Embodiment 1:
The present embodiment provides a kind of little inertia clutch, gear, as shown in Figure 1, comprise driving shaft 1 and driven shaft 2, described driving shaft 1 is fixed with two driving gears, be respectively the first driving gear 3 and the second driving gear 4, driving shaft 1 and two driving gear composition gear shafts; On described driven shaft 2, movable sheath has two driven gears, be respectively the first driven gear 5 and the second driven gear 6, first driven gear 5 and the second driven gear 6 engage with the first driving gear 3 and the second driving gear 4 respectively, and a free-sliding spline cover 7 is equipped with in the position on described driven shaft 2 between two driven gears.
The outside two ends of free-sliding spline cover 7 are respectively equipped with external toothing, and the lower end surface of the first described driven gear 5 and the upper-end surface of the second driven gear 6 are respectively equipped with the ring gear that the external toothing that can overlap 7 with free-sliding spline engages.
In this structure of the present embodiment, free-sliding spline cover 7 is in different positions, just has different deceleration results and occurs, if the velocity ratio between the first driven gear 5 and the first driving gear 3 is i
1, the velocity ratio of the second driven gear 6 and the second driving gear 4 is i
2, the velocity ratio between free-sliding spline cover 7 and the first driven gear 5 is i
3, the velocity ratio between free-sliding spline cover 7 and the second driven gear 6 is i
4,
.
Free-sliding spline cover 7 will have three gears, for not being: the position of free-sliding spline cover 7 when engaging with the first driven gear 5, free-sliding spline are overlapped 7 positions when engaging with the second driven gear 6 and free-sliding spline and overlapped 7 and mediate, position when not engaging with both.
When free-sliding spline cover 7 is in the position of engaging with the first driven gear 5, now, second driving gear 4 and the second driven gear 6 dally, and transmission of power circuit is driving shaft 1, and------driven shaft 2, velocity ratio is the first driven gear 5---free-sliding spline cover 7---the first driving gear 3
;
When free-sliding spline cover 7 is in the position of engaging with the second driven gear 6, now, first driving gear 3 and the first driven gear 5 dally, and transmission of power circuit is driving shaft 1, and------driven shaft 2, velocity ratio is the second driven gear 6---free-sliding spline cover 7---the second driving gear 4
;
When free-sliding spline cover 7 mediates, now the first driving gear 3, first driven gear 5, second driving gear 4 and the second driven gear 6 are all in idling conditions, and driven shaft 2 does not receive transmission of power, does not have Power output.
In sum, this little inertia clutch of the present embodiment, gear, can make in speed-change process, occur the speed change of three gears, high speed gear, neutral position and low gear can be respectively, only can realize by the adjustment of free-sliding spline cover 7 when this function, not direct mobile cone pulley, reduces the inertia of movement parts, improves operation ease, particularly at high-power transmission link, with the obvious advantage.
