Outfan is provided with power output gear, and power output gear is provided with cavity towards the side of castle wheel 5, and the second interface 61 is arranged
In cavity interior walls.
The power take-off mechanism also include driven turbine wheel 20, the driven shaft be driven worm screw 10, driven worm screw 10 lead to
Cross driven turbine wheel 20 to be driven with drive sleeve 3.The castle wheel 5 is fixedly connected by lateral pin 30 with driven worm screw 10.
72 one end of the sleeve is connected with the lower cover 21 of gear-box, and 72 other end of sleeve is then provided with outer end cap 73,9 liang of screw rod
End rotates respectively and is undertaken on lower cover 21 and outer end cap 73.
The central axis of above-mentioned drive sleeve 3 is parallel with the central axis of motor 1.
Its operation principle is：Arc elastic blade 53 causes the first interface 52 to paste toward the second interface 61 under normal conditions
Closely, when motor 1 works, you can the power of output is passed through active worm screw 11 and active turbine 6 passs castle wheel 5, then
Drive sleeve 3 is passed to by the driven worm screws 10 of 5 Jing of castle wheel and driven turbine wheel 20；It is when drive sleeve 3 is subject to certain obstruction power, main
The power of dynamic worm screw 11 and the output of active turbine 6 is converted to other kinetic energy and makes the first interface 52 exit the second interface 61,
Arc elastic blade 53 is swung to 5 center position of castle wheel, the other elastic deformation cavity quilt for being formed on the inside of arc elastic blade 53
Compression, so no longer drive drive sleeve 3 to work, and active turbine 6 then skids on the first interface 52.Therefore, the elevator
After the drive sleeve 3 of structure driver is connected with other elevating movement devices or other linear motion devices, even if elevating movement device
The object with certain resistance is bumped against during decline, also can stop motion in time, with reduce object is damaged.When resistance disappears
Afterwards, arc elastic blade 53 resets, and castle wheel 5 recovers proper motion.
