Movement relation
In the present invention, after input shaft 1 is connect with external motor, under the driving of motor, input shaft 1 makees circle rotation
Movement, input shaft 1 is small torque, high speed rotary motion at this time；Duplex sleeve 7 is made to be eccentrically rotated fortune under deep groove ball bearing
Dynamic, the level-one internal layer magnetic patch group 9C and two level internal layer magnetic patch group 9D being bonded on duplex sleeve 7 are servo-actuated, under magneticaction, peace
Retainer plate 6 equipped with two level outer layer magnetic patch group 9B rotates, and the A end caps 4 for being equipped with level-one outer layer magnetic patch group 9A are fixed
, since retainer plate 6 and output shaft 2 are fixedly mounted, then output shaft 2 exports big torque, low-speed rotation.
The present invention devises a kind of retarder for lacking range magnetic gear with 2K-H types, and to be solved is how to improve
The technical issues of vibration, overload and the sealing of gear reduction unit lubricate, it is double that the present invention passes through the design on the circumference of duplex sleeve
Layer magnetic pole realizes the double reduction being driven without mechanical Contact Tooth wheel and all larger technological means of driving torque and gearratio, from
And reach big retarding than magnetic speed device technique effect.
