Abstract
Description
Technical Field
[0001] This invention belongs to the field of vibration reduction equipment technology, specifically relating to a vibration reduction device for aircraft motor installation. Background Technology
[0002] As a core power component, the operating stability of the motor directly affects the flight safety and comfort of the entire aircraft. When operating, aircraft motors generate continuous vibrations due to electromagnetic losses and mechanical friction. These vibrations are transmitted to the base or supporting structure of the aircraft, and then to the surrounding foundation or other supporting structures, resulting in the spread of noise and vibration. If the vibration is not effectively suppressed, it will not only cause fatigue damage to the components of the aircraft motor itself, but also transmit the vibration to the fuselage through the installation structure, causing fuselage resonance, excessive cabin noise, and even interference with the normal operation of in-flight electronic equipment. Therefore, a vibration damping device is usually installed at the installation site of aircraft motors.
[0003] The maintenance of existing vibration damping devices often requires manual disassembly and installation of the outer casing, adjustment of the friction plates, and manual application of grease. The operation process is cumbersome and requires highly skilled maintenance personnel. Especially in the compact installation space of aviation equipment, the difficulty of manual operation is further increased. Not only are problems such as uneven lubrication and component misalignment prone to occur, but maintenance errors may also lead to secondary failures of the device, affecting the normal start-up and operation of the motor, making it difficult to effectively improve maintenance efficiency. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a vibration damping device for aircraft motor mounting.
[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: a vibration damping device for aircraft motor installation, including a mounting base housing, on which multiple sets of mounting slots are symmetrically opened, and motor connecting seats are respectively arranged in the multiple sets of mounting slots. Vibration damping components are respectively arranged at the lower end of the motor connecting seats, and the upper end of the motor connecting seats is fixedly installed with the motor. Connecting blocks are symmetrically fixedly connected to both sides of the mounting base housing, and the mounting base housing is installed with the aircraft body through the connecting blocks. Multiple sets of maintenance components are respectively installed inside the mounting base housing, and a drive component is arranged on one side of the multiple sets of maintenance components. The positions of the maintenance components and the motor connecting seats correspond to each other.
[0006] Furthermore, the vibration damping component includes a fixed base that is fixedly installed with the housing of the mounting base. A limiting moving column is slidably connected inside the fixed base. A positioning guide is fixedly installed on the upper end of the limiting moving column. A clamping seat is fixedly connected to the upper end of the positioning guide. A lower friction plate is fixedly connected to the end of the clamping seat away from the positioning guide. An upper friction plate is provided on the upper end of the lower friction plate. The teeth on the contact surfaces of the upper friction plate and the lower friction plate mesh with each other. A motor connecting seat is fixedly connected inside the upper friction plate. A buffer spring is fixedly installed on the upper surface of the limiting moving column. The end of the buffer spring away from the limiting moving column is fixedly installed to the lower end of the clamping seat.
[0007] Through the above technical solution, the vibration of the motor connecting seat drives the upper and lower friction plates to move relative to each other. The sliding friction between the upper and lower friction plates consumes the kinetic energy generated by the motor vibration. Then, the damping stability of the vibration damping component is maintained by the pre-tightening compensation of the elastic deformation of the buffer spring, thereby achieving the purpose of weakening vibration and reducing noise. The buffer spring pushes upward against the seat, and the axial pre-tightening force is generated by the elastic deformation of the buffer spring, which presses the lower friction plate tightly against the surface of the upper friction plate at the lower end of the motor connecting seat, so that the slight wear between the lower and upper friction plates can be compensated when the motor vibrates.
[0008] Furthermore, the maintenance component includes a mounting shaft fixedly connected to the mounting base housing, two rotating shaft blocks rotatably connected to the mounting shaft, mounting half-cylinders fixedly connected to the two rotating shaft blocks respectively, strong magnetic strips fixedly connected to the two mounting half-cylinders respectively, positioning cylinders fixedly connected inside the mounting half-cylinders, and positioning holes provided at the upper end of the mounting half-cylinders.
