Abstract
A backlash-compensating mobile (1) intended to form a gear with a second mobile (2) and having rigid teeth (4, 5) and backlash-compensating leaf springs (16), is characterized in that the rigid teeth (4, 5) are distributed in groups of consecutive teeth, each group having a first rigid tooth (4) and a second rigid tooth (5) having respective mutually facing meshing flanks (10, 11) to permit the displacement of the second mobile (2) in both directions, and in that the leaf springs (16) are interleaved between these groups in spaces not intended to receive the teeth (3) of the second mobile (2), and extend beyond the tip circle (Ca) of the rigid teeth (4, 5) in order to cooperate with the second mobile (2).
Claims16
A backlash-compensating mobile comprising:
- a first mobile and a second mobile,
- the first mobile having rigid teeth and backlash-compensating leaf springs, wherein:
- the rigid teeth are distributed in groups of consecutive teeth, each group having a first rigid tooth and a second rigid tooth,
- the first rigid tooth and the second rigid tooth each have a respective mutually facing meshing flanks to permit the displacement of the second mobile in both directions, and
- the backlash-compensating leaf springs are interleaved between said groups of consecutive teeth in spaces not intended to receive the teeth of the second mobile, and
- a free end of the backlash-compensating leaf springs extends beyond the tip circle of the rigid teeth in order to cooperate with the second mobile.
