Crank flying shear gear box

The utility model discloses a crank flying shear gear box, include: the plastic width -lock type single -layer sealed packing case comprises a casin. First input shafting, first output shafting, second input shafting, second output shaft system. Wherein first input shafting and first output shafting pass through gear engagement, and second input shafting is through gear engagement with second output shaft, all is equipped with the flywheel on first input shaft and the second input shaft. According to law of conservation of energy, first flywheel, second flywheel inertia is transformed into onfirst output shaft and the second output shaft with square relation of velocity ratio to during the same inertia of demand, the great weight that has reduced the flywheel has makeed the lightweight ofwhole device. And the setting of flywheel can reduce motor rotation number's fluctuation, the motor operation is more steady. 本实用新型公开了种曲柄飞剪齿轮箱，包括：箱体；第输入轴系；第输出轴系；第二输入轴系；第二输出轴系。其中第输入轴系与第输出轴系通过齿轮啮合，第二输入轴系与第二输出轴系通过齿轮啮合，第输入轴与第二输入轴
