Description

[Detailed Description of the Invention] This invention relates to a stator mounting device for a rotating machine, and is designed to allow stator cores of different lengths to be mounted on a single platform.

BACKGROUND ART Some rotating machines such as electric motors and generators have stators and rotors of different lengths even if their outer diameters are the same, depending on their capacity.

Conventionally, in such cases, it has been common practice to manufacture and use mounting members for each model to support the stator core on the base.

However, this requires the preparation of a wide variety of mounting members, and it has been desired that some kind of solution be found in terms of manufacturability and economy.

The purpose of this invention is to provide a stator mounting device that can be applied to rotating machines with different stator core lengths.

According to the present invention, in a rotating machine in which a stator core is attached to a base via a pair of ventilation partition plates that support mounting legs at both ends of the stator core and partition a ventilation path of the stator core, the ventilation partition The cross section of the plate in the axial direction is formed into a double-shape, and the upper end face of the ventilation partition plate is fixed to the mounting legs at both ends of the stator core with bolts, and the lower end face of the ventilation partition plate is fixed to the base plate with bolts. This is achieved by fixing the ventilation partition plates to stator cores having different axial lengths by changing the opposing mounting directions of the ventilation partition plates.

To explain one embodiment of this invention with reference to the diagram, first
In the figure, reference numeral 1 denotes a stator core, and a stator winding 2 is wound around a groove in the inner circumference of the stator core.

At the bottom of the mounting legs 3.4 provided at both ends of the stator core 1, a pair of ventilation partition plates 5, 6, which are mounting members having a double-shaped cross section in the axial direction, are provided. The upper end surfaces of the ventilation partition plates 5 and 6 are fixed to the mounting legs 3.4 at both ends of the stator core with bolts, and the ventilation partition plates 5 and 6 are
, 6 are fixed to the platform 7 with bolts.

If you look at the ventilation partition plates 5 and 6 in the radial direction of the shaft, you can see that the upper part supports a circular stator with mounting legs 3 and 4 in a semicircular shape, and the lower surface is in contact with the horizontal platform 7. It is formed into a plate shape.

Therefore, the ventilation partition plates 5 and 6 support the stator core 1 and prevent the wind passing through the stator core 1 from leaking to the outside from between the stator and the platform 7 at both ends of the stator. be able to.

In this way, the ventilation partition plates 5 and 6 not only support the stator core 1, but also function as a partition to prevent the air passing through the stator core from leaking outside, and have the advantage of enhancing its cooling effect.

According to this invention, a pair of ventilation partition plates 5゜6 are formed with a Z-shaped cross section in the axial direction, and the upper end surfaces of the ventilation partition plates 5゜6 are fixed to the mounting legs at both ends of the stator core with bolts. At the same time, by fixing the lower end faces of the ventilation partition plates 5, 6 to the base with bolts, simply change the orientation of the opposing partition plates 5, 6 and attach them to the mounting legs at both ends of the stator core and the base. This makes it possible to use common parts to support and fix stator cores of the same series with different lamination thicknesses.

That is, when the two-character shaped ventilation partition plates 5 and 6 are used, in the case of the stator core 1 having the length a shown in FIG.
6 are attached so that the ends on the platform 7 side face each other, but if the orientation of the ventilation partition plates 5 and 6 is changed and the ends on the platform side face outward, As shown in FIG. 2, stator cores 1' having different lengths a' can be easily mounted on the same platform 7.

As mentioned above, this idea is a mounting member for the stator core.
The pair of ventilation partition plates has a double-shaped cross section in the axial direction, and is configured so that the opposing mounting directions can be changed. There is an advantage that it can be attached using a common member.

Further, even when a short stator core is installed, since all other members are common, there is an advantage that the ventilation cross-sectional area around the core is not narrowed.
