Claims

[Claims for Utility Model Registration] (1) A rotating shaft that has a hollow portion at the end of the shaft on the opposite load side and has a gear on the inner peripheral surface of the hollow portion, a bearing that supports this rotating shaft, and this bearing. a bracket forming a housing portion of the rotating shaft; an intermediate gear located inside the inner circumferential surface of the hollow portion of the rotating shaft and meshing with a gear provided on the inner circumferential surface of the hollow portion of the rotating shaft; a fixed shaft that is rotated at a certain position; an outer fan shaft that is located inside the inner circumferential surface of a hollow portion of the rotating shaft, has the same rotation center as the rotating shaft, and has a gear portion that meshes with the intermediate gear; An outer fan-shaped electric motor comprising: a bearing that fits into a bracket and supports the outer fan shaft; and an outer fan fixed to the outer fan shaft. (2) A rotating shaft having a hollow portion with a cylindrical inner peripheral surface at the shaft end on the opposite load side, a bearing that supports this rotating shaft, a bracket forming a housing portion of this bearing, and a hollow portion of the rotating shaft. a friction wheel located inside the inner circumferential surface of the rotary shaft and in contact with the inner circumferential surface of the hollow portion of the rotary shaft; a fixed shaft for rotating the friction wheel in a fixed position; and an inner circumference of the hollow portion of the rotary shaft. located inside the surface,
an outer fan shaft having the same rotational center as the rotational shaft and having a cylindrical portion that contacts the outer periphery of the friction wheel; a bearing that fits into the bracket and supports the outer fan shaft; and a bearing fixed to the outer fan shaft. An external fan type electric motor equipped with an external fan.
