Description

Technical Field

[0001] This invention relates to the field of aviation motor technology, specifically to an aviation starter motor with moisture-proof function. Background Technology

[0002] The starter motor is a core component of the aircraft engine starting system, and its performance directly affects the engine's starting reliability, response speed, and the overall operational safety of the aircraft. In the aviation field, engine starting requires overcoming enormous inertia in a short time to achieve a rapid transition from a standstill to a stable speed. Therefore, extremely high requirements are placed on the starter motor's power density, starting torque, resistance to high and low temperatures, vibration and shock resistance, and reliability.

[0003] Traditional aircraft starter motors mostly adopt DC brushed motor structures. Although they have the advantages of simple control and large starting torque, they suffer from wear problems caused by mechanical contact between the brushes and the commutator, which shortens the motor's service life. At the same time, their torque performance is relatively poor when facing some high resistance and rigid starts, which can even damage the motor. Furthermore, if a fault occurs during operation, due to the special working environment, timely repair is not possible. Therefore, developing a starter motor that can adapt to the extreme working conditions of aviation and has both high reliability and high power density has become an important research direction in the field of aviation power systems. Summary of the Invention

[0004] The purpose of this invention is to provide an aviation starter motor with moisture-proof function to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The starter motor includes a starter housing and a cover. A stabilizer is mounted on the starter housing, and an electronic controller is mounted on the starter housing. A winding frame is mounted inside the starter housing, and multiple sets of electromagnetic coils are wound inside the winding frame. A permanent magnet rotor is mounted inside the starter housing, and a permanent magnet and a compensation coil are mounted on the permanent magnet rotor. Each set of electromagnetic coils is electrically connected to the electronic controller via a wire. An extension cylinder is mounted on the cover, and the cover and the starter housing are fixedly connected by screws. The extension cylinder and the cover are an integral, interconnected structure. A sealing disc is mounted inside the extension cylinder, and a moisture-proof disc is mounted on the permanent magnet rotor. The moisture-proof disc and the sealing disc are in sliding contact. An oil injection hole is provided on the extension cylinder, and a lubrication tank is mounted on the stabilizer. The lubrication tank is connected to the oil injection hole via a conduit. A compensation zone is provided inside the extension cylinder, and a surge component is provided within the compensation zone. Multiple obstacle detection cavities are provided inside the starter housing, and obstacle detection components are installed within the obstacle detection cavities. The obstacle detection components are connected to... The starter motor is electrically connected to the electronic controller via wires. When the starter motor is running, it first supplies power to the electronic controller, which then supplies power to the electromagnetic coil inside the starter housing. The electromagnetic coil generates a magnetic field after being energized, which interacts with the magnetic force on the permanent magnet rotor. The permanent magnet rotor rotates under the influence of the magnetic force, driving the moisture-proof tray above it to rotate as well. The moisture-proof tray and the sealing tray work together to effectively block external moisture and air. At the same time, to overcome resistance, power is also supplied to the compensation coil, causing it to generate magnetic force, thereby increasing the magnetic force and improving the starting effect. During operation, the surge components in the compensation zone work to provide sufficient power for starting, while the obstacle detection components in the obstacle detection cavity work to detect and compensate for the motor during operation, improving the stability of the starter motor. The starter motor usually runs at a high speed, at which point the lubrication tank needs to be activated to provide lubrication for the starter motor's operation.

[0006] A compensation end cover is provided at the end of the starter housing away from the encapsulation cover. An energized screw cover is rotatably connected to the compensation end cover. The energized screw cover is electrically connected to the electrodes of the compensation coil on the permanent magnet rotor. The energized screw cover is also electrically connected to the electronic controller. A torque ring is also provided on the compensation end cover. A trigger plate is provided on the permanent magnet rotor. The trigger plate is in sliding contact with the torque ring. The torque ring is electrically connected to the electronic controller. When the starter motor faces a large load or starts at low speed, the compensation coil needs to work. At this time, the energized screw cover is powered, and the energized screw cover will transmit power to the compensation coil. The contact of the trigger plate also provides power to the compensation coil on the permanent magnet rotor, so that the compensation coil generates the same magnetic field as the permanent magnet, enhances the magnetic field strength, and thus enhances the torque of the starter motor.

