Device for converting a rotational movement into an axial movement

Worm drive with a roller ring nut

Worm gear with a gear ring nut

A rolling bearing for use with a screwthreaded spindle comprising a relatively thick-walled outer race ring and an inner race ring, rolling members rolling between the two rings, rings of rolling members rolling between the two end faces of the outer race ring and end plates disposed at a distance from the latter faces and connected to the spindle, the end plates being adjustably mounted on the spindle whereby their relative preloading can be adjusted, characterized in that the two end plates have in their bores an internal screwthread corresponding to the screwthread of the spindle and therefore themselves serve for securing and axially adjusting the bearing on the spindle .

Rolling bearing for use with screwthreaded spindles

Novel recirculating rolling bearings for the longitudinally moveable mounting of an element with a linear surface comprising a bearing body having two opposite straight race sections limited by lateral flanges connected by two curved end deflecting sections connecting the ends of the straight sections to form a closed raceway and rolling bodies in said closed raceway rotating about an axis, the bearing body having a cylindrical outer contour and is insertable into a corresponding cylindrical bore of a housing which bore is open toward the element to be supported in the area of one straight race section opposite said element, the common axis of the bearing body and the housing bore having a slight inclination relative to the straight race section opposite the element to be supported.

Recirculating rolling bearing

A roller bearing for the longitudinally moveable mounting of an element with a straight race comprising a bearing body having two race sections of which at least one is straight, the two race sections being connected at their ends to each other by a curved race section at each end to form a closed race for cylindrical rolling elements being secured by retaining means against falling out, the race being laterally bounded by separate flange plates secured to the bearing body, the flange plates being thin-walled elements having in at least part of the race area chiplessly formed on rims being formed in such a way that the material in the area of the rims is offset by a partial amount of the thickness of the flange plates parallel to the latter and towards the race.
