【考案の詳細な説明】
この考案は回転軸上に取付けられる固定部と回
転部とからなる回転機における固定部固定装置に
関するものである。DETAILED DESCRIPTION OF THE INVENTION This invention relates to a fixed part fixing device for a rotating machine that includes a fixed part mounted on a rotating shaft and a rotating part.
この種の装置として、第１図乃至第４図に示す
オーバーハングPGがある。図において、１は回

である。 As this type of device, there is an overhang PG shown in FIGS. 1 to 4. In the figure, 1 is the rotating machine main body, 2 is the rotating shaft, 3 is the sliding bearing for the rotating machine main body, 4 is the fixed part, 5 is the rotor, 6 is the bearing, 7 is the rotation stopper rod, 8 is the stroke bearing, 9
is a housing that houses the stroke bearing 8.

持であるので、回転による振動に対しても問題な
く運転できる。 In such a device, when the rotating shaft 2 rotates, the fixed part 4 tries to rotate, but the rotation is stopped by the rotation stopper rod 7. Furthermore, since the bearing 3 of the rotating machine main body 1 is a sliding bearing and has end play E, the rotating shaft 2 moves in the axial direction due to misalignment of the magnetic center or mechanical thrust. Therefore, the fixed part 4 and the rotating part 5 can be operated without changing their relative positions. Further, since the fixed part 4 is supported at both ends by the two bearings 6, it can be operated without any problems due to vibrations due to rotation.
ところで、オーバーハングPGのように、内部

置調整などが難かしくなり、機器全体の構造も複
雑になるなどの欠点があつた。 By the way, for devices such as overhang PGs that are relatively easy to internally inspect and assemble, there is no problem with the conventional fixed part fixing method, but for thyristor motor distributors that have several rotation detectors built into the fixed part. In such cases, a structure with two fixed part support bearings on both sides like the PG has disadvantages such as making assembly, disassembly, and adjusting the position of the detector difficult, and making the overall structure of the device complicated. .
この考案は上記のような従来のものの欠点を除
去するためになされたもので、固定部支持軸受を
１個にして、組立て、分解、調整が容易にできる
ようにし、また軸受を１個にすることにより生じ

装置を提供することを目的としている。 This idea was made in order to eliminate the drawbacks of the conventional ones as described above, and it made it possible to easily assemble, disassemble, and adjust by using only one fixed part support bearing, and it also reduced the number of bearings to one. It is an object of the present invention to provide a fixing device that can eliminate the vibration of the fixing part during rotation caused by this by attaching a spring to the rotation preventing rod part.

回り止めロツド７との間に取付けられる。 An embodiment of this invention will be described below regarding a distributor for a thyristor motor. 5 to 7, 2 is a rotating shaft, 4 is a fixed part, 6 is a bearing, 7 is a rotation stopper rod, 10 is a rotation detector, and the rotating shaft 2
3 to 6 pieces can be installed surrounding each other. 11 is a mounting seat for the rotation detector 10, 12 is a rotating disk, 13
1 is a mounting boss of the rotary disk 12, 14 is a stator cover, and 15 is a spring. The mounting portion of the rotation stopper rod 7 is the same as that shown in FIG. 4 of the conventional device, and the spring 15 is installed between the housing 9 and the rotation stopper rod 7.

取付けることにより解消される。 Next, its operation will be explained. When the rotating shaft 2 rotates, the fixed part 4 tends to rotate, but the rotation of the fixed part 4 is stopped by the rotation stopper rod 7. With respect to the free movement of the rotating shaft 2, the stroke bearing 8 allows operation without changing the gap between the rotation detector 10 attached to the fixed part 4 and the rotating disk 12. In addition, since only one fixed part support bearing 6 is provided, the installation and structure of the fixed part cover 14 are simplified, and attachment and detachment are easy.
Adjustment, inspection, and installation of the rotation detector 10 become easy. When only one fixed part support bearing 6 is used, when the rotating shaft 2 rotates, the outer periphery of the fixed part 4 vibrates in the axial direction around the bearing 6. This can be solved by installing a spring 15 between the rotary shaft 2 and the fixed part vibration force, which is adapted to the axial force generated when the rotary shaft 2 moves freely, and the vibration force of the fixed part.

きる。 As described above, according to this invention, since the number of stator supporting bearings is reduced to one, assembly, disassembly, inspection, and adjustment of the interior of the fixed portion can be easily performed, and the device can also be made inexpensive. Furthermore, by providing a spring in the stroke bearing part, vibrations in the fixed part can also be reduced.
