Star roller screw type electric speed regulation cartridge type magnetic coupling drives planetary roller screw component using inner rotor motor, outside motor
Rotor keeps rotating synchronously with center driving axis 11 using synchronous disk 9 and expansion set 10, opposing stationary.C-type, D type traveling star roller silk
Thick stick type electric speed regulation cartridge type magnetic coupling uses outer rotor motor driven planetary roller screw component, and motor internal rotor is direct
It is fixed on center driving axis 11, or androgynous using motor center axis and center driving axis 11, is combined into one.For A type, Type B,
C-type, D type traveling star roller screw type electric speed regulation cartridge type magnetic coupling, the fixed cartridge module of magnetic patch, planetary roller screw component,
Driving motor and center driving axis etc. form internal rotor, and induction cartridge module and flange shaft sleeve etc. form outer rotor.Inner and outer Rotator according to
The interaction of the induced magnetic field generated on the permanent magnetic field and induction cylinder that magnetic patch generates between the two carrys out passing movement.Speed regulation
When, rotor is controlled by controlling the sense of current into motor and the opposite of stator turns to, and planet is driven by motor
Roller screw component makes rotation motion be in line movement, drives the fixed cartridge module of magnetic patch to slide along center driving axis, to adjust
The size (the magnetic field coupling area between inner and outer rotors) of the induced magnetic field generated on whole induction cylinder, to change the big of transmitting power
It is small, achieve the purpose that variable speed energy saving.When speed regulation, electromagnetic hazard will be will cause by being exposed to the magnetic patch outside magnetic coupling, and there is safety
Hidden danger.After installing shield additional, shield should be controlled at a distance from internal rotor, hypotelorism is then equivalent to and has installed one additional
Forced brake device, causes energy loss.In addition, magnetic patch brittleness is big, and it is frangible, so protected working must be carried out.Planetary roller screw
What component was adjusted in speed regulation is the opposing coupler area incuded between cylinder and magnetic patch fixed cylinder, so can also be by planetary roller
Lead screw assembly is coupled with induction cylinder, and driving induction cylinder achievees the purpose that speed regulation axially movable.

Structural representation, connection uses expansion set, Type B, c-type, D type traveling star roller screw type electric speed regulation cartridge type magnetic force coupling between transmission shaft
Clutch can also be done so, but this scheme can only be used in low load situation and axis alters very small situation, the reason is as follows that: inner and outer rotors
Be not in contact with each other, but due to assembly when it is difficult to ensure that induction cylinder and magnetic patch fixed cylinder concentricity, so can be to motor center axis axis
Hold at bearing and load transmission axle bearing bearing at cause alternate stress (effect of magnetic field coupling additional bending moment) so that axis mistake
Spend wear-out failure.In addition, the influence that axis is altered will cause bumpy running, accident will cause when serious.Generally speaking, such scheme
It is used with caution.
