<p>A no-backlash gearing mechanism comprises meshing toothed elements (26, 28). At least one of the toothed element has a number of teeth having an undulated, 'S'-shaped, transverse section. The teeth are arranged such that, when the toothed elements mesh, one of the teeth having the undulated form makes at least one point of contact (A, B) with each of two opposing adjacent teeth of the other element thus preventing backlash.</p> |