[0007] The sealing disc is a cavity inside the extension tube. Multiple sealing grooves are provided on the sealing disc, and pressure plates are installed within these grooves. Multiple blocking edges are also provided within the sealing disc. A pressure ring is installed on the moisture-proof disc, and it is slidably connected to the sealing disc. A pressure lever is installed on the pressure ring. An air filling hole with a sealing valve is located on the sealing disc. When the permanent magnet rotor rotates, it drives the pressure plate on the moisture-proof disc to rotate, causing the pressure ring to slide within the sealing grooves. The pressure lever on the pressure ring continuously slides within the sealing grooves, continuously compressing and releasing air. With the support of the blocking edges, this increases the sealing performance between the permanent magnet rotor and the extension tube until air pressure balance is achieved. Simultaneously, air can be added to the sealing disc at the air filling hole, thus compensating for the internal air pressure.

[0008] The permanent magnet rotor passes through the compensation zone and is rotatably connected to it. The portion of the permanent magnet rotor located in the compensation zone is equipped with an assist groove. A pressure groove is provided in the compensation zone. The surging component is slidably connected to the pressure groove. The compensation zone is equipped with an oil inlet and an oil outlet. The oil inlet is connected to the pressure groove. When the starter motor starts running, if it encounters a large load or large resistance, hydraulic oil will be introduced into the compensation zone, causing the surging component to rotate. After the surging component rotates, it will discharge the hydraulic oil to the oil outlet and circulate it for reuse.

[0009] The surge assembly includes a squeezing wheel and a sensor. The squeezing wheel is rotatably connected to the compensation zone. Multiple oil-blocking grooves are provided on the squeezing wheel. A stop block is rotatably connected to the inner ring of the squeezing wheel via a spring shaft. The stop block slides in contact with the corresponding assist groove. Circulation pipes are provided on the oil inlet and outlet, and these circulation pipes are connected to the sensor. The sensor is mounted on the starting housing. When hydraulic oil enters the compensation zone from the inlet, it accumulates and is squeezed onto the oil-blocking grooves, causing the squeezing wheel to rotate. The rotation of the squeezing wheel moves the internal stop block, squeezing it onto the assist groove, thus causing the permanent magnet rotor to rotate. After rotating to the outlet, as the pressure is released, the hydraulic oil enters the circulation pipe and awaits the next compensation pressurization. Whether surge compensation is required depends on the control of the sensor, which determines whether surge compensation is needed by monitoring the power of the electronic controller.

[0010] The sensing element includes a DC converter and an electromagnetic generator, which are electrically connected. The DC converter is electrically connected to the electronic controller via a wire. The circulation pipe includes a pressure cylinder and an oil injection pipe. The electromagnetic generator is located inside the pressure cylinder, which also contains a reverse magnetic piston. A return spring is located on the side of the reverse magnetic piston away from the electromagnetic generator. A speed sensor is located inside the extension cylinder and is inductively connected to the DC converter. The DC converter monitors the current of the electronic controller and, through the speed measurement by the speed sensor, determines the rotational resistance of the starter motor. After sensing, the DC converter supplies power to the electromagnetic generator. The electromagnetic generator generates magnetic force, causing the reverse magnetic piston to move away from the electromagnetic generator, thereby squeezing the hydraulic oil in the pressure cylinder into the circulation pipe. The hydraulic oil in the circulation pipe, after being squeezed, enters the compensation zone, thereby pressurizing the permanent magnet rotor and achieving a power compensation effect for the permanent magnet rotor during start-up.

[0011] The obstacle detection component includes a detection harness with multiple temperature-sensing resistors. Each temperature-sensing resistor is electrically connected to the detection harness. The detection harness passes through the obstacle detection cavity, and multiple resistor mounting positions are set in the detection slots. Each temperature-sensing resistor is connected to its corresponding mounting position. During the operation of the starter motor, if the electromagnetic coil or capacitor malfunctions, heat will inevitably be generated. At this time, the temperature-sensing resistors on the detection harness will undergo structural changes, indicating that the component at the current location has malfunctioned. Timely feedback is required, and it is necessary to select whether magnetic compensation is needed.

