Nut mechanism
Abstract
Abstract THE NUT COMPONENT OF A BALL NUT MECHANISM IS COMPOSED OF TWO PARTS FITTED TOGETHER BY AN ENCLOSING SLEEVE. EACH NUT PART CONSISTS OF A MAIN BODY PORTION, IN WHICH THE BALL RECIRCULATION PASSAGE IS LOCATED, AND A RADIALLY DIRECTED END FLANGE. THIS FITS INTO A RECESS AT THE END OF THE SLEEVE, AND THE MAIN PORTION OF THE SLEEVE DEFINED BETWEEN THE TWO RECESSES HAS A LARGER INTERNAL DIAMETER THAN THE EXTERNAL DIAMETER OF THE MAIN PORTIONS OF THE NUT PARTS IN SUCH A MANNER THAT THE LATTER HAVE NO RADIAL CONTACT WITH THE SLEEVE AND THUS ARE RELIEVED OF STRESSES AND SHOCK LOADS. MEANS ARE FURTHERMORE PROVIDED TO ADJUST THE CLEARANCE BETWEEN THE BALLS AND THE GROOVES IN THE SLEEVE AND IN THE NUT PARTS, RESPECTIVELY.
