Abstract

L'invention concerne un dispositif pour compenser l'erreur de course due à l'usure de la meule dans une machine à rectifier les cames. Dans ce dispositif, qui comporte au moins une came de contrôle 15 bloquée sur une broche porte-pièce et six galets de guidage 22 contre l'un desquels est appliquée la came de controle, des paliers séparés pour les galets de guidage sont montés sur un support commun 21 en étant décalés les uns par rapport aux autres perpendiculairement à la broche porte-pièce, et les galets de guidage 22 portés dans ces paliers sont situés dans un plan commun perpendiculaire à ladite broche et dans lequel le support 21 peut être déplacé. Application notamment aux machines à rectifier les cames d'arbres à cames.The invention relates to a device for compensating for the stroke error due to the wear of the grinding wheel in a cam grinding machine. In this device, which comprises at least one control cam 15 locked on a workpiece carrier spindle and six guide rollers 22 against one of which the control cam is applied, separate bearings for the guide rollers are mounted on a common support 21 being offset with respect to each other perpendicular to the workpiece carrier spindle, and the guide rollers 22 carried in these bearings are located in a common plane perpendicular to said spindle and in which the support 21 can be moved. Application in particular to machines for grinding the cams of camshafts.
