Description
Technical field
The invention belongs to magneto technical field, more particularly to a kind of big-and-middle-sized magneto rotating shaft fixed structure.
Background technology
More permanent magnet is embedded in big-and-middle-sized permanent magnet machine rotor, rotor has very big magnetic.Rotor typically can only be in work
Factory is penetrated, and slightly imprudence stator and rotor will be adsorbed onto together, and separation is extremely difficult.Existing structure, after bearing fault
Positioning rotor can not be supported, once bearing fault can only also return to factory repair, the unnecessary time is caused or even economically wastes.
The content of the invention
It is an object of the invention to provide a kind of magneto rotating shaft fixed structure, and rotor supports are determined when solving magneto bearing fault
The problem of position.
To achieve the above object, the present invention adopts the following technical scheme that：Magneto rotating shaft fixed structure, including magneto
End cap and rotating shaft, rotating shaft outer ring are arranged with the cushion block of annular, and end cap is annular steel plate, and the side of end cap is provided with annulus post,
Annulus post one end is fixedly connected with end cap, and rotating shaft and thereon cushion block are respectively positioned in annulus post, rotating shaft, cushion block, annulus post and end cap
To be coaxially disposed, three bolts are circumferentially at least uniformly arranged on annulus post, annulus post corresponds to each bolt and is equipped with screwed hole,
Bolt is arranged on corresponding screwed hole, and the end of each bolt is stretched into annulus post and offseted with cushion block, and cushion block is folded in institute
Have between bolt.
The stopper slot of annular is provided with around the outer peripheral surface of cushion block, the end of the bolt is stretched into stopper slot and is against stopper slot
Groove bottom on.
Described rotating shaft one end is stretched out outside end cap from the annular distance of end cap.
Magneto rotating shaft fixed structure of the present invention, an annulus post is welded on end cap, the auger shell pit on annulus post,
Bolt is screwed on screwed hole.Before bearing in dismounting rotating shaft, cushion block is placed between bolt and rotating shaft, then tightens bolt,
Make block grip between two bolts, and then fixed rotating shaft, bearing is now dismantled again, and stator and rotor will not be then adsorbed onto together.
In the bolt that comes loose after new bearing installs, circular steel cushion block is taken out, solves rotor supports during magneto bearing fault
The problem of positioning.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is Fig. 1 right view；
In figure：End cap 1, bolt 2, annulus post 3, stopper slot 4, annulus post 5, rotating shaft 6.
Embodiment
As the magneto rotating shaft fixed structure shown in Fig. 1 and Fig. 2, including the end cap 1 of magneto and rotating shaft 6, the end
Lid 1 and rotating shaft 6 are the part of magneto, and end cap 1 is the end cap on the casing of magneto.
The outer ring of rotating shaft 6 is arranged with the cushion block 5 of annular, and the outer peripheral surface around cushion block 5 is provided with the stopper slot 4 of annular.
End cap 1 is annular steel plate, and the axial side of end cap 1 is provided with annulus post 3, and annulus post 3 is that cross section is annular
Cylinder, annulus post 3 are axially penetrating cylinder, and 3 axial one end of annulus post is fixedly connected by welding with end cap 1.
Cushion block 5 in rotating shaft 6 and rotating shaft 6 is respectively positioned in annulus post 3, and rotating shaft 6 and cushion block 5 are arranged at intervals with annulus post 3,
Rotating shaft 6, cushion block 5, annulus post 3 and end cap 1 are to be coaxially disposed, i.e. rotating shaft 6, cushion block 5, annulus post 3 and end cap 1 four
Central axis collinearly set.
It is uniformly distributed along the circumference on annulus post 3 and three bolts 2 is set, the corresponding each bolt 2 of annulus post 3 is equipped with screwed hole, spiral shell
Pit is through hole, and bolt 2 is arranged in corresponding screwed hole, and for bolt 2 to be radially arranged, the bolt head of bolt 2 is located at annulus
The outside of post 3.Certainly, the present invention is not limited to above-mentioned form, and bolt can be arranged as required to more than three.
The end (end for referring to the shaft of bolt 2) of each bolt 2 both pass through screwed hole stretch into annulus post 3 and with pad
Block 5 offsets, and the end of each bolt 2 stretches in stopper slot 4 and is against in the groove bottom of stopper slot 4, stopper slot 4
Located at cushion block 5 outer peripheral surface and for bolt 2 is carried out it is spacing.Cushion block 5 is folded between all bolts 2.
Described one end of rotating shaft 6 is stretched out outside end cap 1 from the annular distance of end cap 1, and the one end of rotating shaft 6 is stretched out by the annular distance of end cap 1
Outside the casing of magneto.
Magneto rotating shaft fixed structure of the present invention, it is first that the coaxial welding of annulus post 3 of steel is inside in the axle of end cap 1
Side, then according to the size of drawing requirement, tolerance, bolt 2 is manufactured by metalworking, and bored and bolt 2 on annulus post 3
The screwed hole of equivalent, general bolt 2 are no less than 3, and the nominal diameter of bolt 2 is not less than M10, when the diameter of rotating shaft 6 is very small
When can also bore smaller hole.Bearing fault in rotating shaft 6 or it is interim tear bearing open before, annular steel cushion block 5 is placed on
The inner side of bolt 2, screwing bolts 2, bolt 2 withstands cushion block 5, and then rotating shaft 6 is fixed, and now dismantles bearing, fixed,
Rotor will not be then adsorbed onto together, in the bolt 2 that comes loose after new bearing installs, take out annular steel cushion block 5.
