Patent ID: 8534378

Claim:
A transmission, in particular for electric hand-held power tools, with a drive gear ( 23 ), which is driven by a drive, a driven gear ( 14 ), which meshes with the drive gear ( 23 ) and drives a spindle ( 2 ), and with a locking device, via which the spindle ( 2 )—for the purpose of releasing and attaching tools—is capable of being coupled such that the spindle is non-rotatable relative to a circumferential wall ( 26 ) enclosing the locking device, which opens automatically when torque is transferred from the drive to the spindle ( 2 ), and which blocks automatically when torque is transferred from the spindle ( 2 ) to the drive, the driven gear ( 14 ) being rotatable relative to the spindle ( 2 ) around a limited circumferential angle, and a driving element ( 17 ) is non-rotatably coupled with the driven gear ( 14 ) in order to transfer torque to a counter-element ( 18 ) located on a clamping disk ( 6 ) of the locking device that is non-rotatably coupled with the spindle ( 2 ), wherein the locking device includes at least one resilient damping element ( 20 ) located between the driving element ( 17 ) and the counter-element ( 18 ) in the circumferential direction, wherein the clamping disk ( 6 ) includes, on an outer circumference, at least one first recess ( 9 ), which widens radially in a first circumferential direction, a first blocking element ( 11 ) that is movable in the radial direction and in both circumferential directions that is located in the first recess ( 9 ) and blocks the spindle ( 2 ) in the first circumferential direction when torque is transferred from the spindle ( 2 ) to the drive by clamping between an inner wall ( 25 ) of the first recess ( 9 ) and the circumferential wall ( 26 ), wherein at least one finger ( 16 ) that is non-rotatably connected with the driven gear ( 14 ) is provided in order that when the driven gear ( 14 ) is driven, the finger ( 16 ) pushes the first blocking element ( 11 ) in the circumferential direction out of a blocked position and into a released position, and holds the first blocking element in the released position, and wherein the first blocking element ( 11 ) extends axially out of said blocking element's particular recess ( 9 , 10 ) in the direction towards the finger ( 16 ).
