Abstract
1,238,457. Determining unbalance. ROTAX Ltd. Nov.20, 1968 [Dec.5, 1967], No.55188/67. Heading G1X. Apparatus for determining the static unbalance of a rotatable device 18 comprises a vertically disposed tubular column 16 universally supported on a fixed arm 11 by means of knife edges 12, 14 disposed on axes at right angles to each other and cradles bearing on the knife edges 13, 15, the cradle 15 being secured to the column 16, a light source 20 within the column directing beams of light limited by apertured plates 21 along opposite directions on the axis of the column 16, and scales 24, 25 on which the respective light beams impinge and which by the position of the points at which the light strikes the respective scale will give an indication of any static unbalance of the device 18. The column 16 carries a bearing plate 17 for the device 18 and a counterweight 19 the position of which is adjustable longitudinally of the column to vary the sensitivity of the apparatus. The plates 21 may be replaced by lenses and the scale 25 which is used when the device 18 does not have a central aperture may be replaced by mirrors reflecting the light to a scale fixed at another point of the apparatus. A clamp mechanism 26 may be provided to prevent movement of the column 16 until required and this may include a clamping device. To improve the accuracy of the apparatus the knife edges 12, 14 may be disposed in one plane.
