description	The utility model discloses a cooling tower fan, including fan aircraft nose and blade, the petiole terminal surface and the fan aircraft nose terminal surface of blade are connected through a plurality of connecting bolt, a plurality of connecting bolt evenly arrange along petiole terminal surface circumference, the composition surface of petiole and fan aircraft nose is intermeshing's terminal surface tooth. The utility model discloses a terminal surface tooth structural connection, stress is partly during fan operation is born by connecting bolt, and partly terminal surface tooth by the meshing bears, and distributing of stress has evenly avoided stress concentration's phenomenon, and the location rigidity is good, and bearing capacity is big. 本实用新型公开了种冷却塔风机，包括风机机头和叶片，所述叶片的叶柄端面与风机机头端面通过多个连接螺栓连接，所述多个连接螺栓沿叶柄端面周向均匀布置，所述叶柄与风机机头的接合面为相互啮合的端面齿。本实用新型采用端面齿结构连接，风机运行时应力部分由连接螺栓承受，部分由啮合的端面齿承受，应力分布均匀避免了应力集中的现象，定位刚性好，承载能力大。
