Center Distance Influence on Gearbox Dynamics
Influence of Center Distance Variation on Noise In Compound Gearboxes
This article presents the analysis of center distance influence on gearbox dynamics, which is characterized by time-varying mesh stiffness. System-level dynamic analysis and a detailed mathematical transmission model presenting the center distance as a variable have been used to predict the gearbox noise behavior. The center distance variation in the mathematical model is simulated by utilizing the housing bore position tolerance, with the influence on the noise characteristic being studied. The housing bore positions were displaced by specifying finite displacements of bearings, which are supporting shafts in the gearbox model. Multiple conditions based on housing bore tolerance ranges have also been studied. The results obtained from this paper may be used in gearbox diagnostics, with the sensitivity of housing bore tolerance also able to be analyzed.
