The utility model is to be achieved through the following technical solutions：
A kind of circuit breaker transmission device, including support, the bar inputted for power, for the connecting lever of power output, and
The set transmitted for power；Described support is horizontally arranged with notch, is vertically arranged with the through hole through notch；Described set two
End is slidably matched in through-holes, and outer middle side part is fixedly connected the connecting lever being arranged in notch；Described bar is fixedly connected in set
Portion.
It is preferred that, cover outer middle side part and set in raised outer six side, interior six side coordinated with outer six side is provided with connecting lever
Hole.
Further, the annular boss that the side of connecting lever is set by outer six sides one end is positioned, what opposite side was put by being set in
Pad is positioned.
It is preferred that, one end of set is slidably connected with being nested in notch side axle sleeve, and the other end is with being arranged on notch opposite side
Bearing be fixedly connected.
It is preferred that, the side of bearing contacts positioning with the annular boss that outer six sides one end is set, and opposite side is logical with being arranged on
Back-up ring contact positioning in hole.
It is preferred that, set is internally provided with internal spline, coordinates with the external splines that bar one end is set.
Further, bar is set in multi-diameter shaft, sets one end diameter of external splines to be less than the other end, the shaft shoulder contacts fixed with set
Position.
It is preferred that, described through hole is set in shoulder hole, is covered and is coordinated from one end insertion of shoulder hole with it.
Compared with prior art, the utility model has following beneficial technique effect：
Each part in transmission device is carried out modularization setting by the utility model, completes to connect power input using set
Enter the output with power, the adaptation to multiple drive disk assemblies can be completed using different sets, while driving end need not be changed
Coordinate；It is spacing using the connection of setting, it ensure that the reliability and stably of transmission；The setting of supporting structure is without other appendicles
Part, the arrangement to connecting lever is realized by groove, realizes the positioning to connecting lever by hole, it is desirable to which low, adaptability is good, can set
In the various positions for needing to be driven of breaker, the space occupied is small, and easy to use and flexible is reasonable in design, easy to assembly, and performance can
Lean on.
Further, pass through the Horizontal limiting to connecting lever, it is ensured that position during transmission is accurate, is oriented to smoothness, coordinate steady
It is fixed.
Further, by the positioning and limitation to set, the connecting lever accurate positioning for connecting it, convenient and reliable assembly.