[0009] Through the above technical solution, the strong magnetic strip can assist the two mounting half-cylinders in achieving rapid and stable closed positioning. When the mounting half-cylinders rotate to a position close to the closed position, the strong magnetic force between the strong magnetic strips will generate an attraction force, pulling the two strong magnetic strips to quickly align and fit together. When the mounting half-cylinders on both sides are combined, the positioning cylinder can push the position of the motor connecting seat and the lower friction plate at the center of the mounting half-cylinders back to be aligned, avoiding the situation where the motor connecting seat and the lower friction plate have large movement deviations during use.
[0010] Furthermore, a lubrication cavity is provided inside the installation half-cylinder, a connecting seat is fixedly connected to the lower surface of the installation half-cylinder, a flow pipe is provided inside the installation half-cylinder, the flow pipe is interconnected with the lubrication cavity, a micro pump is fixedly connected to the flow pipe, a variable installation cavity is provided at the lower end of the installation half-cylinder, a moving block is slidably connected inside the variable installation cavity, a connecting pipe is provided inside the moving block, a return spring is fixedly connected to one side of the moving block, a connecting pipe is provided inside the connecting seat, the connecting pipe is inclined, an atomizing nozzle is fixedly connected to the inner side of the connecting seat, and the connecting pipe is interconnected with the flow pipe.
[0011] With the above technical solution, after the installation half-cylinder is fully merged, the position of the connecting pipe and the flow pipe are interconnected. The lubricating fluid inside the lubrication chamber is sprayed out from the atomizing nozzle at one end of the connecting pipe by the action of the micro pump, and lubricates and maintains the lower part of the vibration damping component. When the installation half-cylinder is rotated open, the moving block loses pressure and slides outward under the action of the return spring, so that the connecting pipe and the flow pipe are blocked again, and the lubrication channel is automatically blocked.
[0012] Furthermore, the drive assembly includes a mounting bracket fixedly mounted to the upper surface of the mounting base housing. One end of the mounting bracket is fixedly connected to a support base, and one side of the support base is fixedly connected to a support shaft. The outer wall of the support shaft is rotatably connected to a first connecting sleeve and a second connecting sleeve. The outer sides of the first and second connecting sleeves are respectively fixedly connected to a first fixing arm and a second fixing arm. The ends of the first and second fixing arms away from the support shaft are respectively rotatably connected to two mounting half-cylinders. The outer wall of the support shaft is also equipped with mounting torsion springs corresponding to the first and second connecting sleeves. Mounting protrusions are fixedly connected to the first and second connecting sleeves respectively.
[0013] Through the above technical solution, the outer wall of the support shaft is equipped with mounting torsion springs corresponding to the first fixed arm and the second fixed arm. Under the elastic action of the mounting torsion springs, the first fixed arm and the second fixed arm can be automatically reset, which in turn can drive the mounting half cylinders on both sides to automatically close.
[0014] Furthermore, a drive motor is fixedly mounted on the support base, and a drive gear is fixedly connected to the output end of the drive motor. A driven gear is meshed with one side of the drive gear. The driven gear and the drive gear are rotatably connected to the support base, respectively. A mounting winch is fixedly connected to the center position of both the driven gear and the drive gear. Steel ropes are wound around the outer walls of both mounting winches. The end of the steel rope away from the mounting winch is fixedly mounted to a connector. The connector is rotatably connected to a mounting protrusion. A fixing column is rotatably connected to each of the two mounting winches. The fixing column is fixedly mounted to the outer shell of the mounting base.
[0015] Through the above technical solution, the meshing between the driving gear and the driven gear enables the two installation winches to rotate synchronously. The two installation winches on both sides drive the steel rope to continuously wind. During the tightening process, the two steel ropes can drive the two installation half-cylinders to rotate and open around the support shaft again through the positioning plugs of the first fixed arm and the second fixed arm, respectively, so that the device can work normally.
[0016] Furthermore, positioning plug-in pins are respectively fixedly installed at the ends of the first and second fixed arms away from the support shaft, and the position of the positioning hole at the upper end of the mounting half-cylinder corresponds to the position of the positioning plug-in pin.
[0017] Furthermore, a mounting door is installed on one side of the mounting base housing, and a heat dissipation hole is provided at the lower end of the mounting door. The mounting door is fixedly installed to the mounting base housing by multiple sets of fixing bolts.
