The mounting portion between the insulator 9 and the flange 10 is configured to have a tapered portion with a large diameter on the inside of the machine, and a ring-shaped tightening nut 12 surrounding the insulator 9 is screwed into the flange 10 from the inside of the machine, and the insulator 9 is pressed against the flange 10 and fixed. are doing. Here, a spacer 11 is provided between the tightening nut 12 and the insulator 9.
This prevents the insulator 9 from being damaged by the tightening nut 12 when it is inserted and tightened. Furthermore, the flange 10 is attached to the terminal box 4 with bolts 8, and a gas seal 13 is inserted between the flange 10 and the terminal box 4 to provide a gas seal. Further, the flange 10 has a plurality of seal grooves 14 in the circumferential direction in the tapered portion and the seal grooves 1
4, and a sealing material pressurizing port 16 and an air vent port 17 connected to the vertical grooves 15. Furthermore, a take-out valve 18 is attached to a location where the pipes connected to these holes 16 and 17 can be easily operated. The sealing material is injected through one valve 18a, and the sealing material is press-fitted into the tapered portion while removing air from the other valve 18b.In order to strengthen the prevention of leakage of the sealing material on the tapered surface, the sealing material is injected into the tapered portion. Place O-rings 19 such as chloroprene rubber on both sides.
It is placed in the ring groove 21.

子９に傷がつかない。 The operation of the dispensing device configured as described above will be explained next. First, by attaching the insulator 9 to the flange 10 with its tapered part, the insulator 9 can receive its own weight and the internal pressure of the machine.Further, the insulator 9 is pressed and fixed against the flange 10 using the tightening nut 12 to form an integral unit. Can be reversed during assembly and perform leak tests on a single unit. Moreover, it can sufficiently withstand the torque load applied to the insulator 9 by the tightening nut 12. Also tightening nut 12
Since the insulator 9 is tightened through the spacer 11, the insulator 9 and the tightening nut 12 do not come into direct contact, and the insulator 9 is not damaged.

たとえばシリコーングリースが用いられる。 The seal material injected from one valve 18a passes through the pressure inlet 16 and the vertical groove 15, and then passes through the seal groove 1.
4 and between the tapered portion between the seal groove 14 and the O-ring 19, cooling gas can be sealed. This sealing material is preferably one that has high viscosity and does not solidify even after being filled, and further preferably one that solidifies if it leaks from the sealing groove 14 and O-ring 19 and comes into contact with air or the like.
For example, silicone grease is used.

恐れもなくなる。 As described above, according to this embodiment, by sealing between the tapered portion and flange 10 and the terminal box 4, there is no need to insert the packing 7 between the insulator 9 and the terminal box 4 as shown in FIG. There is no need to adjust the tightness of the packing. In addition, there is no concentrated load on the insulator due to misalignment of cementing, etc., and there is no fear of cracking of the flange 10.

As described above, according to the present invention, in the outlet device for a gas-cooled rotating electric machine, a tapered part is provided in the conventional cementing part and the sealing material is filled, so that it is more reliable in terms of strength and handling. Now I can improve my sexuality. In particular, the advantage of moving the seal to the flange instead of the insulator allows for a sufficient gas seal is significant. Furthermore, if the seal at the tapered portion becomes incomplete, it is now possible to easily press-fit a sealing material from outside the machine during operation, which is of great benefit in terms of maintenance and inspection.
