Electric hand-held power tool

The invention relates to an electric hand-held power tool (1), in particular an angle grinder (2), comprising a housing (3) in which an electric motor (6) is accommodated, which drives a rotor shaft (11), which is connected in a force-transmitting manner to an output unit (13) accommodated in a transmission head (12). According to the invention, a housing ring (16) is provided, which provides at least one guide section (27) for the transmission head (12) and a guide (30) for the electric motor (6). An air guide section (24) is formed on the side of the housing ring (16) facing away from the housing (3), in which air guide section a ventilation device (25) fastened to the rotor shaft (11) is accommodated. 本发明涉及一种电的手持式工具机（1）、尤其角磨机（2），其具有壳体（3），在该壳体中容纳有电动马达（6），所述电动马达驱动转子轴（11），所述转子轴与容纳在传动机构头部（12）中的输出单元（13）以力传递的方式连接。设置了壳体环（16），该壳体环提供了用于所述传动机构头部（12）的至少一个导引区段（27）和用于所述电动马达（6）的导引部（30）。在所述壳体环（16）的远离壳体（3）指向的侧部处构造有空气引导区段（24），在所述空气引导区段中容纳有紧固在所述转子轴（11）上的通风设备（25）。
