CALIBRATION MANUAL FOR THE ELECTRONIC SYSTEM AND PICKUP OF ANDEROMETERS,

Abstract

The Anderometer is a rolling bearing vibration tester. The purpose of the instrument is to indicate the RMS vibration level, expressed in Anderons, of a bearing with the outer ring kept in a fixed anular position and the inner ring rotating at 1800 RPM. One Anderon, by definition, corresponds to 60 pi microinches/sec. RMS, at a rotational speed of 1800 RPM. The vibration is measured in three frequency bands, nominally 50-300 c (low band), 300-1800 c (medium band) and 1800-10000 c (high band). The Anderometer is designed to measure bearings under light axial load, but no radial load. The Anderometer con tains the following main units: (1) A mechanical unit consisting of: (a) A spindle to rotate the inner ring of the test bearing. The test bearing is mounted on a mandrel attached to the spindle by a taper. (b) Spindle drive, consisting of electric motor, pulleys, belts, coupling and jackshaft. (c) A preloader for application of thrust load to the bearing. (d) A stand on which the various parts of the instrument are mounted. (2) A velocity sensitive pickup with a stylus contacting the outer ring of the bearing. (Author)
