Title:
CYLINDRICAL WATER-WHEEL ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPS5815456
Kind Code:
A
Abstract:
PURPOSE:To prevent the deformation of a stator frame by providing a mechanism for supplying grease to the slide surface of a support for holding the frame in a water channel and providing a packing at the end of the slide surface, thereby smoothly sliding the slide surface. CONSTITUTION:When the stator frame of a cylindrical water-wheel rotary electric machine is held by a support 15 via a slide surface 14 in a water channel, a grease reservoir 16 for supplying grease to the slide surface 14 is formed through the slide surface 14. Further, a grease filling hole 17 is formed to communicate with the reservoir 16, and a packing 18 is disposed at the end of the slide surface 14, thereby preventing the grease from flowing away. In this manner, the sliding of the slide surface 1 can become smooth, thereby improving the supporting of the frame and preventing the deformation of the frame.
