Torsional Characteristics Measurement of a Gearbox

Abstract

Torsional characteristics of the gearboxes are important for kinematic and dynamic behaviour of the whole drive train, especially the resonances. Measured values are used as an input for further dynamic calculations. The measurement of the torsional stiffness and backlash is carried out. For this purpose the incremental rotary sensors and magnetic sensor of position are used. The results shown the behaviour of the torsional stiffness of the gearbox during loading. Furthermore the backlash of the gearbox is measured.

“…they measured the final drive ratio lash in a static fashion by mechanically constraining driveline components but do not note how the measurement was made, just that a static technique was used [6]. Lash can also be measured in a dynamic fashion such as measuring the number of incremental rotations an input shaft achieves before the output shaft begins to rotate as well [63].
