Power tool, in particular a pipe press, including a drive, an output shaft, a threaded spindle drive and a linear actuator, wherein a torque generated by the drive is transmissible via the output shaft, and the threaded spindle drive connected to the output shaft, to the linear actuator. The power tool includes an eccentric transmission device for a torque adaptation between the drive and the threaded spindle drive, wherein the eccentric transmission device includes a drive eccentric, which is drivable by the drive, an eccentric gear, which is drivable by the drive eccentric, and a compensating coupling, which is drivable by the eccentric gear and which serves for transmitting torque from the eccentric gear to the output shaft.

Eccentric transmission for a power tool

Power tool, in particular a pipe press, including a drive, a transmission device, a threaded spindle drive and a linear actuator, wherein a torque generated by the drive is transmissible via the transmission device and the threaded spindle drive to the linear actuator. The power tool includes a coupling device for converting a rotational movement generated by the transmission device into a linear movement, to be transmitted to the threaded spindle drive, from the transmission device to the threaded spindle drive, wherein at least one spring element for reducing torsion acting on the coupling device is comprised.

Spring element and coupling device

Power tool, in particular a hammer drill, including a housing, a tool fitting for receiving and holding a tool, an impact device for producing and transmitting impact pulses to the tool, and a rotation device for producing and transmitting a torque to the tool, wherein a working axis passing through the impact device is provided. The power tool includes a first drive unit having a first axis of rotation for driving the rotation device and a second drive unit having a second axis of rotation for driving the impact device, wherein the first and second drive units are arranged in such a way relative to one another in the housing that the first axis of rotation of the first drive unit is arranged at a first angle to the second axis of rotation of the second drive unit and at a second angle to the working axis.

Power tool having two motors

Hand-held power tool having a tool fitting for holding a striking and rotating tool on a working axis, an electric motor, an impact mechanism, which has a striker moved periodically along the working axis, and having a rotary drive, which drives a spindle bearing the tool fitting in a rotating manner about the working axis, the rotary drive having a step-down eccentric gear mechanism, connected to the electric motor, and the spindle being coupled to the eccentric gear mechanism.
