The magnetic suspension motor rotor cooling fan fixation structure comprises a rotor, a fixation sleeve, a cooling fan, a fixation sleeve fixation screw, a cooling fan fixation screw, a counterweight screw and bearings, wherein the two bearings sleeve the rotor, the fixation sleeve is fixedly connected with the bottom end of the rotor through the fixation sleeve fixation screw, one end wall of the fixation sleeve abuts against the bearings so as to press the two bearings against the rotor, the cooling fan is arranged on the fixation sleeve, the cooling fan fixation screw successively passes through the cooling fan and the fixation sleeve and is in threaded connection with the rotor, and the counterweight screw is in threaded connection with the cooling fan; the fixation sleeve is provided with a projection portion, the cooling fan is provided with a groove portion, and the projection portion is arranged in the groove portion; and the cooling fan is circumferentially provided with a plurality of counterweight threaded holes. The installation is simple, through bidirectional cooperation of the fixation sleeve, radial unbalance of the cooling fan is reduced, the counterweight threaded holes in the cooling fan facilitate counterweight balance of the rotor, and the dismounting is simple.
Description
Technical field：
The present invention relates to a kind of magnetic suspension motor rotor cooling fan fixed structure.
Background technology：
The cooling fan of magnetic suspension motor rotor is the important component in magnetic suspension motor, carries cooling motor temperature
Effect.Its operation principle is, with the rotation of rotor, the high-temperature gas in motor to be extracted out, reaches the purpose of cooling.Cooling wind
The amount of unbalance of fan, degree of stability each depend on the precision of installation and the precision of balancing.
Therefore, it is necessory to be improved to solve the deficiency of prior art to prior art.
The content of the invention：
The present invention is to provide a kind of magnetic suspension motor rotor cooling wind to solve the problems, such as above-mentioned prior art
Fan fixed structure.
The technical solution adopted in the present invention has：A kind of magnetic suspension motor rotor cooling fan fixed structure, including rotor,
Fixed cover, cooling fan, fixed cover fixing screws, cooling fan fixing screws, counterweight screws and bearing, bearing is equal described in two
It is sheathed on rotor, fixed cover is fixedly connected on the bottom of rotor by fixed cover fixing screws, and an end wall of fixed cover is supported
Touch on bearing, and two bearings are contacted on rotor, cooling fan is placed on fixed cover, and cooling fan fixing screws are worn successively
Supercooling fan and fixed cover are simultaneously threaded on rotor, and counterweight screws are threaded in cooling fan；
The fixed cover is provided with lug boss, and cooling fan is provided with concave part, lug boss is placed in concave part；
Some counterweight screwed holes are located on the circumferencial direction of the cooling fan.
Further, the cooling fan is provided with through hole, and the hexagonal fixing end in fixed cover fixing screws is placed in this and leads to
In hole.
Further, the rotor is provided with stage portion, and fixed cover contacts in the stage portion bearing.
The present invention has the advantages that：Simple installation of the present invention, by the two-way cooperation of fixed cover, reduces cooling wind
The amount of unbalance of radial direction is fanned, the counterweight screwed hole in cooling fan facilitates the balancing of rotor, fixed cover fixing screws and cold
But fan fixing screws, respectively fix two kinds of parts, even if cooling fan is damaged, dismounting also can be relatively simple.
Brief description of the drawings：
Fig. 1 is structure chart of the present invention.
Fig. 2 is structure chart of the middle (center) bearing of the present invention on rotor.
Specific embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.

With.
Such as Fig. 2, fixed cover 2 is also limited in pairs in addition to auxiliary installs cooling fan 3 together with the step surface of rotor 1
The axial internal clearance of bearing, general warranty a-b=0.4mm, in case clashing into magnetic bearing when the sub- start and stop of rotation stop or emergency case, is played
Protective effect.
The 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, these improvement also should be regarded as of the invention
Protection domain.
