Abstract
In a preferred embodiment, an apparatus, including: a first nut half (40) and a second nut half (42) each having internal threads (50, 52) complementary with threads on a screw inserted therein; the first nut half (40) and the second nut half (42) having first and second tapers (60, 62), respectively, defined therearound in adjacent surfaces thereof on proximal portions of the first nut half (40) and the second nut half (42); an annular retaining ring (80, 200, 220) having complementary third (92) and fourth (94) tapers defined therearound, with the first taper (60) engaging the third taper (92) and the second taper (62) engaging the fourth taper (94); and biasing apparatus (110, 180, 266) forcing the annular retaining ring (80, 200, 220) inwardly, thus eliminating backlash.
Claims10
An apparatus, comprising:
- (a) a first nut half and a second nut half each having internal threads complementary with threads on a screw inserted therein;
- (b) said first nut half and said second nut half having first and second tapers, respectively, defined therearound in facing alignment on adjacent proximal portions of said first nut half and said second nut half;
- (c) an annular retaining ring comprising complementary third and fourth tapers defined therearound, with said first taper engaging said third taper and said second taper engaging said fourth taper;
- wherein said annular retaining ring further comprises a fifth taper defined in an outer peripheral circumference thereof, said fifth taper extending across a width of the outer peripheral circumference of the annular retaining ring;
- and
- (d) biasing means capable of forcing said annular retaining ring inwardly, thus eliminating backlash,
- wherein said annular retaining ring is forced inwardly between the adjacent proximal portions of the first nut half and second nut half, whereby the annular retaining ring is intermediate the first nut half and the second nut half.
An apparatus, comprising:
- (a) a first nut half and a second nut half each having internal threads complementary with threads on a screw inserted therein;
- (b) said first nut half and said second nut half having first and second tapers, respectively, defined therearound in facing alignment on adjacent proximal portions of said first nut half and said second nut half;
- (c) an annular retaining ring having complementary third and fourth tapers defined therearound, with said first taper engaging said third taper and said second taper engaging said fourth taper, wherein said annular retaining ring is a split annular ring having a single gap formed therein and three notches arranged around an exterior of said annular ring, said single gap and said three notches being spaced approximately equidistant from each other;
- and
- (d) biasing means capable of forcing said annular retaining ring inwardly, thus eliminating backlash,
- wherein said annular retaining ring is forced inwardly between the adjacent proximal portions of the first nut half and second nut half, whereby the annular retaining ring is intermediate the first nut half and the second nut half.
