and bearing.
Base weight described in the utility model alleviates to some extent and stronger rigidity is arranged, and is not yielding, and working surface still less, has better process for machining, thereby reduce the machining workload and reduce production costs; In addition, removed adpting flange, weight alleviates to some extent, and structure is simplified, and possesses better intensity bearing big load, and has better casting manufacturability, reduces the occurrence rate of reject.
