in associated pockets 18 in top side of driving disk 15 via driving elements 17 the torque applied to driven gear 14 is transferred to counter elements of clamping disk 6 designed as pockets 18 the torque is transferred by driving elements 17 to radial walls 19 of pockets 18 in the installed state damping elements 20 u2014 with which vibrations in the drive train may be damped u2014 are located between radial walls 19 and driving elements 17 when torque is transferred the damping elements deform elastically and are clamped between walls 19 and driving elements 17 if the intention is to use transmission 1 shown e g in a drill with two directions of rotation it is advantageous when damping elements are also located between walls 21 of pockets 18 opposite to walls 19 and driving elements 17 driven gear 14 is supported on spindle 2 in such a manner that it may rotate freely in the upward axial direction driven gear 14 is held in its position by a snap ring 22 at the bottom driven gear 14 rests on clamping disk 6 driven gear 14 is driven via a drive gear which is designed as pinion 23 meshes with driven gear 14 and is driven by an electric motor drive via a shaft the function of the locking device which is composed of driving disk 15 with driving elements 17 clamping disk 6 with pockets 18 recesses 9 10 and blocking elements 11.
