Abstract

Linearführung (50) für Werkzeugmaschinen (10), umfassend eine sich in einer Längsrichtung (52) erstreckende und in der Längsrichtung (52) eine konstante Querschnittsform (56) aufweisende Führungsschiene (54) sowie mindestens einen an der Führungsschiene (54) geführten und die Führungsschiene (54) in Teilbereichen der Querschnittsform (56) umgreifenden Führungswagen (110), dadurch gekennzeichnet, dass der Führungswagen (110) an der Führungsschiene (54) durch mindestens eine Gleitführung (120) geführt ist, welche mindestens eine an der Führungsschiene (54) vorgesehene Gleitstützfläche (124) aufweist, an welcher eine Gleitauflagefläche (126) des Führungswagens (110) anliegt, dass der Führungswagen (110) an der Führungsschiene (54) durch mindestens eine Wälzkörperführung (130) geführt ist, welche mindestens eine an der Führungsschiene (54) angeordnete Wälzkörperlaufbahn (132) und eine am Führungswagen (110) vorgesehene Wälzkörperanordnung (119) aufweist, deren Wälzkörper (116) sich abwälzend längs der Wälzkörperlaufbahn (132) der Führungsschiene (54) bewegbar sind, und dass die mindestens eine Gleitführung (120) und die mindestens eine Wälzkörperführung (130) so angeordnet und ausgebildet sind, dass sie auf den Führungswagen (110) und senkrecht zur Längsrichtung (52) der Führungsschiene (54) wirkende jedoch unterschiedlich ausgerichtete Stützkräfte (GS, WS) aufnehmen.
