Abstract
The invention provides a transmission mechanism for magnetic gears. The transmission mechanism for the magnetic gears comprises a pair of gears engaged with each other. Gear teeth of the gears are made of ferromagnetic substances. A wheel body of each gear internally comprises permanent magnets which are circumferentially and uniformly distributed. All the permanent magnets are magnetized in the radial direction of the gears, and the same polarities of all the permanent magnets are consistently and radially outward or consistently and radially inward. According to the transmission mechanism for the magnetic gears, rigid contact and collision among the gear teeth engaged with one another can be weakened, and thus the durability of the transmission mechanism for the magnetic gears is improved.
Description
Technical field
The present invention relates to mechanical transmission mechanism field, especially, is a kind of gear drive.
Background technique
In gear drive, need to realize transmission by the engagement of gear tooth; In the engagement process of the gear teeth, the surface rigidity contact of two gear teeth, and close to linear contact lay, area of contact is less, causes face of gear easily to wear and tear; In addition, when gear drive coordinates accurate not, the engagement of the gear teeth, along with the collision of the flank of tooth, more easily damages.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of magnetic-gear driving mechanism, this driving mechanism can weaken intermeshing rigid contact and the collision of taking turns between cog, thus improves the serviceability of gear drive.
The technological scheme that actualizing technology object of the present invention adopts is: this magnetic-gear driving mechanism comprises intermeshing a pair gear; The gear teeth of described gear are made up of ferromagnetics, and the wheel body inside of described gear includes the uniform permanent magnet of circumference; Each described permanent magnet along the diametrical magnetization of described gear, and the consistent radially outward of the homopolarity of each permanent magnet or consistent radially-inwardly.
As preferably, on the wheel body of described gear, the region be within the ring of encirclement that described permanent magnet formed is made up of non-ferromagnetic; To make the magnetization of permanent magnet concentrate on gear teeth region, to improve gear teeth magnetic, in addition, the region within the permanent magnet ring of encirclement can being made mutually not suppress because being magnetized by homopolarity, causing magnetic energy decay faster.
As preferably, each described permanent magnet mutually near, surround ringwall shape, be embedded in the groove that is opened on gear wheel body; The program can make gear tooth portions obtain high-strength magnetic, but magnetic energy is easy to decay.
As preferably, the body surfaces circumference of described gear is evenly equipped with the chute radially extended; One piece of described permanent magnet that can be free to slide in chute is respectively equipped with in each described chute; Further, described gear is made up of ferromagnet at the external lateral portion of the circumference that the outer end of described chute is linked to be, and remaining part is formed by non-ferromagnetic.
Beneficial effect of the present invention is: this magnetic-gear driving mechanism is in transmission process, because the gear teeth of pitch wheel remain homopolar-repulsion, therefore, each gear teeth are before engagement, owing to being subject to magnetic repulsion effect, make their rigid collision be subject to obvious buffering, and keep less rigid contact after entering engagement; Thus reduce the wearing and tearing of the gear teeth, gear drive can be made durable in use.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this magnetic-gear driving mechanism embodiment one.
Fig. 2 is the schematic diagram of this magnetic-gear driving mechanism embodiment two.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment one shown in Fig. 1, this magnetic-gear driving mechanism comprises intermeshing a pair gear; The gear teeth 11 of described gear are made up of ferromagnetics, and the wheel body of described gear is divided into ringwise ferromagnetics part 121, and the non-ferromagnetic material part 122 of this ferromagnetics part 121 inside; The center of described non-ferromagnetic material part 122 has bearing hole 10; Described ferromagnetics part 121 is one-body molded with the gear teeth 11; And the inner ring side of described ferromagnetics part 121 offers annular groove, in this annular groove, be equipped with circumference permanent magnet 13 uniform, close to each other; Each described permanent magnet 13 along the diametrical magnetization of described gear, and the consistent radially outward of the homopolarity of each permanent magnet 13 or consistent radially-inwardly.
Above-mentioned magnetic-gear driving mechanism is in transmission process, because the gear teeth 11 of pitch wheel remain homopolar-repulsion, therefore, each gear teeth 11 are before engagement, owing to being subject to magnetic repulsion effect, make their rigid collision be subject to obvious buffering, and keep less rigid contact after entering engagement; Thus reduce the wearing and tearing of the gear teeth 11, gear drive can be made durable in use.
In the embodiment two shown in Fig. 2, this magnetic-gear driving mechanism comprises intermeshing a pair gear; The gear teeth 11 of described gear are made up of ferromagnetics, and the wheel body of described gear is divided into integrated, the ringwise ferromagnetics part 121 with the gear teeth 11, and the non-ferromagnetic material part 122 of this ferromagnetics part 121 inside; The central authorities of described non-ferromagnetic material part 122 offer bearing hole 10; Described non-ferromagnetic material part 122 inner circumferential is evenly equipped with the chute 130 radially extended, and the outer end of described chute 130 extends to described ferromagnetics part 121; Be respectively equipped with one piece of permanent magnet 13 that can be free to slide in chute 130 in each described chute 130, equally, each described permanent magnet 13 along the diametrical magnetization of described gear, and the consistent radially outward of the homopolarity of each permanent magnet 13 or consistent radially-inwardly.According to embodiment two, when gear stationary or low speed rotation, each permanent magnet 13 is less due to centrifugal force, and will be equilibrated at each chute 130 comparatively inner end, described ferromagnetics part 121 is subject to less magnetization, to keep less magnetic decay; And when gear pair high-speed drive, then each permanent magnet is under larger centrifugal action, slide into the comparatively outer end of each chute 130, make the gear teeth 11 be subject to stronger magnetization, thus to sacrifice magnetic energy to weaken the mesh impact of wheel between cog.This embodiment two can make driving mechanism magnetic energy loss in a non-operative state significantly reduce.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
