Background technology：
When magneto installs rotor, due to the attraction of rotor 200 and stator 300, rotor and bearing inner race (upper bearing (metal)
400 with lower bearing 500) orientation problem it is often more intractable, once rotor 200 and bearing inner race produce collision, it is likely that
Bearing can be damaged, for angular contact bearing.
For ease of installation, after existing assembling scheme typically first assembles rotor and the bearing of certain one end in place, then enter
The installation of another end bearing of row.I.e.：
1) rotor 200 first assembles rotor 200, upper bearing (metal) 400, top chock and upper end cover before stator 300 is inserted
It is fixed, it is ensured that with upper bearing (metal) 400 relative motion will not occur for rotor 200；2) then, by lower bearing 500, bottom end cover 600 and
Step is assemblied on motor case.3) lift again 1) in complete assembling rotor 200, upper bearing (metal) 400, top chock and
Motor upper cover part, rotor 200 is passed through stator 300, complete to assemble with lower bearing 500.Due to rotor 200 and upper and lower axle
The assembling held is higher to positioning accuracy request, and above-mentioned three steps installation method can avoid bearings at both ends while need pinpoint
Situation.
For ensure rotor 200 axial location be accurately positioned to lower bearing 500, prior art frequently with mode be
An extending shaft 1 (such as Fig. 1) is threadedly coupled on rotor 200, in the concentric insertion lower bearing 500 of extending shaft 1, then by external
Plant equipment pulls extending shaft 1, finally realizes that rotor 200 is assembled in lower bearing 500.Due to rotor 200 and lower bearing 500 it
Between for interference fit, therefore pull extending shaft 1 during, the Internal and external cycle of lower bearing 500 can be caused opposite by both direction
Power, therefore lower bearing 500 can be damaged.Cost needed for other external plant equipment is higher.

Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figures 2 to 6, the present invention discloses a kind of rotor mounting tool for magneto, and the frock is used for will
Rotor 200 is installed in the lower bearing 500 of magneto in the magneto, and the lower end of the rotor 200 is threaded with
Extending shaft 1, the extending shaft 1 are arranged in lower bearing 500, including pedestal 2, dismounting set 3, driving plate 4 and limited block 5, pedestal 2 are logical
Cross screw to be fixedly connected with the bottom end cover 600 in magneto, and the upper end of pedestal 2 is connected on the inner ring of lower bearing 500, is prolonged
Axis direction of the bottom of major axis 1 along pedestal 2 is through pedestal 2, and on the base 2, driving plate 4 is solid for the threaded connection of dismounting set 3
Covered due to dismounting on 3 lower surface, and one end of driving plate 4 is connected on extending shaft 1, limited block 5 is fixed on the upper of dismounting set 3
On end face, and one end of limited block 5 is stretched on the outer wall of pedestal 2.
Driving plate 4 includes the plate body 41 of two semicircle shapes, and the second neck 42, the second neck are provided with the circle centre position of plate body 41
42 are connected in the first neck 14 in the circumferential wall of extending shaft 1, and gap coordinates between the second neck 42 and the first neck 14.
Limited impression 21 is provided with the outer circle wall of pedestal 2, limited impression 21 cooperates with limited block 5, for pair
The movement travel of extending shaft 1 is limited, and then rotor 200 is accurately assembled in lower bearing 500.
Limited block 5 includes the body 51 of a strip, upper and lower ends 90 ° of bendings in the opposite direction of body 51, and on
End forms position-limited edge 53, and lower end forms connection side 52, and position-limited edge 53 is stretched in limited impression 21.
Lower bearing 500 is carried out for ease of preferably spacing, boss portion 22, boss portion 22 are provided with the upper surface of pedestal 2
It is connected on the inner ring of lower bearing 500.
For ease of rotation dismounting set 3, rotary handle 31 is welded with the outer wall of rotation dismounting set 3.
In use, pedestal 2 is fixed on bottom end cover 600, and the boss portion 22 on pedestal 2 is contradicted in lower bearing
On 500 inner ring, extending shaft 1 is threaded on the bottom surface of rotor 200, and limited block 5 is pushed into the top of limited impression 21,
Then driving plate 4 will be connect to be fixed on the lower surface of dismounting set 3, and cause driving plate 4 to be connected in the first neck 14 of extending shaft 1
It is interior.Rotary handle 31 is rotated, dismounting set 3 is driven extending shaft 1, guided rotor 200 continues to move downward.Boss on pedestal 2
The inner ring of lower bearing 500 is withstood in portion 22, is avoided in assembling process, and downward power is born in the outer ring of lower bearing 500, in turn results in
The damage of lower bearing.
Rotation can effectively transmit downward power to dismounting set 3 on the base 2, make rotor 200 overcome resistance to move downward.
Limited block 5 and limited impression 21 are used cooperatively, and after rotor 200 can be made to assemble in place, prevent the interior of rotor conquassation lower bearing 500
Circle.
When limited block 5 covers stroke, that is, represent rotor 200 and assemble in place, now remove driving plate 4, dismounting set 3 successively,
Limited block 5, pedestal 2, extending shaft 1 is finally removed, installation bearing cover completes rotor installation.
The present invention can be that rotor assembling provides enough tractions in place after guided rotor and lower bearing complete centering
Power.Next rotor needs to overcome frictional resistance caused by elastic conjunction after accurately feeling relieved with lower bearing, now dismounting set
Screw thread between pedestal can efficiently transmit the drag force overcome needed for frictional force.Rotor is pounded to bearing production so as to avoid striking
It is raw to destroy.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
