Description
Technical field
The utility model relates to mechanical transmission part technical field, particularly relates to a kind of novel magnetic gear.
Background technique
Gear transmission is most widely used a kind of type of belt drive in mechanical transmission, and it is mainly used to the rotation motion of transmission two between centers, and traditional dish cogged is integral gear, and different gear as multiple in spur gear, helical gear etc., is integral gear.But after long-term work uses, the gear teeth often easily damage, as spot corrosion, gummed, wearing and tearing, broken teeth etc.At this time just need to change the bad gear of point to ensure that machine runs well.Traditional integral gear needs axle to disassemble, then by gear shaft to dismounting, inevitably just need a large amount of associated components to disassemble, this dismounting and the process re-assemblied extremely bother, and replacing construction is longer, has a strong impact on manufacturing efficiency simultaneously.
Summary of the invention
The utility model provides a kind of novel magnetic gear, be mainly used in mechanical transmission, the utility model is provided with one week wedge shape gear teeth uniformly on wheel disc, side is provided with " work " font groove, be provided with permanent magnet in groove, the utility model is reasonable in design, easy to use, at tooth contact position, permanent magnet is housed, avoids the gear teeth because directly contacting the wearing and tearing caused, extending its working life.
For solving the problems of the technologies described above, the embodiment of the present application provides a kind of novel magnetic gear, comprise wheel disc, the gear teeth, rotating shaft, permanent magnet, groove formation, it is characterized in that, described wheel disc is provided with uniformly one week gear teeth, the gear teeth are wedge shape, side is provided with " work " font groove, are provided with permanent magnet in groove.
As the preferred embodiment of this programme, the described gear teeth are wedge shape, and major part is interior, and microcephaly is outside.
As the preferred embodiment of this programme, described groove is " work " font, and inside is provided with permanent magnet, and the shape of permanent magnet is identical with groove, is embedded in inside grooves.
As the preferred embodiment of this programme, described permanent magnet on each gear teeth to lay direction consistent, during with other engaged gears, on adjacent surface, the magnetic pole of permanent magnet is identical.
As the preferred embodiment of this programme, described wheel disc and the gear teeth are all nonmagnetic substance.
The one or more technological schemes provided in the embodiment of the present application, at least have following technique effect or advantage:
Reasonable in design, easy to use, at tooth contact position, permanent magnet is housed, avoids the gear teeth because directly contacting the wearing and tearing caused, extending its working life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the embodiment of the present application;
Fig. 2 is the structural representation after the gear teeth and permanent magnet combination;
In Fig. 1,1, wheel disc, 2, the gear teeth, 3, rotating shaft, 4, permanent magnet, 5, groove.
Embodiment
The utility model provides a kind of novel magnetic gear, is mainly used in mechanical transmission, and this design of gears is reasonable, easy to use, at tooth contact position, permanent magnet is housed, avoids the gear teeth because directly contacting the wearing and tearing caused, extending its working life.
In order to better understand technique scheme, below in conjunction with Figure of description and concrete mode of execution, technique scheme is described in detail.
As Figure 1-Figure 2, a kind of novel magnetic gear, comprises wheel disc 1, the gear teeth 2, rotating shaft 3, permanent magnet 4, groove 5 forms, it is characterized in that, described wheel disc 1 is provided with uniformly one week gear teeth 2, the gear teeth 2 are wedge shape, side is provided with " work " font groove 5, is provided with permanent magnet 4 in groove 5.
Wherein in actual applications, the described gear teeth 2 are wedge shape, and major part is interior, microcephaly is outside, can produce centrifugal force when gear rotates, this structure can alleviate the effect of centrifugal force to the gear teeth 2, namely alleviates the tensile stress between the gear teeth 4 and wheel disc 1, thus the probability that the reduction gear teeth 2 rupture from wheel disc 1, extend the life-span of gear.
Wherein in actual applications, described groove 5 is " work " font, inside is provided with permanent magnet 4, the shape of permanent magnet 4 is identical with groove 5, be embedded in groove 5 inner, permanent magnet 4 one aspect of " work " font increases soundness, is not easy to be thrown out of in groove 5, make the magnetic induction line of permanent magnet 4 present gradual change form diametrically on the other hand, increase magnetic force.
Wherein in actual applications, described permanent magnet 4 on each gear teeth 2 to lay direction consistent, during with other engaged gears, on adjacent surface, the magnetic pole of permanent magnet 4 is identical, owing to there is repulsive force between like pole, thus there is certain gap between two of the occlusion made gear teeth, reduce frictional force each other, thus make the gear teeth be not easy to be worn.
Wherein in actual applications, described wheel disc 1 and the gear teeth 2 are all nonmagnetic substance, and permanent magnet 4 is embedded in groove 5 inside simultaneously, and make its magnetic force in bond, wall impacts other magnetic components.
During use, two magnetic-gears are engaged, guarantee that the magnetic pole of permanent magnet 4 on the gear teeth 2 opposing side is identical, by the repulsive force between same pole, make to there is certain gap between two gear teeth 2, reduce friction each other, magnetic force increases the rotating speed of gear simultaneously, reduces power consumption.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
