Abstract
The utility model discloses a support structure of a high-speed motor rotor, which comprises a rotor body and is characterized by comprising bearing bodies and bushings. The bushings are arranged in the bearing bodies so as to form tilting pad bearing body structures. The left tilting pad bearing body structure and the right tilting pad bearing body structure are respectively supported at a first shaft neck position and a second shaft neck position of the rotor. The gap between the bushing and the first shaft neck ranges between 0.06mm to 0.1mm, and the gap between the bushing and the second shaft neck ranges between 0.06mm to 0.1mm. The support structure of the high-speed motor rotor is simple, compact and reasonable in structure, low in fabrication cost, capable of satisfying work stability of the rotor in a high-speed light load occasion for the reason that the gaps between the bushings and the shaft necks are relatively small and especially suitable for driving a high-speed centrifugal blower.
Description
Technical field
The utility model relates to a kind of supporting structure of high speed rotor of motor, specifically is used for replacing on the high-speed electric expreess locomotive form of a kind of supporting rotor of magnetic suspension bearing, belongs to the mechanical structure technical field.
Background technology
In present high-speed electric expreess locomotive, use magnetic suspension bearing to come supporting rotor, excellent stability usually.Because the structure of magnetic suspension bearing is very complicated, and the accuracy of manufacture is very high, and cost is significantly risen, and has had a strong impact on this type of high-speed electric expreess locomotive promoting the use of in civilian industry.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point, thereby a kind of supporting structure of high speed rotor of motor is provided, and can satisfy the job stability of rotor in the high speed light loading occasion, is particularly suitable for the occasion of high speed light loading.
The technical scheme that provides according to the utility model; A kind of supporting structure of high speed rotor of motor; Comprise rotor block; Characteristic is: also comprise bearing body and bearing shell, be provided with bearing shell in the said bearing body and formed the tilting-pad bearing structure, about two tilting-pad bearing structures respectively mounting support at the second axle journal position of first axle journal and the rotor of rotor.
As further improvement of the present invention, the gap of the said bearing shell and first axle journal is between 0.06-0.1mm.
As further improvement of the present invention, the gap of the said bearing shell and second axle journal is between 0.06-0.1mm.
Compared with present technology the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, low cost of manufacture; Because the gap of bearing shell and axle journal is less, can satisfy the job stability of rotor in the high speed light loading occasion, especially be fit to driving high speed centrifugation air blast.
Description of drawings
Fig. 1 is the utility model sketch map.
Embodiment
Following the utility model will combine accompanying drawing to further describe:
As shown in Figure 1: the utility model comprises rotor 1, bearing body 2, bearing shell 3.Be provided with bearing shell 3 in the said bearing body 2 and formed the tilting-pad bearing structure, about two tilting-pad bearing structures respectively mounting support at the second axle journal 1-2 position of the first axle journal 1-1 and the rotor 1 of rotor 1.The gap of the said bearing shell 3 and the first axle journal 1-1 is between 0.06-0.1mm.The gap of the said bearing shell 3 and the second axle journal 1-2 is between 0.06-0.1mm.
When rotor rotation, because bearing shell 3 is less with the gap of axle journal 1-1 and axle journal 1-2, the stability of oil film wedge better is applicable to the high speed light loading occasion.
When experiment showed, that repeatedly high-speed electric expreess locomotive with the utility model manufacturing is used to drive the high speed centrifugation air blast, the job stability of rotor can meet design requirement fully.
