Abstract (en)
The gear has a drive gear (1) comprising a drive sector having identical epicyclical teeth (100) and a non-toothed positioning gear (101). The drive gear and a driven gear (2) gear with each other by their respective teeth when the gears are placed in respective predefined positions. The gear (2) comprises truncated teeth (201, 202) having free surfaces (210, 220) with shape complimentary to that of the gear (101) when the surfaces are disposed with respect to the gear (101). The teeth are arranged and numbered such that the tapered teeth of the gear (2) face the gear (2). An independent claim is also included for a driven gear for gearing a timepiece.
