It is well understood that friction is a fact of life. Any mechanical device with components in relative motion must cope with both the beneficial and detrimental aspects of friction in all of its forms. With regard to gearboxes, four specific types of friction must be accounted for in order to understand their potential impact on gearbox efficiency. These include friction that stems from the meshing of gear sets, bearing friction, seal friction and viscous friction, which occurs due to lubricant action.
Knowing the relative impact of these friction variables—in addition to understanding no-load torque and thermal considerations—will help you select the most efficient gearbox for your next application. Read our latest white paper to find out everything you need to know about gearbox friction.
