Definitions

  • the present invention relates to a handheld power tool and a manufacturing method for a handheld power tool.
  • Hand-held power tools such as rotary hammers, usually have a motor for driving a gear or a drive unit.
  • the transmission or the drive unit comprise, for example, a drive shaft and/or an impact mechanism.
  • the motor serves to drive a drive shaft in rotation about a working axis in order to turn a tool of the hand-held power tool, such as a drill, along the working axis into a substrate by means of a rotary movement of a tool holder coupled to the drive shaft.
  • the motor is accommodated, for example, in a separate motor housing to which a gear housing is attached (eg via an end shield). It is known to attach a transmission housing to a bearing plate and a motor housing by means of four screws which are each passed through bores in the transmission housing and the bearing plate and are screwed into the motor housing. For this purpose, sufficient space for corresponding counter parts of the screws is required in the motor housing for fastening the screws.
  • the four screws are screwed into screw domes of the motor housing, which are arranged around the motor in the motor housing. Due to the arrangement of the four screw domes, the known motor housing has a relatively large outer circumference and is difficult for a user to hold in his hand.
  • the object of the present invention is to provide an improved handheld power tool and an improved manufacturing method for a handheld power tool.
  • a hand-held power tool which includes a gear housing for accommodating a gear and a motor housing for accommodating a motor.
  • the hand-held power tool includes an end shield, which is arranged between the transmission housing and the motor housing, for supporting a shaft of the motor.
  • the hand-held power tool comprises at least one first screw, which fastens the bearing plate to the motor housing, with the first screw being disengaged from the gear housing, and at least one second screw, which fastens the gear housing to the bearing plate, the second screw being disengaged from the motor housing stands.
  • the at least one second screw which fastens the transmission housing to the bearing plate, is not in engagement with the motor housing, no space is required in the motor housing for arranging a counterpart for the at least one second screw. For example, no space is required in the motor housing for arranging one or more screw bosses into which the at least one second screw can be screwed.
  • the motor housing can thus be made slimmer and can be held and guided better by a user.
  • the hand tool is, for example, a hammer drill or a chisel hammer.
  • the motor is used, for example, to drive a drive shaft of the transmission (drive unit) in rotation and/or to drive an impact mechanism in a percussive manner.
  • the drive shaft is coupled to a tool holder of the hand-held power tool, for example, so that a tool held in the tool holder, for example a drill, can be rotated about a working axis.
  • the tool can be hammered into a substrate by means of the impact mechanism in addition to rotating about the working axis in an impact direction along the working axis.
  • the gear housing is made of metal, for example.
  • the transmission of the hand-held power tool is accommodated in the transmission housing.
  • the transmission of the handheld power tool is a drive unit of the handheld power tool, which includes a drive shaft, a percussion mechanism and other drive components such as an eccentric, a connecting rod and gears.
  • a tool holder, for example, is fastened to the transmission housing.
  • the transmission housing can be accommodated, for example, in a plastic housing (plastic casing) in order to prevent the user from touching metal parts of the hand-held power tool for reasons of electrical safety.
