Description
Technical field：
The utility model is related to a kind of magnetic suspension motor rotor anticollision wear-resistant protection set fixed structure.
Background technology：
In existing magnetcisuspension floating centrifugal motor, because magnetic suspension motor rotor descends rotating speed in 20000r/ in working order
More than min, without friction between rotor and bearing, to ensure the precision and applying working condition of magnetic suspension motor rotor, rotor and protection
There is certain gap between bearing, generalist is using one whole plug processing, and processing cost is higher.When motor breaks down or anxious
Stop, collided between rotor meeting and bearing, cause rotor failure, and can not repair.
Therefore, it is necessory to be improved to solve the deficiency of prior art to prior art.
Utility model content：
The utility model is provided a kind of magnetic suspension motor rotor and prevents to solve the problems, such as above-mentioned prior art
Hit wear-resistant protection set fixed structure.
The technical scheme that the utility model is used has：A kind of magnetic suspension motor rotor anticollision wear-resistant protection covers fixed knot
Structure, including impeller and rotor, the impeller are fixed on the top of rotor, also including upper protective case, upper protection bearing, lower protective case
With lower protection bearing, the upper protective case and lower protective case are sheathed on the upper end two ends of rotor, upper protection bearing and lower guarantor respectively
In shield bearing difference tricks on protective case and lower protective case；
One end of the lower protective case stretches out and forms the extension of platform-like, and the bottom of rotor is provided with stage portion,
The extension of lower protective case is connected in the stage portion.
Further, be fixedly connected with nut by screw rod between the impeller and rotor, screw rod through impeller and with turn
Son is fixedly connected, and nut thread is connected to the top of screw rod and impeller is anchored on rotor；Circle is provided with the bottom of impeller
Groove, the circular trough is sheathed on protective case.
The utility model has the advantages that：The utility model simple structure, due to upper and lower protective case anticollision, resistance to
Mill better performances, preferably protect rotor；Upper and lower protective case is mounted with, failure is appeared in motor, it is to avoid direct shock
Rotor, the protective case of damage is disassembled, install new protective case, it is to avoid the single use of original rotor, is dropped significantly
Low cost, extends the service life of rotor.
Brief description of the drawings：
Fig. 1 is the utility model structure chart.
Fig. 2 is lower structure chart of the protective case on rotor in the utility model.
Specific embodiment：
The utility model is further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the utility model discloses a kind of magnetic suspension motor rotor anticollision wear-resistant protection set fixed knot
Structure, including impeller 1, rotor 2, upper protective case 3, upper protection bearing 4, lower protective case 5 and lower protection bearing 6, impeller 1 are fixed on and turn
The top of son 2, upper protective case 3 and lower protective case 5 are sheathed on the upper end two ends of rotor 2, upper protection bearing 4 and lower protection axle respectively
Hold in 6 difference tricks on protective case 3 and lower protective case 5.
One end of lower protective case 5 stretches out and forms the extension 51 of platform-like, and the bottom of rotor 2 is provided with stage portion
21, the extension 51 of lower protective case 5 is connected in the stage portion 21.
It is fixedly connected with nut 11 by screw rod 10 between impeller 1 and rotor 2 in the utility model, screw rod 10 passes through leaf
Wheel 1 is simultaneously fixedly connected with rotor 2, and nut 11 is threaded in the top of screw rod 10 and impeller 1 is anchored on rotor 2.
Circular trough is provided with the bottom of impeller 1, the circular trough is sheathed on protective case 3.
The utility model simple structure, preferably protects rotor due to upper and lower protective case anticollision, anti-wear performance preferably；
Upper and lower protective case is mounted with, failure is appeared in motor, it is to avoid direct shock rotor, the protective case of damage is disassembled,
New protective case is installed, it is to avoid the single use of original rotor, greatly reduces cost, extend the use longevity of rotor
Life.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, some improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as
Protection domain of the present utility model.
