    摘要： A power tool is disclosed. The power tool has a pneumatic striking mechanism, which has a striking device that acts percussively along a working axis. A motor serves as the drive. A gear mechanism has a driving gear wheel and a driven gear wheel, where the driving gear wheel meshes with the driven gear wheel and at least the axis of rotation of the driven gear wheel is inclined to the working axis. The driving gear wheel is fabricated of metal and the driven gear wheel is fabricated of a carbon-fiber reinforced plastic.

    摘要： A reduction gear mechanism, incorporating a speed changing mechanism, for use with a motor-driven drill. The mechanism includes at least one planetary speed reducer having a sun gear to which rotation of an electric motor is transmitted, a plurality of planet gears arranged around the sun gear and engaged with the sun gear, an internal gear internally engaged with the planet gears, and a planet gear holding plate which pivotally supports the planet gears on one side of it and has an output shaft on the other side of it. The internal gear of at least one planetary speed reducer includes a cylindrical internal gear. The reduction gear includes mechanisms for locking the cylindrical internal gear to prevent rotation of the cylindrical internal gear and for engaging the cylindrical internal gear with the planet gear holding plate so that the cylindrical internal gear and the planet gear holding plate rotate as a single unit.
