... This paper examines the effect of dynamic propeller loads on the axial location of the knuckle point in a double sloped aft sterntube bearing (ASTB), as found in a typical marine slow-speed direct drive diesel engine powertrain. The so-called double sloped geometry is formed inside a bearing...
