摘要： A power wrench includes a housing divided into two parts which are rotatable relative to each other: a first part including a handle and a transverse section lodging a rotation motor, and a second part including a reduction gearing, an output shaft and a rigidly attached and laterally extending reaction bar. A swivel connection is provided between the housing parts and includes an angle sensor arranged to generate signals in response to relative angular movements between the housing parts, and a power control unit communicates with the angle sensor and is arranged to at least substantially reduce the motor power as a pre-set maximum angular movement between. the housing parts is exceeded as the motor is started.

摘要： A power wrench including a housing, a rotation motor, a reduction gearing connecting the motor to an output shaft, and a separate gearing casing which is rotatively and detachably mounted on the housing and supporting the output shaft. The reduction gearing is divided into a first gearing stage located in the housing and a second gearing stage located in the separate gearing casing. The first gearing stage and the second gearing stage are interconnected via an intermediate spindle, and the motor is connected to the first gearing stage via a hollow drive shaft surrounding the intermediate spindle and an angle gear. A torque sensor is associated with the first gearing stage in the form of strain gauges mounted on an elastically deformable sleeve connecting a ring gear of the first gearing stage to the housing.

摘要： A power tool includes a power unit with a rotation motor, and a reduction gearing, wherein the reduction gearing includes a set of interchangeable gearing units attachable one at a time to the power unit and having different operational characteristics including different total gear ratio and torque capacity. Each gearing unit has an electronic identification device programmed with data specific for each gearing unit, such as total gear ratio, torque range, and relating to compatibility of the gearing unit with a certain power unit. The power unit includes an electronic operation control unit programmed with a number of different operation parameter sets each intended for a specific one of the gearing units, and a circuit for communicating with a gearing unit attached to the power unit to determine whether there is compatibility and which parameter set is applicable.
