Abstract

878,638. Measuring rotor unbalance electrically. AVERY Ltd., W. & T. Feb. 25, 1958 [Aug. 29, 1957], No. 5985/58. Addition to 878,637. Class 40 (1). The expression for the unbalance masses of a rotor in preselected planes in terms of the unbalance forces at the bearings involves the distances between the balancing and bearing_ planes, and the invention relates to a potentiometric device for determining . the required quotients of the distances. The distances between the bearing planes L, R (Fig. 1), and the balancing planes 1, 2 are measured on a scale 115b, and repeated by the contacts 202 &c. (Fig. 2), of slide-wire potentiometer 111 adjusted by calibrated control knobs XL &c. The voltages between selected contacts are indicated by voltmeters JL<SP>1</SP> &c. The currents through the slide wire are adjusted by rheostats PM1, PM2 to make the voltage of the divisor equal to unity, when the voltmeters indicate the values of the quotients. The apparatus is shown duplicated to allow two sets of quotients to be determined simultaneously. Specifications 735,657 and 751,688 also are referred to.
