Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of aero-engine transmission system, especially relates to a nozzle with replaceable spray hole structure. BACKGROUND

[0002] Spray cooling lubrication is widely used in the field of high-speed gear transmission such as aero-engine accessory drive. The oil is sprayed to the target position through the spray hole to achieve cooling and lubrication. When designing the product, the heat generated by the lubrication target structure and the oil demand can be met by controlling the nozzle structure. However, the spray amount, scattering degree, target position and other effects obtained by complex calculation simulation such as theoretical formula and CFD (Computational Fluid Dynamics) simulation analysis often deviate from the actual test target effect.

[0003] In mature structures, the fewer and simpler the parts are, the more reliable the structure is considered to be. Therefore, the product configuration often uses an integrated nozzle, that is, multiple spray holes are integrated on the same nozzle to meet the lubrication needs of multiple targets.

[0004] However, the integrated nozzle structure has high machining difficulty and cannot be changed after the physical finished part is machined. Once the original nozzle structure does not work well, the original design scheme needs to be changed and a new integrated nozzle needs to be machined, which will lead to long machining time, increased test cost and reduced design and development efficiency.

[0005] Therefore, in the two cases of product target and test scene and research and development process, the variability and flexibility of the nozzle structure exist certain contradictions. On the one hand, in order to meet the lubrication needs of multiple targets, an integrated nozzle is used; on the other hand, the inherent characteristics of the integrated nozzle bring many inconveniences and cost increases to the research and development process.

[0057] Figure 1A The structure schematic diagram of the nozzle with replaceable spray hole structure of one embodiment of the present application is shown. Figure 1B Figure 1A The sectional view I of the nozzle with replaceable spray hole structure. Figure 1C Figure 1A The sectional view II of the nozzle with replaceable spray hole structure. As shown in the figure, the nozzle with replaceable spray hole structure 100 mainly comprises a connecting seat 101, a nozzle body 102 and a locking nut 103.

[0058] ​​The bottom of the nozzle body 102 is in sealing fit with the top of the connecting seat 101, so as to ensure the sealing between the nozzle body 102 and the connecting seat 101.

[0059] The locking nut 103 is in threaded fit with the connecting seat 101, so as to realize the stable locking of the nozzle body 102 and the connecting seat 101.

[0060] It is worth noting that, since the nozzle bodies 102 of different structures are equipped with different spray hole structures, and the spray hole structure is directly related to the spraying effect.

[0061] In some examples, the bottom of the nozzle body 102 forms a stop shoulder 104, and the nozzle body 102 is in fit with the locking nut 103 through the stop shoulder 104. The locking nut 103 defines the moving range of the nozzle body 102 in the axial direction through the stop shoulder 104, so that the position of the nozzle body 102 relative to the connecting seat 101 is accurately anchored, providing guarantee for the accuracy of the entire assembly.

[0062] In some examples, the bottom of the nozzle body 102 and the top of the connecting seat 101 form a tapered surface sealing. The tapered surface sealing structure effectively blocks the leakage channel of the liquid or gas. With the increase of the internal pressure, the fit between the tapered surfaces becomes even tighter, having the self-adaptive sealing feature.

[0063] Figure 2A The structure diagram of the replaceable spray hole structure nozzle of another embodiment of the utility model is shown. Figure 2B is Figure 2A is a sectional view I. Figure 2C is Figure 2AFigure 2 is a sectional view II of the nozzle. As shown, the nozzle 200 and the nozzle structure are close, and the nozzle 200 mainly comprises a connecting seat 201, a nozzle body 202 and a locking nut 203. The bottom of the nozzle body 202 is in sealing fit with the top of the connecting seat 201, so as to ensure the sealing between the nozzle body 202 and the connecting seat 201. The locking nut 203 is in threaded fit with the connecting seat 201, so as to realize the stable locking of the nozzle body 202 and the connecting seat 201. The nozzle body 102 is replaceable to adjust the spraying effect.