[0018] Through the above technical solution, the core function of the heat dissipation holes is to create an air circulation channel inside the mounting base housing, so as to timely dissipate the heat generated by the motor and vibration damping components during operation, and avoid excessive internal temperature leading to component performance degradation or failure.
[0019] The beneficial effects of the present invention are as follows: (1) The present invention designs a matching maintenance component and a drive component. When the installation half-cylinder is completely merged, the position of the connecting pipe and the flow pipe are interconnected. The lubricating fluid inside the lubrication chamber is sprayed out from the atomizing nozzle at one end of the connecting pipe under the action of the micro pump, and lubricates and maintains the lower part of the vibration damping component. When the installation half-cylinder is rotated open, the moving block loses pressure and slides outward under the action of the reset spring, so that the connecting pipe and the flow pipe are blocked again, and the lubrication channel is automatically blocked, avoiding the lubricating fluid from being sprayed dry in the non-working state. Furthermore, the setting of the maintenance component can greatly reduce the wear rate of the device and greatly extend the replacement cycle of the vibration damping component; (2) The present invention sets a vibration damping component. The vibration of the motor connector causes the upper and lower friction plates to move relative to each other. The sliding friction between the upper and lower friction plates consumes the kinetic energy generated by the motor vibration. The damping stability of the vibration damping component is maintained by the pre-tightening compensation of the elastic deformation of the buffer spring, thereby achieving the purpose of weakening vibration and reducing noise. The buffer spring pushes the seat upward, and the axial pre-tightening force generated by the elastic deformation of the buffer spring is used to press the lower friction plate tightly against the surface of the upper friction plate at the lower end of the motor connector. This allows the slight wear between the lower and upper friction plates to be compensated when the motor vibrates. At the same time, the buffer spring can also buffer and absorb the radial vibration generated by the aircraft motor, further eliminating the vibration generated when the aircraft motor starts up and maintaining the stability of the fuselage.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0031] like Figures 1-2 As shown, a vibration damping device for aircraft motor mounting in this embodiment includes a mounting base housing 1. Multiple sets of mounting slots 11 are symmetrically formed on the mounting base housing 1. Motor connecting seats 2 are respectively arranged in the multiple sets of mounting slots 11. Vibration damping components 5 are respectively arranged at the lower end of the motor connecting seats 2. The upper end of the motor connecting seats 2 is fixedly mounted to the motor. Connecting blocks 15 are symmetrically fixedly connected to both sides of the mounting base housing 1, and the mounting base housing 1 is mounted to the aircraft body through the connecting blocks 15. Multiple sets of maintenance components 3 are respectively installed inside the mounting base housing 1. A drive component 4 is arranged on one side of each set of maintenance components 3. The positions of the maintenance components 3 and the motor connecting seats 2 correspond to each other.
[0032] like Figures 1-9 As shown, the vibration damping assembly 5 includes a fixed base 50 fixedly installed with the mounting housing 1. A limiting moving post 51 is slidably connected inside the fixed base 50. A positioning guide 52 is fixedly installed on the upper end of the limiting moving post 51. A pressing seat 54 is fixedly connected to the upper end of the positioning guide 52. A lower friction plate 55 is fixedly connected to the end of the pressing seat 54 away from the positioning guide 52. An upper friction plate 56 is provided on the upper end of the lower friction plate 55. The teeth on the contact surfaces of the upper friction plate 56 and the lower friction plate 55 mesh with each other. A motor connecting seat 2 is fixedly connected inside the upper friction plate 56. A buffer spring 53 is fixedly installed on the upper surface of the limiting moving post 51. The end of the buffer spring 53 away from the limiting moving post 51 is connected to the pressing seat. The lower end of 54 is fixedly installed. The vibration of the motor connecting seat 2 drives the upper friction plate 56 and the lower friction plate 55 to move relative to each other. The kinetic energy generated by the motor vibration is consumed by the mutual sliding friction between the upper friction plate 56 and the lower friction plate 55. Then, the damping stability of the vibration damping component 5 is maintained by the pre-tightening compensation of the elastic deformation of the buffer spring 53, thereby achieving the purpose of weakening vibration and reducing noise. The buffer spring 53 pushes upward against the seat 54, and the axial pre-tightening force is generated by the elastic deformation of the buffer spring 53, which presses the lower friction plate 55 tightly against the surface of the upper friction plate 56 at the lower end of the motor connecting seat 2, so that the slight wear between the lower friction plate 55 and the upper friction plate 56 can be compensated when the motor vibrates.
