Abstract

L'invention concerne une machine de mesure avec translation par patins pneumatiques et magnétiques. Pour réduire le frottement entre le chariot-portique 5 et le socle 2 de la machine de mesure, on monte à la base des montants 6 du chariot-portique, des patins pneumatiques 24 à coussin d'air susceptibles de s'élever à environ un centième de millimètre au-dessus de rails-supports. L'équilibre du chariot-portique est obtenu grâce à l'application d'une action antagoniste exercée par des patins magnétiques 25 placés à environ un dixième de millimètre d'un rail ferromagnétique. Application notamment aux machines de mesure et aux machines-outils.
