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.
Claims16
Gear for precision devices comprising at least two toothed wheels (10, 14) cooperating with each other and without any clearance, wherein:
- the teeth (12) of one of the wheels (10) are provided with a radial slot (26) which divides them into two half-teeth (22, 24), and
- one of said half-teeth (24) comprises a recess (28) enabling it to be deformed elastically upon compression,
- characterized in that the other half-tooth (22) is complete and has sufficient rigidity to properly ensure transmission of the forces to which it is subjected.
