Fig. 1 is the structural drawing of the embodiment of the present invention;
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment:
Embodiment:
as shown in fig. 1, a kind of reducing gear of starter comprises input shaft 1, joiner 3, output shaft 4 is provided with input gear 21 between input shaft 1 and output shaft 4, connect gear 22, output gear 23, public output planetary frame 24, the second input gear 25, conjugation tooth ring 26, the second output gear 27, common carrier 28, planetary pinion 29, input gear 21 connects with input shaft 1, and by planetary pinion 29 and public output planetary frame 24 on public output planetary frame 24, connect gear 22 and connect, connect another group planetary pinion 29 and public output planetary frame 24 that gear 22 passes through public output planetary frame 24 again, output gear 23 connects, and output gear 23 connects with the second input gear 25, and the second input gear 25 is by planetary pinion 29 and common carrier 28 on common carrier 28, conjugation tooth ring 26 connects, and conjugation tooth ring 26 is again by another group planetary pinion 29 and common carrier 28 on common carrier 28, the second output gear 27 connects, and the second output gear 27 connects with the present invention's some elements in addition, and common carrier 28 connects with input gear 21 by joiner 3 again, and 24, public output planetary frame connects with output shaft 4.
Described joiner 3 is selected overrunning clutch.
Each road power of the present invention is all unidirectional delivery, input gear 21 is divided into two-way to input power by the planetary pinion 29 on public output planetary frame 24, one the road flows into public output planetary frame 24, another road flows into and connects gear 22, split into two-way by another group planetary pinion 29 on public output planetary frame 24 again, one the road flows into public output planetary frame 24, and another road flows into output gear 23.
because the rotating speed relations of distribution between above-mentioned each element can change, two-way power stream will change according to the variation of rotating speed distribution between the two, when public output planetary frame 24 rotating speeds are zero, its input power is zero, but moment is non-vanishing, at this moment, the input power that connects gear 22 changes to maximum value by certain value, described certain value refers to when the rotating speed that connects gear 22 and public output planetary frame 24 is identical, both press the value that the planet row torque ratio distributes the input power gained, described maximum value refers to the total output of motor input, that is to say, when two-way power changes, connect gear 22 and will play the bending moment effect, its moment that is delivered on public output planetary frame 24 and output shaft 4 is also changed thereupon.
the input power of direct current motor splits into two-way through input gear 21, one the road flows into public output planetary frame 24, another road flows into and connects gear 22, this power dividing is two-way, one the road flows into public output planetary frame 24, another road flows into output gear 23, flow into again the second input gear 25, it splits into two-way again, one the road flows into common carrier 28, another road flows into conjugation tooth ring 26, this power splits into two-way again, one the road flows into common carrier 28, another road second output gear 27 flows into the some element works done beyond the present invention, wherein, common carrier 28 these power of one tunnel flow into input gear 21 by joiner 3, conflux with the input power of direct current motor, and repeat above-mentioned shunting process, public output planetary frame 24 these power of one tunnel are delivered to output shaft 4, thereby realized the power of direct current motor is externally exported by output shaft 4.
For the present invention, when the rotating speed of input shaft 1 constant, moment of torsion on output shaft 4 changes with the variation of its rotating speed, rotating speed is lower, the moment of torsion of output shaft 4 is larger, otherwise, less, thereby realize that the present invention can with the difference of engine start resistance, change the reducing gear of a kind of starter of moment automatically.
when the present invention uses, if the input power of direct current motor, input speed and load constant, the rotating speed and the moment of torsion that are input shaft 1 are constant, before engine start, the rotating speed of output shaft 4 is zero, when direct current motor starts, because of output shaft 4 transfixions, be public output planetary frame 24 transfixions, the power of direct current motor all flows into and connects gear 22, make moment of torsion after its bending moment greater than the input torque of direct current motor, and split into two-way, one the road flows into public output planetary frame 24, because of its transfixion, power all flows into output gear 23, flow into again the second input gear 25, this power splits into two-way again, one the road flows into common carrier 28, another road flows into conjugation tooth ring 26, this power splits into two-way again, one the road flows into common carrier 28, another road second output gear 27 flows into the some element works done beyond the present invention, wherein, public output planetary frame 24 these power of one tunnel are delivered to output shaft 4, and common carrier 28 these power of one tunnel flow into input gear 21 by joiner 3, realize converging with the input torque of direct current motor, and repeat above-mentioned shunting process, constantly divide square between each element, the iterative cycles of bending moment and remittance square, the moment of torsion that is delivered to public output planetary frame 24 is constantly increased, and be delivered to output shaft 4, when the moment of torsion that is delivered on output shaft 4, after all parts, when finally being enough to overcome starting resistance, engine start also begins to accelerate, at this moment, the rotating speed of public output planetary frame 24 also increases from zero gradually gradually, at this moment, power is divided into two-way, flowing into the power that connects gear 22 reduces gradually, thereby its square effect that increases is reduced gradually, the moment of torsion of output shaft 4 reduces along with the increase of rotating speed, when the rotating speed of input shaft 4 and input gear 21 is identical, connection gear 22 does not recur and increases the square effect.
