Description
Technical field
The utility model relates to a kind of generator set, specifically: relate to a kind of axle extend through flow type two fulcrum generator set.
Background technique
Along with the deep propelling of hydroelectric development, the utilization of extra low head hydroelectric resources will attain full development.Tubular unit will fully be used.As shown in Figure 1, tradition axle extend through flow type unit is installed in flywheel 5 between tubular turbine 1 and the generator 3, on flywheel 5 both sides main bearing 6 and spherical bearing 2 are set respectively, main bearing 6 is used for support flying wheel 5 weight, and the thrust of bearing tubular turbine 1, but can not adjust the deviation that bearing causes because of the assembling decentraction, spherical bearing 2 is used to support rotating part weight, and can adjust the deviation that diaxon causes because of the assembling decentraction, back at spherical bearing 2 is installed radial bearing 7 successively, the generator 3 and second radial bearing 8, the weight that the radial bearing 7 and second radial bearing 8 are used to bear generator 3 rotors.Be independently two equipment of generator 3 and water turbine 1 conduct, this structure also needs 4 bearings except that the supplemental support bearing of water turbine self, be main bearing 6 and spherical bearing 2 and two radial bearings, this makes the shaft system of unit complex structure, the installation and maintenance difficulty, the unit axial length is long, and the factory building span increases, and the power station investment cost is many.Returns of investment are few, had a strong impact on the utilization and the exploitation of middle-size and small-size extra low head hydroelectric resources.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of motor seal axle construction, its long service life and good sealing effect.
The technical solution of the utility model is as follows: a kind of axle extend through flow type two fulcrum generator set, comprise tubular turbine, spherical bearing, generator and flywheel, the rotating shaft of described tubular turbine and the rotating shaft of generator connect as one and become single-shaft configuration, described generator is near mounting spherical bearing in the rotating shaft of tubular turbine, described generator is away from the self-aligning radial bearing is installed in a side's of tubular turbine the rotating shaft, described flywheel is installed in the end of the rotating shaft of generator, described flywheel is positioned at the right of self-aligning radial bearing, described self-aligning radial bearing comprises radial support seat and bearing shell radially, described radially bearing shell is sleeved in the hole of radial support seat, the face that described radially bearing shell and radial support seated connection touch is a sphere, the left end installed thrust of described radially bearing shell watt, radially the right-hand member of bearing shell is installed deboost watt.
In technique scheme; the rotating shaft of described tubular turbine and the rotating shaft of generator connect as one and become single-shaft configuration; adopt a spherical bearing to support the weight of rotating part; adjust the deviation that diaxon causes because of the assembling decentraction; adopt the self-aligning radial bearing to bear unit rotating part weight; the face that described radially bearing shell and radial support seated connection touch is a sphere; promptly radially bearing shell cooperates with radial support seat sphere; can allow and drive radially by alternator shaft bearing shell meaning in office spatial position turns an angle; solved the problem that motor shaft part and tubular turbine shaft part axis can not overlap because of alignment error; in the left end installed thrust watt forward hydraulic thrust that is used to bear tubular turbine of bearing shell radially; at the right-hand member of bearing shell radially deboost watt is installed, is used to bear the reverse hydraulic thrust of tubular turbine.Simplify the shaft system of unit structure greatly, reduced the unit maintenance expense, shortened the unit axial length, reduced power station factory building span, saved the power station investment.
In technique scheme: the rotating shaft tapering interference fit of described flywheel and generator.
In technique scheme: described spherical bearing comprises supporting base and bearing shell, and described bearing shell is sleeved in the hole of supporting base, and the face that described bearing shell contacts with supporting base is a sphere.The face that described bearing shell contacts with supporting base is a sphere, be that bearing shell cooperates with the supporting base sphere, can allow that alternator shaft drives bearing shell and turns an angle in spatial position arbitrarily, solve the problem that motor shaft part and tubular turbine shaft part axis can not overlap because of alignment error.
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, has simplified the shaft system of unit structure greatly, has reduced the unit maintenance expense, has shortened the unit axial length, has reduced power station factory building span, has saved the power station investment.
