摘要： A reciprocating saw (10) including a housing (12), a spindle (14) mounted for reciprocation relative to the housing and having a front end adapted to support a saw blade (18), the spindle being movable through a cutting stroke and a return stroke, a motor (20) for moving the spindle in a reciprocating fashion, and a reciprocating member (40, 50) interconnecting the motor with the spindle. The motor and the spindle define a drive force path from the motor to the spindle and passing through drive force bearing components of the reciprocating saw, and wherein at least part of the reciprocating member is in the drive force path. The reciprocating member is configured to counterbalance the spindle. A pivot body (50) interconnects the spindle with the motor. A shock absorber (66') is operatively positioned between the motor and the front end of the spindle, and is at least partially mounted within the spindle.

摘要： A reciprocating saw (15, fig 1) comprises a housing (20, fig 1), a motor, and a spindle (25, fig 2) supported for reciprocating motion relative to the housing. A counterweight assembly 135 is supported for movement relative to the housing, which substantially balances at least a portion of the movement of the spindle. An adjustment assembly 40 operates to adjust the movement of the counterweight relative to the housing. Preferably the adjustment assembly is connected to a rotary member. The adjustment assembly may define an eccentric axis (3-3, fig 13) at a position relative to the rotary axis (1-1, fig 13) of the rotary member, to adjust the stroke length of the spindle. An arm member 30 may be provided that has a drive end connected to the rotary member along the eccentric axis of the adjusting assembly, and a spindle end connected to the spindle.

摘要： A reciprocating saw comprises a motor positioned within a housing. The motor includes a pinion 96. A drive mechanism within the housing includes a gear 100 coupled to and driven by the pinion, a hub 104 coupled for rotation with the gear. A spindle 116 reciprocates relative to the housing assembly, and a connecting rod 112 extends between the hub and the spindle to transmit rotation of the hub into reciprocation of the spindle. A slip clutch assembly 132 transmits drive force from the gear to the hub, and includes a first disk 136 coupled to the gear, a second disk 140 coupled to the hub, the couplings preferably being by splines. A biasing member 144, preferably in the form of a spring disc, is positioned between the hub and the gear to bias the first and second disks into frictional engagement. The clutch assembly also includes a fastener extending through the gear and threadingly engaging the hub to couple the hub to the gear and pull the hub toward the gear to preload the biasing member and clutch members. The clutch members, hub and biasing member are preferably located in an opening 108 in the gear.

摘要： A power tool includes a housing, a motor supported in the housing, a transmission operably coupled to the motor, an output shaft rotatable about a central axis, a clutch mechanism including a resilient member, and a clutch mechanism adjustment assembly having a first ring rotatable about the central axis. The first ring includes a cam surface spaced from the central axis in a radial direction. The clutch mechanism adjustment assembly also includes a second ring coaxial with the first cam ring and in facing relationship with the cam surface, and a cam member disposed between the cam surface and the second ring. In response to rotation of the first ring relative to the second ring, the cam member engages the cam surface to displace the first ring relative to the second ring and compress the resilient member to increase the amount of torque transferred to the output shaft.
