Embodiment
Be further described below in conjunction with the technical scheme of the embodiment shown in the Figure of description the application.
Referring to Fig. 1, be first embodiment that utilizes the transmission device of permanent magnet, comprise power output and drive part, wherein, the power output has the non magnetic main shaft 4 that is bearing in bearing 3, and the fixing a plurality of sheets 5 of being inhaled of shape are in the shape of a spiral complied with axially on main shaft 4 surfaces; Drive part has guide wheel 9 and driving-belt, and driving-belt can use flat belt or cog belt.Among the embodiment, cog belt 8 is around two guide wheels 9, two guide wheels 9 are fixed in two parallel guide wheel shaft 13 ends, a plurality of permanent magnets 10 directly are fixed on cog belt 8 outer surfaces, cog belt 8 and main shaft 4 axially parallels in the service area, permanent magnet 10 and inhaled between the sheet 5 and have the gap, the spacing of adjacent permanent magnet 10 equals to be inhaled on the main shaft 4 pitch of sheet 5 spirals.Main shaft 4 both end sides have bearing 3, and to reduce the pivoting friction resistance of main shaft 4, the one end is output wheel 1 fixedly, as the clutch end of the transmission device that utilizes permanent magnet.Having a guide wheel 9 at least in two guide wheels 9 of drive part is driving wheels, and this driving wheel is the toothed wheel that is meshed with cog belt 8.When active guide wheel 9 rotations that driven by external force, the cog belt 8 of drive and guide wheel 9 engagements is fixed on permanent magnet 10 moving linearlies on the cog belt 8 in 9 motions of two guide wheels.Along with permanent magnet 10 edges travel forward with main shaft 4 parallel directions, helical arrangement is inhaled in the sheet 5 on the main shaft 4, the disengaging successively that has attracted to minimum range attracts, the sheet 5 of being inhaled in the place ahead is subjected to magnetic attraction successively, the sheet 5 of being inhaled that magnetic force does not constantly reach the place ahead minimum range is attracted to minimum range successively, and the moment of generation makes and inhaled the main shaft 4 that sheet 5 fixedlys connected and rotate.Because the spacing between the permanent magnet 10 equals the pitch that helical form is inhaled sheet 5 on the main shaft 4, when previous permanent magnet 10 moves to guide wheel 9 places and deactivates state, the permanent magnet 10 in back just in time enters operating state, thereby makes main shaft 4 can carry out the running of continous-stable.According in using to transmitting the requirement difference of power, magnetic intensity that can be by changing permanent magnet 10, inhaled the size of sheet 5 and at the number of being inhaled the spiral of sheet 5 on number density, the main shaft 4 that is provided with on the main shaft 4, change and adjust the coupling of input power and power output, satisfy instructions for use.Permanent magnet 10 and inhaled between the sheet 5 and have the gap, the two does not produce mechanical friction, reduces machinery noise and reduces running resistance, simultaneously, in case can realize buffering herein when mechanical overload takes place, guarantees the safety of whole machinery.Certainly, this gap should be little, to improve the magnetic attraction efficient of permanent magnet 10.To guarantee permanent magnet 10 and inhaled gap between the sheet 5 in order to make, permanent magnet 10 drive parts are arranged in the pedestal 7, pedestal 7 is towards main shaft 4 direction fixed guides 6, and it is close to main shaft 4 directions that guide rail 6 has limited cog belt 8, has guaranteed permanent magnet 10 and has been inhaled gap between the sheet 5.In order to reduce the mechanical friction between cog belt 8 and the guide rail 6, respectively has a roller 11 in permanent magnet 10 both sides, roller 11 places on the permanent magnet 10 by roller pivot pin 12, roller 11 contacts with guide rail 6 inner faces, make mechanical friction between cog belt 8 and the guide rail 6 change into the rolling of roller 11, reduced the frictional resistance loss.
Referring to Fig. 2, Fig. 3, drive part is arranged in the pedestal 7, and two guide wheels 9 are fixed in two parallel guide wheel shaft 13 ends.Fixed guide 6 above the pedestal 7.The parallel axes of permanent magnet 10 movement locus and main shaft 4.Inhaled sheet 5 and made, enable to be attracted by permanent magnet 10 for ferromagnetic material.It protrudes in main shaft 4 surfaces, and is tangent line with main shaft 4 surfaces and fixes, and the sheet 5 of being inhaled of sheet is attracted by permanent magnet 10 with maximum area, to obtain maximum rotating torque, breaks away from the attraction of permanent magnet 10 simultaneously with minimum area.Inhaled sheet 5 also can be directly in the shape of a spiral shape be embedded in the surface of main shaft 4, do not protrude in the surface of main shaft 3, moment still can rotate.Inhaled sheet 5 and also can be adopted permanent-magnet materials, will make its magnetic pole opposite when on main shaft 4, installing, with the moment that rotates with relative permanent magnet 10 magnetic poles.
Referring to Fig. 4, Fig. 5, Fig. 6, by the tectonic relationship of three-view diagram explanation permanent magnet 10 with peripheral associated components, permanent magnet 10 is fixed on the cog belt 8, permanent magnet 10 both sides are provided with roller 11 by roller pivot pin 12, roller 11 contacts with guide rail 6, and rolls along guide rail 6, this just make permanent magnet 10 can either with inhaled sheet 5 and kept little gap, can avoid contact friction again, reduce the frictional resistance between cog belt 8 and the guide rail 6.Fixedly connected between permanent magnet 10 and the cog belt 8 can be that rivet is connected, or bolt connects.
Referring to Fig. 7, Fig. 8, this is second embodiment that utilizes the transmission device of permanent magnet, and the difference of it and first embodiment has been to change the direction that is provided with of drive part, and the power output changes.Because the variation of the relative position between drive part and the power output, correspondingly to change the setting of permanent magnet 10 on cog belt 8, with maintenance permanent magnet 10 and inhaled correct operating state between the sheet 5.Because guide wheel 9, cog belt 8, permanent magnet 10 be in the operation of horizontal plane direction,, between permanent magnet 10 and cog belt 8, installed permanent magnet seat 15 additional in order to make permanent magnet 10 can be correct enter working region work and release the working region.
Referring to Fig. 9, Figure 10, Figure 11, Figure 12, from the change of details explanation second embodiment.Permanent magnet 10 is arranged on the end face of permanent magnet seat 15, the installed surface and the cog belt 8 that are an angle of 90 degrees with its end face of permanent magnet seat 15 fix, and this just makes the permanent magnet 10 that has changed cog belt 8 running faces still can keep the operating state correct with the main shaft 4 of power output.Because cog belt 8 is in vertical direction in the side in working order the time, cog belt 8 can produce sagging in the working region, the spacing of the setting between permanent magnet 10 and the main shaft 4 is strengthened, make permanent magnet 10 and the attraction of being inhaled between the sheet 5 reduces, cause the deterioration of operating state.In order to solve because of changing the problem that direction produces, below cog belt 8 on the pedestal 7, set up slideway 14, make cog belt 8 be subjected to the support of slideway 14, unite with roller 11, the guide rail 6 of permanent magnet 10, from both direction clamping up and down, keep the correct operating state of cog belt 8 and permanent magnet 10.Cog belt 8 moves in slideway 14 and can produce frictional resistance, slideway 14 can be set to ball slideway or roller slideway for this reason, makes operation more smooth and easy.
