Abstract
The utility model discloses a radial bearing with a tiltable bush for a high-speed motor, which comprises a bearing body. Radial bearing with the titable bush for the high-speed motor is characterized by further comprising a bearing bush and a bearing neck, wherein the bearing bush is positioned between the bearing body and the bearing neck, the outside of the bearing bush has a large arch shape with the radius being R on an axial plane; the radius R of the large arc shape of the outside of the bearing bush on the axial plane is not less than 800mm; and the a clearance within 0.06-0.1mm is arranged between the bearing bush and the bearing neck. The radial bearing is simple, compact and reasonable in structure, is modified from a common radial bearing with the tiltable bush, low in manufacturing cost, capable of meeting the requirement of stability of a rotor with high speed and light load, and is especially suitable for the high-speed motor for driving a 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.
