ABSTRACT:
The invention relates to a backlash-compensating toothed moving part, for a precision gear assembly, particularly in clock-making, in which the backlash-compensating teeth each have a section extending symmetrically to both sides of the radius of said mobile passing the tip of said teeth with an elastic connection to said mobile to give said teeth a freedom of movement in the plane of the mobile, at least one tooth in two being a backlash-compensating tooth comprising stop means arranged to limit the freedom of movement as a function of the backlash in the gear assembly to be compensated for.
