Abstract
The invention discloses a kind of frock being used for rotor in magneto and lower bearing assembling, including axis body, threaded joints and the prismoid section with small end face and large end face, the left end of the axis body is fixedly connected with the small end face of prismoid section, and threaded joints are fixedly connected on the circle centre position of large end face in prismoid section；The first neck for clamping driving plate is provided with axis body.The present invention can ensure in rotor coaxial heart press-in lower bearing, avoid causing rotor to collide with lower bearing because of rotor displacement, therefore can damaging rotor or lower bearing.
Description
Technical field：
The present invention relates to a kind of frock being used for rotor in magneto and lower bearing assembling.
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, such as Fig. 1.Due to rotor 200 with
The assembling of upper and lower bearing is higher to positioning accuracy request, and above-mentioned three steps installation method can avoid bearings at both ends while need essence
It is determined that the situation of position.
But it is existing using aforesaid way assembling rotor when, due to gap be present between rotor 200 and stator 300, because
During this rotor 200 press-in lower bearing 500, it is impossible to complete under ensureing that axis direction of the rotor 200 along lower bearing 500 enters
In bearing 500, once shifting, due to the magnetic force of rotor 200, then rotor 200 can be caused to be collided with lower bearing 500,
Therefore can damaging rotor 200 or lower bearing 500.
The content of the invention：
The present invention is to provide a kind of be used for rotor in magneto to solve the above-mentioned problems of the prior art
With the frock of lower bearing assembling.
The technical solution adopted in the present invention has：A kind of frock being used for rotor in magneto and lower bearing assembling,
Including axis body, threaded joints and the prismoid section with small end face and large end face, the left end of the axis body and the small end of prismoid section
Face is fixedly connected, and threaded joints are fixedly connected on the circle centre position of large end face in prismoid section；
The first neck for clamping driving plate is provided with axis body.
Further, the diameter of small end face is more than or equal to the diameter of axis body in the prismoid section.
Further, the axis body, threaded joints and prismoid section are integrally formed.
Further, the frock is integrally made of stainless steel.
The present invention has the advantages that：
1) rotor is prevented in assembling process, may be attracted each other caused collision with stator.Because prismoid section with
It is that small―gap suture coordinates between lower bearing, so prismoid section can move freely upwards in lower bearing interior axle, but can not in radial direction
Larger skew, so as to prevent the collision of rotor and stator.
2) being capable of guided rotor and lower bearing completion positioning.Because, there is certain taper in one end that axis body is connected with rotor
(prismoid section), the size of prismoid section large end face is more than axis body, is slightly less than the size of armature spindle socket end, although under axis body size is less than
It bearing inner race, can not realize that centering requires, but gradually can be guided rotor to lower bearing central to realize by prismoid section
Centering demand.It is due to that prismoid section is installed in the presence of certain in itself with rotor on axis body why to be slightly less than the size of armature spindle socket end
Position error, enough guided rotors enter lower bearing to the chamfering of the taper fit rotor tip of prismoid section.
Brief description of the drawings：
Fig. 1 is the assembling schematic diagram of rotor and upper and lower bearing in the prior art.
Fig. 2 is structure chart of the present invention.
Fig. 3 is application structure figure of the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
Such as Fig. 2 and Fig. 3, the present invention discloses a kind of frock being used for rotor in magneto and lower bearing assembling, including
Axis body 11, threaded joints 12 and the prismoid section 13 with small end face and large end face, the left end of axis body 11 are small with prismoid section 13
End face is fixedly connected, and threaded joints 12 are fixedly connected on the circle centre position of large end face in prismoid section 13.
For ease of pulling axis body 11, the first neck 14 for clamping driving plate 4 is provided with axis body 11.
The diameter of large end face is slightly less than the diameter of the bottom surface of rotor 200 (i.e. armature spindle socket end) in prismoid section 13；Prismoid section 13
The diameter of middle small end face is more than or equal to the diameter of axis body 11.
To increase intensity of the present invention, axis body 11, threaded joints 12 and prismoid section 13 are integrally formed.Frock is not integrally using
Rust steel is made.
In use, threaded joints 12 are threaded at the lower surface axle center of rotor 200, and prismoid section 13 is placed in down
In bearing 500, the force arm of external plant equipment is connected with the first neck 14, and the first neck 14 provides the point of application.Prismoid section 13
The centering with the inner ring of lower bearing 500 can be completed with guided rotor 200, and axle is dimensioned slightly smaller than due to the large end face of prismoid section 13
The size of inner ring is held, therefore prismoid section 13 itself will not produce extra assembling resistance.
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.
