Abstract

1297291 Screw-and-nut gearing SZERSZAMGEPIPARI MUVEK 30 Jan 1970 4680/70 Heading F2Q, A recirculating ball type screw-and-nut assembly comprises, in a housing 5, two nuts 2, 3 axially spaced apart on a common screw 1 and urged towards one another by adjustably loaded Belleville springs 9 to obviate backlash. Return passages for the balls are milled in the ends and sides of the nuts and covered by end discs 8 abutting the nut ends and cover plates 17 seated in recesses in the nut sides. The cover plates 17 may be secured by screws. Keys 7 prevent rotation of the nuts relative to the housing. The springs 9 react against end nuts 11 screwed into the housing 5 and locked in position by screws 10 and outer nuts 13. Sealing rings 12, 14 are fitted.
