The reciprocating saw incorporates a counterbalanced reciprocating drive having a jackshaft on which primary and secondary wobble plates are mounted. The wobble plates drive reciprocating saw spindle and a concentric counterweight in opposite directions to cancel out the induced vibrations. The spindle reciprocates in a bearing sleeve having a slot through which the primary wobble arm projects to drive the spindle. The counterweight slides on the outside of the sleeve and has a slot which slides over the primary arm. The secondary arm drives the counterweight. The arms are out of alignment to permit their strokes to overlap without collision. The wobble plates are angled out of 180 DEG so the spindle and counterbalance reverse at the same time. The cutting stroke and speed are increased and vibration is insignificant. The drive has many other uses. |
