    Patent number: 4369011
    Abstract: Ball nuts are preloaded onto a ball screw by rotating the nuts relative to one another to jam adjacent end faces of the nuts together. Thereafter, the nuts are held against relative rotation by tightening a clamping ring secured to one of the nuts and adapted to frictionally engage the other nut to prevent rotation thereof.

  • Ice breaking and mud deflecting device for a ball screw and nut assembly
    Patent number: 4286793
    Abstract: A ring is telescoped into the end of a nut of a ball screw and nut assembly and carries a lip which breaks ice away from the screw. The plastic insert of relatively short circumferential length is supported by the ring and is urged into the groove of the screw by a spring so as to wipe mud from the screw. A felt strip coacts with the insert to seal the nut against the entry of foreign particles and to restrict the escape of lubricant from the nut.
