Technical Field

[0001] This utility model belongs to the field of aviation gear technology, specifically relating to wear-resistant aviation gears. Background Technology

[0002] Aviation gears are high-performance, high-reliability gears used in key components such as aero engines, helicopter main / tail gearboxes, auxiliary power units (APUs), aircraft landing gear retraction and extension systems, and flap control systems. They are not just ordinary metal parts, but cutting-edge products that integrate materials science, precision manufacturing, heat treatment technology, surface engineering, and simulation analysis.

[0003] In the process of developing this application, the inventors discovered that the technology has at least the following problems: existing aircraft gears will wear or be damaged due to excessive friction during long-term operation, affecting their service life and operating costs; therefore, further improvements can be made. Summary of the Invention

[0004] In view of the problem that existing aircraft gears in the background art will wear or be damaged due to excessive friction during long-term operation, which affects their service life and operating costs, this application provides a wear-resistant aircraft gear. This utility model provides efficient protection for the gear teeth by setting a detachable protective shell, and also sets an oil outlet component to play a certain lubrication role during gear operation, preventing excessive wear of the gear during long-term operation, which affects its service life and operating costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] Wear-resistant aircraft gear includes a gear body with multiple teeth distributed around its outer circumference. A shaft groove is formed at the center of the gear body. Multiple through slots are provided on the gear body, which correspond to each tooth. A protective shell is fitted onto each tooth. Multiple oil outlet components are provided inside the gear body near the outer wall of the gear, and the oil outlet components are located between two adjacent teeth.

[0007] Furthermore, the protective shell includes a front shell and a rear shell, the top ends of which are rotatably connected by a pivot. A cavity is provided between the front shell and the rear shell, and the cavity contains the gear teeth and the side of the gear body close to the gear teeth. Corresponding connecting blocks are provided at the bottom of the front shell and the rear shell, and the connecting blocks are connected by bolts. Both the connecting blocks and the bottom of the protective shell are set in the through groove of the gear body.

[0008] Furthermore, the inner wall of the protective shell is provided with a soft rubber layer.

[0009] Furthermore, the oil outlet assembly includes an oil reservoir disposed inside the gear body, the oil reservoir having an oil storage chamber inside, an opening communicating with the outside at one end of the oil reservoir near the outside of the gear body, multiple drive cylinders disposed at the bottom of the oil reservoir, a horizontally placed push plate disposed inside the oil reservoir, and movable grooves accommodating the movement of the push plate at both ends of the inner sidewall of the oil reservoir, the sides of the push plate fitting against the inner sidewall of the movable groove, and the bottom of the push plate connected to the top of the drive cylinder.

[0010] Furthermore, at least one pressure sensor is provided at the top of the inside of the oil tank, and an alarm light electrically connected to the pressure sensor is provided above the gear body.

[0011] Furthermore, a ball bearing is placed inside the opening of the oil tank, with the center of the ball bearing located on the side of the opening close to the oil storage chamber. An arc-shaped bracket with the same center as the ball bearing is provided on the outer side wall of the gear body corresponding to the opening. The ball bearing will not fall out when it rolls inside the opening due to the restriction of the arc-shaped bracket.

[0012] The beneficial effects of this utility model are:

[0013] When the protective shell needs to be installed or removed, remove the gear, and open the front and rear shells by rotating the shaft. This allows for quick disassembly of the protective shell, increases the service life of the gear, and reduces operating costs.

[0014] The drive cylinder is activated, and it slowly and uniformly moves the push plate toward the opening of the oil tank. The oil tank contains lubricating oil between the push plate and the opening, which pushes the lubricating oil out of the opening to lubricate the gears. When the push plate moves to the pressure sensor, the pressure sensor is pressed and sends a signal to the internal controller of the gear (not shown). The alarm light flashes to warn the staff in time. The staff then activates the drive cylinder to reset the gears and refills the oil tank with lubricating oil. The lubricating oil increases the service life of the gears and reduces operating costs. Attached Figure Description

[0021] Example 1, referring to Figure 1-2 This utility model includes a gear body 1, with multiple teeth 2 distributed around its outer circumference. A shaft groove 3 is formed at the center of the gear body 1. Multiple through grooves 4 are formed on the gear body 1, corresponding to each tooth 2. A protective shell 5 is fitted onto each tooth 2. The protective shell 5 includes a front shell 501 and a rear shell 502. The top ends of the front shell 501 and the rear shell 502 are rotatably connected by a rotating shaft 7. A cavity 8 is formed between the front shell 501 and the rear shell 502. The tooth 2 and the tooth are enclosed in the cavity 8. On the side of the gear body 1 close to the tooth 2, the front shell 501 and the rear shell 502 are directly provided with corresponding connecting blocks 9 at their bottoms. The connecting blocks 9 are connected by bolts 10. The bottoms of the connecting blocks 9 and the protective shell 5 are both set in the through groove 4 of the gear body 1. The inner side wall of the protective shell 5 is provided with a soft rubber layer 11. When it is necessary to install or remove the protective shell 5, the gear is removed, and the front shell 501 and the rear shell 502 are opened by rotating the shaft 7, which can realize the quick disassembly of the protective shell 5, increase the service life of the tooth 2, and reduce operating costs.

[0022] Reference Figure 1 and Figure 3Multiple oil outlet components 6 are provided inside the gear body 1 near the outer wall of the gear, and the oil outlet components 6 are located between two adjacent teeth 2. The oil outlet components 6 include an oil reservoir 601 inside the gear body 1, an oil storage chamber 602 inside the oil reservoir 601, an opening 603 communicating with the outside at the end of the oil reservoir 601 near the outer wall of the gear body 1, multiple drive cylinders 604 at the bottom of the oil reservoir 601, a horizontally placed push plate 605 inside the oil reservoir 601, and moving grooves 606 at both ends of the inner wall of the oil reservoir 601 to accommodate the movement of the push plate 605. The sides of the push plate 605 are attached to the inner wall of the moving groove 606, and the bottom of the push plate 605 is connected to the top of the drive cylinder 604. At least one pressure sensor 607 is provided at the top of the oil reservoir 601, and a pressure sensor 607 is located above the gear body 1. The electrically connected alarm light 608 activates the drive cylinder 604. The drive cylinder 604 slowly and uniformly moves the push plate 605 toward the opening 603 of the oil tank 601. The oil tank 601 contains lubricating oil between the push plate 605 and the opening 603. The lubricating oil flows out from the opening 603 to lubricate the gears. When the push plate 605 moves onto the pressure sensor 607, the pressure sensor 607 is pressurized and sends a signal to the internal controller of the gear (not shown). The alarm light 608 flashes to provide timely warning to the staff. The staff then activates the drive cylinder 604 to reset the gears and refills the oil tank 601 with lubricating oil. The lubricating oil increases the service life of the gears and reduces operating costs.

On the outer side of the gear body 1, corresponding to the opening 603, there is an arc-shaped support 13 with the same center as the ball bearing 12. The ball bearing 12 rolls inside the opening 603 and will not fall off due to the restriction of the arc-shaped support 13. The placement of the ball bearing 12 inside the opening 603 reduces the leakage of lubricating oil and increases the service life of the lubricating oil. Moreover, the ball bearing 12 rolls during gear operation without affecting the leakage of lubricating oil, effectively protecting the gear.
