Abstract
A reciprocating saw includes a motor, a lower gear case subassembly, and an upper gear case subassembly. The lower gear case subassembly includes a first driveshaft portion and a counterweight configured to be driven by the motor to reciprocate via the first driveshaft portion. The upper gear case subassembly includes a second driveshaft portion and a spindle configured to be driven by the motor to reciprocate via the second driveshaft portion. The first driveshaft portion is coupled to the second driveshaft portion by joining the upper and lower gear case subassemblies.
Claims15
A reciprocating saw comprising:
- a motor;
- a lower gear case subassembly including a first driveshaft portion, and a counterweight configured to be driven by the motor to reciprocate via the first driveshaft portion;
- and
- an upper gear case subassembly including a second driveshaft portion, and a spindle configured to be driven by the motor to reciprocate via the second driveshaft portion;
- wherein the first driveshaft portion is coupled to the second driveshaft portion by joining the upper and lower gear case subassemblies.
A reciprocating saw comprising:
- a motor defining a motor axis, the motor including a front end and a back end, the front end including a front face defining a first vertical plane, and the back end including a rear face opposite the front face, the rear face defining a second vertical plane parallel to the first vertical plane;
- a lower gear case subassembly including a first driveshaft portion, and a counterweight configured to be driven by the motor to reciprocate via the first driveshaft portion;
- and
- an upper gear case subassembly including a second driveshaft portion, and a spindle configured to be driven by the motor to reciprocate relative to the motor via the second driveshaft portion, the spindle being configured to reciprocate along a spindle axis parallel to the motor axis, the spindle including a rear end nearest to the motor;
- wherein the first driveshaft portion is coupled to the second driveshaft portion by joining the upper and lower gear case subassemblies;
- and
- wherein the spindle is arranged above the motor such that, as the spindle reciprocates forward and backward for each drive cycle, the rear end extends into a space defined between the first and second vertical planes during at least a portion of the drive cycle.
