Summary of the invention
Be subjected to force direction inconsistent at existing transmission mechanism and the main shaft that rotates counterclockwise vacuum circuit-breaker, loss combined floodgate energy expends the combined floodgate merit, reduces the transmission stability of vacuum circuit-breaker, shadow
Ring the vacuum circuit-breaker connecting-disconnecting function, take defectives such as the transmission space is big, the invention provides a kind of transmission mechanism of the vacuum circuit-breaker that clockwise rotates, when working, the transmission mechanism of this vacuum circuit-breaker that clockwise rotates is subjected to force direction consistent with main shaft, off-energy does not exert an influence to the vacuum circuit-breaker feed motion, improves transmission stability and the transmission efficiency of vacuum circuit-breaker, promote the vacuum circuit-breaker connecting-disconnecting function, and it is little to take the transmission space.
Taked following technical scheme for realizing purpose of the present invention:
A kind of transmission mechanism of the vacuum circuit-breaker that clockwise rotates, the transmission mechanism of this vacuum circuit-breaker that clockwise rotates comprises framework, with bolt decelerator is arranged at the framework internal upper part, output shaft at decelerator fixedly has cam, decelerator outer wall below cam fixedly has the connection connecting lever, cam be connected connecting lever and touch mutually; Connecting an end of connecting lever and an end of combined floodgate connecting rod is fixed together; Main shaft is fixedly arranged at the bottom in framework, and coaxial on main shaft fixedly have combined floodgate connecting lever and a contact connecting lever, and the other end of combined floodgate connecting rod and combined floodgate connecting lever are fixed together; It is characterized in that being with spring at a wherein joint push rod of push rod group, the contact connecting lever links to each other with an end that is with spring push-rod, and an end of another joint push rod of push rod group is fixed on outside the framework; Angle between combined floodgate connecting rod and combined floodgate connecting lever junction and the Y-axis is positive angle.
Described positive angle is+20 degree～+ 60 degree, and optimum angle is+53.5 degree
Characteristics of the present invention are simple in structure, easy to manufacture, easy to use; Its remarkable result is transmission mechanism when work of vacuum circuit-breaker to be subjected to force direction consistent with main shaft, and off-energy not improves transmission stability and the transmission efficiency of vacuum circuit-breaker, lifting vacuum circuit-breaker connecting-disconnecting function, and it is little to take the transmission space.
Description of drawings
The structural representation of Fig. 1, existing vacuum circuit-breaker;
The structural representation of Fig. 2, one embodiment of the invention;
Among the figure: 1, framework 2, construction bolt 3, decelerator 4, cam 5, connection connecting lever 6, combined floodgate connecting rod 7, combined floodgate connecting lever 8, main shaft 9, contact connecting lever 10, bearing pin 11, push rod group.
Embodiment
As shown in Figure 2, in the way 1 is framework, with bolt 2 decelerator 3 is arranged fixedly at framework 1 internal upper part, at the output shaft of decelerator 3 cam 4 is arranged fixedly, decelerator 3 outer walls below cam 4 fixedly have the connecting lever 5 of connection, and an end that connects connecting lever 5 links to each other with combined floodgate connecting rod 6; Main shaft 8 is fixedly arranged at the bottom in framework 1, and coaxial on main shaft 8 fixedly have combined floodgate connecting lever 7 and a contact connecting lever 9, and the other end of combined floodgate connecting rod 6 and combined floodgate connecting lever 7 are fixed together; Contact connecting lever 9 links to each other with the push rod that the wherein joint of push rod group 11 be fixed on framework 1 by bearing pin 10 in is with spring, and the end that another of push rod group 11 saves push rod is fixed on outside the framework 1; Angle between combined floodgate connecting rod 6 and combined floodgate connecting lever 7 junctions and the Y-axis is positive angle (+53.5 degree).
