Abstract:
1. A backlash-compensating moving part for a precision gear assembly, particularly of a timepiece, said moving part comprising a central plate and a plurality of teeth, wherein said teeth include a plurality of backlash-compensating teeth, wherein each backlash-compensating tooth comprises: wherein a respective first through slot is formed between the rigid portion and each of the elastically deformable portions, said respective first through slot having a respective width corresponding substantially to a respective backlash to be compensated for, and wherein free tips of said elastically deformable portions extend radially beyond a tip of the rigid portion and are separated from each other by a second through slot whose width is such that that the rigid portion serves as the only stop for each of the elastically deformable portions, so as to limit an amplitude of movement of each of the elastically deformable portions as a function of the respective backlash to be compensated for.
