Abstract
A drive gear assembly rotatably drives a driven gear of an engine component. The drive gear assembly comprises a drive shaft extending longitudinally along an axis. A main drive gear is operatively coupled to the drive shaft and a scissor gear is aligned coaxially with the main drive gear. A scissor spring is disposed and operatively coupled between the main drive gear and the scissor gear and biased therebetween wherein the main drive gear and the scissor gear rotate about the axis relative to each other. An isolation mechanism is operatively coupled between the main drive gear and the drive shaft for absorbing impulse loads generated by the driven gear when engaged with the main drive gear.
