Background technique
Conventional gear transmission structure is constant-speed ratio transmission, the main gear being meshed by several is realized the transmission of single-stage or multistage speed, in same drive mechanism as will change its output speed, must change to realize by input speed, at input speed one regularly, output speed cannot change, and has greatly limited the application area of constant-seed motor.
Model utility content
Model utility object: the purpose of this utility model is in order to solve the deficiency of above-mentioned technology, provides a kind of constant speed to input the gear transmission structure of two kinds of different rotating speeds of exportable rotating Vortex.
Technological scheme:
A kind of gear transmission structure, comprise input shaft, be fixed on the input gear on input shaft, output shaft, be fixed on the output gear on output shaft, the both sides of described input gear are engaged with respectively the first duplicate gear and the 3rd duplicate gear, described the first duplicate gear and output gear are meshed respectively in the second duplicate gear both sides, described output gear is meshed with described the 3rd duplicate gear, on the first duplicate gear, be provided with overrunning clutch, on the 3rd duplicate gear, be provided with overrunning clutch, be arranged on the single-direction transmission opposite direction of two overrunning clutchs on the first duplicate gear and the 3rd duplicate gear.
Another kind of technological scheme is: a kind of gear transmission structure, comprise input shaft, be fixed on the input gear on input shaft, output shaft, be fixed on the output gear on output shaft, the both sides of described input gear are engaged with respectively the first duplicate gear and the 3rd duplicate gear, described the first duplicate gear and output gear are meshed respectively in the second duplicate gear both sides, described output gear is meshed with described the 3rd duplicate gear, on the second duplicate gear, be provided with overrunning clutch, on the 3rd duplicate gear, be provided with overrunning clutch, the single-direction transmission direction that is arranged on the second duplicate gear and two overrunning clutchs on the 3rd duplicate gear is identical.
Beneficial effect: by overrunning clutch is set on duplicate gear, realize the clutch between duplicate gear two gears, when the sense of rotation of the first gear is contrary with the transmission direction of overrunning clutch, two are out of gear and with other gear, rotate separately, so, change the input direction of the rotating speed of gear, make it along different path transmissions, can realize single input speed and become two kinds of output speeds, can make the motor of fixed rotating speed become two kinds of output speeds from original single output speed, compared with prior art, expanded the using scope of synchronous machine, and be not only confined to a kind of use of rotating speed.
