摘要： The invention relates to a method for the production of a tool receiving device (3), preferably for a drilling, chiseling or combination hammer, and for the arrangement of driving webs (9, 10) on the tool receiving device (3), comprising the following steps: - positioning at least one sleeve (8) with at least one driving web (9, 10) on an outer circumferential surface of at least one component (21) of a forming tool (20); - inserting the at least one component (21) of the forming tool (20) into a cylindrical bore (7) of the tool receiving device (3) such that an outer circumferential surface (13) of the sleeve (8) bears on an inner circumferential surface (14) of the tool receiving device (3); and - exerting a force on the outer circumferential surface of the tool receiving device (3) for forming the tool receiving device (3) and in particular for forming at least a partial region of the inner circumferential surface (14) of the tool receiving device (3), on which bears the outer circumferential surface (13) of the sleeve (8), so that a non-positive and positive locking connection is produced between the inner circumferential surface (14) of the tool receiving device (3) and the sleeve (8).

摘要： The portable power tool (1) according to the invention has a tool holder (2) for holding a tool (4) on a working axis (11), a motor (5) and a pneumatic percussion mechanism (6). A drive output shaft (7) is coupled to the tool holder (2) in order to rotate the tool about the working axis (11). A friction clutch (24) is arranged in the drive train between the motor (5) and the drive output shaft (7). The friction clutch (24) has a disc (25) on the drive-input side and a disc (26) on the drive-output side. The disc (25) on the drive-input side has, on a driving annular surface (28) bearing against the disc (26) on the drive-output side, first sectors (33) with a high coefficient of friction and second sectors (34) with a low coefficient of friction. The disc (26) on the drive-output side has, on the driven annular surface (29) bearing against the driving annular surface (28), third sectors (35) with a high coefficient of friction and fourth sectors (36) with a low coefficient of friction.

摘要： The invention relates to a production method for a tool holder comprising the following steps: A hollow spindle (main body) is formed. At least one elongated recess is provided in the wall. The spindle is composed of a first material, which comprises unalloyed or low-alloy steels. An insert is formed from a second material, a high-alloy tool steel. The insert has a base, which is complementary to the recess, and a ridge. The insert is inserted into the hollow spindle in such a way that the base lies in the recess and the ridge protrudes into an interior of the spindle. The base is soldered into the recess at a temperature lying above the Ac3 temperatures of the steels used. The combination of the hollow spindle and the insert is cooled down. A heat treatment of the combination is performed in an atmosphere containing carbon, the carbon content of which is adequate for carburizing the hollow spindle and not adequate for carburizing the insert. The heat treatment of the combination occurs at a temperature between 800 Celsius and 950 Celsius. The combination is cooled down in a salt bath or liquid bath after the heat treatment.
