The terminology used in the description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example 1

As shown in fig. 1-3, an unpowered hysteresis lag formula cable drum includes slip ring case 2, take-up reel 3, first sprocket 4, hysteresis lag head 5 through connecting axle 1 coaxial coupling, hysteresis lag head 5 include shell 6 and inner disc 7, and set up the hysteresis lag subassembly between shell 6 and the inner disc 7, shell 6 and first sprocket 4 fixed connection, inner disc 7 and connecting axle 1 fixed connection, take-up reel 3 and connecting axle 1 fixed connection, 3 both sides of take-up reel respectively set up a backup pad 8, the casing of slip ring case 2 be fixed in one of them backup pad 8, the bottom of flatbed 9 is connected to two backup pads 8 still includes second sprocket 10, the coaxial fixed connection of a wheel 11 of second sprocket 10 and flatbed 9, set up chain 12 between first sprocket 4 and the second sprocket 10.

Hysteresis lag subassembly including fixed setting at the inboard magnet steel ring 13 of shell 6 to and a plurality of permanent magnets 14 of evenly distributed on inner disc 7, a plurality of permanent magnets 14 and the relative distribution of magnet steel ring 13, have the clearance between permanent magnet 14 and the magnet steel ring 13.
