Abstract
The invention discloses a supporting structure for a high speed motor rotor. The supporting structure comprises a rotor body, and is characterized by further comprising bearing bodies and bearing pads, wherein the bearing pads are arranged in the bearing bodies to form tilting-pad bearing body structures; the left and right tilting-pad bearing body structures are arranged and supported at first and second journals of the rotor; a gap between the bearing pad and the first journal is 0.06 to 0.1mm; and the gap between the bearing pad and the second journal is 0.06 to 0.1mm. The supporting structure has a simple, compact and rational structure and low manufacturing cost, can meet requirements on the working stability of the rotor in high speed and light load occasions, and is particularly suitable for driving a high speed centrifugal blower.
Description
Technical field
The present invention relates to a kind of supporting structure of high speed rotor of motor, specifically be used for replacing on the high-speed electric expreess locomotive form of a kind of supporting rotor of magnetic suspension bearing, belong 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 objective of the invention is to overcome above-mentioned weak point, thereby a kind of supporting structure of high speed rotor of motor is provided, can satisfy the job stability of rotor, be particularly suitable for the occasion of high speed light loading in the high speed light loading occasion.
According to technical scheme provided by the invention, a kind of supporting structure of high speed rotor of motor, comprise rotor block, feature is: also comprise bearing body and bearing shell, be provided with bearing shell in the described 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 a further improvement on the present invention, the gap of the described bearing shell and first axle journal is between 0.06-0.1mm.
As a further improvement on the present invention, the gap of the described bearing shell and second axle journal is between 0.06-0.1mm.
Compared with the prior art the present invention has the following advantages:
The present invention 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 a schematic diagram of the present invention.
Embodiment
Following the present invention will be further described in conjunction with the accompanying drawings:
As shown in Figure 1: the present invention includes rotor 1, bearing body 2, bearing shell 3.Be provided with bearing shell 3 in the described 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 described bearing shell 3 and the first axle journal 1-1 is between 0.06-0.1mm.The gap of the described 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 manufacturing of the present invention is used to drive the high speed centrifugation air blast, the job stability of rotor can meet design requirement fully.
