Description
Technical field:
Aero-engine, gas turbine
Background technology：
Turbine outer ring attachment structure is widely used a kind of structure in aero-engine, and the structure is a kind of stator knot
Structure, the correspondence runner position outside rotor blade, during work, the gap between turbine outer ring and High Pressure Turbine Rotor blade is to whirlpool
The efficiency of wheel component has considerable influence, and small gap can bring higher efficiency, but the risk for touching mill is also bigger, therefore whirlpool
Outer shroud is taken turns in design and use, it is necessary to be reliably capable centering, otherwise rate of breakdown is higher.
Uncoordinated in order to be effective against the next thermal deformation of height temperate zone, usual turbine outer ring is both designed as the knot of circumferential sectional type
Structure, and impinging cooling hole is designed with, using the processing technology of casting.The connection of turbine outer ring and casing must pass through a centre
Casing is connected, and in order to improve turbine outer ring functional reliability, centre connection casing is typically each designed to by Foreign Engine
Thick and heavy and complicated, structural manufacturing process difficulty is big, and heavier-weight, manufacture difficulty are big.
The content of the invention：
Goal of the invention
It is contemplated that a kind of turbine outer ring mounting structure in aero-engine and gas turbine of design, by interior
Casing connects casing outside turbine with high-pressure turbine outer shroud, and inside and outside casing is reliably felt relieved by anchor ring, passes through step pin pair
Turbine outer ring is positioned, simple in construction, be convenient to mount and dismount, interchangeability and better economy, and lighter in weight.
Technical scheme
Cartridge receiver connection structure inside and outside a kind of turbine of high centering degree is provided, as shown in figure 1, the attachment structure includes turbine
The outer casing (1) of machine, step pin (2), casing (3) and turbine outer ring (4) in turbine；
Outer casing (1) the interior connection end of turbine has interior centering face, in turbine casing (3) outer connection end have it is outer fixed
Heart face, described outer turbine outer ring (4) is connected with casing in turbine (3) by hanger structure；Turbine outer casing (1), whirlpool
Casing (3) and turbine outer ring (4) are to be coaxially disposed in turbine；
Interior centering face and outer centering face are provided with pin-and-hole, and the pin-and-hole in interior centering face is adapted with axle portion on Step Shaft, outer fixed
The pin-and-hole in heart face is adapted with Step Shaft lower shaft portion.
Further, outer centering face is also formed radially in the flange stretched out, the outer casing (1) of described turbine and connected
The edge at end leans with described flange.
Technique effect：
A) it is simple in construction, easy to realize；
B) structure is convenient to mount and dismount, and interchangeability is good, and centering is reliable, is easy to the replacing to turbine outer ring.
Brief description of the drawings：
The attachment structure of Fig. 1 turbine outer rings and turbine casing
Wherein：The outer casing of 1- turbines；2- step pins；Casing in 3- turbines；4- turbine outer rings.
Embodiment：
Cartridge receiver connection structure inside and outside a kind of turbine of high centering degree is provided, as shown in figure 1, the attachment structure includes turbine
The outer casing (1) of machine, step pin (2), casing (3) and turbine outer ring (4) in turbine；
Outer casing (1) the interior connection end of turbine has interior centering face, in turbine casing (3) outer connection end have it is outer fixed
Heart face, described outer turbine outer ring (4) is connected with casing in turbine (3) by hanger structure；Turbine outer casing (1), whirlpool
Casing (3) and turbine outer ring (4) are to be coaxially disposed in turbine；
Interior centering face and outer centering face are provided with pin-and-hole, and the pin-and-hole in interior centering face is adapted with axle portion on Step Shaft, outer fixed
The pin-and-hole in heart face is adapted with Step Shaft lower shaft portion.
Further, outer centering face is also formed radially in the flange stretched out, the outer casing (1) of described turbine and connected
The edge at end leans with described flange.
2) operation principle
The casing (3) in the outer casing (1) of turbine and turbine that is mainly characterized by of this structure coordinates fixed by face of feeling relieved
The heart, is positioned by step pin (2), and the outer casing (1) of turbine and turbine outer ring (4) are connected by casing in turbine (3).Work
When, part is deformed by high temperature, and the high centering degree of casing (3) can avoid deformation in the outer casing (1) of turbine and turbine
Uncoordinated situation is measured, the positioning method using the lower tight upper pine of step pin (2) can ensure that middle level casing (3) positioning is reliable.
Claims (2)
1. a kind of cartridge receiver connection structure inside and outside turbine of high centering degree, the attachment structure includes turbine outer casing (1), step
