Tooth profile for a set of pinion and cremaillere

摘要

P the present invention relates to the profiles of the teeth and grooves in a rack and pinion assembly. The gear comprises a plurality of teeth, which are received in the respective grooves of the rack. Each tooth has a pair of side walls situated facing a pair of surfaces of the groove, and the sides and the surfaces of the profiles of surfaces is slightly greater than the radius of curvature of the profile of the flanks. A separating force is generated between the pinion and rack when the rotation of the pinion drives a longitudinal movement of the rack and the circular profiles of surfaces and of the sides cooperate in order to reduce in high proportions, this force, when the rack is slightly moved apart relative to the pinion. p / p applications to the drive systems by pinion and rack. / p
