Below, each example of the present invention is elaborated.At first, with reference to annex map 1～Fig. 4, the 1st example of the present invention is described.The slewing gear 1 that the 1st example is relevant is to be used and vibrative a kind of shake unit 3 above the mobile phone etc., when receiving signal.
This shake unit 3 has shell 5, remains in motor 7 and eccentric hammer 9 in the shell 5 like Fig. 2 and shown in Figure 3.
Casing 5 is divided into front side 5a of casing portion and the rear side casing 5b of portion, and these chimeric fixing backs are formed ring-type casing 5.
On the front panel 11 of casing 5, be set side by side with 2 bearing 13a, 13b, even if with front panel relatively to rear sidewall 15 on also be provided with bearing 17a, 17b.
Motor 7 has motor body 19 and motor drive shaft 21.After motor drive shaft 21 is pressed into and is installed in the motor body 19.
Each front side end of motor drive shaft 21 and hammer axle 23 and rear side end are moved respectively that to remain in bearing 13a, 13b, 17a, 17b last comfortablely.
In addition, on each front side end and rear side end of motor drive shaft 21 and hammer axle 23, be respectively arranged with the slewing gear 1 of this example, the revolution of motor drive shaft 21 is passed on hammer axle 23.
Each slewing gear 1 of front side and rear side is identical formation, so after front side slewing gear 1 described, about the rear side slewing gear, slewing gear same function effect part in front side is then attached with same-sign, omits its detailed description.Driving gear 25 is fixed on the motor drive shaft 21, and driving gear 25 is revolution together along with the revolution of motor drive shaft 21.Driven gear 27 is fixed on the hammer axle 23, and is mutually meshing with driving gear 25.In addition, in Fig. 2, what symbol 29 was represented is pad.
Such shown in (c) like Fig. 1 (b), driving gear 25 and driven gear 27 are made by the magnetite material, are magnetized into the S utmost point and the N utmost point respectively.With a side 31 of gear 25,27 as the N utmost point, with another side 32 as the S utmost point.Therefore, the tooth 35 of each gear 25,27 also is the same, with the one of which side as the N utmost point, with its opposite side as the S utmost point.
That kind as shown in Figure 4, homopolarity relative status under tooth 35,35 spaces of these gears 25,27 and the meshing state.Promptly in the tooth 35,35 of each other meshing gear 25,27, between the N utmost point relatively to, between the S utmost point relatively to.
In the slewing gear 1 of this example, driving gear 25 and driven gear 27 in mutually meshing tooth 35,35, same pole, promptly the N utmost point and the N utmost point, the S utmost point and S extremely relatively to, and since magnetic pole identical make mutual between repulsion mutually.
Next, effect and the effect to the shake unit 3 of relevant example of the present invention describes.
Since the driving of motor body 1, motor drive shaft 21 revolution in a single day, and the driving gear 25 that then is fixed on the motor drive shaft 21 will turn round.Meshing after 27 revolutions of the driven gear on the driving gear 25, according to the revolution of hammer axle 23, eccentric hammer 9 revolutions produce vibration.At this moment, as shown in Figure 4, driving gear 25 is in case revolution and since the tooth 35 of the tooth 35 of driving gear 25 and driven gear 27 be with magnetic pole relatively to.So because the repulsive interaction of magnetic force, the tooth 35 of driving gear 25 and the tooth 35 of driven gear 27 be contactless state, also or be the turn state after contacting.
According to this example, driving gear 25 and driven gear 27 are just passable as long as on its axle direction one side and another side, form different magnetic poles.So, magnetize according to a direction of making different magnetic poles in gear one side and another side because make feasible, so need not to adopt special magnetizer, simple in structure and magnetize easily.In view of the above, can provide the cheap slewing gear of manufacturing price 1.
In the meshing each other tooth 35,35 of the driving gear 25 of slewing gear 1 and driven gear 27; Because the part of subtend is a same pole; So the repulsive interaction according to mutual magnetite is in contactless state, even if at contact condition; Can reduce the contact of tooth 35,35 and press, the abrasion that can reduce driving gear 25 and driven gear 27 with contact sound.
In the shake unit 3 of this example, eccentric hammer 9 is because motor body 19 is slightly identical with length dimension than length direction.So, for motor body 19, after increasing, eccentric hammer 9 can obtain more multi-eccentric amount, can access bigger vibration so compare in the past.
