Column 202 is drum shaped body, and it is cylinder to couple 201 main body of sub- ontology, and length is consistent with 3 axial dimension of outer shroud, its underpart both ends edge
One plane of axial each processing simultaneously makes connecting screw hole for being fixedly connected with spring 6；To realize rolling friction pair, in axial direction
Central symmetry establishes annular protrusion, and projection portion total cross-section is silo type, to reduce and the contact friction of the slot both sides of outer shroud 3
Face, projection portion length are slightly less than the annular groove groove width that outer shroud 3 opens up, and sulculus 301 is opened up above the projection portion for pacifying
Roller 202 is filled, small groove depth is less than 202 maximum diameter of roller, it is ensured that convex shape is in when roller 202 is installed in sulculus
State, 301 sleeving and riveting of sulculus closes up after installation.
As shown in fig. 6,3 axial dimension of the outer shroud is equal with sub 2 axial dimensions of coupling, outer diameter and semiaxis device I1 are maximum outer
Diameter is equal, internal diameter is more than II 5 maximum outside diameter of semiaxis device but the annulus of rear maximum gauge is installed less than roller 202, in it
Diameter circumference uniform distribution opens up tooth form straight slot as engaging groove, is axially opened up along internal diameter profile line at center slightly wider compared with roller 202
Annular groove for disposing roller 202, its both ends of the surface open up process threaded hole for using joint bolt 9 by outer shroud 3 with press
Lid 4 is connected and is connect outer shroud 3 with semiaxis device I1 using articulation screw 10.
The gland 4 is that internal diameter is equal with II 5 minimum outer diameter of semiaxis device, and outer diameter is equal with semiaxis device I1 maximum outside diameters, axis
To the disk that size is 3 axial dimension of outer shroud about 1/2, oil seal is opened up in inner radius, is provided with through-hole on disk in an axial direction, used
In outer shroud 3 is connect with gland 4 using joint bolt 9.

When prime mover is static, for coupling son 2 under the action of spring 6, the groove of outer shroud 3 is close in 202 outer surface 402 of roller
Face 102 couples the field of conjugate action 501 that sub- body outer surface 401 is close to outer shroud 3.When prime mover starts to start, coupling 2 is with half
II 5 synchronous rotary of axis device along II 5 slot 601 of semiaxis device toward moving at outer shroud 3, is nibbled under the action of the centrifugal force when being transferred to outer shroud 3
When closing slot, the field of conjugate action 501 that sub- body outer surface 401 is close to outer shroud 3 is coupled, the elastic force and centrifugal force of coupling 2 by spring
Force action, tangential component generate torque, if torque overcomes load torque, coupling 2 just to drive outer shroud 3 and half enough at this time
Axis device I1 synchronous rotaries；If torque is not enough to overcome load torque, couple sub 2 compressed springs 6, along II 5 slot 601 of semiaxis device to
Slot bottom moves, and exits 3 engaging groove of outer shroud, and the grooved surface 102 that outer shroud 3 is close in 202 outer surface 402 of roller skids；With prime mover
Rotating speed continuous improvement, coupling 2 are gradually increased by centrifugal force, when coupling 2 is sufficiently large by centrifugal force, the torque of generation
Overcome load torque, coupling 2 that outer shroud 3 and semiaxis device I1 synchronous rotaries is driven to enter working condition enough.If load torque increases
It is big to predetermined overload torque, the reaction force generated by the field of conjugate action 501 of outer shroud 3 be more than elastic force suffered by coupling 2 and from
The tangential component of the resultant force of mental and physical efforts, coupling 2 just exit 3 field of conjugate action of outer shroud, and the groove of outer shroud 3 is close in 202 outer surface 402 of roller
Face 102 is skidded, until after load torque restores normal, coupling 2 is transferred to meshing state automatically.
The starting safety coupling of the present invention is according to relevant parameters such as primemover system rotating speed, nominal torque, overload magnifications
The matched design of coupling protonatomic mass, the elastic coefficient and initial work location is carried out, it can be achieved that product seriation and special-purpose assorted.
Although combining attached drawing describes embodiments of the present invention, it will be apparent to those skilled in the art that not
Under the premise of being detached from the principle of the invention, various modifications and improvements can be made, these also should be regarded as the protection for belonging to the present invention
