Size, it is located in axis hole, has through hole on ringfeder, and the profile for the core that rises and the shape of through holes of ringfeder match, and it, which can be filled in, rises
Ringfeder is set tightly to withstand on shaft hole inner wall in the through hole of set, the locking member core that will can rise is fixed on the shaft end of head spindle.Locking
Part can limit core axial movement of rising.
When rotor assembles, first head to be placed vertically, rotor upward, is first cold-pressed into head spindle by head spindle termination,
By the cold pressing of head spindle step in place；Ringfeder is put into rotor inner hole (gap cooperation) again, the outer face of ringfeder and rotor
End face, the core plug that then will rise enter ringfeder, are finally threadedly coupled with clamping screw through the core that rises with head spindle.
In the fastening structure of above-mentioned integral machine rotor, the through hole of described ringfeder is in truncated cone-shaped, the corresponding core that rises
In truncated cone-shaped.The small one end of the clear size of opening of ringfeder is towards head spindle.
In the fastening structure of above-mentioned integral machine rotor, the gradient of the through hole of described ringfeder is 6 °.
In the fastening structure of above-mentioned integral machine rotor, the gradient of the described core that rises is 6 °.
In the fastening structure of above-mentioned integral machine rotor, breathing breach is provided with described ringfeder.
In the fastening structure of above-mentioned integral machine rotor, described locking member is clamping screw, described clamping screw
Horizontal through rising, core is threadedly coupled with head spindle.Rise core, ringfeder, head spindle and clamping screw axis in same straight line
On.
It is described to rise by core and ringfeder is prepared by steel material in the fastening structure of above-mentioned integral machine rotor.
Compared with prior art, the utility model is provided with rise core, ringfeder and clamping screw, passes through the core that rises, the cone of ringfeder
Degree coordinates, and they are difficult to loosen once fastening, and sets the core that rises, ringfeder and causes most of power to disperse to be applied to the footpath of rotor
Upwards, the fatigue strength of bolt is substantially reduced, so as to improve complete machine stability and reliability.

Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in figs 1 to 6, the fastening structure of a kind of integral machine rotor provided by the utility model, including locking member, rise
Core 1 and ringfeder 2.
Rotor 6 includes body and the axis hole being arranged on body, rotor 6 are assemblied on head spindle 3, and the size of ringfeder 2 is small
In the axis hole size of rotor 6, it is located in axis hole (gap cooperation), has through hole on ringfeder 2, profile and the ringfeder 2 of the core 1 that rises
Shape of through holes matches, and it, which can be filled in the through hole of ringfeder 2, makes ringfeder 2 tightly withstand on shaft hole inner wall, and locking member will can rise core 1
