Abstract
The utility model relates to a connecting device of a main shaft and a hub of a wind generating set. The connecting device of the main shaft and the hub of the wind generating set is provided with the hub and the main shaft, a plurality of taper holes corresponding mutually are evenly formed in the joint part of the end face of the hub and the flange face of the main shaft along an outer circle, after pre-assembly is carried out on the hub and the main shaft, a plurality of taper pins are inserted into the corresponding taper holes of the hub and the main shaft, and the flange face of the main shaft and the end face of the hub are pressed tightly through bolts. The taper pins are inserted into the corresponding taper holes of the hub and the main shaft, and then the bolts are screwed down through specified torque. Due to the fact that the taper pins can share shear force of the connecting bolts in the circumferential direction, the possibility that the bolts are sheared off is reduced, and working conditions of the bolts are improved.
Description
Technical field
The utility model relates to a kind of main shaft of wind power generating set and the connection set of wheel hub.
Background technique
Traditional wind generator unit wheel hub relies on a circle bolt to be connected with main shaft, by pretension bolt supported flange face, rely on the overall viewing range of two flanged surfaces, because the friction factor of steel and spheroidal graphite cast iron is lower, bolt pretightening is very big, bolt also will bear the moment of flexure that impeller passes in addition, and the operating conditions of bolt is very harsh.Often arrange the bolt of maximum quantity in the design and use large diameter as far as possible bolt still to be difficult to guarantee enough safety coefficient.The situation that bolt is broken happens occasionally, in case bolt failure just may cause whole impeller to be thrown, causes heavy economic losses.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of main shaft of wind power generating set and the connection set of wheel hub are provided, reduce the possibility that bolt is cut off.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of main shaft of wind power generating set and the connection set of wheel hub, have wheel hub, main shaft, the end face of described wheel hub offers a plurality of mutual corresponding taper holes with the joining portion of the flanged surface of main shaft equably along cylindrical, described wheel hub and main shaft carry out after the preassembly a plurality of taper pins being inserted in main shaft and the wheel hub taper hole corresponding, and the flanged surface of main shaft and the end face of wheel hub are compressed by bolt.
The beneficial effects of the utility model are: the utility model inserts in main shaft and the wheel hub taper hole corresponding with a plurality of taper pins, and the moment of torsion with regulation screws bolt then.Because taper pin can be shared connecting bolt circumference aspect shearing force, thereby has reduced the possibility that bolt is cut off, and has improved the working condition of bolt.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Wherein: 1. wheel hub, 2. main shaft, 3. taper hole, 4. taper pin.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of main shaft of wind power generating set and the connection set of wheel hub, have wheel hub 1, main shaft 2, the end face of wheel hub 1 offers a plurality of mutual corresponding taper holes 3 with the joining portion of the flanged surface of main shaft 2 equably along cylindrical, wheel hub 1 carries out after the preassembly a plurality of taper pins 4 being inserted in main shaft 2 and wheel hub 1 taper hole corresponding 3 with main shaft 2, and the end face of the flanged surface of main shaft 2 and wheel hub 1 is compressed by bolt.
The utility model inserts in main shaft 2 and wheel hub 1 taper hole corresponding 3 with a plurality of taper pins 4, and the moment of torsion with regulation screws bolt then.Because taper pin 4 can be shared connecting bolt circumference aspect shearing force, thereby has reduced the possibility that bolt is cut off, and has improved the working condition of bolt.
Be enlightenment with above-mentioned foundation desirable embodiment of the present utility model, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
