Embodiment
As Figure 1-3, a kind of double rolling key clutch of the present invention, including inner ring 1 and outer shroud 6, inner ring 1 and outer shroud 6 it
Between be provided with both and be capable of the activity space of relative motion, is provided with roller rolling retainer 3 in activity space, roller rolling retainer 3 is arranged on
On retainer orchid disk 5, the end of inner ring 1 is provided with inner ring orchid disk 1, and inner ring orchid disk 1 is connected with retainer orchid disk 5, roller rolling retainer 3
On be uniformly provided with mounting hole around its center of circle, be placed with roller 7 in mounting hole, the outside of inner ring 1 is uniformly surrounded with along its circle
The projection that week is set, the outside of connecting line between adjacent projections and inner ring 1 is tangent to form the first plane, and the top of projection is provided with
Second plane, the external diameter of roller rolling retainer 3 is identical with the external diameter of outer shroud 6, and the outside of roller rolling retainer 3 is convex provided with stretching out
Go out portion 301.
Also include block piece 8, block piece 8 is located at the side of protuberance 301, and the end of protuberance 301 is plane, and block piece 8 includes
Mounting bracket 802 and the regulating bolt 801 being fixed thereon, regulating bolt 801 are axially or radially arranged on mounting bracket 802, gear
The placement of the position of part 8 will ensure protuberance 301 when turning to the position corresponding with regulating bolt 801, and regulating bolt 801 rises
To can both stop protuberance 301 effect and can ensure protuberance 301 can pass through, so as to regulating bolt 801 with it is convex
The plane for going out portion 301 is frictional contact conditions.
Preferably, extension spring 4 is provided between inner ring orchid disk 1 and retainer orchid disk 5, extension spring 4 has the function that to reset, and makes inner ring
The projection in 1 outside separates with roller 7, outer shroud 6 is separated with inner ring 1, has relative activity space between the two, so that outer shroud
6 realize and can surmount rotation relative to inner ring 1 is equidirectional.
Preferably, projection is identical with the number of roller 7, and the diameter of roller 7 is more than the diameter of mounting hole, roller 7 with it is adjacent
The midpoint CONTACT WITH FRICTION of connecting line between projection, the minimum point of the inner side of roller rolling retainer 3 contacts with the second planar friction, in guarantee
Ring 1 makes roller 7 and roller rolling retainer 3 remain relative in the presence of frictional force with inner ring 1 when being rotated as drive end
Static state, roller 7 and the synchronous axial system of roller rolling retainer 3 can be driven, so as to drive the protuberance 301 rolled on retainer
Rotate when with the CONTACT WITH FRICTION of regulating bolt 801.
Based on said structure, concrete operating principle of the present invention is：Inner ring 1 is drive end, and outer shroud 6 is driven end, due to this
The structure of invention inactive state is between the projection in the outside of inner ring 1 and the inner side of roller rolling retainer 3, between the plane of roller 7 and first
It is CONTACT WITH FRICTION, in relative static conditions, therefore can drives roller rolling retainer 3 is synchronous to turn while drive end rotates
Dynamic, now, outer shroud 6 and inner ring 1 as driven end are separate state, and outer shroud 6 can do equidirectional super relative to inner ring 1
More rotate, with the synchronous axial system of drive end and roller rolling retainer 3, protuberance 301 on roller rolling retainer 3 also concomitant rotation,
When protuberance 301 and 8 CONTACT WITH FRICTION of block piece, stop of the regulated bolt 801 of roller rolling retainer 3 to it, roller rolling retainer 3
Rotating speed it is slack-off, speed discrepancy be present between inner ring 1, the projection in the outside of inner ring 1 is gone to the position contacted with roller 7, now,
Roller rolling retainer 3 is jacked up to be engaged with outer shroud 6, so as to which outer shroud 6 engages with inner ring 1, makes realization between outer shroud 6 and inner ring 1 synchronous
Rotate, when protuberance 301 departs from block piece 8, due to being provided with extension spring 4 between inner ring orchid disk 1 and retainer orchid disk 5, utilize extension spring 4
Roller rolling retainer 3 is kept in the center in reset, both separate states is returned between outer shroud 6 and inner ring 1, outer shroud 6 can phase
Surmount rotation for inner ring 1 is equidirectional；When drive end stops operating, driven end both direction can turn clockwise and anticlockwise
It is dynamic, realize that twocouese freely rotates.
The present invention it is compact-sized, have a wide range of application, vibrating noise it is small.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, technical side of the those of ordinary skill in the art to the present invention
The various modifications and improvement that case is made, it all should fall into the protection domain of claims of the present invention determination.