[0033] like Figures 1-7As shown, the maintenance component 3 includes a mounting shaft 313 fixedly connected to the mounting base housing 1. Two rotating shaft blocks 314 are rotatably connected to the mounting shaft 313. Mounting half-cylinders 30 are fixedly connected to the two rotating shaft blocks 314 respectively. Strong magnetic strips 31 are fixedly connected to the two mounting half-cylinders 30 respectively. Positioning cylinders 32 are fixedly connected inside the mounting half-cylinders 30 respectively. Positioning holes 33 are opened at the upper end of the mounting half-cylinders 30. The strong magnetic strips 31 can assist the two mounting half-cylinders 30 to achieve quick and stable closed positioning. When the mounting half-cylinders 30 rotate to a position close to the closed position, the strong magnetic force between the strong magnetic strips 31 will generate an attraction force, pulling the two strong magnetic strips 31 to quickly align and fit together. When the mounting half-cylinders 30 on both sides are closed, the positioning cylinders 32 can push the position of the motor connecting seat 2 and the lower friction plate 55 at the center position of the mounting half-cylinder 30 back to align, avoiding the situation where the motor connecting seat 2 and the lower friction plate 55 have large movement deviations during use.
[0034] like Figures 1-6 As shown, a lubrication cavity 34 is provided inside the mounting half-cylinder 30. A connecting seat 36 is fixedly connected to the lower surface of the mounting half-cylinder 30. A flow pipe 35 is provided inside the mounting half-cylinder 30, and the flow pipe 35 is interconnected with the lubrication cavity 34. A micro pump 38 is fixedly connected to the flow pipe 35. A variable mounting cavity 39 is provided at the lower end of the mounting half-cylinder 30. A moving block 310 is slidably connected inside the variable mounting cavity 39. A connecting pipe 311 is provided inside the moving block 310. A return spring 312 is fixedly connected to one side of the moving block 310. A connecting pipe 37 is provided inside the connecting seat 36. The connecting pipe 37 is inclined. An atomizing nozzle is fixedly connected to the inner side of the 36. The connecting pipe 37 and the flow pipe 35 are interconnected. When the installation half-cylinder 30 is completely closed, the position of the connecting pipe 311 and the flow pipe 35 are interconnected. The lubricating fluid inside the lubrication chamber 34 is sprayed out from the atomizing nozzle at one end of the connecting pipe 37 through the pipe under the action of the micro pump 38 to lubricate and maintain the lower part of the vibration damping component 5. When the installation half-cylinder 30 is rotated open, the moving block 310 loses pressure and slides outward under the action of the return spring 312, so that the connecting pipe 311 and the flow pipe 35 are blocked again, and the lubrication channel is automatically blocked.
[0035] like Figures 1-8As shown, the drive assembly 4 includes a mounting bracket 40 fixedly mounted to the upper surface of the mounting base housing 1. One end of the mounting bracket 40 is fixedly connected to a support base 41. One side of the support base 41 is fixedly connected to a support shaft 43. The outer wall of the support shaft 43 is rotatably connected to a first connecting sleeve 44 and a second connecting sleeve 46. The outer sides of the first connecting sleeve 44 and the second connecting sleeve 46 are respectively fixedly connected to a first fixing arm 45 and a second fixing arm 47. The ends of the first fixing arm 45 and the second fixing arm 47 away from the support shaft 43 are respectively rotatably connected to two mounting half cylinders 30. The outer wall of the support shaft 43 is also equipped with mounting torsion springs 48 corresponding to the first connecting sleeve 44 and the second connecting sleeve 46. Mounting protrusions 49 are fixedly connected to the first connecting sleeve 44 and the second connecting sleeve 46. The outer wall of the support shaft 43 is equipped with mounting torsion springs 48 corresponding to the first fixing arm 45 and the second fixing arm 47. Under the elastic action of the mounting torsion springs 48, the first fixing arm 45 and the second fixing arm 47 can be automatically reset, thereby automatically closing the mounting half cylinders 30 on both sides.