[0012] The obstacle detection component also includes a compensating magnet, which consists of a magnetic frame and a magnetic generating disk. The magnetic frame is connected to the starter housing and is equipped with a magnetic shield. The magnetic generating disk is electrically connected to the electronic controller. A temperature sensing resistor is electrically connected to the electronic controller through a detection harness. When a magnetic compensation signal is received, the electronic controller supplies power to the magnetic generating disk on the magnetic frame, enabling the magnetic generating disk to operate. It can also select a portion of the magnetic generating disk to generate magnetic force, thereby providing magnetic force for the rotation of the permanent magnet rotor to avoid problems such as unstable speed or inability to rotate, providing double protection for the rotation of the starter motor.

[0013] The lubrication tank contains lubricating oil and is equipped with an oil supply pump. The output end of the oil supply pump is connected to the oil filling hole through a conduit. The lubrication tank has a return port with a return wheel inside. The blades of the return wheel are fitted with filter screens that slide in contact with the return port. After the motor starts running, if the internal components do not receive sufficient lubrication, wear will inevitably occur. At this time, the oil supply pump is activated to supply and replace lubricating oil to the bearing components inside the starter motor, thereby maintaining the condition of the bearing components and improving the service life of the equipment. The filter screen is also used to screen out impurities in the lubricating oil, ensuring the performance of the lubricating oil.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention employs a power component with a compensation coil, which broadens the applicability of the device and provides assistance in overcoming the magnetic force of huge resistance. By utilizing the magnetic force of the compensation coil, the torque of the device can be increased in a short or long time, thereby improving the stability of the power output.

[0016] 2. This invention employs a compensating structural component to help the starter motor overcome the problem of high inertia during startup, and performs automatic monitoring and analysis. This reduces the problem of insufficient magnetic force during equipment operation, reduces the failure rate of electromagnetic coils, improves the immediacy of the equipment, and speeds up the response speed to commands.

[0017] 3. The present invention also adopts a structural component with automatic fault location analysis. By analyzing the heat of the equipment during operation, the fault location of the starter motor can be fully determined, and targeted magnetization or continuous magnetic force supply can be carried out to ensure the stability of the rotation speed of the starter motor during operation and avoid unexpected situations.

Each set of electromagnetic coils 6 is electrically connected to the electronic controller 4 through a wire. An extension tube 10 is provided on the cover 2, and there is a communication between the cover 2 and the starter housing 1. The extension tube 10 and the encapsulation cover 2 are integrally connected via screws. A sealing disc 11 is installed inside the extension tube 10. A moisture-proof disc 12 is mounted on the permanent magnet rotor 7, and the moisture-proof disc 12 slides in contact with the sealing disc 11.

Multiple obstacle detection chambers 17 are provided inside the starting housing 1, and each obstacle detection chamber 17 contains... There is a fault detection component 18, which is electrically connected to the electronic controller 4 via wires. When the starter motor is running, it first supplies power to the electronic controller 4, and then the electronic controller 4 supplies power to the electromagnetic coil 6 inside the starter housing 1. After the electromagnetic coil 6 is energized, it generates a magnetic field, which cooperates with the magnetic force on the permanent magnet rotor 7. The permanent magnet rotor 7 rotates under the influence of the magnetic force, and drives the moisture-proof tray 12 above it to rotate. The moisture-proof tray 12 and the sealing tray 11 cooperate with each other to effectively block external moisture and air. At the same time, in order to overcome resistance, it also... Power is supplied to the compensation coil 9, causing it to generate magnetic force, thereby increasing the magnetic force and improving the starting effect. During operation, the surge component 16 in the compensation zone 15 works to provide sufficient power for starting, while the obstacle detection component 18 in the obstacle detection cavity 17 works to detect and compensate for the motor in operation, improving the stability of the starter motor. The starting motor usually operates at a high speed, at which time the lubrication tank 14 needs to be activated to provide lubrication for the operation of the starter motor.

[0030] A compensation end cover 201 is provided at the end of the starter housing 1 away from the encapsulation cover 2. An energized cover 202 is rotatably connected to the compensation end cover 201.

