摘要:
A power driver (500) may include a motor (590) that rotates upon receiving an input current. A tool chuck (550) may have chuck jaws to hold an accessory. The tool chuck (550) may be coupled to the motor. A power take off mechanism (510) may be connected between the motor (590) and the tool chuck (550). The power take off mechanism (510) may be adjustable into a CHUCK MODE to one of open and close the chuck jaws while the motor rotates. An electronic clutch (540) may interrupt the input current to the motor (590) if the power take off mechanism (510) is in the CHUCK MODE and if the input current exceeds a trip value.
摘要:
A power tool (10) includes a housing (12, 14), a motor (26), an output member (11) driven by the motor, and a reaming attachment (214) coupled to the output member. The reaming attachment has a front end portion selectively driven in rotation by the output member (11) to drive a fastener into a workpiece, and a reaming portion selectively driven in rotation by the output member to remove material from an end surface of a conduit. A rotational motion sensor (22) in the housing (12, 14) is operable to detect rotational motion of the housing about an axis. A controller (24) receives a signal indicative of rotational motion from the sensor, determines a direction of the rotational motion of the housing (12, 14), and drives the motor in a direction corresponding to the direction of rotational motion of the housing.

A power tool includes a tool body having an output member that drives an accessory. An end effector is coupled for rotation with the output member. A light source is disposed on the end effector. A primary coil assembly is configured on the tool body and mounted concentric to the output member. The primary coil assembly includes a primary coil that is electrically connected to a power source of the power tool. A secondary coil assembly is configured on the end effector and mounted concentric to the output member. The secondary coil assembly includes a secondary coil that is electrically connected to the light source. Current flowing through the primary coil creates a magnetic field that causes current to flow through the secondary winding and power the light source.

A power driver may include a housing, a tool chuck (50) and a power take off mechanism (10). The tool chuck (50) may have an input shaft (60) mounted for rotation on the housing. The input shaft (60) may support chuck jaws. A chuck actuating shaft (64) may be mounted for rotation on the input shaft (60). The power take off mechanism (10) may be connected to the tool chuck (50). The power take off mechanism (10) may be adjustable into a DRILL DRIVE MODE to rotationally drive the input shaft (60) and the chuck actuating shaft (64) together as a unit, and a CHUCK MODE to rotationally drive the chuck actuating shaft (64) relative to the input shaft (60). The power take off mechanism (10) may be internal of the housing. The power take off mechanism (10) in the CHUCK MODE may rotationally fix the input shaft (60) to the housing.
