Abstract
The utility model relates to a horizontal type three-fulcrum single shaft structure. A radial thrust bearing, a first radial bearing and a second radial bearing are arranged on a main shaft of a machine body. A rotor is installed on the main shaft between the radial thrust bearing and the first radial bearing. A flywheel is installed on the main shaft between the first radial bearing and the second radial bearing. Three bearings are adopted in the whole unit, a base plate is adjusted to be horizontal, the rotor which is the heaviest piece of a rotating part and the flywheel are rotated to be respectively placed between the three bearings, the single shaft structure is adopted in the whole unit, and thus the rigidity of the main shaft is enhanced, the operation of the unit is stable, cost is saved, and meanwhile, the axis adjustment difficulty of the main shaft is lowered, and the installation and debugging time of the unit is shortened.
Description
Technical field
The utility model belongs to the hydro-electric power generating equipment technical field, relates to a kind of horizontal three fulcrum single axle structures that are applicable to big-and-middle capacity horizontal hydrogenerator.
Background technique
The two fulcrum single axle structures of the in the past general employing of middle-size and small-size horizontal hydrogenerator group or four fulcrum double joint axle construction, but for big-and-middle-sized horizontal hydrogenerator group, because unit rotating part weight is large, and be that the rotary inertia that guarantees unit satisfies unit accent guarantor calculation requirement, also need increase flywheel weight, therefore the main shaft rigidity of two fulcrum single axle structures can not satisfy unit safety stable operation requirement; And the main-shaft axis of two axle construction of four fulcrums installation adjusting process is more complicated than single axle, and the adjustment time is long.
The model utility content
In order to overcome the above-mentioned shortcoming of prior art
,The utility model provides a kind of structure structure stable, the horizontal three fulcrum single axle structures of easy-to-install.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of horizontal three fulcrum single axle structures, main shaft is provided with radial-thrust bearing, radial bearing one and radial bearing two on body, rotor is installed on the main shaft between radial-thrust bearing and the radial bearing one, and flywheel is installed on the main shaft between radial bearing one and the radial bearing two.
Base is equipped with in bottom at body.
The beneficial effects of the utility model are: whole unit adopts three bearings, adjust level at base plate, the heaviest piece rotor of rotating part, divided flywheel other places are between three bearings, whole unit adopts the single axle structure, improve the main shaft rigidity, make the operation of unit more stable, saved cost, reduce simultaneously the main-shaft axis adjustment difficulty, shortened the Installation and Debugging time of unit.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-base, 2-main shaft, 3-radial-thrust bearing, 4-rotor, 5-radial bearing one, 6-flywheel, 7-radial bearing two.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1
,A kind of horizontal three fulcrum single axle structures, main shaft 2 is provided with radial-thrust bearing 3, radial bearing 1 and radial bearing 27 on body, rotor 4 is installed on the main shaft 2 between radial-thrust bearing 3 and the radial bearing 1, flywheel 6 is installed on the main shaft 2 between radial bearing 1 and the radial bearing 27, in the bottom of body base 1 is housed simultaneously.
The utility model is installed on the base plate after three bearings are adjusted level, rotor, runner, flywheel are positioned on the bearing after packing into separately main shaft, because of the weight ratio of rotor and flywheel larger, so be distributed in the middle of three bearings, can greatly improve like this rigidity of main shaft, its structure is more more stable than two fulcrums, and whole installation process has been lacked the connection of main shaft than the two main shafts of four fulcrums, install adjust more convenient.
The utility model has improved the main shaft rigidity, makes the operation of unit more stable, has saved cost, has reduced simultaneously the main-shaft axis adjustment difficulty, shortens the Installation and Debugging time of unit.
