Description
Technical Field
[0001] This utility model relates to the technical field of turbine support ring and fuel injection ring disassembly device, specifically a turbine support ring and fuel injection ring disassembly device. Background Technology
[0002] The turbine support ring is a key component of a turbocharger, primarily used to support the turbocharger's rotor and ensure its stable high-speed rotation. Turbochargers increase the intake air volume by compressing air, thereby increasing engine output power. The moving parts of a turbocharger include the turbine impeller, compressor impeller, and rotor shaft. These components require special bearings for support during high-speed operation. Turbocharger bearings are mainly divided into two categories: floating bearings and ball bearings. Floating bearings are a special type of floating bearing, typically composed of copper rings. There is a gap between the rings, the shaft, and the bearing housing, forming a double-layer oil film. The rotor floats on this oil film and rotates at high speed. This type of bearing is simple in structure, durable, and cost-effective, and is widely used in products from major automobile manufacturers. Ball bearings, on the other hand, install balls on the turbine shaft, replacing the oil in floating bearings. They are suitable for high-performance vehicles and offer higher precision and efficiency. The turbine support ring connects the first-stage and third-stage turbine guides. The outer ring of the turbine support ring, which mates with the oil injection ring in its lubrication chamber, and the inner ring of the bearing on the low-pressure turbine rotor are designed to mate after assembly. After the turbine support ring is assembled, the axial runout of the outer ring and the inner ring of the bearing on the low-pressure turbine rotor must be within acceptable limits to ensure the normal operation of the gas turbine.
[0003] In the maintenance and repair of turbine engines, the removal of the turbine support ring and fuel injection ring is a complex and critical task. Because the fuel injection ring is typically installed inside the turbine support ring in a concealed and tightly fitted location, traditional removal methods often have several problems, such as the risk of damaging the fuel injection ring or turbine support ring during removal, low removal efficiency, and the need for significant time and manpower.
[0004] Therefore, this utility model provides a turbine support ring and fuel injection ring disassembly device to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model provides a turbine support ring and fuel injection ring disassembly device, such as... Figure 1-5 As shown, the turbine support ring and fuel injection ring disassembly device includes a gland 100, a plurality of pins 101, a plurality of countersunk screws 103, an adapter plate 104, a plurality of pads 105, a plurality of stops 106, a plurality of socket head cap screws 107, a screw rod 108 and a lever 109, with the lever 109 located at the right end of the screw rod 108.
[0024] The pressure cap 100 is located at the left end of the screw 108, and the pin 101 is used to fix the pressure cap 100 to the screw 108.
[0025] The adapter plate 104 is located on the screw 108 at one end near the pressure cap 100.
[0026] The spacers 105 are evenly distributed on one side surface of the adapter plate 104, and the countersunk screws 103 are used to fix the spacers 105 to the adapter plate 104.
[0027] The stop blocks 106 are evenly distributed on one side surface of the adapter plate 104 and correspond one-to-one with the pad blocks 105. The hex bolts 107 are used to fix the stop blocks 106 to the adapter plate 104.
[0028] In summary: First, the operator installs the lever 109 onto the right end of the screw 108. Next, the adapter plate 104 is installed onto the screw 108. Then, the left end of the screw 108 is installed onto the pressure cap 100 and secured with the pin 101. Then, the pad 105 and the stop block 106 are installed onto the adapter plate 104 in sequence. Finally, the countersunk screw 103 and the socket head cap bolt 107 are tightened to secure them. The operator then removes the oil injection ring on the turbine support ring by rotating the lever 109. During removal, the pressure cap 100 on the turbine support ring oil injection ring removal device is first placed at the bottom of the turbine support ring lubricating oil cavity. When placing it, care must be taken to avoid contact with the oil injection ring. The nozzles are staggered. After placement, the turbine support ring injection ring disassembly device is rotated until the adapter plate 104 coincides with the injection ring nozzle position. After rotating to a certain position, the stop block 106 of the turbine support ring injection ring disassembly device will be positioned with the turbine support ring injection ring nozzle. At this time, the turbine support ring injection ring can be removed from the lubrication chamber by rotating the lever 109, which meets the needs of the workers and avoids damage to the turbine support ring lubrication chamber and assembly parts during disassembly. There is no need to align the axial parallelism, as the disassembly device can ensure it, reducing labor, making operation convenient and quick, ensuring the safety of assembly and disassembly of parts, improving work efficiency, and making it highly practical.
