<p>1. A device for reducing the radial operational play between meshing teeth and/or gears, particularly between a fixed external ring gear (9) having internal toothing (12) and at least one pinion (8) meshing with this internal toothing (12), characterised in that the fixed ring gear (9) with internal toothing (12) has, externally, a conical shape (13, 14) and in that there is provided at least one female part (15, 16) of annular shape having a conical bore (17, 18) complementary to the conical shape (13, 14) of the fixed ring gear (9) constituting a male part, the female part or parts (15, 16) having a radial rigidity greater than that of the male part (9), and means (20) being provided to apply an axial force to at least one female part (15, 16) and drive it onto the male part (9) so as to compress the latter radially along the whole of its periphery, and thus reduce the radial play between its internal toothing (12) and that of the pinion or pinions (8).</p> |
