Linear movement for machine tool

Abstract

Abstract 1. Device for generating reciprocating linear movements in machines such as manufacturing equipment, especially machine tools, having a rigid bed, having two rigid parallel bearing blocks arranged with spacing and extending in the same direction away from the bed, having a threaded spindle, the two ends of which are held each in a bearing block spaced from the bed, having an electric drive motor rotating to right and left, which comprises a stator and a rotor, having a measuring device recognising the angular position of the rotor, having a spindle nut seated on the threaded spindle and movable in the range between the bearing blocks, having an entraining device which is entrained by the spindle nut in axially play-free manner, having a work carriage on which the entraining device acts and having a guide device which guides the work carriage, characterised by the following features : a) the threaded spindle (16) is clamped in under tension stress non-rotatably between the bearing blocks (12, 13), b) the spindle nut (24) is mounted rotatably on the entraining device (28, 29), c) the rotor (32) is connected unrotatably with the spindle nut (24) and arranged coaxially with the longitudinal axis (37) of the threaded spindle (16), d) the stator (33) is rigidly connected with the work carriage (31).
