Abstract
A bearing casing is characterized in that an external ring is V-shaped and an internal ring is C-shaped, and the external ring is connected with the internal ring.
Description
Technical field
The utility model relates to the gas turbine turbine technology.
Background technique
Gas turbine turbine exhaust diffuser basic structure is made of exhaust casing, support plate, bearing casing and supporting casing.Because temperature must be higher than cylinder place temperature in the blast tube, the thermal expansion amount of support plate is big, and the swell increment of cylinder is little, and along with constantly changing repeatedly of operating temperature, outside cylinder and support plate crack initiating failure because of thermal fatigue in causing easily.The hot problem of disharmony that solves cylinder and support plate generally has two kinds of structural designs, and a kind of is that supporting casing framework adds tapered wall, and another kind is that supporting casing framework adds oblique support plate, but these two kinds of structures more complicated all is not easy to realization.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, supporting casing of being easy to realize.
The utility model provides a kind of supporting casing, it is characterized in that: outer ring portion is the V-arrangement shape, and annular inner portion is the C shape, and VC links to each other, and forms elastic member.When the thermal expansion amount of support plate is big, utilize the resiliently deformable of yielding support casing to absorb the thermal expansion amount of support plate, reduce the extruding of support plate, thereby keep this part thermostability of turbine exhaust casing cylinder, avoid support plate and cylinder to produce heat fatigue cracking.
The supporting casing that the utility model provides, its outer ring portion two places are connected with the cylinder support plate with screw bolt and nut, and annular inner portion is connected with the bearing casing with tight bolt, to keep the balance on the fore-and-aft direction.
The supporting casing that the utility model provides, its advantage is: absorbs the thermal expansion amount of support plate, reduces the extruding of support plate, keep this part thermostability of turbine exhaust casing cylinder, simple in structure, be easy to processing and assembling.
Description of drawings
Fig. 1 is the structural representation of supporting casing.
Embodiment
Embodiment 1
The structure of supporting casing as shown in Figure 1, its outer ring portion is the V-arrangement shape, annular inner portion is the C shape, VC links to each other, and forms elastic member; Outer ring portion two places are connected with the cylinder support plate with screw bolt and nut, and annular inner portion is connected with the bearing casing with tight bolt.During work, the support plate expanded by heating, because of cylinder is a rigid design, and the supporting casing is an elastic design, yielding support casing pressurized absorbs the thermal expansion distortion of support plate to internal strain, thereby guarantees that cylinder is not subjected to too big thermal pressure, avoids the thermal fatigue of support plate, cylinder.
