Power takeoff devices (PTOs) are useful for mounting on transmissions and for performing, directly or indirectly, useful work via the mechanical energy generated by the PTO's rotatable output shaft. Systems and methods for reducing PTO gear rattle include a moveable input gear engaging and intermediate to an output gear and a transmission gear. The input gear is carried on an input gear carrier moveable such that the input gear centerline moves along a plane substantially perpendicular to a plane running between the centerlines of the output and transmission gears. The input gear travel is limited by the output and transmission gears such that the input gear is biased to engage at least one of the output gear and the transmission gear, thereby reducing or eliminating gear rattle from overly loose engagement between meshing teeth on the input gear and the transmission gear or output gear.

Systems and methods for abatement of gear rattle by linear deflection

PTO systems having reduced gear rattle are disclosed. Embodiments include a PTO having an input gear and an intermediate gear engaging the input gear. The intermediate gear rotates about fixed rotational axis. The input gear is attached to the intermediate gear by a support whereby the rotational axis of the input gear is capable of pivoting about the rotational axis of the intermediate gear at a fixed distance, following an arcuate path. The input gear is configured to engage a transmission gear, and biased to pivot toward the transmission gear, thereby reducing or eliminating gear rattle from overly loose engagement between meshing teeth on the intermediate and transmission gears.
