Abstract

1,178,752. Screw-and-nut gearing. GEORGE RICHARDS & CO. Ltd. 1 May, 1968 [1 May, 1967], No. 19986/67. Heading F2Q. [Also in Division B3] A lead screw and nut traverse for a machine tool slide comprises a lead screw E clamped at various positions A, B, C along its length to prevent flexing thereof, the clamps being opened and closed automatically to allow the drive nut F to pass so that only one clamp at a time is undamped. The clamps are opened and closed hydraulically by providing cams, limit switches or an electrical pick-off. To prevent "hunting" on to and fro movement of the slide the clamping initiating position is spaced nearer to the actual clamp than the unclamping initiating position. The lead screw may be fixed rotationally with the nut F rotatable, or may be rotated relative to a fixed nut. The lead screw may comprise a number of parts screwed together.
