Abstract

TORNILLO DE BOLAS EN EL QUE ESTAS (13) COOPERAN CON EL TORNILLO (1), AVANZANDO POR UN ROSCADO HELICOIDAL (2) Y EN RANURAS PARALELAS DE UN ANILLO DE RODADURA (4,14,15,23,109,109'') DISPUESTAS COAXIALMENTE EN TORNO AL TORNILLO (1). DICHAS RANURAS (12,12'',112) SE EXTIENDEN PERPENDICULARMENTE AL EJE (11) DEL TORNILLO. EL ANILLO VA MONTADO DE FORMA GIRATORIA LIBRE, PERO AXIALMENTE INMOVIL, EN UNA TUERCA (3,104,105) COLOCADA COAXIALMENTE ALREDEDOR DEL ANILLO DE RODADURA. UNA JAULA DE BOLAS (21) ESTA SITUADA ENTRE EL TORNILLO Y EL ANILLO DE RODADURA, Y VA UNIDA A LA TUERCA (3).
