Summary of the invention
Inconsistent with main shaft Impact direction for the existing transmission mechanism rotating counterclockwise vacuum circuit-breaker, loss combined floodgate energy, expends combined floodgate merit, the transmission stability of reduction vacuum circuit-breaker, shadow
Ring vacuum circuit-breaker connecting-disconnecting function, take the defects such as transmission space is large, the invention provides a kind of transmission mechanism of the vacuum circuit-breaker rotated clockwise, it is consistent with main shaft Impact direction when the transmission mechanism of this vacuum circuit-breaker rotated clockwise works, not off-energy, does not have an impact to vacuum circuit-breaker feed motion, improves transmission stability and the transmission efficiency of vacuum circuit-breaker, promote vacuum circuit-breaker connecting-disconnecting function, and it is little to take transmission space.
Following technical scheme is taken for realizing object of the present invention:
A kind of transmission mechanism of the vacuum circuit-breaker rotated clockwise, the transmission mechanism of this vacuum circuit-breaker rotated clockwise comprises framework, decelerator is fixed with at framework internal upper part bolt, the output shaft of decelerator is fixed with cam, decelerator outer wall below cam is fixed with connection connecting lever, cam be connected connecting lever and touch; Connection one end of connecting lever and one end of combined floodgate connecting rod are fixed together; Bottom in framework is fixed with main shaft, and main shaft is coaxially fixed with combined floodgate connecting lever and contact connecting lever, and the other end and the combined floodgate connecting lever of combined floodgate connecting rod are fixed together; It is characterized in that cover has spring on a wherein joint push rod of push rod group, contact connecting lever has one end of spring push-rod to be connected with cover, and one end of another joint push rod of push rod group is fixed on outside framework; Combined floodgate connecting rod and the angle between combined floodgate connecting lever junction and Y-axis are positive angle.
Described positive angle is+20 degree ~+60 degree.
Feature of the present invention is that structure is simple, easy to manufacture, easy to use; Consistent with main shaft Impact direction when its remarkable result is the transmission mechanism work of vacuum circuit-breaker, not off-energy, improves transmission stability and the transmission efficiency of vacuum circuit-breaker, promote vacuum circuit-breaker connecting-disconnecting function, and it is little to take transmission space.
