Description

Technical Field

[0001] This utility model belongs to the field of aero-engine rotor technology, and more specifically, relates to an aero-engine rotor lubrication and balancing device. Background Technology

[0002] An aircraft rotary engine (usually referring to a rotary engine or rotary combustion engine) is a type of engine that uses a rotating piston. Unlike traditional reciprocating piston engines, its working principle is based on a triangular rotor rotating within an elliptical combustion chamber, completing the four stages of intake, compression, combustion, and exhaust. The rotary engine uses the rotational motion of a triangular rotor to control compression and exhaust, which is quite different from the linear motion of a traditional reciprocating piston engine. It has advantages such as simple structure, stable operation, and low vibration. During operation, a lubrication supply structure is needed to lubricate the rotor and cylinder, reducing wear and tear on components.

[0003] However, this product still has some problems. The existing lubrication supply structure usually uses an oil pump to spray lubricating oil in a metered manner. In order to avoid insufficient lubrication coverage, which would lead to inadequate lubrication of the rotor and cause wear, the existing counterweight design has a direct impact on the balance, stability and performance of the engine. However, after the existing counterweight is installed, the vibration generated by the continuous rotation of the rotor can easily make the rotor itself loose, resulting in unstable counterweight installation.

Detailed Implementation

Among them, rotating grooves are provided on the outer side of the rotor body 1 in the three included directions, and a spraying lubrication wheel 12 is rotatably installed in each rotating groove.

Rotating rods 121 are provided at the upper and lower ends of the spraying lubrication wheel 12, and the rotating rods 121 are rotatably connected to the body of the spraying lubrication wheel 12.

[0025] In this design, a placement groove 11 is provided on the rotor body 1 to ensure that the lubrication balance component 3 can be securely installed in the designated position, preventing loosening due to vibration during high-speed rotation and enhancing the stability and safety of the overall structure. A spray lubrication wheel 12 is provided on the outer side of the rotor body 1, continuously releasing lubricating oil through an oil storage cotton layer to form a uniform lubrication film, effectively reducing friction and localized wear, and improving the continuity and comprehensiveness of lubrication. The spray lubrication wheel 12 is rotatably connected via a rotating rod 121, allowing it to adapt to the rotor's motion state, maintain close contact with the cylinder inner wall, ensure uniform lubrication application, and avoid lubrication dead zones.

[0026] Specifically, the gear ring 2 is fixedly disposed within the through hole of the rotor body 1, and multiple slots 21 are formed on the outer periphery of the gear ring 2, which abut against the inner periphery of the through hole of the rotor body 1. It should be noted that the multiple slots 21 here can be used for heat dissipation or as a counterweight in the rotor body 1.

[0027] In this design, a gear ring 2 is set in the middle of the rotor body 1, and through the design of the slot 21, not only is the structural strength of the rotor enhanced, but also the functions of heat dissipation and auxiliary balancing are provided, which helps to improve the overall performance and durability of the engine.

[0028] Specifically, the lubrication balancing mechanism 3 is provided with three placement slots 11. The lubrication balancing mechanism 3 includes a lubrication balancing component 31. The outer periphery of the lubrication balancing component 31 is provided with external thread teeth 311, which are threadedly connected to the internal thread groove 112. Among them, the lower middle part of the lubrication balancing component 31 is fixedly provided with a mating groove 312, which matches with the mating protrusion 111 so as to be inserted into the mating protrusion 111 through the mating groove 312. The lubrication balancing component 31 has a cavity 32 inside.

A wide oil outlet 331 is provided at the end of the oil injection pipe 33, and an oil outlet groove 332 is provided at the outlet end of the wide oil outlet 331 so that the lubricating oil in the storage tank 322 can be sprayed into the oil outlet groove 332 through the oil outlet 324 and directed towards the spray lubrication wheel 12.

[0029] The lubrication balancing mechanism 3 in this design integrates lubrication and balancing functions. The balance block 321 within the lubrication balancing component 31 provides counterweight, effectively improving the rotor's stability during high-speed rotation. Simultaneously, lubricating oil in the reservoir 322 is continuously discharged to the lubrication points through the oil outlet 324, achieving automatic lubrication, reducing wear between the rotor and cylinder, and extending engine life. The lubrication balancing mechanism 3 is positioned at three angular directions on the rotor body 1, ensuring dynamic balance of the rotor during operation, dispersing centrifugal force, significantly reducing vibration and noise, and improving engine stability and reliability. Furthermore, the threaded connection between the internal thread groove 112 and the external thread teeth 311 enables quick installation and disassembly of the lubrication balancing component 3, facilitating maintenance and replacement. The threaded connection also has self-locking properties, ensuring a secure connection that is not easily loosened. The matching design of the mating protrusion 111 and the mating groove 312 provides precise positioning and guidance, ensuring accurate alignment of the lubrication balancing component 3 during installation, preventing misalignment, and further enhancing installation stability and reliability. The oil outlet 324 connects to the oil injection pipe 33, and the structural design of the widened oil port 331 and the oil outlet groove 332 expands the coverage area of ​​the lubricating oil, allowing the lubricating oil to be sprayed more evenly and precisely onto the lubrication points, thus improving lubrication efficiency and effectiveness. The storage tank 322 is equipped with an oil injection port 323, which is normally closed, facilitating the periodic addition of lubricating oil without affecting normal operation, while preventing lubricating oil leakage, ensuring the long-term effectiveness of the lubrication system and convenient maintenance.

[0030] Working principle:

[0031] During operation, the rotor body 1 rotates, and the balance block 321 in the lubrication balancing mechanism 3 provides counterweight to ensure the dynamic balance of the rotor under high-speed operation. Simultaneously, lubricating oil in the reservoir 322 is discharged through the oil outlet 324, sprayed through the oil injection pipe 33 and the wide oil outlet 331 into the oil outlet cavity 332, and then conveyed towards the spray lubrication wheel 12. The spray lubrication wheel 12 absorbs lubricating oil through the oil storage cotton layer and evenly coats the inner wall of the engine cylinder as the rotor rotates, forming a continuous lubricating film. The slots 21 on the gear ring 2 help with heat dissipation and assist in balancing. The entire device achieves an organic combination of lubrication and balancing, improving rotor stability and reducing vibration while ensuring effective lubrication of critical parts, thereby reducing wear and extending engine life.