[0036] like Figures 1-5 As shown, a drive motor 42 is fixedly mounted on the support base 41. A drive gear 414 is fixedly connected to the output end of the drive motor 42. A driven gear 413 is meshed with one side of the drive gear 414. The driven gear 413 and the drive gear 414 are rotatably connected to the support base 41. A winch 412 is fixedly connected to the center of both the driven gear 413 and the drive gear 414. Steel ropes 411 are wound around the outer walls of both winches 412. The end of the steel rope 411 away from the winch 412 is fixedly mounted to a connector 410. The connector 410 is rotatably connected to a mounting protrusion 49. A fixing post 415 is rotatably connected to each of the two winches 412. 5 is fixedly installed between the mounting base housing 1 and the drive gear 414 and driven gear 413. Due to the meshing between the drive gear 414 and driven gear 413, the two mounting winches 412 can rotate synchronously. The two mounting winches 412 drive the steel rope 411 to continuously wind through the two sides. During the tightening process, the two steel ropes 411 can drive the two mounting half cylinders 30 to rotate and open around the support shaft 43 again through the positioning plugs of the first fixed arm 45 and the second fixed arm 47, respectively, so that the device can work normally. The first fixed arm 45 and the second fixed arm 47 are respectively fixedly installed with positioning plugs at the ends away from the support shaft 43. The position of the positioning hole 33 at the upper end of the mounting half cylinder 30 corresponds to the position of the positioning plug.
[0037] like Figures 1-2As shown, a mounting door 12 is installed on one side of the mounting base housing 1. A heat dissipation hole 13 is provided at the lower end of the mounting door 12. The mounting door 12 is fixedly installed to the mounting base housing 1 by multiple sets of fixing bolts 14. The core function of the heat dissipation hole 13 is to create an air circulation channel inside the mounting base housing 1, so as to timely dissipate the heat generated by the motor and vibration damping components 5 during operation, and avoid excessive internal temperature leading to component performance degradation or failure.
[0038] The working principle of this embodiment is as follows: When the device needs maintenance, the output shaft of the drive motor 42 rotates, which in turn drives the two mounting winches 412 to rotate synchronously, so that the two steel ropes 411 are slowly released. The outer wall of the support shaft 43 is equipped with mounting torsion springs 48 corresponding to the first fixed arm 45 and the second fixed arm 47. Under the elastic action of the mounting torsion springs 48, the first fixed arm 45 and the second fixed arm 47 can be automatically reset, which can then drive the mounting half cylinders 30 on both sides to close automatically. When the mounting half cylinders 30 on both sides are closed, the positioning cylinder 32 can push the position of the motor connecting seat 2 and the lower friction plate 55 at the center position of the mounting half cylinder 30 back to align, so as to avoid the situation that the motor connecting seat 2 and the lower friction plate 55 have large movement deviations during use.
[0039] Simultaneously, when the half-cylinder 30 is closed, the moving block 310 will slide into the changing installation cavity 39 under the pressure of the motor connecting seat 2. After the half-cylinder 30 is completely closed, the position of the connecting pipe 311 and the flow pipe 35 are connected to each other. The lubricating fluid inside the lubrication cavity 34 is sprayed out from the atomizing nozzle at one end of the connecting pipe 37 through the pipe under the action of the micro pump 38, and lubricates and maintains the lower part of the vibration damping component 5. When the half-cylinder 30 is rotated open, the moving block 310 loses pressure and slides outward under the action of the return spring 312, so that the connecting pipe 311 and the flow pipe 35 are blocked again.
[0040] After lubrication, the output shaft of the drive motor 42 rotates in the opposite direction, driving the drive gear 414 to rotate. Since the drive gear 414 and the driven gear 413 mesh with each other, the two mounting winches 412 can rotate synchronously. The two mounting winches 412 drive the steel rope 411 to continuously wind around. During the tightening process, the two steel ropes 411 can drive the two mounting half-cylinders 30 to rotate around the support shaft 43 again through the positioning plugs of the first fixed arm 45 and the second fixed arm 47, respectively, so that the device can work normally.
[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