The energized cover 202 is also electrically connected to the electronic controller 4. A torque ring 203 is also provided on the compensation end cover 201. A trigger plate 204 is provided on the permanent magnet rotor 7. The trigger plate 204 is in sliding contact with the torque ring 203. The torque ring 203 is electrically connected to the electronic controller 4. When the starter motor faces a large load or starts at low speed, the compensation coil 9 needs to work. At this time, the energized cover 202 is powered. The energized cover 202 transmits power to the compensation coil 9. The contact of the trigger plate 204 also provides power to the compensation coil 9 on the permanent magnet rotor 7, so that the compensation coil 9 generates the same magnetic field as the permanent magnet 8, which enhances the magnetic field strength and thus enhances the torque of the starter motor.

[0031] The sealing disc 11 is a cavity inside the extension tube 10. Multiple sealing grooves 1101 are provided on the sealing disc 11, and pressure plates 1102 are installed within each sealing groove 1101. Multiple blocking edges 1103 are also provided inside the sealing disc 11. A pressure ring 1201 is provided on the moisture-proof disc 12, and the pressure ring 1201 is slidably connected to the sealing disc 11. A pressure lever 1202 is provided on the pressure ring 1201.

The pressure lever 1202 on the pressure ring 1201 slides continuously in the sealing groove 1101, and the pressure lever 1202 continuously compresses and releases air. With the support of the blocking edge 1103, the sealing performance of the permanent magnet rotor 7 and the extension tube 10 is increased until the air pressure balance is reached. At the same time, the sealing tray 11 at the air filling hole 1104 can be inflated to compensate for the internal air pressure.

[0032] The permanent magnet rotor 7 passes through the compensation zone 15 and is rotatably connected to the compensation zone 15. The portion of the permanent magnet rotor 7 located in the compensation zone 15 is provided with an assist groove 701. The compensation zone 15 is provided with a pressure groove 702. The surging component 16 is slidably connected to the pressure groove 702. The compensation zone 15 is provided with an oil inlet 703 and an oil outlet 704. The oil inlet 703 is connected to the pressure groove 702. When the starter motor starts running, if it encounters a large load or large resistance, hydraulic oil will be introduced into the compensation zone 15, causing the surging component 16 to rotate. After the surging component 16 rotates, it will discharge the hydraulic oil to the oil outlet 704 and circulate it for reuse.

[0033] The surging assembly 16 includes a squeezing roller 1601 and a sensing element. The squeezing roller 1601 is rotatably connected to the compensation zone 15. Multiple oil-blocking grooves 1603 are provided on the squeezing roller 1601. A stop block 1604 is rotatably connected to the inner ring of the squeezing roller 1601 via a spring shaft.

Circulation pipes 1605 are provided on the oil inlet 703 and the oil outlet 704, and the circulation pipes 1605 are connected to the sensing element.

The hydraulic oil will accumulate and be squeezed onto the oil baffle groove 1603, causing the extrusion roller 1601 to rotate. After the extrusion roller 1601 rotates, it will drive the internal stop block 1604 to move and squeeze onto the booster groove 701, thereby causing the permanent magnet rotor 7 to rotate. After rotating to the outlet, as the pressure is released, the hydraulic oil will enter the circulation pipe 1605 and wait for the next compensation pressurization. Whether surge compensation is required depends on the control of the sensor. The sensor determines whether surge compensation is required by monitoring the power of the electronic controller 4.

[0034] The sensing element includes a DC converter 1607 and an electromagnetic generator 1608. The electromagnetic generator 1608 is electrically connected to the DC converter 1607.

The electromagnetic generator 1608 is disposed inside the pressure cylinder 1609. A reverse magnetic piston 1611 is also disposed inside the pressure cylinder 1609. A return spring 1612 is disposed on the side of the reverse magnetic piston 1611 away from the electromagnetic generator 1608. A speed sensor 1613 is disposed inside the extension cylinder 10. The speed sensor 1613 is inductively connected to the DC converter 1607. DC converter 1607 monitors the current of electronic controller 4 and measures the speed through speed sensor 1613 to determine the rotational resistance of the starter motor. After sensing, DC converter 1607 supplies power to electromagnetic generator 1608. After the electromagnetic generator 1608 generates magnetic force, the reverse magnetic piston 1611 will move away from the electromagnetic generator 1608, thereby squeezing the hydraulic oil in pressurizing cylinder 1609 into circulation pipe 1605. The hydraulic oil in circulation pipe 1605 enters compensation zone 15 after being squeezed, thereby pressurizing permanent magnet rotor 7 and realizing the power compensation effect of permanent magnet rotor 7 during start-up.

