Description

Technical Field

[0001] This invention relates to an oil flow selection structure with linkage function, belonging to the field of lubrication test technology for aero-engine gearbox transmission systems, and is applicable to different types of aero-engines. Background Technology

[0002] Lubrication tests are required for the gear meshing points and bearings of aircraft engine transmission gearboxes to verify the rationality of the lubrication flow design. Because the gearbox drives a large number of engine and aircraft accessories with significant differences in power and speed, the required lubricating oil flow rates for bearings and gear meshing points also vary considerably.

[0003] The traditional solution is to design a large number of fuel injectors with different flow rates, and then select the appropriate flow rate injector based on the design requirements to conduct lubrication tests at each lubrication point. This approach presents three problems:

[0004] 1. Due to the high temperature of the lubricating oil, replacing the fuel injector requires waiting for the lubricating oil to cool down, which takes more time and requires multiple people to operate;

[0005] 2. Failure to shut down a certain lubrication circuit in a timely manner will result in a large waste of lubrication oil;

[0006] 3. When all the oil injectors spray at the same time, the lubricating oil will splash from one lubrication point to the adjacent lubrication point, which will affect the accuracy of the test of the adjacent lubrication point. Summary of the Invention

Detailed Implementation

[0023] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0024] Example 1

[0025] like Figures 1 to 3 As shown, a lubricating oil flow selection structure with linkage function includes a button baffle 1 and an oil circuit slider 9. One side of the button baffle 1 and one side of the oil circuit slider 9 are connected by multiple flow selection buttons, and the two ends of the oil circuit slider 9 are respectively connected to the two ends of the button baffle 1 by translation springs 6. On one side of the last flow selection button, there is a switch button 5 connected to the button baffle 1 and the oil circuit slider 9. The oil circuit slider 9 is provided with a button slot 14. The flow selection button, the button slot 14, and the oil circuit slider 9 work together to achieve the function of selection and timely shutdown. One end of the oil circuit slider 9 is provided with an oil inlet 7, and the upper end surface of the oil circuit slider 9 is provided with a flow nozzle at the position corresponding to the flow selection button. The part of the flow selection button connected to the button baffle 1 is fitted with a return spring 8, and the part of the switch button 5 connected to the button baffle 1 is fitted with a return spring 8.

[0026] The flow nozzles include a first flow nozzle 11, a second flow nozzle 12, and a third flow nozzle 13.

[0027] The first flow nozzle 11, the second flow nozzle 12, and the third flow nozzle 13 are flow nozzles with a flow rate of 0.6 L / min, 0.8 L / min, and 1 L / min, respectively.

[0028] Furthermore, other flow nozzles can be added depending on lubrication requirements.

[0029] Specifically, the nozzle orifice diameter and oil inlet velocity of the flow nozzle determine the oil ejection velocity. The larger the flow nozzle orifice diameter, the faster the oil inlet velocity, and the larger the amount of oil ejected from the flow nozzle. By comprehensively considering the oil inlet velocity and the flow nozzle orifice diameter during the design, the required oil nozzle flow rate can be achieved.

[0030] Preferably, the direction of the flow nozzle is not fixed and can be adjusted according to the position of the object to be lubricated.

[0031] The traffic selection buttons include a first traffic selection button 2, a second traffic selection button 3, and a third traffic selection button 4.

[0032] The first flow rate selection button 2, the second flow rate selection button 3, and the third flow rate selection button 4 are respectively the flow rate selection buttons for 0.6L / min, 0.8L / min, and 1L / min.

[0033] The flow nozzle is connected to the oil inlet 7.

[0034] An oil passage plug 10 is provided at the connection between the oil inlet 7 and the flow nozzle.

[0035] The upper surface of the oil circuit slider 9 is composed of multiple inclined blocks that slope downwards. The inclination angle of the inclined blocks can be adjusted as needed. The button slot 14 is located on the lower side of the inclined blocks.

[0036] The flow nozzle is located inside the inclined block.

[0037] Furthermore, by placing the button slot 14 in the oil circuit slider 9, the structure of the flow selection button is simplified, and the utilization of the oil circuit slider 9 is effectively improved.

[0038] Example 2

[0039] The translation spring 6, the oil circuit slider 9 and the button baffle 1 form a horizontal translation mechanism for the oil circuit slider 9, providing horizontal translation movement for the oil circuit slider 9; the flow selection button and the rebound spring 8 form an oil circuit flow selection switch, providing vertical downward and rebound movement for the flow selection button.

[0040] By using the translation spring 6 and the button baffle 9, the flow nozzles with different orifice diameters in the oil circuit slider and the flow selection button are combined into a mechanism with linkage function to quantitatively output the lubricating oil flow and shut off the other oil injectors in time. By pressing down the switch button 5, the flow selection button is disengaged from the button slot 14 and springs back to reset, thus blocking all oil injectors. This simplifies the operation process and saves manpower.

[0041] By pressing the desired oil flow rate selection button, the oil circuit slider 9 moves in the opposite direction to the flow rate selection button under the squeezing action of the flow rate selection button. The flow rate selection button moves down along the inclined block of the oil circuit slider 9 and is finally fixed in the button slot 14. The other flow rate selection buttons are reset by the return spring 8 to block the flow nozzle of their respective oil circuit, thus realizing the function of selection and shutdown.

[0042] Example 3

[0043] The lubricating oil enters through the oil inlet 7 and is stored in the lubricating oil passage of the oil circuit slider 9. The oil circuit slider 9 provides three different first flow nozzles 11, second flow nozzles 12, and third flow nozzles 13 with flow rates of 0.6L / min, 0.8L / min, and 1L / min. The flow nozzle is selected according to the required lubricating oil flow rate.

[0044] For example, if the oil flow rate is currently spraying oil at 0.8 L / min and needs to be adjusted to 0.6 L / min for lubrication, pressing the first flow rate selection button 2 causes the oil circuit slider 9 to move horizontally under the compression of the translation spring 6, as the first flow rate selection button 1 is pressed down. At this time, the first flow rate selection button 1 slides down the inclined block of the oil circuit slider 9 and moves vertically downwards, while the second flow rate selection button 3 disengages from the button slot 14. When the first flow rate selection button 1 slides into the button slot 14, the oil circuit slider 9 quickly rebounds to its original position under the elastic force of the translation spring 6. At this time, the first flow rate selection button 1 is locked in the oil circuit button slot 14, and the first flow nozzle 11, without the first flow rate selection button 1 blocking it, performs oil spraying. The second flow rate selection button 3 blocks the 0.8 L / min oil flow nozzle.

[0045] Specifically, when the oil circuit finishes working, press the switch button 5. Under the pressure of the switch button 5, the oil circuit slider 9 moves horizontally. When the oil circuit slider 9 moves a certain distance, the first flow selection button 1 slides out of the button slot 14 and rebounds under the action of the spring force of the return spring 8 and resets to the first flow nozzle 11 to block the oil circuit and stop the release of lubricating oil.
