Detailed description of the invention
In order to technical characteristic of the present utility model, purpose and effect are more clearly understood from, now comparison accompanying drawing describes detailed description of the invention of the present utility model in detail.
As shown in Figure 1 to Figure 3, the gear 1 in one preferred embodiment of this utility model includes circular body 11 and is distributed in the teeth 12 of circular body 11 outer ring.The center of circular body 11 is provided with rotation hole 13, and the one side of circular body 11 is provided with the boss 14 of the axis centre symmetry of two opposed gear 1.The another side of circular body 11 is provided with at least one pair of first counterbore 15, and the axis centre of every pair of first counterbore 15 opposed gear 1 is symmetrical.Boss 14 is identical to the distance at rotation hole 13 center with the first counterbore 15 to the distance at rotation hole 13 center, and the profile of boss 14 is corresponding with the first counterbore 15.
As shown in Figure 4, the gear 1 of this structure only arranges boss 14 in side, can two gear 1 stackings be arranged, the boss 14 of each gear 1 is arranged in the same direction, and the boss 14 of a gear 1 snaps onto in the first counterbore 15 of another gear 1, form a gear train, it is achieved quick-assembling.Gear 1 is generally injection mo(u)lding, as shown in Fig. 6 to Figure 12, in second embodiment of the present utility model, the 3rd embodiment, profile size, the number of teeth, thickness can design production as required, when fixing in the position that guarantee boss the 14, first counterbore 15 relatively rotates center, hole 13, the gear of various overall dimensions all can realize stacking.The profile size of two gears 1 of stacking, the number of teeth can be identical or different, when building robot, realize gear 1 transmission of specific gear ratio after stacking assembly, and the gear train after assembling also can increase the intensity of entirety.As shown in figure 13, boss 14 also can be placed on the same side by gear, it is achieved meshed transmission gear.
As it is shown on figure 3, rotation hole 13 is include two sections of different shoulder holes of diameter, locking after the locking parts such as bolt can be facilitated to wear, step can be used to accommodating nut etc..
The quantity of the first counterbore 15 can be one or more pairs of, and the gear 1 for stacking can remain to stacking assembly when circumferentially rotating.Each boss 14 and first counterbore 15 are arranged concentrically, and convenient when stacking is arranged, circumferentially opposed rotation will not occur at other positions, each gear 1 can be allowed to keep other the position such as teeth 12, hole corresponding, form an entirety.
Further, boss 14 is provided with and axially penetrates through the through hole 141 connected with the first counterbore 15, facilitates the molding of boss 14, it addition, when boss 14 snaps in the first counterbore 15, facilitate the gas overflowing in the first counterbore 15.When being relatively large in diameter of gear 1, the first counterbore 15 also can be that matrix form or centrosymmetry are arranged in circular body 11, convenient is connected with other parts.
At least one side of circular body 11 is provided with the butting section 16 of one end end face axially exceeding teeth 12 correspondence, and when two equivalently-sized gear 1 stackings are arranged, butting section 16 can make formation gap between teeth 12, is conveniently separated by two gears 1.Preferably, it is equipped with butting section 16 in the two opposite sides of circular body 11, when gear 1 is by not homonymy stacking, all can guarantee that formation gap between the teeth 12 of adjacent gear 1.Butting section 16 is by the side integrated convex of circular body 11, it is simple to molding.Certainly, in other embodiments, the axial two ends of teeth 12 have at least one end end face not exceed the side of circular body 11, are naturally formed gap after stacking, conveniently by the gear 1 of stacking separately.
As shown in Figure 1 and Figure 2, further, circular body 11 is provided with two the second counterbores 17 of the axis centre symmetry of opposed gear 1 in the side at boss 14 place, the profile of boss 14 is corresponding with the second counterbore 17, and the second counterbore 17 is identical with the distance of boss 14 to rotation hole 13 center to the distance at rotation hole 13 center.Further, the line of centres of two boss 14 is vertical with the line of centres of two the second counterbores 17, it is possible in angle, facilitates boss 14 to be inserted into the second counterbore 17 of another gear.In certain embodiments, centered by the quantity of the first counterbore 15 and the second counterbore 17 symmetrical multiple time, the second counterbore 17 connect confession bolt etc. by the wheel gear locking of stacking, lifting intensity with the first counterbore 15.Certainly, it is possible to be separately provided lockhole in other positions by the wheel gear locking of stacking.
Corresponding, as it is shown in figure 5, in certain embodiments, gear train also includes the gear 1 that at least two stacking is arranged, the boss 14 having two gears 1 is oppositely arranged, and boss 14 circumferential misalignment of these two gears 1 is arranged, and is respectively clamped in the second counterbore 17 of gear 1 corresponding thereto.This stacking set-up mode, can make boss 14 mutually to stash, and will not take the space of outside, and the space making splicing robot can be compacter.
Certainly, when there being three or more gear 1 stackings to arrange, it may include boss 14 is oppositely arranged and arranges two kinds of situations in the same direction.When there being two gears 1 of boss 14 reverse stack, the boss 14 of one gear 1 is snapped onto in the first counterbore 15 of one of them gear 1, in the case can combination in any, composition thickness thicker, the corresponding assemblies such as intensity is bigger, the gear shaft of the multiple transmission number of teeth.In actual assembled, the boss 14 of gear 1 also can snap onto on the through hole of other correspondences of other gears 1, it is possible to snaps onto on other through holes of toy platform part, plays the effect of location.
It is to be appreciated that above-mentioned each technical characteristic can use and unrestricted in any combination.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
