Epicyclical gear systems are typically equipped withstraddle-mounted planetary idlers and are supported by pins on theinput and output sides of a carrier. These carriers can be eitherone-piece or two-piece carrier designs. Traditionally many of thehigher power rated epicyclic gear systems use cylindrical rollerbearings to support the planetary gears. This paper willdemonstrate that using a preloaded taper roller bearing in anintegrated package should be the preferred choice for thisapplication to increase the bearing capacity, power density, andfatigue life performance. Based on DIN281-4 calculations, thispatented [1], fully integrated solution allows for calculatedbearing fatigue lives to be 5 times greater than a non-integratedsolution and more than 1.5 times greater than a semi-integratedsolution, without changing the planet gear envelope.
