Abstract
The utility model relates to a non-contact type space cross drive magnetic gear, which is a hollow cylinder magnetic gear glued and molded by Nd-Fe-B permanent magnetic material. The magnetic poles of the magnetic gear are arranged spirally on the external surface of the magnetic gear in 45 DEG, and each two adjacent magnetic poles have reversed polarities. The two magnetic gears are assembled crosswise and are not in contact with each other with effective clearance between the two gears. A torque can be produced through gravitations and repulsions between magnetic poles, thereby enabling a driving gear to drive a driven gear to rotate. The utility model has the advantages of dust prevention, mechanical wear resistance, low noise, little shock, long service life, safety and reliability, etc.
Description
Technical field
The utility model relates to a kind of magnetic gear, particularly a kind of contactless space crossed transmission magnetic gear, be used for transmission device or equipment, be applied to require the occasion of dustlessization of production environment especially, and the transmission direction of axle is had living space on the transmission device or equipment that intersect to require.
Background technique
Traditional mechanical gear driving mechanism owing to be the contact-type transmission all, can produce particulate and dust in the course of the work inevitably.And at some high-technology fields, its requirement to production environment is very harsh, so cleanization degree height occurred having in current drive technology, the magnetic gear of the non-gear contact of advantages such as nothing wearing and tearing.But technical at magnetic gear in the past can't be realized the transmission between the space crossed axle of non-contact, and magnetic gear mostly to be splicing inserted, its working process is comparatively complicated.(as patent 200610112951.3A Magnetic gear wheel with amtipodal permanent magnetic structure and magnetic gear train thereof)
The model utility content
The purpose of this utility model is to provide a kind of can realize contactless space crossed transmission magnetic gear, and it can provide the safety production environment of cleaning, low noise, low vibrations.
In order to achieve the above object, the utility model adopts following technical proposals:
A kind of contactless space crossed transmission magnetic gear comprises a magnetic gear, it is characterized in that:
1) its magnetic pole with the S utmost point and N interpolar every being distributed in the magnetic gear surface,
2) the magnetic pole inclination angle is 45 ° of lead angles,
3) end face of all magnetic poles forms a smooth complete circle cylinder.
Above-mentioned magnetic gear is Nd-Fe-B permanent magnetic material bonding press body, the magnetic pole that its magnetic pole constitutes the radial surface multipole magnetization for this bonding press body.
Compared with prior art, the utlity model has following conspicuous substantive distinguishing features and advantage: magnetic gear of the present utility model has simple in structure, easy to make, the transmission agency of realization conventional gears that can be contactless, and than having dustproof and anti-mechanical wear, noise is low, vibrations are little, advantage such as safe and reliable.Transmission between the intersecting axle of energy implementation space, 45 ° of magnetic pole inclination angles of magnetic gear of the present utility model.
Description of drawings
Fig. 1 is the structural representation of embodiment's magnetic gear of the utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the driving mechanism schematic representation that Fig. 1 embodiment uses.
Embodiment
A preferred embodiment of the present utility model is: referring to Fig. 1 and Fig. 2.This contactless space crossed transmission magnetic gear is a Nd-Fe-B permanent magnetic material bonding press body, its smooth outer surface and complete, and through the magnetic pole that its cylindrical outer surface magnetic pole is constituted for the radial surface multipole magnetization, adjacent pole is a heteropole.Show among Fig. 1 that this contactless space crossed transmission magnetic gear is a complete cylindrical body, Fig. 2 shows that its magnetic pole angle of inclination is 45 ° of lead angles.As shown in Figure 3,2 above-mentioned magnetic gears are installed by space crossed axle, two magnetic gears are non-contact, leave the effective clearance therebetween, and 45 ° of magnetic poles of these 2 magnetic gears are just in time coincide to realize transmission.Gear transmission of the present utility model is not the gear teeth meshing transmission, and it is to produce moment of torsion to realize transmission by suction between the both positive and negative polarity between magnetic gear and repulsion.
The concrete transmission working principle of contactless space crossed transmission magnetic gear: after at first as stated above two magnetic gears being installed, when magnetic gear 1 (driving wheel) when rotating, the polarity at label 3 places is N on the tentative gear 1, and the polarity at label 5 places is S on this moment gear 2, then this moment, the generation of the N and the S utmost point attracted each other, when so gear 1 rotates, because magnetic pull effect, corresponding rotation also can take place in gear 2, and the polarity at label 4 places is the S utmost point on the gear 1, after then gear 1 rotates, the magnetic pole at its label 4 places also can owing to gear 2 on the magnetic pole at label 5 places owing to be homopolarity, so also can produce mutual expelling force, and with gear 2 on label 6 places be that heteropole is inhaled mutually, rotate thereby also promote gear 2.
Claims (2)
1. a contactless space crossed transmission magnetic gear comprises a magnetic gear, it is characterized in that:
