Abstract

1361991 Screw-and-nut gearing JAMES NEILL HOLDINGS Ltd 14 June 1972 [11 June 1971] 27386/71 Heading F2Q [Also in Division G1] In a screw-and-nut mechanism, 5, 17, free play and backlash between the screw 5 and nut 17 is eliminated by forming the nut of a compressible material (e.g. a plastics material), positioning the nut in a counterbore of a tubular stem 6 and compressing the nut with a flange 19 of a cap ring 20 which is screwed to the outside of the tubular stem 7. The nut, which has a plain bore portion 18, is compressed between the shoulder at the end of counterbore and the flange 19 and can be longer than the counterbore, as shown, or shorter with the flange 19 having an annular lip turned in. The frictional engagement between the compressed nut 17 and the tubular stem 6 prevents it from rotating. The invention is shown incorporated in a micrometer, and may also be applied to a depth gauge.
