Abstract
A reciprocating saw includes a housing defining a motor housing portion, and a motor positioned in the motor housing portion, the motor having a motor output shaft defining a rotational axis, and a motor activation switch within the motor housing portion and adjacent the motor. The reciprocating saw also includes a transmission is positioned downstream of the motor and has a sawbar connectable to a saw blade. The transmission converts a rotational input provided by the motor shaft to a reciprocating output of the sawbar along a reciprocating axis that is either coaxial or parallel with the rotational axis.
Claims23
A reciprocating saw comprising:
- a housing defining a motor housing portion;
- a motor positioned in the motor housing portion, the motor having a motor output shaft defining a rotational axis;
- a motor activation switch within the motor housing portion and adjacent the motor;
- and
- a transmission positioned downstream of the motor and having a sawbar connectable to a saw blade, the transmission converting a rotational input provided by the motor shaft to a reciprocating output of the sawbar along a reciprocating axis that is either coaxial or parallel with the rotational axis.
A reciprocating saw comprising:
- a housing defining a motor housing portion;
- a motor positioned in the motor housing portion, the motor having a motor output shaft defining a rotational axis;
- and
- a transmission positioned downstream of the motor, the transmission including
- a pinion driven by the motor output shaft,
- a ring gear meshed with the pinion and having a pin eccentrically coupled thereto, and
- a sawbar movable along a reciprocating axis that is either coaxial or parallel with the rotational axis, the sawbar having a slot in which the pin is received, the slot extending in a direction that is transverse to both the rotational axis of the motor output shaft and the reciprocating axis of the sawbar.
A reciprocating saw comprising:
- a housing defining a motor housing portion and a battery receptacle;
- a motor positioned in the motor housing portion, the motor having a motor output shaft defining a rotational axis;
- a transmission positioned downstream of the motor and having a sawbar connectable to a saw blade, the transmission converting a rotational input provided by the motor shaft to a reciprocating output of the sawbar along a reciprocating axis that is either coaxial or parallel with the rotational axis;
- a battery pack at least partially received within the battery receptacle;
- and
- a clamp assembly on the sawbar to which the saw blade is attachable,
- wherein the reciprocating saw defines an overall length between an end of the battery pack protruding from the battery receptacle and a distal end of the clamp assembly, wherein the overall length is about 12 inches or less, and wherein the motor housing portion defines a maximum width of about 2.5 inches or less.
