Abstract
The utility model relates to a large power electric generator set, comprising a minicar engine and a power generator. The flywheel of the minicar engine is jointed with the shaft of the power generator through a coupler. The jointing mode that the engine flywheel of the large power electric generator set is jointed with the shaft of the power generator through the coupler is provided with stronger ability of the torque transmission and can bear the impact force of the engine crankshaft of the minicar. The jointing strength is competent for the conveying of the engine power of the minicar. Because the flywheel is not contacted directly with the shaft of the power generator in the jointing mode, the flywheel is connected indirectly with the shaft of the power generator through a clutch which is made from high strength plastic. So, in the process of power transmission, the power generator set does not generate stronger vibration and bigger noise.
Description
Technical field
The utility model relates to a kind of generating set, particularly the high-power generator group.
Technical background
Generating set mainly is made up of petrol engine and generator, domestic gasoline engine generator group all belongs to low moment of torsion at present, the small power generator group, wherein engine crankshaft and alternator shaft carry out rigid attachment (as shown in Figure 3) by a stay bolt, be that the engine crankshaft end portion is a cone, offer screwed hole along axis, alternator shaft offers the bolt via hole, the rotating shaft end portion offers taper hole along axis, the bolt via hole of stay bolt from alternator shaft passes, spin with the screwed hole of engine crankshaft end, engine crankshaft termination conical section is fastened on two conical surfaces are fitted tightly, thereby realize the rigid attachment of engine crankshaft and alternator shaft.Behind the ato unit, power passes to alternator shaft by this rigid attachment, makes generating set output electric energy.This kind connecting mode only is applicable to low moment of torsion, small power generator group, and for the high-power generator group of minicar engine as power, because the moment of torsion of engine crankshaft output is big, the impulsive force that engine crankshaft and alternator shaft coupling part are subjected to is very big, thereby makes the not competent so big impulsive force of intensity of this kind rigid attachment mode; And this kind rigid attachment mode makes generating set easily produce stronger vibration and bigger noise.
The utility model content
It is the high-power generator group of power with the minicar engine that the purpose of this utility model provides a kind of, make connecting mode between engine crankshaft and the alternator shaft can be competent at the moment of torsion output of minicar engine bent axle, reduce the vibration and the noise of generating set simultaneously.
High-power generator group described in the utility model comprises minicar engine and generator, and the flywheel of minicar engine connects by shaft coupling with alternator shaft.
Described shaft coupling is an annular, and it is sleeved on the alternator shaft, and is radially connected shaft coupling and alternator shaft are fastening along shaft coupling by screw; Coupling end-face and minicar engine flywheel end face are fitted, and are axially connected shaft coupling and flywheel are fastening along shaft coupling by screw.
The flywheel and the bent axle of minicar engine combine as a whole, and show so the rotation of bent axle is rotation with flywheel.
This connecting mode of engine flywheel and alternator shaft has stronger torque-transfer capability, can bear the impulsive force of minicar engine bent axle, and its linking intensity can be competent at the transmission of minicar engine power; And owing to this kind connecting mode flywheel does not directly contact with alternator shaft, but connect indirectly, so in the power transmission process, generating set can not produce stronger vibration and bigger noise by the shaft coupling of making by the highstrenghtpiston.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the structural representation of high-power generator group described in the utility model;
Fig. 2 is the cutaway view of A-A line among Fig. 1;
Fig. 3 is the structural representation of low moment of torsion small power generator group.
Embodiment
As shown in Figure 1 and Figure 2, this high-power generator group comprises minicar engine 1 and generator 7, and the flywheel 2 of minicar engine 1 connects by shaft coupling 4 with alternator shaft 6.This shaft coupling 4 is an annular, make by the highstrenghtpiston, radially offer the screw via hole of three band counterbores on it, and be evenly distributed on shaft coupling 4 peripheries, also offer the screw via hole of three band counterbores on it vertically, and be evenly distributed on shaft coupling 4 end faces.Radially offer three screwed holes on the alternator shaft 6, its position is corresponding with the screw via hole on the shaft coupling 4, offers three screwed holes on the flywheel 2 vertically, and its position is corresponding with the screw via hole on the shaft coupling 4.Shaft coupling 4 is sleeved on the alternator shaft 6, and by three soket head cap screws 5 along shaft coupling 4 radially with shaft coupling 4 and 6 fastening connections of alternator shaft; Shaft coupling 4 end faces and minicar engine flywheel 2 end faces are fitted, and by three soket head cap screws 3 along shaft coupling 4 axially with shaft coupling 4 and 2 fastening connections of flywheel.
Minicar engine 1 bent axle drives flywheel 2 rotations, drives alternator shaft 6 rotations by shaft coupling 4, thereby makes generator 7 output electric energy.
