There are the runnabilities such as mechanical seal pipe control leakage, pump is separated with motor, medium does not enter motor, motor lubrication impregnable excellent
Point.However, fastidious shaft sealing leakage is all unavoidable again, then there is canned motor pump, canned motor pump gets rid of axle envelope, allows medium
Motor is flowed into, but is closed the stator of motor and rotor with housing made of non magnetic corrosion-resistant metal materials, with
Avoid the runnability of medium influence motor.
Current heavy pump configuration, including the electric machine assembly, flywheel assembly and pump assembly being successively sequentially connected, electronic building brick
Including motor casing, stator, rotor and motor shaft, rotor is linked together with motor shaft.In the prior art, motor shaft both ends only with
Conventional bearing support mode, because vibration, abrasion, thermal expansion etc. influence, will lead to motor shaft and fill after using of long duration
With deviation or bias, to seriously affect the service life of motor.
Utility model content
In view of this, the purpose of the utility model is to provide a kind of roller bearings formulas with deviation automatic compensation structure
Motor rotor construction, to improve the service life of motor.
The utility model is solved the above problems by following technological means: a kind of axis of rolling with deviation automatic compensation structure
Hold brace type motor rotor construction, including motor shaft and rotor, the upper and lower side of the motor shaft be respectively arranged with top chock and
Step, the upper end of motor shaft are provided with short axle, and the upper short axle is rotatablely connected by rolling bearing and top chock, on
Short axle is provided with certainly by being socketed at the top of upper joint sleeve and motor shaft between upper joint sleeve inner wall and motor shaft top exterior walls
Centering spline structure；The lower end of motor shaft is provided with lower short axle, and the lower short axle is connected by rolling bearing and step rotation
It connects, lower short axle is socketed by lower joint sleeve and motor shaft bottom, is arranged between lower joint sleeve inner wall and motor shaft bottom outer wall
Self-centering spline structure and aligning thrust support under having.
Further, buffer is provided in the aligning thrust support.
Further, the upper short axle and upper joint sleeve are integrally formed.
Further, the lower short axle and lower joint sleeve are integrally formed.
Further, the upper self-centering spline structure self-centering spline structure under is involute profile spline structure.
The utility model has the beneficial effects that the roller bearings formula motor with deviation automatic compensation structure of the application turns
Minor structure, including motor shaft and rotor, the upper and lower side of the motor shaft are respectively arranged with top chock and step, motor shaft
Upper end be provided with short axle, the upper short axle is rotatablely connected by rolling bearing and top chock, and upper short axle passes through upper connection
Set is socketed at the top of motor shaft, and upper self-centering spline structure is provided between upper joint sleeve inner wall and motor shaft top exterior walls；
The lower end of motor shaft is provided with lower short axle, and the lower short axle is rotatablely connected by rolling bearing and step, and lower short axle passes through
Lower joint sleeve and motor shaft bottom are socketed, self-centering spline under being provided between lower joint sleeve inner wall and motor shaft bottom outer wall
Structure and aligning thrust support.It, can self-centering, automatic compensating coaxial degree error and axis using the motor rotor construction of the structure
Amount of deflection, moreover it is possible to the adaptive axial stretching travelling with thermal deformation substantially increases the service life of motor.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail below with reference to attached drawing.
As shown in Figure 1, the utility model discloses a kind of roller bearings formula motor with deviation automatic compensation structure
Rotor structure, including motor shaft 1 and rotor 2, the upper and lower side of the motor shaft are respectively arranged with top chock 3 and step 4,
The upper end of motor shaft is provided with short axle 5, and the upper short axle is rotatablely connected by rolling bearing and top chock, and upper short axle passes through
It is socketed at the top of upper joint sleeve 7 and motor shaft, upper short axle and upper joint sleeve are integrally formed, at the top of upper joint sleeve inner wall and motor shaft
Self-centering spline structure 8 is provided between outer wall；The lower end of motor shaft is provided with lower short axle 9, and the lower short axle passes through rolling
Bearing 6 and step are rotatablely connected, and lower short axle is socketed by lower joint sleeve 10 and motor shaft bottom, lower short axle and lower joint sleeve
It is integrally formed, self-centering spline structure 11 and aligning thrust under being provided between lower joint sleeve inner wall and motor shaft bottom outer wall
Support 12, the upper self-centering spline structure self-centering spline structure under is involute profile spline structure, the aligning
Buffer 13 is provided in thrust support, buffer can be butterfly spring.Using the motor rotor construction of the application, a side
Face is connected by spline structure, can be generated radial force using flank of tooth when its carrying, can be played self-centering action；On the other hand, lead to
Aligning thrust support energy adjust automatically gradient is crossed, so as to the amount of deflection of compensating coaxial degree error and axis.Furthermore it is slow by being arranged
