Patent ID: 8011445

Claim:
A portable power tool, comprising: a housing; a rotating sleeve provided for rotatably driving a tool and rotatably supported in said housing by at least one bearing; a driving gear-wheel installed on said rotating sleeve in a freely rotating manner and drivable by a motor; a safety clutch that couples said driving gear-wheel with said rotating sleeve in a torque-transmitting manner, wherein said safety clutch has two clutch members that are slippable, with one of said clutch members being assigned to said driving gear-wheel in a torque-transmitting manner and the other clutch member being assigned to said rotating sleeve in a torque transmitting manner, and with a coupling spring providing a force against which said clutch members can be overlatched when a limit torque is exceeded, said bearing being seated on said rotating sleeve in an axially displaceable manner and said bearing being braced against an axial stop on said rotating sleeve by said coupling spring of said safety clutch, further comprising a spring plate, said coupling spring being configured as a coil compression spring slid onto said rotating sleeve, said coil compression spring bearing against one of said clutch members with one end and against an outer diameter of one abutting surface of said spring plate at the other end; further comprising a contact shoulder on said rotating sleeve, said spring plate being located between said bearing and said contact shoulder of said rotating sleeve, wherein said bearing is configured as a roller bearing with a bearing outer ring that bears radially against said housing and a bearing inner ring seated on said rotating sleeve in a sliding manner, said bearing inner ring being loaded by said compression spring and an inner diameter of another abutting face of said spring plate against said axial stop of said rotating sleeve, and wherein said rotating sleeve has an annular groove, said axial stop of said rotating sleeve being formed by a retaining ring which is situated in said annular groove of said rotating sleeve.