[0035] The obstacle detection component 18 includes a detection harness 1801, on which multiple temperature-sensing resistors 1802 are installed. Each temperature-sensing resistor 1802 is electrically connected to the detection harness 1801. The detection harness 1801 passes through the obstacle detection cavity 17. Multiple resistor mounting positions 1803 are provided in the detection slot. Each temperature-sensing resistor 1802 is connected to the corresponding resistor mounting position 1803. During the operation of the starter motor, if the electromagnetic coil 6 and capacitor malfunction, heat will inevitably be generated. At this time, the temperature-sensing resistors 1802 on the detection harness 1801 will undergo tissue changes, thus indicating that the component at the current position has malfunctioned. Timely feedback is required, and it is necessary to select whether magnetic compensation is needed.

[0036] The obstacle detection component 18 also includes a compensating magnet 1804, which includes a magnetic frame 1805 and a magnetic generating disk. The magnetic frame 1805 is connected to the starter housing 1, and a magnetic shield is provided on the magnetic frame 1805. The magnetic generating disk is electrically connected to the electronic controller 4. The temperature sensing resistor 1802 is electrically connected to the electronic controller 4 through the detection harness 1801. When a magnetic compensation signal is received, the electronic controller 4 supplies power to the magnetic generating disk on the magnetic frame 1805, so that the magnetic generating disk can work. It can also select a part of the magnetic generating disk to generate magnetic force, thereby providing magnetic force for the rotation of the permanent magnet rotor 7, so as to avoid the problem of unstable speed or failure to rotate, and provide double insurance for the rotation of the starter motor.

[0037] The lubrication tank 14 contains lubricating oil and is equipped with an oil supply pump 1401. The output end of the oil supply pump 1401 is connected to the oil injection hole 13 through a conduit. The lubrication tank 14 is equipped with a return port 1402, and a return wheel 1403 is installed in the return port 1402. A filter screen 1404 is installed on the blades of the return wheel 1403. The filter screen 1404 slides in contact with the return port 1402. After the motor starts running, if the internal components do not receive sufficient lubrication, wear will inevitably occur. At this time, the oil supply pump 1401 is started to supply and replace the lubricating oil for the bearing assembly in the starter motor, thereby maintaining the service condition of the bearing assembly and improving the service life of the equipment. The filter screen 1404 is used to screen out impurities in the lubricating oil to ensure the performance of the lubricating oil.

[0038] Working principle: Power is supplied to the electronic controller 4, which then supplies power to the electromagnetic coil 6 inside the starting housing 1. The electromagnetic coil 6 generates a magnetic field, which interacts with the magnetic force on the permanent magnet rotor 7. The permanent magnet rotor 7 rotates under the influence of the magnetic force, causing the moisture-proof tray 12 above it to rotate as well. The moisture-proof tray 12 cooperates with the sealing tray 11, and the pressure ring 1201 slides within the sealing groove 1101. The pressure-pressurizing paddle 1202 on the pressure ring 1201 continuously slides within the sealing groove 1101, continuously compressing and releasing air to achieve an air seal effect. Simultaneously, to overcome resistance, power is supplied to the compensation coil 9, causing it to generate magnetic force, thereby increasing the torque of the starting motor. During operation, the surging component 16 within the compensation zone 15 operates. If a large load or significant resistance is encountered, at this time... Hydraulic oil will be introduced into the compensation zone 15, causing the extrusion wheel 1601 to rotate. After the extrusion wheel 1601 rotates, it will drive the internal stop block 1604 to move and press against the assist groove 701, thereby causing the permanent magnet rotor 7 to rotate. The obstacle detection component 18 in the obstacle detection cavity 17 will work, and the temperature sensing resistor 1802 on the detection harness 1801 will produce tissue changes, thereby indicating that the component at the current position has failed. The motor in operation will be detected in time and compensated. When the magnetic compensation signal is received, the controller 4 will supply power to the magnetic force generating disk on the magnetic force frame 1805, so that the magnetic force generating disk will work and improve the stability of the starter motor. The starting motor usually runs at a high speed. At this time, the lubrication tank 14 needs to be started and the oil supply pump 1401 needs to be started to supply and replace the lubricating oil for the bearing components in the starter motor.
