Other feature and advantage of the present utility model will give in detailed description of the invention part subsequently in detail
Explanation.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.It is to be understood that
It is that detailed description of the invention described herein is merely to illustrate and explains this utility model, is not used to limit
This utility model processed.
As shown in Figures 1 to 6, according to an aspect of the present utility model, it is provided that a kind of Axile connection structure,
Including the first axle 1 and the second axle 2 being coaxially disposed, the end of the first axle 1 is provided with the first flange 4,
The end of the second axle 2 is provided with the second flange 5, and the first flange 4 and the second flange 5 are by bolt 6 even
Connect, wherein, the end face of the first axle 1 is formed boss 11, the end face of the second axle 2 is formed with groove
21, boss 11 and groove 21 cooperatively form torque transmission structure.
In Axile connection structure of the present utility model, owing to the composition surface of the first axle 1 and the second axle 2 is formed
Concave-convex fit structure, therefore can completely or at least partially utilize this male-female engagement when two axles rotate
Structure transmits moment of torsion, thus reduces the moment of torsion that Flange joint is transmitted, and reduces the shearing that bolt 6 is subject to
Power, improves the reliability of moment of torsion transmission.In other words, in this utility model, utilize male-female engagement to tie
Structure transmits moment of torsion so that Flange joint only need to provide axial force to ensure the first axle 1 and the second axle 2 not
Separate, dramatically reduce the load of Flange joint.
In order to reduce the moment of torsion that Flange joint bears further, in other words, in order to make Flange joint be not subject to
Moment of torsion, it is preferable that the first flange 4 is loose flange (that is, loose flange), and the second flange 5 is solid
Determine flange.Wherein, the first axle 1 is formed with axial limiting chuck 12, with limit the first flange 4 towards
Second flange 5 moves, i.e. limits the first flange 4 and disengages from the first axle 1.In this case,
Moment of torsion transmission between first axle 1 and the second axle 2 is undertaken by above-mentioned concave-convex fit structure completely, and flange
Connect and only axial force need to be provided to ensure that the first axle 1 and the second axle 2 do not separate.
In Axile connection structure of the present utility model, in order to ensure the first axle 1 and axiality of the second axle 2,
The first flange 4 preferably as loose flange coordinates with the first axle 1 and the second axle 2 circumference simultaneously,
In other words, the first flange 4 is socketed end and the end of the second axle 2 of the first axle 1 simultaneously.Due to
One flange 4 coordinates with the first axle 1 and the second axle 2 circumference simultaneously, therefore can ensure that the first axle 1 and the
Two axles 2 are all coaxial with the first flange 4, and then ensure that the first axle 1 and axiality of the second axle 2.
Axile connection structure of the present utility model can apply to various suitable occasion with realize two axles it
Between moment of torsion transmission.Transmit reliable feature owing to it possesses moment of torsion, be thus used on syllogic shaft
Especially advantageous.Specifically, the first axle 1 and the second axle 2 can be any two phase of syllogic shaft
Adjacent shaft part.In this case, for convenience two axles are taken apart, it is preferable that groove 21 is formed as
Allow groove or half groove of boss 11 abjection.
Boss 11 and groove 21 can have various suitable shape or structure, as long as its side can be passed through
Face coordinates to transmit moment of torsion.As a kind of embodiment, as in figure 2 it is shown, boss 11 is formed as
Along the kidney-shaped boss radially extended of the first axle 1, the length of this kidney-shaped boss is straight with the end face of the first axle 1
Footpath is equal;Groove 21 is formed as the groove radially extended along the second axle 2.In this embodiment,
Two sidewalls of boss 11 match to transmit moment of torsion with two sidewalls of groove 21, and boss 11 is permissible
Bearing of trend along groove 21 moves to deviate from from groove 21.
As another embodiment, as shown in Fig. 1, Fig. 3 to Fig. 5, boss 11 is for being formed at first
Semicircle boss on axle 1, the diameter of this semicircle boss and the equal diameters of the end face of the first axle 1;
Groove 21 is semi-circular recesses, the diameter of this semi-circular recesses and the equal diameters of the end face of the second axle 2.
In this embodiment, the flat sidewall of boss 11 matches with the flat sidewall of groove 21 with transmission
Moment of torsion, boss 11 can move to depart from groove 21 towards multiple directions.
In order to avoid the first flange 4 and the second flange 5 are by together with concrete binding, it is preferable that such as figure
Shown in 1, the first flange 4 is connected to the second flange 5, and at the first flange 4 and the second flange 5
The first sealing ring 7 it is provided with on composition surface.The first flange 4 be loose flange, the second flange 5 be solid
In the case of determining flange, in order to avoid concrete penetrates into the first flange 4 and the composition surface of the first axle 1, shadow
Ring the motion of the first flange 4, it is preferable that as it is shown in figure 1, connecing at the first flange 4 and the first axle 1
The second sealing ring 8 it is provided with on conjunction face.
First flange 4 can have various suitable structure.As a kind of embodiment, as shown in Figure 6,
First flange 4 includes axially-extending portion 41 and radial extension 42, and axially-extending portion 41 is simultaneously with first
Axle 1 and the second axle 2 circumference coordinate, and radial extension 42 should from the outer circumference surface edge of axially-extending portion 41
Extending radially outwardly of axially-extending portion 41, bolt 6 is through radial extension 42, radial extension 42
With the second flange 5 axially-spaced to form cutting annular groove 9.Due to particular job environment of shaft, make
Obtaining and be often stained with concrete on bolt 6, this causes needing to cut off bolt 6 when dismantling flange, cut ring
Groove 9 be designed to facilitate the cutting of bolt 6.
In the situation that the first flange 4 is the loose flange coordinated with the first axle 1 and the second axle 2 circumference simultaneously
Under, when the second axle 2 is pulled down from the first axle 1 by needs, can be first by the first flange 4 and the second method
Blue 5 take apart, then move axially the first flange 4, make the first flange 4 disengage from the second axle 2, just
Two axles directly can be taken apart, convenient disassembly, time-consuming.
In syllogic shaft of the present utility model, as a kind of embodiment, the first axle 1 is stirring
The middle shaft part of axle, the second axle 2 is left shaft part or the right axis section of shaft.But in view of middle shaft part
On be not easy to installation activity flange, it is therefore preferred that the first axle 1 is the left shaft part of shaft or right axle
Section, the second axle 2 is the middle shaft part of shaft.
According to another further aspect of the present utility model, it is provided that a kind of concrete mixer, this concrete mixer has
Rabbling mechanism as above.
Preferred implementation of the present utility model is described in detail above in association with accompanying drawing, but, this practicality is new
Type is not limited to the detail in above-mentioned embodiment, in technology concept of the present utility model,
The technical solution of the utility model can be carried out multiple simple variant, these simple variant belong to this reality
With novel protection domain.
It is further to note that each the concrete technology described in above-mentioned detailed description of the invention is special
Levy, in the case of reconcilable, can be combined by any suitable means.In order to avoid need not
The repetition wanted, various possible compound modes are illustrated by this utility model the most separately.
Additionally, combination in any can also be carried out between various different embodiment of the present utility model, only
Wanting it without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
