<p>The invention relates to a gearing assembly comprising a fixed gearing and a gear wheel that rolls off said fixed gearing using two toothed bars, whereby the gear wheel is transferred from one toothed bar to the other toothed bar during the rolling displacement. The aim of the invention is to provide a gearing assembly of this type, in which the axis of a gear wheel that rolls off the toothed bars can pass through a trajectory comprising a bend point. A recess is formed between the two toothed bars (26, 28), which prevents the gear wheel (10) from meshing with both toothed bars (26, 28) at the same time. A transition gearing is formed by a toothed arc (42) that is convex or linear in relation to the rolling gear wheel (10). The gear wheel (10), once meshed with the transition gearing (30), releases its engagement with one toothed bar (26) before meshing with the other toothed bar (28).</p> |