Because the length of eccentric hammer 9 and corresponding hammer axle 23 can extend, so, can obtain the riveted size of sufficient eccentric hammer 9, can eccentric hammer 9 firmly be fixed in and hammer into shape on spools 23.In addition, the riveted position of eccentric hammer 9 can be got fixed arbitrarily, so design freedom is higher.Because motor 7 and eccentric hammer 9 are accommodated in the casing 5, so the eccentric hammer 9 in preventing to turn round can touch its periphery other zero device or portion's material.
Below, other example of the present invention is described, in the example of following explanation, then attach for the part that plays the same function effect with above-mentioned example and to omit its explanation with same-sign.Below main being noted that and above-mentioned example different portions.
Explain with reference to 5 pairs of the 2nd examples of the present invention of figure.In this 2nd example, each tooth 35,35 that driving gear 25 and driven gear 27 will be formed at respectively on the periphery is made same pole, and promptly interior all sidepieces of each gear 25,27 are made the magnetic pole different with tooth 35,35.In this example, tooth 35,35 is the S utmost point, and interior all sidepieces are the N utmost point.
In this 2nd example; Because each meshing tooth 35,35 of driving gear 25 and driven gear 27 are each other made same pole; Effect according to mutual repulsion magnetic pole; Even if each tooth 35,35 of driving gear 25 and driven gear 27 is pressed in the contact that contact condition also can reduce tooth 35,35 for non-contact contact, the abrasion that also can reduce driving gear 25 and driven gear 27 with contact sound.

Driving wheel 51 is identical formation with follower 53, is to be made up of nonmagnetic material base material 41 and 45 of magnetites.As shown in Figure 7, base material 41 is a cylindrical shape, uniformly-spaced is formed with a plurality of with the through hole 43 of parallel axes along Zhou Fangxiang.In this example, each through hole 43 is a cylindrical shape.
According to this 3rd example, driving wheel 51 revolution in a single day, follower 53 is owing to the repulsive interaction of magnetic pole then can chase after from revolution.
According to this 3rd example,, can play and the 1st example same function effect except above-mentioned the 1st example meshing.That is because the 3rd example, the part of driving wheel 51 and follower 53 mutual subtends since the repulsion of different magnetic poles and can chase after from, in the contactless state turning down, so just do not wear and tear and contact sound.
Driving wheel 51 and follower 53 are inserted into magnetites 45 such as existing bar-shaped or rib shape in the patchhole 43 that is formed in the base material 41, and manufacturing is easier to.
In addition, in the manufacturing of driving wheel 51 and follower 53, can adopt general magnetite, need not to use special magnetizer just can make, can provide manufacture cost cheap slewing gear.
The invention is not restricted to above-mentioned example, only otherwise break away from the scope of main idea of the present invention, can do all distortion maybe.Such as, slewing gear 1 of the present invention is to be the explanation that example is carried out with shake unit 3, but be not limited thereto, and is used for transmission rotary motive power aspect in this way, does not then have special purposes restriction.
In the 3rd example, the shape that is formed at through hole 43 and magnetite 45 in the base material 41 is as shown in Figure 8, also can be four jiaos of prism shapes such as prism, does not limit its shape.
In the 3rd example, magnetite 45 also can be made the outer circumferential face that is exposed to driving wheel 51 and follower 53.
As shown in Figure 9, driving wheel 51 also can be configured to the state of contacting with follower 53.Add the repulsive force of magnetite, the frictional force of driving wheel 51 and follower 53 also can work, so will improve to the following of the driving wheel 51 of follower 53.In this variation, on driving wheel 51 and follower 53, be designed with the top layer 55 that the polyurethane of wear resistance performance resin is processed, the abrasion that contact is brought have the effect of life-saving.
Further, shown in figure 10, can also be in variation shown in Figure 9, relatively to magnetic pole be different magnetic poles, according to mutual tractive force effect, chase after from driving wheel 51, follower 53 revolutions drive.
In addition, in the 3rd example shown in Fig. 6, can also be shown in figure 11, relatively to magnetic pole as different magnetic poles because the mutual magnetic force of traction, chase after from driving wheel 51, follower 53 revolutions drive.
