Cylindrical water turbine generator
专利汇可以提供Cylindrical water turbine generator专利检索，专利查询，专利分析的服务。并且PURPOSE:To increase ventilating characteristics and mitigate stress caused by heat elongation by a method wherein a stator is formed with an internal cylinder and an external cylinder and supported after dividing the space between both the cylinders into triangular ventilating passages in a peripheral direction. CONSTITUTION:A stator frame 6 consists of an internal cylinder 22 and an external cylinder 19 concentrically arranged in such a way that a space is provided between them in the direction of the diameter. In order to divide the space between the cylinders in a peripheral direction into a number of ventilating passages 23 with a triangular cross section, the frame is supported by a number of supports 24 extending in the direction of an axis connecting both the cylinders, the supports being inclined toward directions opposite to one after another to the axial direction. Each position located roughtly in the center between the apexes of the above triangles on the periphery of the internal cylinder 22 is provided with a key bar 25 for fixing the iron core 7 of the stator. By so doing, heat generated from the iron core 7 of the stator and the stress applied in the direction of the diameter such as what is produced by rotational force are equally distributed to the sides of the triangle.，下面是Cylindrical water turbine generator专利的具体信息内容。
