Moving part 42, fixed cover 41, the rolling assembling of driving member 42 is in the inside of fixed cover 41.Wherein one end of driving member 42 is used for and driving
The motor output shaft plug-in type rotation stop connection of motor 3, the other end are used for and in Crankarm box 2 and stretch out Crankarm box 2
Connecting lever axle 21 is connected, and one end being connected with connecting lever axle 21 of driving member 42 is provided with internal spline structure 43, corresponding connecting lever
External splines structure is provided with axle 21, driving member 42 is connected with connecting lever axle 21 by spline drived.
One end being connected with motor output shaft of driving member 42 is provided with gear shaping structure 44, and the gear shaping structure 44 includes circumference
Four the first gear shapings uniformly at intervals, a tooth set 31 is arranged with corresponding motor output shaft, and tooth set 31 is included between circumference
Every four uniform the second gear shapings, the first gear shaping and the second gear shaping are in fan-shaped and equal in magnitude, structure between adjacent first gear shaping
Into the gap for the insertion of the second gear shaping, therefore after gear shaping structure 44 and tooth cover 31 pairs and inserted, it is combined into a complete cylindrical drum
Structure, due to the effect of contraction of sector to each other so that motor output shaft realizes effective centering with transmission limit device,
Avoid and sweep thorax caused by motor bias.
In use, one end of fixed cover 41 is weldingly fixed on Crankarm box 2, integrally it is convexly equipped with the inner peripheral surface of fixed cover 41
Stop block 46, the stop block 46 have certain length in sector.Limited block 45 is installed with the outer peripheral face of driving member 42,
Limited block 45 is also in sector, and have certain length, when driving member 42 just goes to certain angle, limited block 45 and stop block
46 end face block coordinates, same when driving member 42 is inverted to so as to limit the rotational limitation of driving member 42 in this direction
During certain angle, the other end block of limited block 45 and stop block 46 coordinates, so as to limit driving member 42 in this direction
Rotational limitation.The length of limited block 45 and stop block 46 is corresponding with the divide-shut brake angle of high-voltage switch gear, according to different points
Combined floodgate angle, the corresponding length of limited block 45 and stop block 46 can be set.
