ABSTRACT:
The invention concerns a gear for precision devices comprising at least two mutually co-operating toothed wheels (10, 14). The teeth (12, 16) of the two wheels have the same thickness (e) and the teeth of one of them (10) are provided with a radial slot (26) which divides them into half-teeth (22, 24). On of said half-tooth (24) comprises a recess (28) enabling its elastic deformation in case of overloading.
