Abstract
A kind of spindle with magnetic bearing, this spindle is in the appearance and size that keeps existing spindle, keep on the basis of existing spindle to spindle blade machinery location, in the lower end of spindle blade the magnetic bearing structure of being made up of the different in nature permanent-magnet pole of annular is set again, with carry out to spindle blade axially and magnetic confinement radially, and magnetic confinement is occupied an leading position, make mechanical constraint withdraw to secondary status, thereby prolong the service life that makes spindle more than 1 times, also save energy consumption simultaneously.
Description
The present invention relates to a kind of spindle with magnetic bearing.
Existing spindle, radial location is done by needle bearing in the upper end of spindle blade, it is pointed that the lower end of spindle blade makes awl, and by ingot base cone cover supporting location, spindle blade is by the strap transmission, rotating speed with 18000 rev/mins uprightly rotates, because the friction between ingot point and the tapered sleeve is sliding friction, it is very big to wear and tear, and every spindle can only use 2 years, ingot point wearing and tearing are main causes that spindle damages, and the annual spindle that damages because of the ingot point is more than 1,000 ten thousand.
In order to prolong the service life of ingot point, improve the life cycle of spindle, save the energy consumption of spindle, the spy provides spindle with magnetic bearing.
Spindle with magnetic bearing is in the appearance and size that keeps existing spindle, keep on the basis of existing spindle to spindle blade machinery location, in the lower end of spindle blade the aspiration-type magnetic bearing structure of being made up of the different in nature permanent-magnet pole of annular is set again, spindle blade is carried out axially and magnetic confinement radially, and magnetic confinement is occupied an leading position, make original mechanical constraint retreat to less important secondary status, to reach service life that prolongs the ingot point and the purpose that cuts down the consumption of energy, in the accompanying drawings, the structural member that existing spindle is kept has: (1)-(13), (21) and (23), its function, making and installation are with original identical, in the accompanying drawings, newly-installed structural member has: (14)-(19), (20) and (22), wherein, (17) and (18) be the permanent-magnetic clamp of a pair of aspiration-type, axial charging, the central lines of the center line of magnet ring and spindle blade (1), magnet ring (17) is last, for deciding magnet ring, it is fixing by magnet ring overcoat (15) and bolster (9), and magnet ring (18) is moving magnet ring down, it and the interior cover of magnet ring (16) are fixed, also stretch out from the endoporus of deciding magnet ring (17) upper end of cover in the magnet ring simultaneously, should be gapped between the endoporus of the upper end of (16) and (17), so that doing noncontact in the endoporus of (17), the upper end of (16) rotates.(20) be lining, it and absorbing wind spring (23) are decided the height of magnet ring (17) jointly, the inwall of lining (20) should not contact with moving magnet ring (18), so that moving magnet ring can freely rotate therein, decide attraction between magnet ring (17) and moving magnet ring (18) and should be slightly less than the weight of spindle blade, when spindle blade (1) does not insert in the magnet ring in the cover (16), moving magnet ring (18) and decide magnet ring (17) and inhale together, after spindle blade (1) inserts, spindle blade (1) is pressed in its weight on the upper end of cover (16) in the magnet ring, cover (16) just will move magnet ring and depress a segment distance downwards in the magnet ring, fall up to the ingot point till the bottom of ingot base cone cover (21).Because moving magnet ring (18) is subjected to deciding the attraction that magnet ring (17) makes progress, this power is passed to spindle blade (1) by the upper end end face of cover (16) in the magnet ring, make spindle blade (1) be subjected to thrust upwards, thereby the ingot point is reduced to the axial contact force of ingot base cone cover, in addition, when two magnet rings are attracted each other, magnetic force has makes two magnetic poles in the face of neat character, this character has the radial centering effect, the radial vibration (14) that can reduce spindle blade is fairlead, and its effect is smooth centering when spindle blade is inserted, and (19) are the wind spring pad, its effect is to prevent absorbing wind spring (23) up-down vibration, and the effect of ingot base cone cover splicing sleeve (22) is a supporting ingot base cone cover (21).
Because the setting of magnetic bearing, magnetic force has produced axially and magnetic confinement power radially spindle blade, the ingot point reduces greatly to the contact force of ingot base cone cover, according to the service life of wearing and tearing theorem (wearing and tearing are directly proportional with normal pressure) spindle with magnetic bearing, compare with the service life of existing spindle, at least prolong 1 times, owing to the minimizing of frictional force, energy consumption also can descend to some extent simultaneously, and the spindle with magnetic bearing of new trial-production manually comparison shows that with old spindle, sensitivity improves, noise reduces, and machinery is taken temperature brightly in the cotton factory of Wuhan state, does not shake the head, do not generate heat, stable, serviceability is good.
The enforcement of spindle with magnetic bearing, except can be the special part of existing weaving factory (being spindle manufactory) produces, also used old spindle can be transformed into spindle with magnetic bearing, because the damage of spindle mainly is the wearing and tearing of ingot point and supporting member ingot base cone cover thereof, if repair the ingot point, change ingot base cone cover, the position that contacts of mobile spindle blade upper end and needle bearing, and magnetic bearing is set, and the spindle after handling like this, its serviceability will be above existing new spindle, this scheme is once with the cotton factory of Wuhan state, two manufacturers are fixed, manufacturer is ready to support and cooperate, and is ready that first batch of complete machine is on probation, with the spindle with magnetic bearing of old spindle transformation, the dress number of spindles in the whole nation is above 3,000 ten thousand, 20 yuan～25 yuan on every spindle if the spindle in the whole nation is all transformed, then can be created about 500,000,000 yuan of social values.
