Abstract

PURPOSE:To increase the heating surface of the turning shaft in which a heat pipe is provided by surrounding the cuter circumference of the heat pipe between a water wheel casing and a water sealing device via a ring, and forming water. passing grooves for cooling water between the ring and the heat pipe. CONSTITUTION:The turning shaft 1 of a generator is overhang-supported by a journal bearing 3 provided in a bearing stand 4, and at the end thereof a water wheel runner 5 is directly connected. Further, the water leaking from a water wheel casing 6 to the rear side of the water wheel runner 5 is sealed by a water sealing device 7. And an operating oil is filled in the hollow part between the journal bearing 3 and the water wheel runner 5 to constitute a heat pipe 2. In this constitution, between the water wheel casing 6 and the water sealing device 7, a ring 8 is provided so as to surround the turning shaft 1. And water-passing grooves 9 for circulating cooling water are formed on the turning shaft 1 between the ring 8 and the heat pipe 2.
