Telescopic rod movement is driven, telescopic rod will will drive driving wheel rotation, and driving wheel will will drive the movement of planetary gear fixing axle, planetary gear
Fixing axle will will drive planetary gear movement, and the planetary gear of movement will will drive gear ring movement, and gear ring will will drive and be mounted on
Clutch disk movement thereon, the clutch disk of movement are moved will drive output shaft mounted thereto, and output shaft will band
Dynamic load campaign, when the load on output shaft becomes larger suddenly, output shaft at this time will not be selected, so that clutch disk
It will not move, clutch disk will not drive gear ring to move, and input shaft at this time is still rotating, so planetary gear can enclose
Axis around itself rotates, and movement is engaged on gear ring, and planetary gear at this time will will drive the movement of planetary gear fixing axle, fortune
Dynamic planetary gear fixing axle will be by opening to open to obtain screw-internal thread fit on external screw thread and ring set thereon, due to ring set installation
On fast pulley, so that planetary gear fixing axle will be moved in axial direction, the planetary gear fixing axle of movement will make
When driving wheel is removed out of half slot, driving wheel will with the outer circle face contact that does not have open semicircle slot in planetary gear fixing axle, from
And make the outer circle face contact of driving wheel Yu planetary gear fixing axle, it reaches the energy eliminated when driving wheel is removed out of half slot and disappears
Consumption；When the critical torque for needing to adjust torque limiter is, adjusting set is rotated by hand, the adjusting set of rotation will institute on it
Under the action of opening screw thread, along its own axial-movement, the adjusting set of movement will will drive connecting rod movement, and connecting rod will will push
Skewback movement is adjusted, telescopic rod movement will be will push by adjusting skewback, so that second spring active length reduces, at this time half
The torque that relative motion occurs for circular groove and driving wheel will become larger, to reach the mesh for adjusting torque limiter critical torque value
