Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the sectional view of the speed reducer of a kind of motor of the present utility model;
Wherein: 1, casing, 2, Large Gear Shaft During, 3, pinion shaft, 4, first intermediate solid drive shaft, 5, the first outer transmission shaft, 6, gearwheel, 7, second intermediate solid drive shaft, 8, the second outer transmission shaft, 9, small gear, 10, sprocket wheel, 11, bearing.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of speed reducer of motor, a kind of speed reducer of motor, comprise casing 1, pinion shaft 3, Large Gear Shaft During 2, small gear 9, gearwheel 6, sprocket wheel 10, Large Gear Shaft During 2 flexibly connects by bearing 11 and casing 1, it has the first inner transmission shaft 4, first outer drive shafts 5, the first inner transmission shaft 4 is provided with gearwheel 6, the first inner transmission shaft 4 and gearwheel 6 whole settings, first outer drive shafts 5 is connected with sprocket wheel 10, pinion shaft 3 flexibly connects by bearing 11 and casing 1, it has the second inner transmission shaft 7, second outer drive shafts, 8, the second inner transmission shafts 7 are provided with small gear 9, the second inner transmission shafts 7 and small gear 9 whole settings, small gear 9 is meshing with gearwheel 6, and second outer drive shafts 8 is connected with motor.
The utility model gearwheel 6 was selected for use 1: 5 with the gear ratio of small gear 9, and modulus can be chosen the high displacement straight toothed spur gear of 1mm or 1.25mm, and modification coefficient is generally between 0.28-0.40.During work, when small gear 9 was rotated counterclockwise with the revolution of 7500r/min, gearwheel 6 can turn clockwise with the revolution of 1500r/min, if rotating speed is too high, can also slow down once more by the reduction speed ratio of sprocket wheel 10.
