The hand-held power tool () includes a transmission housing () for receiving a transmission (), a motor housing () for receiving a motor (), a bearing plate () arranged between the transmission housing () and the motor housing () for mounting a shaft () of the motor (), at least one first screw () which fastens the bearing plate () to the motor housing (), wherein the first screw () is not in engagement with the transmission housing (), and at least one second screw () which fastens the transmission housing () to the bearing plate (), wherein the second screw () is not in engagement with the motor housing ().

Hand-held power tool and production method for a hand-held power tool

A receiving apparatus for an electronic device is provided, in particular of a machine tool, including a receiving device for receiving the electronic device and a fastening device for connecting the receiving device to a housing of the machine tool. A displacement device is provided which is connected to a displacement mechanism of the receiving device such that the receiving device is displaceable relative to the displacement device, a blocking device being provided which interacts with the displacement mechanism and is coupled to the displacement device, the displacement device being connectable to the housing of the machine tool by the fastening device, and it being possible to secure the blocking device to the displacement mechanism of the fastening device when the fastening device is connected to the housing of the machine tool, and thus a displacement of the displacement device relative to the displacement mechanism can be prevented. The invention also relates to an assembly consisting of a receiving apparatus and a housing.

Receiving apparatus for an electronic device and assembly

A fan having an air guide and a flywheel is provided, the flywheel being attached to a shaft, for cooling an electric motor. The electric motor has a rotor which can be attached to the shaft. The air guide is arranged in an interchangeable manner at a position between the flywheel and the rotor with respect to the axial direction, and has an air guide opening with an inner cross section for the purpose of forming a blowing channel. An air flow generated by the flywheel can be guided through the blowing channel in the axial direction. The inner cross section is smaller than an outer cross section of the rotor.
