Description
Technical field
The present invention relates to machinery fields, are a kind of and keyway blind-mate Macintosh more specifically.
Background technique
Existing key is usually an one integral piece, and axis and parts on shaft spline respectively, then using a key to two keys
The axial restraint of slot is to realize transmitting torque.There is following defects for discovery in prolonged use verifying for this design:
1, this design requires the accuracy class of key and two keyways very high, not can guarantee the essence of key and keyway in production
Exactness, the error being easy to appear in size.
2, when axis rotates, key can hit even two keyways, in long-time use process, key and keyway
There is certain abrasion, fit clearance is increasing between key and keyway, causes the loosening and abrasion of part, and give using effect
Bring many adverse effects.
Summary of the invention
Since the prior art is there are the above problem, the present invention proposes a kind of and keyway blind-mate Macintosh, mesh
Be the problems such as preventing the error in use process in the accuracy of the loosening and abrasion of part and key and keyway.
The present invention solves the above problems by the following technical programs:
A kind of and keyway blind-mate Macintosh, the Macintosh are set in the keyway of an axis and by a bolts and outside
Connector combines, and the Macintosh includes upper key, side switch and down key；
The upper key includes bearing surface, upper left side face on one, right tilted surface on lower plane and one, and the upper bearing surface abuts
The lower end of the bolt；The upper left side face is abutted against with the outer connector；
The side switch include the first skew back face, second side inclined-plane and side right side, first skew back face and it is described on
Right tilted surface abuts against；The side right side and the keyway side wall of the outer connector and the axis abut against；
The down key includes upper plane, lower left side and once right tilted surface, the upper plane and the lower of the upper key are put down
Face connects；The lower left side and the keyway side wall of the axis abut against, and the lower right tilted surface offsets with second side inclined-plane
It connects.
It is preferred that the first skew back face of the side switch and second side inclined-plane are outwardly convex ipsilateral on the side switch
Two inclined-planes, and first skew back face is located at the top on second side inclined-plane；The corresponding upper right tilted surface is end
The inclined-plane being recessed into it；The corresponding lower right tilted surface is the inclined-plane that starting point is inwardly recessed.
It is preferred that the outer connector is equipped with bolt hole and outside keyway, upper abutting described in the bolt hole face
Face.
Due to using above-mentioned technological means, the application improves the structure of key and keyway, is realized by three separated keys
The comprehensive tight fit of key and axis and outer connector avoids the sliding easily occurred between key and keyway in use
Shock and the loosening of part and the abrasion bad using effect of bring.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the invention with an embodiment of the Macintosh of keyway blind-mate.
Fig. 2 is the explosive view of the invention with the Macintosh of keyway blind-mate.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Referring to shown in Fig. 1 and Fig. 2, Fig. 1 is of the invention with an embodiment of the Macintosh of keyway blind-mate
Cross-sectional view.Fig. 2 is the stereoscopic schematic diagram of the invention with each key of the Macintosh of keyway blind-mate.In this embodiment
The Macintosh with keyway blind-mate, which is set in the keyway 21 of an axis 2 and by a bolt 4 and outer connection
Part 3 combines.The Macintosh 1 includes upper key 11, side switch 12 and down key 13, and specific structure refers to described below.
The upper key 11 includes bearing surface 111, upper left side face 112 on one, right tilted surface 114 on lower plane 113 and one, institute
State the lower end that bearing surface 111 abuts the bolt 4；The upper left side face 112 is abutted against with the outer connector 3.
The side switch 12 includes the first skew back face 121, second side inclined-plane 122 and side right side 123, first skew back
Face 121 is abutted against with the upper right tilted surface 114；The keyway of the side right side 123 and the outer connector 3 and the axis 2
21 side walls abut against.
The down key 13 includes upper plane 131, lower left side 132 and once right tilted surface 133, the upper plane 131 with
The lower plane 113 of the upper key 11 connects；The lower left side 132 and 21 side wall of keyway of the axis 2 abut against, the lower right
Inclined-plane 133 is abutted against with second side inclined-plane 122.
First skew back face 121 of the side switch 12 and second side inclined-plane 122 are convex ipsilateral on the side switch 12
Two inclined-planes risen, and first skew back face 121 is located at the top on second side inclined-plane 122；It is corresponding described upper right oblique
Face 114 is the inclined-plane that end is recessed into it；The corresponding lower right tilted surface 133 is the inclined-plane that starting point is inwardly recessed.
The outer connector 3 is equipped with bolt hole 31 and outside keyway 32, upper bearing surface described in 31 face of bolt hole
111, so as to bolt can be stable compress the upper bearing surface 111.
When installation, the upper key 11, the side switch 12 and the down key 13 are put into the keyway 21, and load onto institute
Outer connector 3 is stated, then the bolt 4 is screwed into from the bolt hole 31 and is screwed.In the process, the upper right tilted surface 114 is right
First skew back face 121 applies pressure, and the side switch 12 can be subjected to displacement to the right until resisting the keyway 21 on right side
With the side wall of the outside keyway 32.And under the pressure that second side inclined-plane 122 applies position occurs to the left for the down key 13
It moves, until resisting 21 side wall of the keyway in left side.Therefore, the side wall of 32 two sides of the keyway 21 and the outside keyway all with institute
It states key 11, the side switch 12 and the down key 13 to come into full contact with, to achieve the purpose that completely attach to fixed.
This and keyway blind-mate Macintosh of the application can be very good the size of reply axis and outer connector
Error, by being screwed into screwing bolts 4, the downward pressure of bolt 4 can promote entire Macintosh that the state of a kind of " tensioner " is presented, divide
Not by the keyway of outer chain element and axis all " tensioner ".
If after being used for a long time, which has a little abrasion loosening, it is only necessary to from the bolt hole 31 by the bolt 4 again
Secondary be screwed into screws, that is, can reach key and the close-fitting state of keyway, without tearing the axis 2 and the outer connector 3 open.
In conclusion the application improves the structure of key and keyway, by three separated keys realization keys and axis and outside
The comprehensive tight fit of connector avoids the sliding easily occurred between key and keyway in use and hits, Yi Jiling
The loosening and the abrasion bad using effect of bring of part.
Embodiments described above is only illustrative of the invention and is not intended to limit the scope of the invention.Art technology
The equivalent changes and modifications that personnel are the present invention, all should belong to the covering scope of claims appended hereto.
