Wheel with a flexible toothing

摘要

Timepiece wheel (10) comprising teeth (2) with play compensation each including a catch (3) projecting from a catch foot (31), and an elastic strip (4) projecting from a strip foot (41) opposite said catch (3) from which said strip (4) is separated by a ventral notch (5) and an intrados profile (43) of which, on the side opposite said catch (3), delimits a dorsal notch (6), said strip foot (41) being delimited, towards the pivot axis (D) of said wheel (10), by an inner end (51) of said ventral notch (5) and by an inner end (61) of said dorsal notch (6).;Said inner end (61) is located closer to said axis (D) than said inner end (51) and extends, on the side of said axis (D) underneath said catch foot (31) or underneath the inner extension (52) of said ventral notch (5) towards said pivot axis (D).

主权项

1. A timepiece wheel comprising teeth with play compensation each including a catch projecting from a catch foot, and an elastic strip projecting from a strip foot opposite said catch from which said strip is separated by a ventral notch and an intrados profile of which, on the side opposite said catch, delimits a dorsal notch, said strip foot being delimited, towards the pivot axis of said wheel, by an inner end of said ventral notch and by an inner end of said dorsal notch, wherein said inner end of said dorsal notch is located closer to said axis than said inner end of said ventral notch, and extends, on the side of said axis, underneath said catch foot or underneath the inner curvilinear geometrical extension of said ventral notch towards said pivot axis.
