Abstract
A reciprocating power tool may include a driving system including a motor and a transmission received in a housing to drive a reciprocating mechanism. A selection mechanism may provide for selection of an operation mode of the reciprocating tool, including a linear mode of operation and at least one orbital mode of operation. Motion of a reciprocating shaft of the reciprocating mechanism may be guided by a guide bracket that is fixed in the housing and an orbit bushing that is movably coupled in the housing. In the linear mode of operation of the tool, the bushing is in a first position relative to the guide bracket. In an orbital mode of operation of the tool, the bushing is moved to a second position relative to the guide bracket.
Claims19
A reciprocating power tool, comprising:
- a housing;
- a driving system including a motor and a transmission received in the housing;
- a selection mechanism moveably coupled to the housing and configured to provide for selection of an operation mode of a plurality of operation modes of the reciprocating power tool;
- and
- a reciprocating mechanism received in the housing, the reciprocating mechanism including:
- a guide bracket fixed in the housing;
- a bushing coupled to the selection mechanism and movably coupled in the housing;
- and
- a reciprocating shaft having a first end portion thereof coupled to the transmission and movably coupled to the guide bracket and an intermediate portion thereof movably coupled in the bushing, wherein the reciprocating shaft is configured to move in a reciprocating motion in response to a force transmitted thereto from the motor and the transmission.
A reciprocating power tool, comprising:
- a housing;
- a driving system including a motor and a transmission received in the housing;
- a selection mechanism moveably coupled to the housing and providing for selection of one of a plurality of modes of operation of the reciprocating power tool, the selection mechanism including:
- a selection knob accessible from an exterior of the housing;
- and
- a selection arm coupled to the selection knob at an interior of the housing;
- and
- a reciprocating mechanism received in the housing and coupled to the driving system and to the selection mechanism, the reciprocating mechanism including:
- a reciprocating shaft;
- a guide bracket fixed in the housing and configured to guide movement of a first end portion of the reciprocating shaft;
- a bushing coupled to the selection mechanism, movably coupled in the housing, and coupled to an intermediate portion of the reciprocating shaft, wherein a position of the bushing relative to the guide bracket is changed in response to a manipulation of the selection mechanism;
- and
- a yoke having a first end portion thereof coupled to the first end portion of the reciprocating mechanism and a second end portion thereof coupled to an eccentric pin on an output gear of the transmission, wherein the yoke receives a rotational force of the gear and applies a linear force to the reciprocating shaft, wherein the reciprocating shaft is configured to move in a reciprocating motion in response to rotation of the output gear and the corresponding linear force transmitted thereto by the yoke.
