| 摘要 |
A screw-nut screw transmission coupling with ball circulation of the type comprising a first elongated element and a second tubular element substantially coaxial to each other and with an external and an internal helical track respectively, is described. Said two tracks are disposed facing each other to define a helical rolling path for a plurality of balls disposed in mutual contact along said path and along a recirculation duct connecting the two ends of said path together, and said first element is constituted by an inner core and a metal strip wound in a cylindrical helix about and along said core, said strip being rigid with said core and having a cross-section which is concave outwards to define one of said helical tracks. |
