The present invention relates to a power takeoff (PTO) device. More specifically, the present invention relates to a PTO with a novel bolted joint assembly securing the housing of the PTO to a transmission housing, whereby the bolted joint assembly is easier to assemble correctly and more robust than conventional bolted joint assemblies used with conventional PTO housings. The preferred embodiment of the invention comprises elongated fasteners affixing or securing the PTO housing to the transmission housing. Such elongated fasteners provide easier access to the fastener head with standard tools, while providing significantly greater fastener stretch that reduces or prevents vibration loosening of the PTO housing.

The present invention relates to a dampened gear system for reducing gear rattle. More specifically, a dampened gear system includes a first gear vibrationally isolated from a second gear. At least one damper prevents rotational engagement between the first gear and second gear until a rotational load is applied. When a rotational load is applied, the at least one damper is compressed, resulting in at least one lug on the second gear contacting an engagement surface on the first gear, allowing the rotational load to be mechanically transferred from one gear to the other gear.
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 an input gear carried on a shaft sleeve mounted on a shaft extending between opposing spaced apart walls of a PTO housing. The shaft sleeve is moveable in an axial direction along the shaft, the travel of the shaft sleeve in each direction being limited by contacting the respective wall. The shaft sleeve is biased to remain spaced apart from the walls, thereby reducing or eliminating gear rattle.
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.

Embodiments of the present disclosure provide an improved clutch-brake for a PTO unit. In accordance with a first embodiment of the present disclosure, a dual direction clutch-brake with a clutch cup is disclosed. When moved in one direction, the clutch cup engages a clutch pack resulting in the input shaft being engaged with the output shaft. When the clutch cap is moved in the opposite direction, the clutch cup engages a breaking member, for example a cover or casing of the PTO unit, which applies a force to the output shaft opposite to the direction of rotation and thereby stops the output shaft from rotating.
