Embodiment Construction
[0024] figure 1 It is the structural principle diagram of the first embodiment of the present invention, as shown in the figure: the electronically controlled anti-backlash variable tooth thickness gear pair in this embodiment includes the variable tooth thickness gear I1 and the variable tooth thickness gear meshed with the variable tooth thickness gear I1 gear II2 and an electronically controlled anti-backlash system, the electronically controlled anti-backlash system at least includes an electronically controlled power device 4 that applies an axial mechanical force for adjusting the backlash to the variable-tooth-thickness gear I1 or / and the variable-tooth-thickness gear II2, and the backlash-adjusting The direction of the axial mechanical force is the direction of eliminating the backlash between the variable tooth thickness gear I1 and the variable tooth thickness gear II2, that is, the direction of the axial mechanical force of the gap adjustment is the direction in whic...
