Hand-held power tool

Abstract

The invention relates to a hand-held power tool having a drive motor and a striking mechanism for the rotating or impact drive of a tool, which is accommodated in a tool holder. A transmission gearing and a torque clutch are disposed in the transmission path between the drive motor and the tool holder in order to limit the transferable torque. A threshold torque can be set in the torque clutch.

         14 . A hand-held power tool that is usable as a rotary hammer and as a drill, comprising:
 a drive motor:   an impact mechanism for driving a tool of the hand-held power tool in a rotating and/or hammering mode;   a tool holder accommodating the tool; and   a reduction gear and a torque clutch which limit the transmissible torque being situated in a transmission path between the drive motor and tool holder, wherein a torque limitation in the torque clutch can be set.   
     
     
         15 . The hand-held power tool as recited in  claim 14 , wherein the drive motor, the reduction gear, the impact mechanism, and the torque clutch are situated one after another and flush with one another in a line. 
     
     
         16 . The hand-held power tool as recited in  claim 14 , wherein the torque clutch is situated between the impact mechanism and the tool holder. 
     
     
         17 . The hand-held power tool as recited in  claim 15 , wherein the torque clutch is situated between the impact mechanism and the tool holder. 
     
     
         18 . The hand-held power tool as recited in  claim 14 , wherein the impact mechanism is situated between the torque clutch and the tool holder. 
     
     
         17 . The hand-held power tool as recited in  claim 15 , wherein the impact mechanism is situated between the torque clutch and the tool holder. 
     
     
         20 . The hand-held power tool as recited in  claim 16 , wherein the reduction gear is situated immediately at the output side of the drive motor. 
     
     
         21 . The hand-held power tool as recited in  claim 18 , wherein the reduction gear is situated immediately at the output side of the drive motor. 
     
     
         22 . The hand-held power tool as recited in  claim 20 , wherein the reduction gear is a planetary gear. 
     
     
         23 . The hand-held power tool as recited in  claim 21 , wherein the reduction gear is a planetary gear. 
     
     
         24 . The hand-held power tool as recited in  claim 14 , wherein the hand-held power tool is equipped with a battery pack which supplies current to the electric drive motor. 
     
     
         25 . The hand-held power tool as recited in  claim 15 , wherein the hand-held power tool is equipped with a battery pack which supplies current to the electric drive motor. 
     
     
         26 . The hand-held power tool as recited in  claim 14 , wherein the impact mechanism is mechanically actuated. 
     
     
         27 . The hand-held power tool as recited in  claim 15 , wherein the impact mechanism is mechanically actuated. 
     
     
         28 . The hand-held power tool as recited in  claim 14 , wherein the impact mechanism is pneumatically actuated. 
     
     
         29 . The hand-held power tool as recited in  claim 15 , wherein the impact mechanism is pneumatically actuated. 
     
     
         30 . The hand-held power tool as recited in  claim 14 , wherein it is possible to set at least two torque stages in the torque clutch when it is in an operative position. 
     
     
         31 . The hand-held power tool as recited in  claim 14 , wherein the tool holder is embodied in the form of a drill chuck. 
     
     
         32 . The hand-held power tool as recited in  claim 14 , wherein the tool holder is embodied in the form of a slit clamping sleeve. 
     
     
         33 . The hand-held power tool as recited in  claim 14 , wherein it is possible to switch the torque clutch between an operative position and an inoperative position in which the torque limitation is deactivated in the inoperative position.
