Description
Technical field
The utility model relates to a kind of harmonic gear reducer, especially a kind of magnetic force harmonic gear reducer.
Background technique
Harmonic driving has that velocity ratio is large, precision is high, bearing capacity is large, volume is little, lightweight, transmission efficiency is high, stable drive, noise are little, can, to advantages such as confined space transmission campaigns, apply more and more extensive in recent years.Carry out in the sporting flying process that harmonic wave drive speed reducer is equipped at flight carrier etc. in pose adjustment, the subsystem that automatically to control etc., play an important role, having become must obligato critical elements.
Fig. 1 shows a kind of common harmonic wave drive speed reducer, and the core members of harmonic wave drive speed reducer is flexbile gear 3, steel wheel 4 and wave-generator 1, is commonly called as three-major-items.Flexbile gear 3 is arranged on the periphery of wave-generator 1, with external toothing 3a on it.And steel wheel 4 is arranged on the periphery of flexbile gear, in it, be provided with ring gear 4a.And the inside and outside gear ring part engagement on steel wheel 4 and flexbile gear 3.During transmission, wave-generator 1 forces flexbile gear to produce resiliently deformable, and the tooth at its major axis two ends is engaged completely with the tooth of steel wheel, and the tooth at minor axis two ends departs from completely, and the tooth between major and minor axis is then in the transition state of half engagement.When wave-generator 1 rotates, along with the change of flexbile gear 3 deformation place, between flexbile gear 3 and steel wheel 4 gear teeth, by engaging-in, engage, nibble out, the change of disengaging order, thus making flexbile gear 1 relative to steel wheel 2 slow rotation, sense of rotation is contrary with turning to of wave-generator 3.
But in existing harmonic gear reducer, structure all more complicated of its wave-generator 1, and fabricating cost is higher.
Model utility content
The utility model object is: for the problems referred to above, provide a kind of structure simple, with low cost and be easy to produce magnetic force harmonic gear reducer.
The technical solution of the utility model is: a kind of magnetic force harmonic gear reducer, comprise the wave-generator of ellipsoidal structure, be set in described wave-generator outer and with the flexbile gear of external toothing, be positioned at described flexbile gear peripheral and with the steel wheel of ring gear, described external toothing engages with described ring gear part, described steel wheel is provided with alternating magnetic field generating means, described alternating magnetic field generating means can produce the alternating magnetic field that S pole and N pole are along the circumferential direction constantly rotated, described wave-generator is the magnet that two ends are respectively S pole and N pole, and the end face at these magnet two ends is smooth surface.
The end face at described magnet two ends is arc smooth surface.
Also comprise casing, described wave-generator, flexbile gear and steel wheel are arranged in this casing internal.
Described wave-generator is preferably permanent magnet.
The utility model has the advantages that:
1, compact structure, volume are little, lightweight, and fabricating cost is low.
2, velocity ratio is large, scope is wide.
3, the number of teeth simultaneously engaged is many, bearing capacity and anti-overload ability strong.
4, the motion state of engagement pair is for rolling, and working pressure angle is less than the working pressure angle of involute one tooth Planetary Gear Transmission, alleviates the load of rotary arm bearing, improves transmission efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme of the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, 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 conventional harmonic gear reducer;
Fig. 2 is the structural representation of magnetic force harmonic gear reducer in the utility model embodiment;
Wherein: 1-wave-generator, 2-casing, 3-flexbile gear, 3a-external toothing, 4-steel wheel, 4a-ring gear.
Embodiment
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that this embodiment is not limited to for illustration of the utility model limit scope of the present utility model.The implementation condition adopted in embodiment can do further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.
Fig. 2 shows a specific embodiment of this magnetic force harmonic gear reducer of the utility model, identical with conventional harmonic gear reducer is, its also comprise ellipsoidal structure wave-generator 1, be set in described wave-generator outer and with external toothing 3a flexbile gear 3, be positioned at that described flexbile gear 3 is peripheral and with the steel wheel 4 of ring gear 4a, described external toothing 3a partly engages with described ring gear 4a.
The key improvements of the present embodiment is: described steel wheel 4 is provided with alternating magnetic field generating means, described alternating magnetic field generating means can produce the alternating magnetic field that S pole and N pole are along the circumferential direction constantly rotated, described wave-generator 1 is the magnet that two ends are respectively S pole and N pole, and the end face at these magnet two ends is smooth surface.Described wave-generator is preferably permanent magnet.
Refer again to shown in Fig. 2, during work, just as Principle of Electric Engine, the N pole of the alternating magnetic field that described alternating magnetic field generating means produces and S pole, constantly change is rotated in fig. 2 along counterclockwise circular direction, this alternating magnetic field also constantly changes the magnetic pull direction that the wave-generator 1 be made up of magnet produces, the rotation that this gravitation drives magnet wave-generator 1 also to do counterclockwise circular direction is in fig. 2 rotated, thus drive flexbile gear 3 to be out of shape, along with the change of flexbile gear 3 deformation place, between flexbile gear 3 and steel wheel 4 gear teeth, by engaging-in, engagement, nibble out, the change of disengaging order, thus make flexbile gear 1 make clockwise slow rotation in fig. 2 relative to steel wheel 2, sense of rotation is contrary with turning to of wave-generator 3.
In this example, the end face at wave-generator 1 two ends of being made up of magnet is arc smooth surface, so ensures that wave-generator 1 can rotate reposefully smoothly in flexbile gear 3.
This retarder also comprises casing 2, and described wave-generator 1, flexbile gear 3 and steel wheel 4 are arranged in this casing internal.
Certainly, above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to people can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
