Abstract
A tool coupling device for coupling a tool can comprise a drive shaft for coupling to the drive, an output shaft for coupling to the tool, the output shaft being rotatable about a central axis (A), a transmission unit connected between the drive shaft and the output shaft and translating a rotational movement of the drive shaft at an input speed (nS) into a rotational movement of the output shaft at an output speed (nW) greater than the input speed (nS) and a non-rotating housing, wherein the transmission unit, and at least a part of the input shaft and a part of the output shaft that are both coupled to the transmission unit, are arranged within the housing, wherein the drive shaft is rotatably mounted on the housing; and wherein the output shaft is rotatably supported solely on the input shaft and is not rotatably supported on the housing.
