Abstract
A method and equipment using rotary magnetic poles to control the separation or binding between two objects to transfer torque is disclosed. A permanent magnet is attached to the end of driven shaft connected to load. A rotary magnet rotating in a pair of magnetic yokes to change magnetic poles is arranged to the end of drive shaft. When said rotary magnet is rotating, its N and S poles alternatively face aginast said permanent magnet to transfer torque or not on the basis of the principle that like polarities repel one another and opposite polarities attact each other.
Description
Technical field the present invention relates to mechanical clutch means, particularly a kind ofly utilizes reversal of magnetism to control the object clutch and transmits the method and the device thereof of torsion.
Background technique need be interrupted transmission torsion occasion at present, general all is to adopt the mode of clutch to control the clutch of object, and the clutch mode generally has following several mode: 1. mechanical friction sheet engaging and disengaging gear, this clutch mode, need give friction plate a great pressure, make between the friction plate the enough frictional force of maintenance transmit torsion, this mode is that separate or merge all needs to apply bigger power.2. electromagnetic clutch device, this mode need give pole coil a bigger electric current, to keep can having powerful the suction-combining force between driving shaft and the driven axle, realizes the transmission of torsion, and this mode needs bigger electric energy support.
Summary of the invention the objective of the invention is to avoid above-mentioned the deficiencies in the prior art, provide a kind of power consumption less, labour-saving clutch method and the device of realizing this method.
The present invention adopts following method, and a kind of rotary pole is controlled the object clutch and transmitted the method for torsion: at first in passive running shaft end permanent magnet is set, this running shaft connects load; Be provided with one at the active rotation shaft end then and in involutory yoke mesopore, rotate the also rotary magnet of conversion permanent magnetism magnetic pole; When live axle driven rotary magnet rotated, the N utmost point of rotary magnet or the S utmost point were alternately in the face of passive running shaft; Utilize the principle that the magnetic bodies same sex is repelled each other, there is a natural attraction between the sexes, when the magnetic pole of rotary magnet and permanent magnet apparent surface magnetic pole were different, passive running shaft and the adhesive of active rotation axle can be transmitted torsion; When the magnetic pole of rotary magnet was identical with permanent magnet apparent surface magnetic pole, passive running shaft and active rotation axle broke away from, and the torsion transmission is ended.
Device as the realization said method: be included in the permanent magnet that passive running shaft end is provided with; Be provided with yoke at the active rotation shaft end, rotary magnet rotates around live axle in this yoke mesopore, rotate this rotary magnet and make its N utmost point or the S utmost point, cause between active rotation axle and the passive running shaft adhesive or separate, transmit or end to transmit torsion alternately in the face of passive running shaft.
The present invention can utilize the characteristics of magnetic material as much as possible, realizes the purpose of clutching labor-saving, energy saving.
Description of drawings
Fig. 1 is a schematic representation of the present invention.
Fig. 1 is the schematic representation that the passive running shaft of the present invention adopts rotary pole.
Embodiment further describes embodiments of the invention below in conjunction with accompanying drawing.
By finding out among Fig. 1, a kind of rotary pole is controlled the object clutch and transmitted the method for torsion: at first in passive running shaft 3 ends permanent magnet 31 is set, this running shaft connects load; Be provided with one then in active rotation axle 4 ends and in involutory yoke 1 mesopore 11, rotate the also rotary magnet 2 of conversion permanent magnetism magnetic pole; When 2 rotations of live axle 21 driven rotary magnets, the N utmost point of rotary magnet 2 or the S utmost point are alternately in the face of passive running shaft 3; Utilize the principle that the magnetic bodies same sex is repelled each other, there is a natural attraction between the sexes, when the magnetic pole of rotary magnet 2 and permanent magnet 31 apparent surface's magnetic poles were different, passive running shaft 3 and 4 adhesives of active rotation axle can transmit torsion; When the magnetic pole of rotary magnet 2 was identical with permanent magnet 31 apparent surface's magnetic poles, passive running shaft 3 broke away from active rotation axle 4, and the torsion transmission is ended.
By among Fig. 2 as can be known, permanent magnet 31 also can be designed to the mode of rotation transformation magnetic pole, it comprises the rotary magnet 313 that is arranged on 311 mesopores, 312 interior rotations of involutory yoke and conversion permanent magnetism magnetic pole, this rotary magnet is subjected to external force control rotation, thereby this permanent magnet of conversion and active rotation axle 4 apparent surfaces' polarity, this scheme can better be controlled the clutch of object.
By among Fig. 1 as can be known, as the device of realizing said method: be included in the permanent magnet 2 that passive running shaft 3 ends are provided with permanent magnetism; Be provided with yoke 1 in active rotation axle 4 ends, rotary magnet 2 rotates around live axle 21 in this yoke mesopore 11, rotate this rotary magnet and make its N utmost point or the S utmost point, cause between active rotation axle 4 and the passive running shaft 3 adhesive or separate, transmit or end to transmit torsion alternately in the face of passive running shaft 3.
By among Fig. 2 as can be known, for the better clutch of control object, described permanent magnet 31 is designed to comprise and is arranged in involutory yoke 311 mesopores 312, is subjected to the rotary magnet 313 of external force control rotation and conversion permanent magnetism magnetic pole, by this permanent magnet of rotation transformation and active rotation axle 4 apparent surfaces' polarity.
By among Fig. 1 as can be known, in order to make alternating magnetic field in the reversal of magnetism process, reduce remanent magnetism, described yoke 1 is selected for use by the some silicon steel sheets that can not produce remanent magnetism and is formed by stacking.
