Abstract
A kind of three bearing arrangements of disc type electric machine, including cover plate, base, described base center inner wall is sequentially installed with ball bearing, angular contact bearing, plain thrust bearing, and wherein ball bearing constitutes motor radial support point with angular contact bearing, and plain thrust bearing is the axial strong point of electric machine rotor；The end face both ends of the surface flush respectively with base of the ball bearing, plain thrust bearing；Described has cover plate in the base upper cover positioned at ball bearing end；Beneficial effects of the present invention are：The structure meets the force request of disc type electric machine, and compact conformation.
Description
Technical field
The present invention relates to a kind of three bearing arrangements of disc type electric machine.
Background technology
Bearing arrangement in existing disc type electric machine is unreasonable due to designing, and causes the discontinuity of motor, so that
The performance of motor is not good, and service life is shortened.
The content of the invention
It is an object of the invention to overcome the shortcomings of that prior art is present, and provide a kind of three bearing knots of disc type electric machine
Structure.
The purpose of the present invention is completed by following technical solution, including cover plate, base, in described base center
Wall is sequentially installed with ball bearing, angular contact bearing, plain thrust bearing, and wherein ball bearing constitutes motor radially with angular contact bearing
The strong point, plain thrust bearing is the axial strong point of electric machine rotor；The ball bearing, plain thrust bearing end face respectively with
The both ends of the surface flush of base.
Preferably, the base upper cover positioned at ball bearing end has cover plate.
Beneficial effects of the present invention are：The structure meets the force request of disc type electric machine, and compact conformation.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Label in accompanying drawing is respectively：1st, cover plate；2nd, ball bearing；3rd, base；4th, angular contact bearing；5th, plane is pushed away
Power bearing.
Embodiment
Detailed introduction is done to the present invention below in conjunction with accompanying drawing：As shown in Figure 1, the present invention includes cover plate 1, base 3,
The described center inner wall of base 3 is sequentially installed with ball bearing 2, angular contact bearing 4, plain thrust bearing 5, wherein ball bearing 2 with
Angular contact bearing 4 constitutes motor radial support point, and plain thrust bearing 5 is the axial strong point of electric machine rotor；The ball bearing
2nd, the both ends of the surface flush of the end face of plain thrust bearing 5 respectively with base 3.It is described on the base 3 positioned at the end of ball bearing 2
It is stamped cover plate 1.
Ball bearing 2 constitutes motor radial support point with angular contact bearing 4, and angular contact bearing 4 can also bear the axle of axle stretch end
To thrust；Plain thrust bearing 5 is primarily subjected to axial direction electric machine rotor electromagnet pull, coordinates with axle with gap is combined into；The knot
Structure meets the force request of disc type electric machine, and compact conformation.
The present invention is not limited to the above-described embodiments, and any change is made no matter being constituted in its shape or material, every to adopt
Structure design provided by the present invention is used, is all a kind of deformation of the present invention, is considered as within the scope of the present invention.
