Concrete application process of the present utility model is as follows：
It is as follows that a kind of removable axle sleeve for motor connection impeller is equipped with principle：
With reference to shown in Fig. 4, by two interior hexagonal holding screws in two locking holes 3, as screw is in locking hole 3
Constantly tighten, the threaded function of first semi-circular threaded 111 pushes screw in terminal pad 1 first through hole 12 in locking hole 3
Sharp narrow end.When screw props up the bottom of the second semicircular unthreaded hole 22, tapered sleeve 2 is just transmitted the force to, tapered sleeve 2 is just relative
Moved in terminal pad 1 towards the direction of 12 sharp narrow end of first through hole in terminal pad 1.Because the reason for taper, the just constantly contracting of tapered sleeve 2
Tightly, the axial gap 24 of tapered sleeve 2 closes, and tapered sleeve 1 packs tightly motor shaft 5；And motor shaft 5 reacts on tapered sleeve 2, remake and be used for
Terminal pad 1.So, terminal pad 1, tapered sleeve 2 and motor shaft 5 just closely fit together.
A kind of removable axle sleeve dismounting principle for motor connection impeller is as follows：
With reference to shown in Fig. 6, by interior hexagonal holding screw is dismantled in locking hole 3 on two, then by an interior hexagonal tightening
On screw in removal hole 4, as screw is constantly tightened in removal hole 4, screw is also towards first through hole 12 in terminal pad 1
The direction motion of sharp narrow end, when screw head props up the bottom of the first semicircular unthreaded hole 122, transmits the force to terminal pad 1,
At this moment terminal pad 1 is moved with respect to tapered sleeve 2 to the direction of 1 first through hole, 12 sharp narrow end in terminal pad.So, terminal pad 1 with
Tapered sleeve 2, which is just separated from, to be come, and tapered sleeve 2 is also because lose the restraining force for coming from first through hole 12 in terminal pad 1, tapered sleeve 2
Axial gap 24 recovers, and is also separated from and with motor shaft 5.
From foregoing description as can be seen that the utility model have it is simple in construction, versatile, can Fast Installation with tearing open
Unload, the features such as light weight and service life are long.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is done any formal
Limitation, therefore all contents without departing from technical solutions of the utility model, implement according to the technical essence of the utility model to more than
Any simple modification, equivalent change and modification for being done of example, in the range of still falling within technical solutions of the utility model.
