Its reduction speed ratio calculates:
The described star speed reducer that spreads out is divided into two-layer, and first layer uses few teeth difference to slow down, and the second layer is similar to planetary speed reducer, is just cancelled by sun wheel, is engaged by a plurality of planet wheels that heteromorphic teeth drives with internal gear; Because have two-layer, each layer deceleration principle is different, therefore separately illustrates:
Definition:
The internal gear number of teeth is A, and the planet wheel number of teeth is B, and in heteromorphic teeth, the number of teeth of teeth portion is C, and C is greater than B;
First layer: few teeth difference ways of deceleration
Reduction speed ratio (1)=moving runner number of teeth/tooth difference=B/ (B-C);

The second layer: planet wheel engages with internal gear and slows down
Reduction speed ratio (2)=A/B;
The star speed reducer planet carrier that spreads out exports reduction speed ratio:
Spread out star reduction speed ratio=[B/ (B-C)] * [A/B]+1
=A/ (B-C)+1--(1) formula
Planetary reduction gear ratio=A/ sun tooth number+1--contrasts formula
Above two formula contrasts can be found, as long as it is poor that the positive tooth number in contrast formula is replaced by the tooth of planet wheel and heteromorphic teeth, namely form (1) formula; Because positive tooth number is generally not less than 13, and tooth difference minimum can be 1, star reduction speed ratio of therefore spreading out significantly will improve than conventional planetary reduction speed ratio.
The star speed reducer internal gear that spreads out exports reduction speed ratio:

Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
According to this form of star speed reducer heteromorphic teeth of spreading out, interior ring structure 21 form can be divided into, structure 22 form is cut down in outside and structure 23 form three kinds is cut down in inner side.
[embodiment one]
With reference to shown in Fig. 1 and Fig. 2, when heteromorphic teeth is interior ring structure 21 form, planet wheel 3 and the gears meshing schematic diagram between heteromorphic teeth 2 and internal gear 4, this structure can obtain total number of teeth in engagement and maximize, and is applicable to high pulling torque and exports.Planet carrier output and internal gear can be divided into export two kinds according to the way of output.
With reference to shown in Fig. 3, in order to spread out, star speed reducer planet carrier exports, and this star speed reducer that spreads out comprises input shaft 1, heteromorphic teeth 2, a plurality of planet wheel 3, internal gear 4, casing 5, clutch shaft bearing 6, base plate 7,1 second bearing 8, the 3rd bearing 8' and a top cover 9.
Casing 5, this casing 5 inside is provided with containing space, is provided with this input shaft 1, this heteromorphic teeth 2, this plurality of planet wheel 3, this internal gear 4, this clutch shaft bearing 6, this base plate 7, this second bearing 8, the 3rd bearing 8' and this top cover 9 in this containing space.
Input shaft 1, this input shaft 1 is crank structure, and its eccentric end is connected with this heteromorphic teeth 2 by this clutch shaft bearing 6, and it should be noted that this clutch shaft bearing 6 is important transmission part, Fig. 3 is for needle bearing.
Heteromorphic teeth 2, this heteromorphic teeth 2 is this interior ring structure 21 form, promotes and eccentric shifting movement by this input shaft 1.
A plurality of planet wheel 3, this plurality of planet wheel 3 its be highly two-layer, be arranged on circumferentially same uniformly, this heteromorphic teeth 2 that this plurality of planet wheel 3 is corresponding be provided with a plurality of interior teeth portion 211.The teeth of the teeth of planet wheel first layer and this interior teeth portion 211 are connected with a joggle, the number of teeth of planet wheel is less than the number of teeth of interior teeth portion 211, this interior ring structure can be set on planet wheel, form the gear engagement structure of first layer as shown in Figure 1, the quantity of this plurality of planet wheel 3 is consistent with the quantity of this plurality of interior ring structure of this heteromorphic teeth 2, and this plurality of interior ring structure is also evenly distributed on this plurality of planet wheel 3 to distribute circumferentially, namely ensure that this heteromorphic teeth 2 is when eccentric motion, this interior teeth portion 211 can engage with corresponding planet wheel simultaneously, make that this plurality of planet wheel 3 is promoted by this heteromorphic teeth 2 and rotation is rotated.
Base 7, this plurality of planet wheel 3 axle center is fixed on length on this base 7, on this base 7 a plurality of attachment post 71; Wherein, because this attachment post 71 a plurality of blocks this heteromorphic teeth 2 eccentric motion path, therefore offer a plurality of relief portion 212 between the adjacent interior teeth portion 211 of this heteromorphic teeth 2, to ensure this heteromorphic teeth 2 eccentric motion smoothly.
Top cover 9, this top cover 9 is locked on attachment post 71, forms planet carrier with this base 7, and this plurality of planet wheel 3 to be arranged in this planet carrier and to be merely able to keep rotation to rotate.
Internal gear 4, on the sheathed excircle being fixed on this plurality of planet wheel 3 of this internal gear 4, the teeth 41 of this internal gear 4 are connected with a joggle with the teeth of this plurality of planet wheel 3 second layer, because this internal gear 4 is fixed in this casing 5, this casing 5 keeps maintaining static, so this internal gear 4 also cannot rotate, when planet wheel generation time rotational, planet wheel rolls along this internal gear 4 inwall with this planet carrier whole, and namely this planet carrier forms outputting power.
