Outside is provided with shell, and the outer rim of the shell is fixedly linked by hex bolts and centre circle.
The first clamp spring is equipped with the output shaft on the outside of output shaft hole, the empty inner side of the shell is rolled positioned at first
The second clamp spring is equipped with above bearing.
On the inside of the outer ring fastener the 3rd clamp spring is equipped with positioned at the second rolling bearing lower end.
The deviation distance e of the eccentric wheel is 0.5-0.8mm.
The deviation distance e is 0.75mm.
The utility model has the advantages that：
1st, this coupler structure is compact, by adjusting its structure design, can realize gear ratio in the same direction and different, transmission
It is efficient, there is stronger bearing capacity and impact resistance, compact-sized transmission moment of torsion is big, has buffering to a certain extent
The effect of damping.Its gearratio is to be determined by intermeshing cylindrical roller number with the cycloid number of teeth, its drive characteristic and circle
There is specific relation between column roller, the cycloid tooth number of teeth and eccentric wheel three, otherwise just can not correctly transmit movement.
2nd, this shaft coupling can realize gear, output shaft and input shaft counter motion, i.e., become by the utility model
The connection of fast coaxial shaft coupling is, it can be achieved that speedup, constant speed and underdrive.

Embodiment
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
Embodiment 1：
Such as Fig. 1-2, a kind of reversely gear shaft coupling, it includes input shaft 15, and the is set with the input shaft 15
Two rolling bearings 12, the outer cover of second rolling bearing 12 are equipped with centre circle 1；The centre circle 1 is equipped with cylindrical roller 9, institute
State the outside of centre circle 1 and be equipped with cycloid tooth 10；The cycloid tooth 10 is arranged in outer ring fastener 8, and by lock-screw 11 by two
Person fixes；Eccentric wheel 7 is internally provided with centre circle 1, the eccentric wheel 7 is installed on input shaft 15；The outer ring fastener 8 is pacified
On output shaft 6；First rolling bearing 3 is installed on the output shaft 6, is provided with the outside of the first rolling bearing 3 outer
Shell 2, the outer rim of the shell 2 are fixedly linked by hex bolts 13 and centre circle 1.
Further, the first clamp spring 5, the empty inner side of the shell 2 are equipped with the output shaft 6 on the outside of output shaft hole
The second clamp spring 4 is equipped with above the first rolling bearing 3.It can be rolled by first clamp spring 5 and the second clamp spring 4 to first
The Internal and external cycle of dynamic bearing 3 carries out effective spacing.
Further, the inner side of outer ring fastener 8 is equipped with the 3rd clamp spring 14 positioned at 12 lower end of the second rolling bearing.Pass through
3rd clamp spring 14 can carry out the inner ring of the second rolling bearing 12 spacing.
Further, deviation distance e is equipped between the axial line of the input shaft 15 and output shaft 6.
Further, the deviation distance e of the eccentric wheel 7 is 0.5-0.8mm.
Further, the deviation distance e is 0.75mm.
The course of work and operation principle of the utility model be：
Its transmission principle is：Centre circle 1 and shell 2 are fixed with hex bolts 13, so that mounted in a fixed number on centre circle
The circumferential movement of the cylindrical roller of amount is limited.When main motion is passed to the input of middle eccentric wheel from input shaft and rotated, due to bias
Effect so that by cylindrical roller promote move out, at this time again limited since cylindrical roller is circumferentially rotated by centre circle, then justify
Column roller only extrudes cycloid gear ring and circumferentially produces a circumferential movement, could release the interference that this radial motion is obstructed,
So allowing for cycloid tooth has circular motion, so as to drive outer ring fastener that circular motion is passed to output shaft.When middle inclined
When heart wheel shaft rotates one week, eccentric wheel promotes a cylindrical roller on centre circle, while cycloid of the cylindrical roller extruding with a tooth
Gear ring causes it accordingly to circumferentially rotate a between cog angle, while causes the rotation direction of cycloid tooth with inputting rotational axis direction phase
Instead, this is that speed and direction changing movement is transmitted.The shaft coupling has simple in structure, and easy to operate, operating is reliable, it is possible to achieve a variety of
The movement of gearratio, and can counter motion, can effectively realize the effect of transmission.
It is i that cylindrical roller, which fixes its gearratio, and inputs and belong to coaxial counter motion transmission with output.As shown in Figs. 1-2,
After fixed cylinder roller revolution motion, when middle camshaft rotates one week, eccentric wheel promotes a cylindrical roller on centre circle,
And each cylindrical roller can then extrude cycloid gear ring so that the cycloid tooth with each and every one tooth accordingly circumferentially rotates a tooth, and every
Accordingly a corresponding tooth asks angle to a tooth, and, i other words middle camshaft rotated 1 week, eccentric wheel promotes on fixed centre circle at the same time for this
A cylindrical roller in face, so that cycloid gear ring correspondingly rotates an angle between teeth, due to having a tooth on cycloid tooth, thus just
Form the gearratio of i.Its contact condition with cycloid gear ring is when that middle eccentric wheel by shown by arrow direction turns to its is maximum
Cylindrical roller is promoted during eccentric position, cylindrical roller extruding cycloid tooth is rotated, is not difficult to find out, cycloid gear ring can be anti-to diagram at this time
Direction both rotated in an anti-clockwise direction.
By above-mentioned description, those skilled in the art completely can be without departing from this item utility model technological thought
In the range of, various changes and amendments are carried out all within the scope of protection of the utility model.The utility model is not use up
Matters, belong to the common knowledge of those skilled in the art.
