Patent ID: 7854649

Claim:
A hand-held power tool, in particular a sander, comprising a housing ( 10 ) and a motor ( 12 ), which is located in the housing ( 10 ) and by which a driven shaft ( 16 ), extending from a face end ( 14 ) of the housing ( 10 ), is drivable, the driven shaft ( 16 ) extending in a longitudinal direction, and further comprising a suction conduit ( 18 ), extending at least partway through the housing ( 10 ), wherein the suction conduit ( 18 ) extends in the longitudinal direction of the driven shaft ( 16 ) past a bearing flange ( 32 ) of the driven shaft ( 16 ) to an outside of the housing ( 10 ), wherein the bearing flange ( 32 ) extends 360° around the driven shaft ( 16 ) in a plane perpendicular to the longitudinal direction of the driven shaft ( 16 ), wherein the bearing flange is defined by a radial distance R bf extending from an outer edge of the driven shaft ( 16 ) to an outer edge of the bearing flange ( 32 ), wherein the suction conduit ( 18 ) operates as an intake, shaped as an annular gap on the face end ( 14 ) of the housing ( 10 ) between the bearing flange ( 32 ) of the driven shaft ( 16 ) and the housing ( 10 ) in the plane perpendicular to the longitudinal direction of the driven shaft ( 16 ), wherein the angular gap is formed by a radial distance R g between an outer edge of the bearing flange ( 32 ) facing the housing ( 10 ) in the plane perpendicular to the longitudinal direction of the driven shaft ( 16 ) and an inner edge of the housing ( 10 ) facing the bearing flange ( 32 ) and extending perpendicular to the face end ( 14 ) of the housing ( 10 ), wherein the radial distance R g is measured in the plane perpendicular to the longitudinal direction of the driven shaft ( 16 ), wherein the annular gap includes a radial extent that is defined by the radial distance R g , wherein the driven shaft ( 16 ) is defined by a radius R s extending from an axial center of the driven shaft ( 16 ) to an outer edge of the driven shaft ( 16 ) and wherein the radial extent of the annular gap is smaller than a diameter of the driven shaft ( 16 ) that is equal to two times the radius R s .
