Abstract
A gearbox assembly for a turbine engine. The turbine engine includes a drive shaft and a fan shaft. The gearbox assembly includes a first gear, a second gear, an output, and a journal pin. The first gear is connected to the drive shaft. The second gear is supported by a planet carrier. The output is connected to the fan shaft. Torque is transferred from the drive shaft of the core turbine engine to the fan shaft through the gearbox assembly. The journal pin is inserted into the planet carrier. The second gear rotates about the journal pin. A coupling of the journal pin and the planet carrier is characterized by an interference ratio greater than a minimum interference ratio of 1.0e-5.
