PURPOSE:To suppress the temperature rise of lubricating oil by disposing a coiled pipe oppositely to a load side bracket, and connecting the interior of a chamber between a diaphragm and the hole of a thrust case with the periphery of a rotor. CONSTITUTION:A connecting hole 21 formed at an upper bracket 6 is connected with a connecting slot 10. A connecting hole 22 formed at the hole side of a thrust case 15 is connected with the interior of a room 23 formed between a diaphragm 19 and a wall 16. One end side of a pipe 24 disposed at the top of a top bracket 6 and formed in a coil shape is connected with the hole 21 and connected with the hole 22 at the other end side. Since a pipe 24 is disposed and exposed with the top of the bracket 6, the pipe 24 is cooled with water in the periphery, sealing liquid returned to a motor via the hole 22 is circulated from the room 23 through a connecting hole 17 into the case 15, through a connecting slot 11, around a rotor 11, further a connecting slot 10 and the hole 21, and cooled again by the pipe 24. |
