Abstract
The utility model discloses a high-speed motor is with tilting pad journal bearing, it includes the bearing body, and the characteristic is: the bearing comprises a bearing body and a shaft neck, wherein the bearing body is arranged on the bearing body, the shaft neck is arranged on the bearing body, and the outer side of the bearing is in a large arc shape with the radius of R on an axial plane. And the radius R of a large circular arc of the outer side of the bearing bush on an axial plane is not less than 800 mm. And a gap of 0.06-0.1mm is arranged between the bearing bush and the journal. The utility model has simple, compact and reasonable structure; the tilting pad radial bearing is improved from a common tilting pad radial bearing, and the manufacturing cost is low; the motor can meet the stability requirement of the rotor under high-speed light load, and is particularly suitable for driving a high-speed motor of an air blower.
Description
Technical field
The utility model relates to a kind of used in high-speed motor tilting-pad radial bearing, specifically is used for replacing on the high-speed electric expreess locomotive a kind of tilting-pad radial bearing of magnetic suspension bearing, belongs to the mechanical structure technical field.
Background technique
In present high-speed electric expreess locomotive, use magnetic suspension bearing to come supporting rotor usually.Because structure very complicacy and accuracy of manufacturing is 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 deficiency, thereby a kind of used in high-speed motor tilting-pad radial bearing is provided, and this bearing can satisfy the stability requirement of high speed light loading lower rotor part, is particularly useful for the high-speed electric expreess locomotive of blower.
The technological scheme that provides according to the utility model; Used in high-speed motor tilting-pad radial bearing comprises bearing support, and characteristic is: also comprise bearing shell and axle journal; Said bearing shell is between bearing support and axle journal, and the outside of bearing shell is the great circle arc that radius is R on axial plane.
As further improvement of the present invention, the said bearing shell large circular arc radius R of the outside on axial plane is not less than 800mm.
As further improvement of the present invention, be provided with the gap between said bearing shell and the axle journal, said gap 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; It is improved by general tilting-pad radial bearing and forms low cost of manufacture; Can satisfy the stability requirement of high speed light loading lower rotor part, be particularly useful for the high-speed electric expreess locomotive of blower.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Embodiment
Following the utility model embodiment will combine accompanying drawing to further describe:
As shown in Figure 1: present embodiment comprises bearing support 1, bearing shell 2, rotor journal 3.Said bearing shell 2 is between bearing support 1 and axle journal 3, and the outside of bearing shell 2 is the great circle arc that radius is R on axial plane, and said radius R is not less than 800mm; Be provided with the gap between said bearing shell 2 and the axle journal 3, said gap is 0.06-0.1mm.
When rotor journal 3 rotates; Bearing shell 2 can compensate rotor journal in axial inclination through the swing of circular arc R in axial plane in the outside; Make oil film wedge thickness remain at state comparatively uniformly in axial distribution, simultaneously, because bearing shell 2 is less with the gap of axle journal 3; Reduce the radial vibration of rotor journal 3 relatively, improved the working stability of rotor.
Prove that through repetition test when the utility model was used to drive the high-speed electric expreess locomotive of high-speed centrifugal fan, the working stability of rotor can meet design requirement fully.
