Abstract

1409506 Screw-and-nut gearing LA TECHNIQUE INTEGRALE SA 19 Oct 1973 [20 Oct 1972] 48874/73 Heading F2Q In a ball screw-and-nut mechanism, the screw and nut 2 are formed respectively with helical grooves 5 which define a recirculating ball passage having the same pitch as, and located between, load carrying ball grooves 3. The dimensions of the grooves 5 are slightly greater than those of the grooves 3. End plates 6a, 6b are secured to the nut 2 and ducts 11a1, 11a2, 11b1, 11b2 interconnect the ends of the grooves 3 and recirculating grooves 5. Fingers 12a, 12b are secured to the ends of the nut 2 to facilitate the passage of the balls.
