Abstract
The invention provides a flywheel blade mechanism for a single-bearing generator. The flywheel blade mechanism comprises a drive flywheel, a screw, a drive plate, a generator shaft, a bolt and a flywheel blade, wherein the flywheel blade comprises an annular sheet-like mounting substrate; a plurality of square blades with a certain thickness are uniformly distributed on the mounting substrate along the radial direction; the square blades are integrated with the mounting substrate by welding or casting; and the flywheel blade together with the drive plate are fixed on the end face of the power drive flywheel through the bolt. The flywheel blade mechanism provided by the invention is simple in flywheel blade structure, easy in manufacture and convenient in installation, and can reduce the use amount of materials and obviate the needs of a retaining ring and a key for the shaft. In addition, the flywheel blade and the drive plate are fixed on the end face of the drive flywheel together so as to realize stable operation, reduce vibration of the generator, reduce the occupied space and reduce the axial size of the generator; and the flywheel blade is not mounted on the shaft so as to reduce force on the shaft, properly reduce the shaft diameter and lower the production cost.
Description
Technical field
The present invention relates to electric generator structure, be meant that specifically a kind of single shaft holds generator and uses the flywheel fan blade mechanism.
Background technique
Fan blade mainly plays thermolysis in generator; The generation current machine blade is to be fixed on the alternator shaft through modes such as hot jacket, keys mostly, and the blade structure complicacy is various, and materials used is many; Rotating shaft is stressed big; Therefore generator need increase its axial dimension and rotating shaft diameter, has increased the cost of production of generator, and vibrations are big during generator work.For this reason, we provide a kind of single shaft to hold the flywheel fan blade mechanism that generator is used.
Summary of the invention
A kind of single shaft provided by the invention holds generator and uses the flywheel fan blade mechanism, and its purpose is to overcome existing generator fan blade and has shortcomings such as above-mentioned deficiency.
The technological scheme that the present invention adopts is following:
A kind of single shaft holds generator and uses the flywheel fan blade mechanism, comprises power flywheel, screw, driving plate, alternator shaft, bolt and flywheel fan blade.Said flywheel fan blade comprises annular slice installation base plate; A plurality of certain thickness square blades that have radially evenly distribute on this installation base plate; Square blade is welded or cast solid with base plate is installed, and flywheel fan blade and driving plate together are fixed by bolts on the power flywheel end face.
Particularly; Aforementioned power flywheel end face is provided with a location seam is installed, and on same circumference, is evenly distributed with a plurality of tapped holes on the interior edge face of installation seam, on same circumference, also is distributed with a plurality of tapped holes on the alternator shaft one end end face; The driving plate diameter is identical with power flywheel installation seam nominal size; Be distributed with inner ring circumferential apertures and outer ring circumferential apertures on the driving plate end face, inner ring circumferential apertures and alternator shaft tapped hole are complementary, and fix with said screw and alternator shaft; Outer ring circumferential apertures and power flywheel tapped hole are complementary, and to be bolted on the power flywheel.
Further, aforementioned flywheel fan blade is installed on the base plate and is distributed with and corresponding, the sizable mounting hole in power flywheel tapped hole position.
Can know through the above-mentioned description of this invention, and comparing with prior art, the invention has the advantages that: the flywheel blade structure of this flywheel fan blade mechanism is simple, easy to manufacture; Simple installation, materials used is few, saves shaft block ring and key; Flywheel fan blade and driving plate together are fixed on the power flywheel end face, and stable working has reduced the vibrations of generator; It is little to take up room, and can reduce the axial dimension of generator, and the flywheel fan blade is not installed in the rotating shaft; Rotating shaft is stressed to be reduced, and can suitably reduce the rotating shaft diameter, has reduced cost of production.
