Ingot butt rotates synchronously；After revolving speed increase, upper wharve magnet ring and lower wharve magnet ring generate magnetic field, and changing magnetic field generates main shaft
Axial active force achievees the effect that balance external force suffered by spindle blade, between the first radial bead, the first radial big magnet ring and the
The magnetic field generated between two radial beads, big magnet ring, radial active force, when making spindle high-speed rotation, nothing are generated to spindle blade
Contact, no friction.In actual job, spindle blade high-speed rotation, outside and the bobbin of spindle blade tight fit are started turning, by two strands or
Two strands or more of single thread twisting one strand of synthesis.In traditional spindle support construction, roller bearing shape is filled between wharve and outer sleeve
Cooperate at rolling, spindle is to be slidably matched with ingot butt, and vibration is beaten when work, and noise is big, is needed plus lubricating oil, fills wind spring and damps
Device, this keeps spindle supporting framework complicated, increased costs, while the revolving speed of spindle is also restricted, and plain edition turns left 10,000
The right side, high-speed type just two are played well, and working efficiency is low.The present invention can be made between spindle and bolster by the effect of Permanent-magnet bearing by sliding
Dynamic friction is changed to windage, contactless, no friction, and without lubrication, the measures such as damping, structure is simpler, improves simultaneously
Revolving speed can make spindle revolving speed be increased to 200,000 turns by more than 3,000 turns, and twisting efficiency improves, and the quality of twisting also greatly improves,
It reduces equipment cost while improving work efficiency.
