  • The Importance of Bearing Selection on Gearbox

    Gearboxes often have spherical roller bearings installed on slower speed reduction shafts which is interesting from a bearing application perspective. Gearboxes are accurate by design. Gear mesh, backlash and alignment are critical to gear life and reliable operation. Shaft design must maintain this accuracy without deflection. Housing bore alignment must ensure the shaft maintains the gear ...

  • Solving Gearbox Gear Problems – Neale Consulting

    IntroductionGear Mis-AlignmentGear BearingsThermal InstabilityTorsional Lateral VibrationUnexpected LoadsLubrication and ContaminationA review of all gear and gearbox failures investigated by NCEL showed that the failure sequence frequently starts with a bearing, rather than a gear. Fig. 1 summarises the results, with bearings being the apparent root of about half of all gear failures.Figure 1. Shows distribution of gearbox failure root causes.This may at first sight seem surprising, since rolling bearings (used in the majority of gearboxes) seem to have a relatively easy job compared to the gears. The gears have substantia...