[0064] Further, the nozzle 200 further comprises a gasket 205. The gasket 205 is arranged between the bottom surface of the nozzle body 202 and the top surface of the connecting seat 201, and the nozzle body 202 and the connecting seat 201 are sealed through the gasket 205. The gasket 205 can effectively prevent the leakage of liquid or gas at the connection between the nozzle body 202 and the connecting seat 201, so as to ensure the working efficiency and stability of the nozzle 200.

[0065] In some examples, the nozzle 200 further comprises a first sealing ring 206. The bottom periphery of the stop shoulder 204 and the top periphery of the connecting seat 201 form a first annular groove 207 for accommodating the first sealing ring 206. The first annular groove 207 provides a precise mounting position for the first sealing ring 206, so that the first sealing ring 206 can be embedded therein. After the first sealing ring 206 is mounted in the first annular groove 207, a peripheral sealing line is again arranged between the gasket 205 and the connecting seat 201. When the nozzle 200 is in a working state, the first sealing ring 206 can effectively prevent the leakage of gas or liquid from the connection between the nozzle body 202 and the connecting seat 201 due to its sealing property. Through the gasket 205 and the first sealing ring 206, the sealing performance of the nozzle 200 is ensured to be in the best state, so as to ensure the stable and efficient operation of the nozzle 200.

[0066] In some examples, the nozzle body 202 and / or the connecting seat 201 are provided with an angular positioning groove, and the angular relationship between the nozzle body 202 and the connecting seat 201 is determined through the angular positioning groove. When the nozzle body 202 and the connecting seat 201 are assembled, they are matched with each other through the angular positioning groove arranged on the respective contact surfaces. This matching manner enables the angular positioning groove to accurately limit the relative position of the nozzle body 202 and the connecting seat 201 in the angular direction, so as to ensure that the angular relationship between them is always fixed and accurate. In the actual working process of the nozzle 200, whether it is the spraying direction or other angular-related performance parameters, they can be controlled and guaranteed, so that the nozzle 200 can stably and efficiently exert its function to meet the test requirements.

[0067] In some examples, the nozzle 200 further comprises a second sealing ring 208. The connecting seat 201 is adapted to be arranged on the base structure 300, and the connecting seat 201 is sealed with the base structure 300 by the second sealing ring 208. Preferably, a second annular groove 209 is arranged on the bottom outer wall of the connecting seat 201, and the second annular groove 209 is adapted to accommodate the second sealing ring 208.

[0068] Similarly, referring to Figure 1C , the nozzle 100 further comprises a second sealing ring 108, and the connecting seat 101 is sealed with the base structure 300 by the second sealing ring 108. A second annular groove 109 is arranged on the bottom outer wall of the connecting seat 101, and the second annular groove 109 is adapted to accommodate the second sealing ring 108.

[0069] In some examples, referring to Figure 1C and Figure 2C , the locking nuts 103 and 203 are hexagonal nuts. As a widely used standard part, the hexagonal nut provides great convenience for installation and disassembly operations. The operator can easily tighten or loosen the locking nuts 103 and 203 by using a conventional wrench tool, thereby effectively controlling the fastening degree between the nozzles 102 and 202 and the connecting seats 101 and 201. This convenience is reflected in the assembly, maintenance of the nozzles 100 and 200, and the process of replacing the nozzle bodies 102 and 202 to adjust the spraying effect, ensuring that the entire nozzle system 100 and 200 can quickly complete the switching of the nozzle bodies 102 and 202 to meet the testing work requirements.

[0070] In some examples, the nozzle 100 further comprises a mounting seat 110 arranged on the connecting seat 101. The connecting seat 101 can be fixed to the base structure 300 through the mounting seat 110. Similarly, the nozzle 200 further comprises a mounting seat 210 arranged on the connecting seat 201. The connecting seat 201 can be fixed to the base structure 300 through the mounting seat 210.

[0071] It is obvious to those skilled in the art that various modifications and variations can be made to the above exemplary embodiments of the present application without departing from the spirit and scope of the present application. Therefore, it is intended to cover modifications and variations of the present application falling within the scope of the appended claims and their equivalents.
