Description
Technical field：
The utility model is related to a kind of mounting structures of monoblock type thrust disc in magnetic suspension motor.
Background technology：
In existing magnetcisuspension floating centrifugal motor, the mode that thrust disc is fixed by bolts is fixed on the electric machine structure on rotor
When in use, since the rotating speed of magnetic suspension motor is higher, generally in 20000r/min or more, so thrust disc is connected by screw bolts
In operating for a long time, bolt can loosen, and there are certain hidden danger.
Utility model content：
The utility model is provided whole in a kind of magnetic suspension motor to solve the above-mentioned problems of the prior art
The mounting structure of formula thrust disc.
Technical solution used by the utility model has：The mounting structure of monoblock type thrust disc in a kind of magnetic suspension motor,
Including magnetic axis bearing, mandrel, radial direction magnetic bearing, lifting force magnetic bearing and lower thrust magnetic bearing, the radial direction magnetic bearing, lifting force
Magnetic bearing and lower thrust magnetic bearing are both secured in magnetic axis bearing, mandrel be supported on radial direction magnetic bearing, lifting force magnetic bearing and under
Further include thrust disc in thrust magnetic bearing, the thrust disc is sheathed on mandrel, and is interference fitted between thrust disc and mandrel,
One end of thrust disc is placed between lifting force magnetic bearing and lower thrust magnetic bearing；
The thrust disc includes an ontology, and the axis direction of the ontology is equipped with axis hole, the outer circle wall of ontology lower port to
Disk body is extended to form outside, which is placed between lifting force magnetic bearing and lower thrust magnetic bearing, the outer circle wall of ontology upper port
It extends outward to form and contradicts side.
Further, the thrust disc is made of No. 4140 steel.
The utility model has the advantages that：Thrust disc in the utility model uses monolithic construction, uses
The assembly technology that is full of is assemblied on mandrel, can be avoided at higher rotational speeds, the connection bolt looseness of thrust disc, and axial string occurs
Dynamic or resonance.Using whole thrust disc, part is reduced, it is easy to process, it can also simplify assembly technology.
Description of the drawings：
Fig. 1 is mounting structure structure chart of the utility model thrust disc in magnetic suspension motor.
Fig. 2 is the structure chart of thrust disc in the utility model.
Specific implementation mode：
The utility model will be further described below with reference to the accompanying drawings.
Such as Fig. 1 and Fig. 2, the utility model discloses a kind of mounting structure of monoblock type thrust disc in magnetic suspension motor, including
Magnetic axis bearing 1, mandrel 2, radial direction magnetic bearing 3, lifting force magnetic bearing 4, lower thrust magnetic bearing 5 and thrust disc 6, radial direction magnetic bearing 3,
Lifting force magnetic bearing 4 and lower thrust magnetic bearing 5 are both secured in magnetic axis bearing 1, and mandrel 2 is supported on radial direction magnetic bearing 3, lifting force
In magnetic bearing 4 and lower thrust magnetic bearing 5, thrust disc 6 is sheathed on mandrel 2, and is interference fitted between thrust disc 6 and mandrel 2, is pushed away
One end of power disk 6 is placed between lifting force magnetic bearing 4 and lower thrust magnetic bearing 5, and thrust disc 6 contacts on radial direction magnetic bearing 3.
Thrust disc is fixed top cover 7 and is made of No. 4140 steel.
Thrust disc 6 in the utility model is an integral structure, including an ontology 61, the axis direction of the ontology 61 are equipped with
The outer circle wall of axis hole, 61 lower port of ontology extends outward to form disk body 63, which is placed in lifting force magnetic bearing 4 and is pushed away under
Between power magnetic bearing 5, the outer circle wall of 61 upper port of ontology, which extends outward to form, contradicts side 62, contradicts side 62 and contacts at mandrel 2
On, contradict side 62 can increase and mandrel 2 between contact area.
Thrust disc 6 in the utility model uses monolithic construction, is assemblied on mandrel 2 using elastic conjunction technique, energy
It enough avoids at higher rotational speeds, the connection bolt looseness of thrust disc, axial motion or resonance occurs.Using whole thrust disc,
Part is reduced, it is easy to process, it can also simplify assembly technology.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The scope of protection of the utility model.
