Abstract

1348808 Screw-and-nut gearing R GARTNER 28 May 1971 [30 May 1970] 18212/71 Heading F2Q A screw drive comprises a screw 1 encircled by (as shown) three ball or roller bearings 3-5 the outer races 6 of which are held by clamping jaws 7 on three surrounding adjustably threaded spindles 8 of a movable frame 11-14, the bearings 3-5 being held inclined, via the adjustable jaws 7, at the helical pitch angle of the screw 1 and carrying, i.e. secured on their inner races 9, roller rings 3a-5a the centres of which are eccentrically located relative the screw 1 whereby each ring 3a-5a has only a sickleshaped abutment on one of the thread turns of the screw 1, as illustrated at zone 4b (Fig. 2), whereby friction losses &c. are reduced. In Figs. 4 to 7 a single inclined eccentrically located roller ring (16) has a sickle shaped abutment (20) on the screw 1 and is supported on rollers (22, 23) of a movable frame (24, M), the rollers (22, 23) being proportioned in accordance with the offset load point (21) in the sickle zone (20). Various alternative forms of roller rings are illustrated in Figs. 8 to 13 (not shown), the latter of which illustrates a lubricant feed thereto. Figs. 15 and 16 (not shown) illustrate arrangements in which two roller rings are braced towards or away from one another to eliminate backlash.
