Embodiment
Referring to figs. 1 through Fig. 5; Fig. 1 to Fig. 5 is the structural representation of the utility model one specific embodiment; As shown in the figure; A kind of reducing gear of drive unit; Comprise the reducing gear main body 2 that is connected with drive motor 1 output shaft, reducing gear main body 2 comprises that first planetary gears 21 and second planetary gears, 22, the first planetary gears 21 comprise the first centre-driven gear 31, internal gear 4, first planetary gear set 41 and first planetary carrier 51 that is connected with drive motor 1 output shaft; First planetary gear set 41 is made up of three first planetary pinions 61; And be connected with the first centre-driven gear 31, internal gear 4 respectively, first planetary carrier 51 is provided with three groups of first planet pins 511 with 511, three groups of first planet pins of first planetary pinion, the 61 corresponding configurations of first planetary gear set 41 and is connected with the first corresponding planetary pinion 61 respectively.
As shown in the figure; Second planetary gears 21 comprises the second centre-driven gear 32, second planetary gear set 42 and second planetary carrier 52 that is arranged on first planetary carrier, 51 centers; Said second planetary gear set 42 is made up of four second planetary pinions 62; And be connected with the second centre-driven gear 32, internal gear 4 respectively; Second planetary carrier 52 is provided with four groups of second planet pins 521 with second planetary pinion, the 62 corresponding configurations of second planetary gear set 42; Four groups second planet pin 521 is connected with the second corresponding planetary pinion 62 respectively, and the low speed output shaft 7 of reducing gear main body 2 is arranged in second planetary carrier 52 in the heart.
As shown in the figure, drive motor 1 is fixed on reducing gear main body 2 lower ends through motor mount 11, and reducing gear main body 2 upper ends dispose upper end cap 12, and low speed output shaft 7 passes upper end cap 12, and through upper end cap 12 stationary positioned.
Further, reducing gear main body 2 also disposes scaffold 8, and scaffold 8 is fixed on the upper end cap 12, and scaffold 8 is provided with some mounting holes, and reducing gear main body 2 can be installed in the position of required installation through scaffold 8.
During drive motor 1 energising, the output shaft of drive motor 1 drives the first centre-driven gear 31 and rotates, and first planetary gear set 41 that is connected with the first centre-driven gear 31, internal gear 4 respectively is under the driving of the first centre-driven gear 31; Three first planetary pinions 61 of first planetary gear set 41 rotate around the rotating shaft of the first centre-driven gear 31; And drive 51 rotations of first planetary carrier, and at this moment accomplish the deceleration of the first order, the second centre-driven gear 32 that is arranged on first planetary carrier, 51 centers rotates with first planetary carrier 51; Four second planetary pinions 62 that drive second planetary gear set 42 rotate around the rotating shaft of the second centre-driven gear 32; And drive 52 rotations of second planetary carrier, thus the low speed output shaft 7 that drives reducing gear main body 2 rotates output, and low speed output shaft 7 is connected with the drive unit of mechanisms such as door, window, awning, advertising signboard, curtain; Thereby realize the driving of these mechanisms; Owing to adopted the planetary pinion transmission, made that the volume of the utility model is less, cost is low, easy hidden installation and easy for installation; And the planetary pinion transmission has, and velocity ratio is big, bearing capacity big, the stable transmission characteristics; When motion of mechanism such as driving gate, window, awning, advertising signboard, curtain, steadily reliable, and can drive large corporation.
Fig. 5 is the structural representation of the utility model when being applied to out the paulin device, and as shown in the figure, two groups drive motor 1, reducing gear main body 2 are installed on out respectively in the motor cabinet 92 of paulin device; The low speed output shaft 7 of reducing gear main body 2 is connected with the input shaft of the switching-over driving mechanism 91 of driving the paulin device; Drive reducing gear main body 2 through drive motor 1, drive and open the action of paulin device, the unlatching that realizes awning with fold; Because the volume of the utility model is less; Can effectively reduce out the volume of paulin device, and can steadily move, driving force is big.
More than the preferable enforcement of the utility model is specified; Certainly; The utility model can also adopt the form different with above-mentioned mode of execution; For example reducing gear main body 2 can be provided with one group or many group planetary gears according to the needs of transmission, and the planetary pinion of planetary gear set also can dispose one or more according to design demand; So those of ordinary skill in the art should belong in the protection domain of the utility model conversion of under the prerequisite of spirit of the present invention, being done that is equal to or corresponding the change.
