水流发电装置
摘要：
本发明涉及一种水流发电装置(201)，其具备：叶片(223)，其利用水流动力而旋转；转子(旋转部)(202)，其与叶片(223)连结，并与叶片(223)一体地旋转；发电机(发电单元)(206)，其与转子(202)连结，利用转子(202)的旋转力进行发电；机舱(207)，其覆盖发电机(206)，形成配置有发电机(206)的内部空间(V)与配置有叶片(223)的水中的边界，以使内部空间(V)成为气体气氛；以及轴承单元(204)，其将转子(202)支承于机舱(207)。轴承单元(204)具有：推力轴承(241)，其设置于内部空间(V)，从轴向对转子(202)进行支承；以及轴颈轴承(242)，其设置于机舱(207)与叶片(223)之间，从径向对转子(202)进行支承。
摘要（英）：

This water flow power generator 201 is provided with: a blade 223 which rotates with the force of water flow; a rotor (the rotating unit) 202 which is linked to the blade 223 and rotates integrally with the blade 223; a generator (a generator unit) 206 which is linked to the rotor 202 and generates power with the rotational force of the rotor 202; an internal space V which covers the generator 206and in which the generator 206 is arranged; a nacelle 207 which forms a boundary with the water where the blade 223 is arranged and has an internal space V that is a gas environment; and a bearing unit 204 which supports the rotor 202 with respect to the nacelle 207. The bearing unit 204 comprises a thrust bearing 241 which is provided in the internal space V and which supports the rotor 202 fromthe axial direction, and a journal bearing 242 which is provided between the nacelle 207 and the blade 223 and which supports the rotor 202 from the radial direction.
