Systems and methods of operating power tools. The method includes receiving a command to start a recording mode at a first electronic processor of a first power tool, and receiving at the first electronic processor, a measured parameter from a sensor of the first power tool while a first motor of the first power tool is operating. The method also includes generating a recorded motor parameter by recording the measured parameter, on a first memory of the first power tool, when the first power tool operates in the recording mode, and transmitting, with a first transceiver of the first power tool, the recorded motor parameter. The method further includes receiving the recorded motor parameter at an external device, transmitting the recorded motor parameter to a second power tool via the external device, and receiving the recorded motor parameter via a second transceiver of the second power tool.

A torque transmission mechanism transmits a torque produced by a rotation of a driving shaft to an output shaft. A clutch mechanism is provided between a motor and the torque transmission mechanism. The torque transmission mechanism includes a magnet coupling including a driving magnet member coupled to the driving shaft side and a driven magnet member coupled to the output shaft side. The driving magnet member and the driven magnet member are arranged such that magnetic surfaces on each of which S-pole magnets and N-pole magnets are alternately arranged face other. The clutch mechanism transmits the torque produced by the rotation of the driving shaft to the driving magnet member but does not transmit a torque the driving magnet member receives from the driven magnet member to the driving shaft.

A coupling member for an electric power tool is provided. The coupling member can keep a hanging member being held, even when a holding portion of the tool for holding the hanging member breaks. A coupling member for an electric power tool is configured to hook a hanging member to an electric power tool main body and can fasten the electric power tool main body therein, when one of its parts opens or closes. Further, this coupling member can be attached to the electric power tool main body with the electric power tool main body fastened therein or removed therefrom. Further, the hanging member can be hooked to the coupling member.

A tool with two sequential gear trains and gear carrier assemblies adapted to be recessed into internal gears. The internal gear assembly also prevents rotation of the internal gear assembly relative to a housing of the tool. For example, the internal gear assembly can include a first gear train and second gear train sequentially coupled to the first gear train, wherein a first ring gear and first planet gears of the first gear train are substantially similar to a second ring gear and second planet gears of the second gear train.

A screwing device includes a screwdriver and a connection element for coupling the screwdriver to a robot arm. The connection element has a first robot-side transmission element, a second tool-side transmission element, a restoring element arranged between the first and second transmission elements, and a distance measuring element. The two transmission elements can be moved towards each other against a restoring force of the restoring element in an actuation direction. The distance measuring element measures a distance that represents the spacing between the transmission elements in the actuation direction and is used to control the actuating force acting on the screwdriver.

Inserts disposed in a housing of a pneumatically or hydraulically powered tool having a motor adapted to rotate a drive lug in either of first and second rotational directions. The insert is composed of a material resistive to creep and/or stress relaxation. The insert contacts fasteners applying a clamping force to the tool and remove the housing from the load path of the clamping force, thereby reducing the possibility of fluid leaks.

An electric power tool includes an electric motor with a motor gear, an output shaft with an input gear, a coupling that connects the motor gear to the input gear, and a housing that houses the motor, the motor gear, the coupling and the input gear. The coupling includes a shaft portion and two connective portions arranged at opposite ends of the shaft portion for connection to the motor gear and input gear, respectively. The motor gear and the input gear, each, have a cambered profile allowing a tilting movement of the coupling with respect to an axial position of one of the motor gear and the input gear that has a cambered profile.

A power tool includes a wrench head having a rotary socket, and a spanner tool mounted in the rotary socket, wherein the rotary socket grips a first component and the spanner tool grips a second components, the first and second component being adjacent.
