The feature of " second " can be expressed or implicitly include at least one this feature.In addition, the technical side between each embodiment
Case can be combined with each other, but must be capable of by those of ordinary skill in the art based on, when the combination of technical scheme
Will be understood that the combination of this technical scheme does not exist when appearance is conflicting or cannot realize, also do not require in this utility model
Protection domain within.
Referring to Fig. 1, double cantilever blade wheel rotor balance joints that this utility model provides, including pull bar 1, spacer shell 2,
Union joint 3 and locking nut 6.Wherein, pull bar 1 is screwed onto in rotor tooth wheel shaft 4 through impeller of rotor 5, union joint 3 and spacer shell
2 connections, spacer shell 2 is connected with the impeller of rotor 5 being fixedly connected on gear shaft 4 end.
Referring to Fig. 2, the middle part of spacer shell 2 is provided with can make spacer shell 2 be enclosed within the unthreaded hole 21 on pull bar 1, the light of spacer shell 2
It is provided with the first screwed hole 22 around hole.
Referring to Fig. 3, it is also equipped with the middle part of union joint 3 making union joint 3 be enclosed within the through hole 31 on pull bar 1, union joint 3 and mistake
The sides crossing set 2 connection are provided with the second screwed hole 32 that, position equal with the first screwed hole 22 number be corresponding and aperture is mated,
The opposite side of union joint 3 is provided with the 3rd screwed hole 33 for connecting dynamic balancing machine.Union joint 3 connects the side of spacer shell 2
Middle part is additionally provided with the containing cavity 34 for accommodating locking nut 6.
Spacer shell 2 is enclosed within pull bar 1 by unthreaded hole 21, and locking nut 6 is screwed onto on pull bar 1, due to locking nut 6 outward
Footpath is more than the diameter of the unthreaded hole 21 at spacer shell 2 middle part, therefore can withstand spacer shell 2 by screwing tight locking nut 6, by spacer shell
2 are tightly extruded with impeller of rotor 5 and fit together.Union joint 3 is enclosed within pull bar 1 by through hole 31, passes through first with bolt
