摘要： A torque wrench for multiple bolts or nuts comprises multiple drive spindles that are arranged annularly around a center and are equipped or able to be equipped at the end with respective torque-applying tools, and a ratchet drive, associated with each drive spindle and driven by means of a hydraulic piston drive, for driving the drive spindles. The torque wrench for multiple bolts or nuts also comprises an actuator unit for inducing a rotary movement in the drive spindles, having an actuating wheel mounted rotatably about the axis of the center of the annular arrangement of the drive spindles as drive wheel, which drives respective output wheels fitted on the drive spindles, wherein the driving movement of the actuating wheel is transmitted to the drive spindle via respective torque limiters.

摘要： A torque wrench including a head, a handle, a primary beam, a secondary beam, and a torque adjustment mechanism. The primary beam couples the head and the handle for co-rotation about the rotational axis and the primary beam includes a first end adjacent the head and a second end adjacent the handle. The secondary beam is coupled to the head for rotation with the head about the rotational axis and the secondary beam is movable relative to the primary beam and the handle. The torque adjustment mechanism adjusts a torque setting of the primary beam relative to the secondary beam. The torque adjustment mechanism includes a thumb adjustment wheel that a user rotates about a first axis to adjust the torque setting by moving the second end of the primary beam relative to the handle along a second axis offset from the first axis.

摘要： A rotating power tool is provided. The rotating power tool may include a bevel gear set having a bevel gear and a conductive spiral disposed on the bevel gear. The conductive spiral may be configured to, in response to the bevel gear deforming due to a torque being applied to the bevel gear, change a resistance of the conductive spiral. The rotating power tool may further include an antenna electrically connected to the conductive spiral. The antenna may be configured to emit an output signal at a frequency that is based on the resistance value of the conductive spiral. The frequency of the output signal may be indicative of an amount of torque being applied to the bevel gear.

摘要： A flexible bit holder may include a drive body having a receiving orifice formed therein, a drive body having a shank and a flexion assembly. The receiving orifice may be configured to receive a bit, and the shank may be configured to interface with a driver to receive rotational energy from the driver. The flexion assembly may be disposed between at least a portion of the drive body and the driven body to operably couple the drive body and driven body. The flexion assembly may be configured to transfer torque applied to the driven body by the driver to the drive body. The flexion assembly may be formed of flexible material such that the drive body is rotatable relative to the driven body about a common axis of the drive body and the driven body.

摘要： A transducer assembly for use in a power tool including a housing, a motor, an output shaft that drives a workpiece about a central axis, and a transmission. The transducer assembly includes a transducer positioned between the motor and the transmission. The transducer including an inner hub being rotationally affixed to the housing, an outer rim affixed to a rotatable component of the transmission, a plurality of webs extending radially outward from the inner hub to the outer rim, and a sensor affixed to each of the webs for detecting strain of each of the webs in response to a reaction torque applied to the transmission from the output shaft. A width of each of the webs gradually tapers from at least one of the outer rim or the inner hub toward a midpoint of each of the webs in a direction perpendicular to the central axis.
