Description

Technical Field

[0001] This utility model relates to the field of turbine assembly technology, specifically to a turbine component retaining ring assembly fixture. Background Technology

[0002] The turbine assembly is one of the core components of an aircraft engine. It is responsible for converting the energy of the high-temperature, high-pressure combustion gases generated in the combustion chamber into mechanical energy to drive the compressor and fan, and to provide thrust for the aircraft. The turbine assembly operates in an extremely harsh environment (high temperature, high pressure, high speed), and its assembly precision directly affects the engine's performance, efficiency, and lifespan.

[0003] The snap ring in the turbine assembly is a key fastener. It is installed in the annular groove of the turbine disk, shaft or other components. Through the radial tension generated by elastic deformation, it fixes adjacent components (such as bearings, sealing rings, blade tenons, etc.) in the designed position and prevents axial movement, thereby ensuring the stability and reliability of the turbine assembly under high speed, high temperature and high load.

[0004] In the prior art, when assembling snap rings, snap ring pliers are usually used to install the snap rings in the grooves, which often has the following disadvantages: (1) The intervention of snap ring pliers may interfere with or wear the components around the grooves; (2) In order to improve turbine performance, the grooves for snap ring installation are becoming narrower and narrower during the design, and it is difficult for existing snap ring pliers to fix the snap rings before installation; (3) During installation, the snap rings may deform due to uneven force, or affect the assembly effect.

[0034] In this embodiment, there are multiple jacking components 2; the multiple jacking components 2 are arranged in an array and installed on the main support 1; each jacking component 2 is screwed onto the main support 1.

[0035] In this embodiment, the jacking assembly 2 includes a cantilever 201, a first adjuster 202, and a pad 203; one end of the cantilever 201 is installed on the side of the main support 1 away from component one; the pad 203 is installed on the other end of the cantilever 201 through the first adjuster 202, and the pad 203 is located on the side of the cantilever 201 closer to component one; the pad 203 is used to support component two; the first adjuster 202 is used to adjust the relative distance between the pad 203 and the cantilever 201.

[0036] Furthermore, such as Figure 4 As shown, the cantilever 201 is installed in the radial direction. One end of the cantilever 201 is detachably mounted on the main bracket 1 by two hexagon socket screws, and the other end of the cantilever 201 extends from the outer edge of the annular main bracket 1. The pad 203 is an arc-shaped pad that fits the shape of the second component and can provide a uniform force to the second component. The first adjuster 202 is a hexagon socket screw that passes through the cantilever 201.

[0037] In this embodiment, there are multiple claw assemblies 3, which are arranged in an array on the main support 1; each jacking assembly 2 is movably mounted on the main support 1 by screw connection. There are 12 jacking assemblies 2 and 12 claw assemblies 3; the jacking assemblies 2 and claw assemblies 3 are arranged alternately on the main support 1 at equal intervals.

[0038] In this embodiment, the claw assembly 3 includes a fixing block 301, a second adjuster 302, a claw 303, and a pressure bar 304; the fixing block 301 is installed on the side of the main support 1 away from the first component; the claw 303 is installed on the side of the main support 1 close to the first component; the claw 303 is connected to the fixing block 301 through the second adjuster 302, and the claw 303 can slide radially along the main support 1; the pressure bar 304 is disposed at one end of the claw 303 near the groove, and the pressure bar 304 is used to press and limit the retaining spring within the groove.

[0039] In this embodiment, the main bracket 1 has an installation groove 101 on the side near component one; the claw 303 is disposed in the installation groove 101; the end face of the claw 303 near component one is flush with the end face of the main bracket 1 near component one.

By turning the second adjuster 302, the pressure strip 304 at the end of the retaining claw 303 presses down on the retaining spring 7. A total of 12 retaining claw assemblies 3 press and limit the retaining spring 7 in the groove 6. At this time, the retaining spring 7 is evenly stressed and undamaged.

[0043] Align component 25 with component 14 axially, and screw on the first adjuster 202 to gradually push component 25 with the pad 203, so that the inner edge of component 25 presses against the outer side of the retaining ring 7 and the pressure strip 304. When all 12 jacking components 2 are adjusted into place, the turbine assembly is in place. Keep the pad 203 in place and remove the pressure strip 304 so that the inner edge of component 25 is pressed against the retaining ring 7. Then remove this tooling.
