Abstract
A force and moment canceling reciprocating mechanism for a power-driven tool may include a transmission including an input gear assembly and an output gear assembly, coupled to a reciprocating mechanism. The input gear assembly may include a first input gear coaxially aligned with a second input gear. The output gear assembly may include a first output gear coaxially arranged with a second output gear. The reciprocating mechanism may be coupled to the output gear assembly, to convert rotational motion to linear motion, for output to an output accessory of the tool. One or both of the first and second input gears may include counterweights, or counterweight masses, and one or both of the first and second output gears may include counterweights, or counterweight masses. The counterweighting of the input and output gear assemblies may provide for the cancelation of forces and moments generated by the operation of the motor and the transmission, and the reciprocal motion of the reciprocating mechanism.
