Specific embodiment
Combine accompanying drawing below by specific embodiment the present invention is described in further detail.The application can be with multiple
Different forms is realizing the embodiment however it is not limited to described by the present embodiment.The purpose of detailed description below is provided
It is easy for present disclosure is become apparent from thorough explanation, the words of the wherein indicating position such as upper and lower, left and right is only pin
For shown structure position in respective figure.
However, those skilled in the art may be aware that one or more of details descriptions can be by
Omit, or can also be using other methods, assembly or material.In some instances, some embodiments are not described
Or be not described later in detail.
Additionally, technical characteristic described herein, technical scheme can also be closed with any in one or more embodiments
Suitable mode combines.For a person skilled in the art it is easy to understand the method relevant with embodiment provided herein
Step or operation order can also change.Therefore, any order in drawings and Examples is merely illustrative purposes, not secretly
Show requirement in a certain order, require unless expressly stated according to a certain order.
Herein for part institute serialization number itself, such as " first ", " second " etc., it is only used for distinguishing described object,
There are no any order or art-recognized meanings.And the application described " connection ", " connection ", if no special instructions, all include direct with
It is indirectly connected with (connection).
Fig. 1, Fig. 2 and Fig. 3 show a specific embodiment of the mechanism of radial force of this transfer shaft of the application, its
Specifically include that matrix 1, impeller-hub 2 and driven shaft 3.Wherein:
Impeller-hub 2 and driven shaft 3 are all axially displaceably connected on matrix 1.Driven shaft 3 is detachably connected with matrix 1,
It can easily carry out changing installs, and in Fig. 1, the upper end of driven shaft 3 and the lower end of impeller-hub 2 are engaged.And,
Driven shaft 3 is arranged in impeller-hub 2 and is promoted between thing p, during practical application, in FIG, applies the power band to impeller-hub 2
Dynamic impeller-hub 2 moves down, the lower end conflict driven shaft 3 of impeller-hub 2 and so that driven shaft is also moved down, thus pass through driven shaft
3 promotions are promoted thing p and are moved along preset direction.
The one big key improvement of the present embodiment is: as shown in figure 3, driven shaft 3 is towards that one end of described impeller-hub 2
End face be sphere, the end face of described impeller-hub 2 that one end towards driven shaft 3 is the plane perpendicular to this impeller-hub axis.
So, during promoting by promotion thing p, the contact surface due to being promoted thing p and driven shaft 3 is not level to driven shaft 3
(irregular contact surface), leads to be promoted thing p that the counteracting force of driven shaft 3 is existed along driven shaft axis direction simultaneously
Axial thrust load fAxiallyWith the radial component f along driven shaft radial directionRadially.Because the top end face of driven shaft 3 in Fig. 3 is ball
Face, and the bottom end face of impeller-hub 2 is the plane perpendicular to impeller-hub axis, the sphere on driven shaft 3 top and impeller-hub 2 bottom
Plane be tangent relation, such driven shaft 3 is to the base plane phase that the counteracting force of impeller-hub 2 is with impeller-hub 2 all the time
Vertical, that is, driven shaft is consistent with the axis direction of impeller-hub to the counteracting force direction of impeller-hub, therefore impeller-hub only receives
Axial force is without by radial force, so substantially prolongs the service life of impeller-hub 2.The footpath being promoted in thing counteracting force
Finally it has been applied to without being applied on impeller-hub 2 on driven shaft 3 and matrix 1 to component, after long-time use, more renewed
Driven shaft 3.
As shown in figure 1, this mechanism is also provided with the return spring 4 for guiding described driven shaft 3 to reset, this return spring
4 concrete mounting means is as follows:
The flange 3a of one circle radially protruding is formed on the axial wall of described driven shaft 3, described return spring 4 be enclosed within described from
Outside moving axis 3, and one end of return spring 4 is resisted against on described flange 3a, and the other end is resisted against in described matrix 1.
So, complete in FIG to being promoted after the pushing down on of thing p, once impeller-hub 2 upward retraction, driven shaft
Retract upwards in the presence of return spring 4.
In the present embodiment, described matrix 1 includes coaxially being set in the outer linear bearing 5 of described driven shaft 3, this linear bearing 5
For guiding the axial movement of described driven shaft 3, can prevent driven shaft 3 from shifting in moving process.Matrix 1 also includes one
The driven axle installing plate of block 6, described linear bearing 5 is directly to be fixedly mounted in this driven axle installing plate 6.
Additionally, for the ease of the manipulation to described impeller-hub 2, the described matrix 1 originally implementing also is included for promoting
State the promotion axial brake device 7 of impeller-hub 2 movement, this promotion axial brake device 7 can adopt Vidacare corp, such as motor；
Fluid pressure drive device can be adopted, such as hydraulic cylinder；Pneumatic actuating device can also be adopted, such as pneumatic cylinder.
Described driven axle installing plate 6 and described promotion axial brake device 7 pass through many spaced support columns 8 of annular admittedly
Surely link together (ingredient that these support columns 8 are also described matrix 1).
Above content is to further describe it is impossible to assert this with reference to specific embodiment is made for the present invention
Bright it is embodied as being confined to these explanations.For general technical staff of the technical field of the invention, do not taking off
On the premise of present inventive concept, some simple deduction or replace can also be made.
