Detailed description of the invention
Referring to the example structure selected by the present invention shown in Fig. 1 to Fig. 6, figure, this is intended for purposes of discussion, not by the restriction of this kind of structure in patent application.
The present embodiment provides a kind of hollow type motor module, as it is shown in figure 1, with a motor 1 in conjunction with a reductor 2.As shown in Figure 2 to Figure 3, motor 1 includes outer layer stator 11, the first rotor 12 and plural second rotor 13, the first rotor 12 is provided with first coil 121 in periphery and is located in outer layer stator 11, plural number the second rotor 13 is respectively provided with the second coil 131 in periphery and is respectively provided in the first rotor 12, and each second rotor 13 has the axis part 132 stretching out the first rotor 12, reductor 2 is connected with the axis part 132 of plural second rotor 13.It is excitatory with first coil 121 and drive the first rotor 12 to rotate that outer layer stator 11 is provided with plural first Magnet 111, and it is excitatory with the second corresponding coil 131 and drive plural second rotor 13 synchronous rotary that corresponding each second rotor 13 of the first rotor 12 is provided with plural second Magnet 122.Motor 2 has one first hollow bulb 14 in the first rotor 12.
As shown in Figure 4, a rotating seat 21 it is provided with in the reductor 2 of the present embodiment, what this rotating seat 21 hollow and peripheral cyclic in the axle center of its rotation were arranged with that plural number can be pivoted relative to each other turns tooth 22, and reductor 2 interior tool the first ring gear 23 turns tooth 22 in rotating seat 21 periphery with plural number with internal tooth 231 and engages, the axis part 132 of plural number the second rotor 13 is connected to plural number and turns the axle center of tooth 22, the first rotor 12 and plural second rotor 13 are all by excitatory and rotate, so that rotation that seat 21 for the first order slow down is rotated.As shown in Figure 5, internal structure seen by turnback is turned over for the reductor 2 shown in Fig. 4, visible rotating seat 21 is stretched the axle portion 211 of the synchronous axial system set, this axle portion 211 is provided with central gear 24, plural number planetary gear 25 engages with central gear 24 in the surrounding of central gear 24, and tool the second ring gear 26 engages with plural number planetary gear 25 with internal tooth 261 in the surrounding of plural number planetary gear 25 in reductor 2, central gear 24 rotates with rotating seat 21 in axle portion 211, plural number planetary gear 25 driven by central gear 24 and be the second level slow down rotation.Rotating seat 21 has one second hollow bulb 212, in motor 1 and reductor 2 groups in conjunction with time, the first hollow bulb 14 communicates with the second hollow bulb 212, for wire rod wear layout use.
By above-mentioned explanation it is seen that it is an advantage of the current invention that, when the motor 1 of the present invention rotates with the first rotor 12 opposed outer layer stator 11, second rotor 13 rotates relative to the first rotor 12 again, when the first rotor 12 and plural second rotor 13 all by excitatory and when rotating, tooth 22 is turned because the axis part of plural second rotor 13 connects, therefore turn tooth 22 and be driven in rotation and seat 21 be rotated and rotate, plural number planetary gear 25 is driven to rotate again through the central gear 24 set by axle portion 211, therefore under the structure that motor 1 has the first rotor 12 and the second rotor 13, reductor is only connected with the axis part 132 of the second rotor 13 turning tooth 22, seat 21 can be rotated rotate, plural number planetary gear 92 need not must be driven with the central gear 93 of leading portion such as conventional motor module, plural number planetary gear is driven again by the central gear of the train of reduction gears of back segment, therefore only a central gear 24 can reach two sections of effects slowed down.
Certainly, the present invention still suffers from many examples, therebetween the only change in details.Referring to Fig. 6, it is the second embodiment of the present invention, wherein, with the structure that first embodiment major difference is that reductor.The reductor 3 of the present embodiment is provided with one first ring gear 31, this first ring gear 31 engages plural first gear 32 with internal tooth, each first gear 32 engages one second gear 33, the axis part 132 of plural number the second rotor 13 is connected to each second gear 33, and this partly belongs to the train of reduction gears of the present embodiment leading portion.Reductor 3 also has the train of reduction gears (not shown) of back segment, first ring gear 31 is in conjunction with an output shaft, this output shaft is provided with a central gear, reductor 3 is in the plural planetary gear engaged with central gear that is provided around of output shaft, the internal tooth of the second ring gear that plural planetary periphery engagement one is combined with the first ring gear 31；Drive the first ring gear 31 to rotate by first and second gear 32,33 to slow down for the first order, and driven the second ring gear by the first ring gear 31, and being driven this output shaft rotation by the second ring gear driving plural number planetary gear is slow down in the second level.
Slow down for the first order it follows that drive the first ring gear 31 to rotate by first and second gear 32,33, and driven the second ring gear by the first ring gear 31, and being driven output shaft 21 to rotate by the second ring gear driving plural number planetary gear 23 is slow down in the second level.
The reductor 3 of the present embodiment, for a kind of conventional reductor, in what this was intended to be illustrated it is, the motor 1 of the present invention except providing primary speed-down and except the application that reductor 2 is combined in first embodiment, if meet reductor 3 (the namely conventional reductor) of the present embodiment, the first rotor 12 can be controlled as maintaining static by motor 1, its function is namely such as stator one dish, and only the second rotor 13 rotates, it can thus be appreciated that the motor of the present invention also can be useful in conventional reductor and as drive source.
The announcement of embodiment described above is in order to illustrate the present invention, and is not used to the restriction present invention, therefore the change of numerical value or the displacement of equivalence element must be subordinate to scope of the invention such as.
By detailed description above, those skilled in the art can be made to understand, and the present invention can reach object defined above really, and the real regulation having met Patent Law, so proposing patent application.
