摘要： A power tool includes: a housing having a handle configured to be grasped by a user; a motor supported by the housing and defining a motor axis; a driving gear rotated by the motor about the motor axis; a driven gear defining a rotation axis that is parallel to the motor axis, the driven gear engaging the driving gear to be rotated by the driving gear about the rotation axis; a crankshaft coupled to and rotatable with the driven gear; a counterweight having a first yoke coupled to the driven gear to translate rotation of the driven gear into reciprocating motion of the counterweight; and a spindle having a second yoke coupled to the crankshaft to translate rotation of the driven gear into reciprocating motion of the spindle, wherein the counterweight and the spindle reciprocate opposite one another.

摘要： An oscillating power tool including a housing, a motor including a drive shaft rotatable about a motor axis, an output spindle configured to be driven by the motor and journaled for oscillating rotation about an oscillation axis, and a drive mechanism. The drive mechanism is configured to convert rotation of the drive shaft into oscillating rotation of the output spindle about the oscillation axis and includes an eccentric member and a forked member. Oscillating rotation of the forked member has an angular amplitude about the oscillation axis. The eccentric member is movable with respect to the forked member to change the angular amplitude of oscillating rotation of the forked member. An amplitude adjustment actuator is configured to move the eccentric member to change the angular amplitude of oscillating rotation of the forked member. The amplitude adjustment actuator defines a receptacle. At least a portion of the forked member is disposed in the receptacle.

摘要： A reciprocating saw includes a housing assembly and a motor positioned within the housing assembly. The motor includes a pinion. A drive mechanism is positioned within the housing assembly and includes a gear driven by the pinion, a hub coupled to the gear, a spindle, and a connecting rod. A clutch assembly is coupled to the drive mechanism to selectively transmit drive force form the gear to the hub. The clutch assembly includes a first disk coupled to the gear, a second disk coupled to the hub, a biasing member, and a threaded fastener. The biasing member is positioned between the hub and the gear to bias the first and second disks into frictional engagement. The threaded fastener extends through the gear and threadably engages the hub to couple the hub to the gear. Tightening the threaded fastener pulls the hub toward the gear to preload the biasing member.

摘要： A surgical sagittal saw cartridge that includes a guide bar formed from an inner plate and opposed outer plates, the inner plate defining a head. The cartridge has a blade that is disposed against the head of the inner plate. The inner plate may comprise an inner tine and/or two opposed outer tines. The inner tine may be formed to define the head against which the blade is disposed. The outer tines may extend distally so as to define a space between the outer tines in which the blade is seated.

摘要： A reciprocating tool includes a housing, a support body, a slider, a motor, a driving mechanism, a first biasing member, a manipulation member and a first change mechanism. The housing has a first axis that defines a front-rear direction of the reciprocating tool. The support body is supported within the housing. The slider is supported by the support body to be linearly movable. The driving mechanism is operably coupled to the slider and configured to reciprocally move the slider relative to the support body using power of the motor. The first change mechanism is operably coupled to the manipulation member and configured to selectively enable and disable the first biasing member to bias the slider in response to manipulation of the manipulation member. When biasing of the slider by the first biasing member is enabled by the first change mechanism, the first biasing member biases the slider downward.

摘要： Systems and methods for configuring a power tool. One system includes a power tool communication system that includes an external device and a power tool. The external device includes a user interface configured to receive a first selection to enable a feature of a power tool, and receive a second selection of a threshold of a motor characteristic of the power tool. The power tool includes a motor within a housing. The power tool receives the selected feature and the selected threshold from the external device. The power tool includes a sensor configured to monitor the motor characteristic of the motor. The power tool further includes an electronic processor that controls the motor to operate according to the selected feature and adjusts an operating parameter of the motor when the motor characteristic is determined to cross the selected threshold.
