Abstract
A method for generating a tooth space profile between two teeth of a wheel engaging with a roller pinion in a reference plane perpendicular to a central axis (X1) whose intersection with the reference plane defines a centre (C). The method comprises defining a nominal tooth space with symmetrical first and second profiles so that the space is suitable for receiving a roller which comes into contact, without clearance, with the facing active portions of the first and second profiles at the level of a primitive diameter. The method further comprises the steps of deforming the bottom portion of the first profile so that the bottom point is brought nearer to the centre by an amount equal to a given radial clearance, and moving the first profile angularly through a given angular half-clearance around the centre to shift it away from the radial axis.
