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

A portable power toolhas a tool holderfor retaining a tool, a handle, an electric motor, and a drive train. The drive train couples the electric motorto the tool holder. The drive traincontains a planetary transmissionwith a planet carrierand a plurality of planet gears. At least one of the planet gearshas a cylindrical cutoutand the planet carrierhas a collarin the form of a circular arc that protrudes into the cutout
