B, maximum value are determined, coil I and coil II are respectively taken out a subcoil, measure the interaction force when distance is zero between the two, the maximum force that this power can produce for both.Increasing distance between the two, only is 50% of maximum force up to interaction force, and then this spacing promptly can be used as the gap maximum value.
C, according to spindle rotor diameter and main shaft scaffold internal diameter, select suitable coil brace, make that gap width is between maximum value and minimum value between coil V and coil II.
Subcoil all circularizes arrangement in two coil groups, and coil I and coil II concentric, coil II is in coil I, and two coil groups are in same plane, by control circuit two coil groups are switched on, then produce interaction force between the coil of position counterpart in two coil groups.Do not have circular runout ideally at main shaft, when two coil groups radial distances equate everywhere, coil I to coil II to make a concerted effort be zero, promptly scaffold is zero to the active force of rotor external part.When main shaft generation circular runout is, the position of rotor external part axis and scaffold changes, coil I equates with the radial spacing of coil II no longer everywhere, distance reduces to locate the interaction force increase of corresponding coil, then reduce apart from increase place, coil I is non-vanishing with joint efforts to coil II's, and the big or small forward that should make a concerted effort is in the size of circular runout value, and the opposite direction of sensing main shaft circular runout, so this can effectively suppress to resist the circular runout of main shaft with joint efforts.On the control coil group magnitude of voltage and when adjusting voltage swing and guarantee that coil I and coil II are concentric according to the sensing capability of coil, coil I to coil II to make a concerted effort be zero.
Secondly, the main shaft scaffold is provided with magnetic coil III (hereinafter to be referred as coil III) and magnetic coil V (hereinafter to be referred as coil V), and the rotor external part is provided with magnetic coil IV (hereinafter to be referred as coil IV).Coil III, coil IV and coil V interior loop be circular array all, these three magnetic coil centers of circle are on same straight line, and this straight line is vertical with the disc of each coil groups, and promptly these three coils stack, and stack order and from top to bottom are followed successively by: coil V, coil IV, coil III.Have certain interval between coil V and coil IV, also have the same axial gap between coil IV and coil III, make this three coil electricities by voltage source, coil III and coil V can produce active force to coil IV.Above-mentioned axial clearance can be determined with reference to the method for radial clearance.Under main shaft does not have radially situation, between coil III, coil IV axially between gap and coil IV, coil V axially the gap location place equate, the main shaft scaffold to rotor to make a concerted effort be zero.When main shaft generation circular runout, coil IV run-off the straight, axial clearance between itself and coil III and coil V becomes inhomogeneous, scaffold is non-vanishing with joint efforts to rotor, the size of this power becomes positive relationship with the tilt angle that causes of beating, and point to the true dip direction opposite direction, this power forms moment loading to rotor, suppresses circular runout.
Simultaneously, at the size of spindle power, rotating speed, the output voltage of regulating voltage power supply 13 changes the active force between the magnetic coil group.Spindle power is big more, rotating speed is high more, and it is also big more to suppress the required electromagnetic torque of circular runout, can realize by the magnitude of voltage that increases voltage source.
Electromagnetic coil I, III on the scaffold, V directly are connected with power supply by lead; Thereby epitrochanterian electromagnetic coil II, IV are connected with voltage source 13 by secondary 12 bindings of magnetic coil lead 6 and the brush in being arranged on main shaft.
Simultaneously, magnetic coil I, magnetic coil II, magnetic coil III, magnetic coil IV, magnetic coil V contain the adjustable resistance that is used for finely tuning its current value.Magnetic coil I
-Each subcoil among the V is all connected with an adjustable resistance, regulates the current value of the resistance value of adjustable resistance with fine setting series connection with it subcoil, thereby finely tunes the magnetic intensity that this subcoil produces.For each magnetic coil, thereby the adjustable resistance that can regulate its inner sub-coil is realized the magnetic intensity unanimity that its inner sub-coil produces, and realizes the symmetrical distribution of magnetic coil Circumferential field intensity.Stability when the magnetic field that is symmetrically distributed helps the present invention relates to the running of machine tool chief axis vibration active restraining device.
