Abstract Details

2009, Master of Science, Ohio State University, Mechanical Engineering.
In this study, an accelerometer-based measurement method is proposed for measurement of motions of parallel-axis gears in torsional, translational and rotational directions. This method uses a family of tri-axial accelerometers that are mounted on a shaft flange at a given radius. Acceleration signals from the accelerometers are processed based on a novel formulation to quantify the motions of a gear in the torsional, rotational (rocking), transverse (line-of-action and off-line-of-action) and axial directions. With the similar instrumentation implemented on the mating gear, the dynamic transmission error of the gear pair is also measured. This measurement system is applied for example to spur and helical gear pairs held by different shafts representative of different support compliances. The transverse motions of the spur pinion in the line-of-action direction, as well as line-of-action, rocking and axial motions of helical gears are shown to be significant when they are supported compliantly. At the end, the same experiments are simulated by using a previously developed gear-shaft-bearing dynamics model to identify the shapes of the modes excited and to show the agreement between the predicted and measured forced responses.
