Abstract
A threaded drive has a threaded spindle having a longitudinal axis, a supporting nut which is in a screw engagement with the threaded spindle with a first clearance and which is rotatable relative to the threaded spindle about the longitudinal axis, a catch nut which is in a screw engagement with the threaded spindle with a second predetermined clearance which is greater than the first predetermined clearance, the catch nut being freely rotatable relative to the supporting nut, and also being bringable in a clamping engagement with the supporting nut and fixable on the supporting nut in any desired relative rotary position.
Claims17
A threaded drive comprising a threaded spindle having a longitudinal axis;
- a catch nut which is in a screw engagement with said threaded spindle with a first clearance and which is rotatable relative to said threaded spindle about said longitudinal axis;
- a catch nut which is in a screw engagement with said threaded spindle with a second predetermined clearance which is greater than the first predetermined clearance, said catch nut being freely rotatable relative to said supporting nut without an interlocking positive connection but with a non-positive frictional cooperation in a peripheral direction, and also being clampingly engageable with said supporting nut and fixable on said supporting nut in a desired relative rotary position.
