Fig. 1 is the solid combination scheme drawing of the utility model reductor.
Fig. 2 is the perspective exploded view of the utility model reductor.
Fig. 3 is the generalized section of the utility model reductor.
Fig. 4 is that the utility model reductor is implemented view.
Fig. 5 is another enforcement view of the utility model reductor.
Fig. 6 is the generalized section of existing reductor.
Seeing also shown in Figure 1ly, is three-dimensional combination scheme drawing of the present utility model.Hand-held design battery-driven car reductor of the present utility model is to be established for 30 groups by an electro-motor 10, a train of reduction gears 20, reducer shell to form (please cooperate and consult shown in Fig. 2,3).
Electro-motor 10 has an axle drive shaft, which is provided with gear and form a driven wheel 11 for takeoff outputs, and integral body can be made for its power supply by storage battery.
Train of reduction gears 20 has first gear cluster 21 and second gear cluster 22.This first gear cluster 21 is provided with a transmission shaft 211, one group of big spur pinion.These big sheathed transmission shaft 211 left sides that are fixed at of spur gear T1 are meshed with the driven wheel 11 of above-mentioned electro-motor 10 again.And than in the spur pinion T2 axle, the left side then is equipped with a bearing 212, and the right side is equipped with a free-wheel clutch 213, and is sheathed with transmission shaft 211 right sides again in it, and buckles 215 with a pad 214 and a C type in regular turn and support solid buckle in the outside.Second gear cluster 22 then has an output shaft 221, an outer shaft 222 and spur gear T3.This outer shaft 222 has stepped axis hole, and its axis hole right side is equipped with a bearing 223, and the left side is equipped with a free-wheel clutch 224, and with a C type buckle 225 support in outside buckle solid.Outer shaft 222 is inner, and cover is sincere mutually with output shaft 221, makes outside output shaft 222 two ends convexedly stretch in, and its outside appropriate location is solid with the mutual sheathed spiral shell of this spur gear T3 again.
Seeing also shown in Figure 3ly, is the generalized section of the utility model reductor.Reductor of the present utility model is direct driven wheel 11 outputting powers by electro-motor 10, and the spur gear T1 that conducts to again on the transmission shaft 211 produces the F/s deceleration.The multiple deceleration that produces subordinate phase by the spur gear T3 engagement of spur gear T2 on the transmission shaft 211 and output shaft 221.Drive output shaft 221 outside outputting powers by spur gear T3 again.Now because the power take-off shaft of this electro-motor 10 is directly to be made as driven wheel 11, cooperate spur gear T1 and the coaxial setting of spur gear T2 again, spur gear T3 sets up an outer shaft 222 and output shaft 221 coaxial settings, makes reductor of the present utility model only need three transmission spur gears can obtain splendid reduction ratio effect.More because the number of gears and the transmission number of axle reduce, make overall volume more exquisite, it is more convenient to assemble.And this output shaft is established socket with an outer shaft and its axle, except that the body footpath that can dwindle output shaft, more can therefore lower weight, makes whole lightweight.
In addition, the inner appropriate location of the axis hole of this spur gear T2 and outer shaft 222 respectively is equipped with a free-wheel clutch 213,224.Wherein, utilize the setting of the free-wheel clutch 213 in this spur gear T2 axis hole, when the moving motor 10 of can powering turns round, make output shaft 221 can make reverse lost motion.And the free-wheel clutch 224 in these outer shaft 222 axis holes is provided with, and is can power moving motor 10 when static, prevents that output shaft 221 is driven when just changeing by external force, the driving that electro-motor 10 is produced, and form idling conditions.So reductor of the present utility model can use on various car bodies, is installed in the hind axle or the five-way axle place of bicycle shown in Fig. 4,5, or the rear wheel of Kickboard Scooter, forms a Vidacare corp.
In sum, the utility model hand-held design battery-driven car reductor, not only effectively reduced volume, expendable weight and robust structure have more splendid reduction ratio, improve the effect of transmission efficiency.
