EDDY CURRENT DAMPER FOR POWER TAKE-OFF GEAR RATTLE ABATEMENT

Abstract:

A power take-off includes a housing that is adapted to be supported on a source of rotational energy, an input mechanism that is supported within the housing and adapted to be rotatably driven by the source of rotational energy, and an output mechanism that is supported within the housing and rotatably driven by the input mechanism. At least one of the input mechanism and the output mechanism includes a pair of mating gears. An eddy current damper is supported within the housing and configured to exert a drag torque on either or both of the mating gears during operation of the power take-off. The eddy current damper may provide a variable amount of such drag torque, a constant amount of such drag torque, or a combination of both.
