But, in prior art, the above-mentioned syndeton needs that concentric, differential multi-load connect of can not satisfying the demand, and structural load, manufacturing cost is high.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of simple in structure, manufacturing cost is low, can meet concentric multi-load connect a kind of concentric twin shaft double-speed motor.
In order to solve the problems of the technologies described above, the technical solution of the utility model is that a kind of output of concentric twin shaft double-speed motor output shaft is worm screw, also comprise worm gear, worm-wheel shaft, central shaft reduction gearing, concentric outer shaft reduction gearing, central shaft axle sleeve, central shaft driven gear, the outer shaft transmission gear of concentric, concentric outer shaft axle sleeve, housing, the worm and wheel engagement of motor output shaft output; The two ends of worm-wheel shaft are connected with housing respectively, and worm gear, central shaft reduction gearing, concentric outer shaft reduction gearing are connected with worm-wheel shaft respectively; Central shaft axle sleeve one end is connected with housing, the other end is connected with concentric outer shaft axle sleeve, the other end of concentric outer shaft axle sleeve is connected with housing; Central shaft driven gear is connected with central shaft axle sleeve and engages with central shaft reduction gearing, and the outer shaft transmission gear of concentric is connected with concentric outer shaft axle sleeve and engages with concentric outer shaft reduction gearing.
Further, the gearratio of central shaft driven gear and central shaft reduction gearing is less than the gearratio of the outer shaft transmission gear of concentric and concentric outer shaft reduction gearing.
Further, to be connected with housing be to be connected with housing by bearing for worm-wheel shaft, central shaft axle sleeve, concentric outer shaft axle sleeve.
Further, to be connected with housing be to be connected with housing by duplex bearing to concentric outer shaft axle sleeve.
Further, the output of motor output shaft is replaceable is motor gear, and worm gear is travelling gear more, the axially parallel of the axial and former worm-wheel shaft of motor shaft, and motor gear and travelling gear are connected with a joggle.
Adopt technique scheme, owing to having used the motor output shaft of worm screw, also comprise worm gear, worm-wheel shaft, central shaft reduction gearing, concentric outer shaft reduction gearing, central shaft axle sleeve, central shaft driven gear, the outer shaft transmission gear of concentric, concentric outer shaft axle sleeve, the technical characterictics such as housing, the two ends that make the utility model efficiently solve motor shaft in prior art connect load, or connect the technical problem that can not solve concentric multi-load connection by the output connection gearbox of motor shaft in same direction or different directions multi-load, the utility model can effectively meet the requirement that concentric multi-load connects, and manufacturing cost is low, simple in structure.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further. It should be noted that at this, be used for helping to understand the utility model for the explanation of these embodiments, but do not form restriction of the present utility model. In addition,, in each embodiment of described the utility model, related technical characterictic just can combine mutually as long as do not form each other conflict.
As shown in Figures 1 and 2, a kind of output of motor output shaft of concentric twin shaft double-speed motor is worm screw 1, also comprise worm gear 2, worm-wheel shaft 3, central shaft reduction gearing 4, concentric outer shaft reduction gearing 5, central shaft axle sleeve 6, central shaft driven gear 7, the outer shaft transmission gear 8 of concentric, concentric outer shaft axle sleeve 9, housing 10, the worm screw 1 of motor output shaft output engages with worm gear 2; The two ends of worm-wheel shaft 3 are connected with housing 10 respectively, and worm gear 2, central shaft reduction gearing 4, concentric outer shaft reduction gearing 5 are connected with worm-wheel shaft 3 respectively; Central shaft axle sleeve 6 one end are connected with housing 10, the other end is connected with concentric outer shaft axle sleeve 9, the other end of concentric outer shaft axle sleeve 9 is connected with housing 10; Central shaft driven gear 7 is connected with central shaft axle sleeve 9 and engages with central shaft reduction gearing 4, and the outer shaft transmission gear 8 of concentric is connected with concentric outer shaft axle sleeve 9 and engages with concentric outer shaft reduction gearing 5. Technique scheme manufacturing cost is low, simple in structure, effectively ensured motor output shaft realized concentric multi-load connect. More specifically, the gearratio of central shaft driven gear 7 and central shaft reduction gearing 4 is less than the gearratio of the outer shaft transmission gear 8 of concentric and concentric outer shaft reduction gearing 5, and this technical scheme has realized the velocity of rotation of central shaft and the differential of concentric outer shaft velocity of rotation rotates. It is to be connected with housing 10 by bearing that worm-wheel shaft 3, central shaft axle sleeve 6, concentric outer shaft axle sleeve 9 are connected with housing; It is to be connected with housing 10 by duplex bearing that concentric outer shaft axle sleeve 9 is connected with housing 10, effectively ensure the reliability and stability that worm-wheel shaft 3, central shaft axle sleeve 6, concentric outer shaft axle sleeve 9 connect, rotate, effectively improved the performance of concentric twin shaft double-speed motor. In specific implementation process, the output of motor output shaft can also be replaced by motor gear, more travelling gear of worm gear 2, the axially parallel of the axial and worm-wheel shaft 3 of motor shaft, motor gear and travelling gear are connected with a joggle.
Below by reference to the accompanying drawings embodiment of the present utility model is explained in detail, but the utility model is not limited to described embodiment.
