Description
Technical field
The present invention relates to mechanical transmission mechanism field, is a kind of gear drive especially.
Background technology
, it is necessary to realize transmission by the engagement of gear tooth in gear drive；In the engagement process of the gear teeth,
The surface rigidity contact of two gear teeth, and close to linear contact lay, contact area is smaller, causes face of gear easily to wear；In addition, work as tooth
Wheel drive mechanism coordinate it is not inaccurate enough in the case of, the engagements of the gear teeth along with the flank of tooth collision, it is easier to damage.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of magnetic-gear transmission mechanism, the transmission mechanism can be with
Weaken rigid contact and the collision of intermeshing wheel between cog, so as to improve the durability of gear drive.
Technical scheme is used by the present invention realizes technical purpose：The magnetic-gear transmission mechanism includes intermeshing
A pair of gears；The gear teeth of the gear are made up of ferromagnetics, and circumferential uniform permanent magnet is included inside the wheel body of the gear；
Diametrical magnetization of each permanent magnet along the gear, and each permanent magnet homopolarity it is consistent radially outward or it is consistent radially-inwardly.
Preferably, the region within the ring of encirclement formed on the wheel body of the gear, in the permanent magnet is by non-ferric
Magnet is formed；So that the magnetization of permanent magnet concentrates on gear teeth region, to improve gear teeth magnetic, in addition, can make permanent magnet bag
Region within enclosure does not suppress mutually because being magnetized by homopolarity, causes faster magnetic energy to be decayed.
Preferably, each permanent magnet mutually abuts, ringwall shape is surrounded, embedded at the groove being opened on gear wheel body
It is interior；The program can make gear tooth portions obtain high-strength magnetic, but magnetic energy is easy to decay.
Preferably, the body surfaces of the gear are circumferentially evenly equipped with the chute radially extended；Divide in each chute
She You not one piece of permanent magnet that can be in chute slidably；Further, the gear is in the outer end of chute institute
The Outboard Sections for the circumference being linked to be are made up of ferromagnet, and remainder is formed by non-ferromagnetic.
The beneficial effects of the present invention are：The magnetic-gear transmission mechanism is in transmission process, due to intermeshing tooth
The gear teeth of wheel remain homopolar-repulsion, and therefore, each gear teeth, due to being acted on by magnetic repulsion, make their rigidity before engagement
Collision is significantly buffered, and keeps less rigid contact after engagement is entered；So as to reduce the abrasion of the gear teeth, tooth can be made
Wheel drive mechanism is durable in use.
Brief description of the drawings
Fig. 1 is the schematic diagram of this magnetic-gear transmission mechanism embodiment one.
Fig. 2 is the schematic diagram of this magnetic-gear transmission mechanism embodiment two.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples：
In the embodiment one shown in Fig. 1, the magnetic-gear transmission mechanism includes intermeshing a pair of gears；The tooth
The gear teeth 11 of wheel are made up of ferromagnetics, and the wheel body of the gear is divided into ferromagnetics part 121 in a ring, and the ferromagnetics portion
The non-ferromagnetic material part 122 divided inside 121；The center of the non-ferromagnetic material part 122 is provided with bearing hole 10；The ferromagnetics portion
121 are divided to be integrally formed with the gear teeth 11；And the inner ring side of the ferromagnetics part 121 offers annular groove, in the annular groove
Equipped with circumferential permanent magnet 13 uniform, close to each other；Diametrical magnetization of each permanent magnet 13 along the gear, and each permanent magnetism
The homopolarity of body 13 it is consistent radially outward or it is consistent radially-inwardly.
Above-mentioned magnetic-gear transmission mechanism is in transmission process, because the gear teeth 11 of pitch wheel remain same
Pole is repelled each other, and therefore, each gear teeth 11, due to being acted on by magnetic repulsion, make their rigid collision significantly be delayed before engagement
Punching, and keep less rigid contact after engagement is entered；So as to reduce the abrasion of the gear teeth 11, gear drive can be made prolonged
It is durable.
In the embodiment two shown in Fig. 2, the magnetic-gear transmission mechanism includes intermeshing a pair of gears；The tooth
The gear teeth 11 of wheel are made up of ferromagnetics, and the wheel body of the gear is divided into and the gear teeth 11 are integrally formed, ferromagnetics portion in a ring
The non-ferromagnetic material part 122 divided inside 121, and the ferromagnetics part 121；The center of the non-ferromagnetic material part 122 opens up
There is bearing hole 10；The inner circumferential of non-ferromagnetic material part 122 is evenly equipped with the chute 130 radially extended, the chute 130 it is outer
End extends to the ferromagnetics part 121；One piece is respectively equipped with each chute 130 can be in chute 130 slidably
Permanent magnet 13, equally, diametrical magnetization of each permanent magnet 13 along the gear, and each permanent magnet 13 homopolarity it is consistent radially to
It is outer or it is consistent radially-inwardly.According to embodiment two, in gear stationary or low speed rotation, each permanent magnet 13 due to centrifugal force compared with
It is small, each chute 130 will be equilibrated at compared with inner end, the ferromagnetics part 121 is by less magnetization, to keep less magnetic
Decay；And in gear pair high-speed drive, then each permanent magnet slides into the relatively outer of each chute 130 under larger centrifugal action
End, make the gear teeth 11 by stronger magnetization, so as to weaken the mesh impact of wheel between cog to sacrifice magnetic energy.The embodiment two
The magnetic energy loss of transmission mechanism in a non-operative state can be greatly decreased.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
