The invention relates to a progressive gearing comprising at least one spur gear (1, 2) and one tooth structure (3, 4, 5, 7, 8) inside of which the spur gear (1, 2) meshes. The spur gear (1, 2) has teeth (11) which are arranged along a curve (10), the curve (10) having a radius of curvature (r) that monotonically increases over an angular range of greater and 90° of the curve (10). The curve preferably has a spiral, particularly a logarithmic spiral. This gearing has a compact and simple design, a uniform course, and enables a late end point. |
