    摘要: A power tool with a flywheel, an activation arm, a driver, a cam and a clutch. The activation arm can have a first arm, a second arm, which can be pivotally mounted to the first arm, and a roller that can be coupled to the second arm. The driver can be disposed between the roller and the flywheel. The cam can be moveable in a predetermined direction for causing the activation arm to rotate about a pivot to drive the roller against the driver so that the driver frictionally engages the flywheel. The clutch can cooperate with the cam to inhibit the cam from moving in a direction opposite the predetermined direction in response to a reaction force that is applied by the driver onto the activation arm.

    摘要: A power tool having an integrated control system includes a workpiece supporting surface, a cutting instrument extendable above the workpiece supporting surface, a guard assembly securable above the workpiece supporting surface for covering at least a portion of the cutting instrument, the guard assembly having a first state for providing a first level of protection and a second state for providing a second level of protection, a motor coupled with the cutting instrument, and a power switch operable for starting the motor for driving the cutting instrument. The power tool includes a control system in communication with the guard assembly for determining if the guard assembly is in the first state or the second state. Before the motor is started, the control system automatically disables the motor if it determines that the guard assembly is in the second state. The control system includes a bypass switch for enabling starting of the motor when the guard assembly is in the second state.

    摘要: A power tool for drilling a hole in a workpiece made of wood or a wood material. The power tool generally includes a tool housing defining a handle and a motor contained within the tool housing that includes an output shaft that spins about a motor axis. A gear housing is connected to the tool housing. An output spindle is supported for rotation about a spindle axis in the gear housing. The spindle axis is disposed about ninety degrees from the motor axis. A gear portion on the output shaft is engaged to a gear portion on the output spindle. The motor and the gear portions are configured to rotate the output spindle at a speed in range from about five thousand revolutions per minute to about twenty-five thousand revolutions per minute. A cutting member is connected to the output spindle. The cutting member includes fluted cutting blades. A carriage assembly includes a base member and a head member connected by a first post having a first compliant member and a second post. The head member slides relative to the first and second posts and against a force exerted by the first compliant member when the head member is moved toward the base member to pass the cutting member through the base member to engage the workpiece. The base member includes a generally planar face on a bottom surface of the base member that is generally perpendicular to the spindle axis.

    摘要: A control scheme is provided for a power tool having a rotary shaft. The control scheme includes: monitoring rotational motion of the tool generally about a longitudinal axis of the shaft; detecting a condition of the tool based on the rotational motion of the tool; and controlling torque imparted to the shaft upon detecting the tool condition, where the torque is inversely related to an angular displacement of the tool about the longitudinal axis of the shaft.
