Description

Technical Field

[0001] This invention relates to the field of brake cooling technology, specifically to a novel split-type irregularly shaped cooling motor. Background Technology

[0002] When an aircraft equipped with wheel brakes lands, the braking action generates a significant amount of heat. It requires the brakes to cool down to a temperature suitable for takeoff before it can take off again. However, the cooling time for wheel brakes is often lengthy. Without a brake cooling system, this would increase the aircraft's turnaround time. Furthermore, during takeoff and landing taxiing, multiple applications of the brakes can also cause them to overheat, preventing them from reaching takeoff conditions. Current aircraft brake cooling methods rely on ground-based auxiliary equipment, such as air-conditioned vehicles. If some airports lack these vehicles, the aircraft's turnaround time will be prolonged, significantly reducing operational efficiency.

[0003] The existing three-phase asynchronous motor structure includes a socket; a motor rear cover assembly; a housing rear cover assembly; a disc spring; a first bearing; a second bearing; a housing assembly; a rotor assembly; and a front cover assembly. This three-phase asynchronous motor structure can meet the requirements for a motor used for cooling and driving wheel brakes. However, the brake cooling motor is installed inside the main landing gear axle, where the impact and vibration generated during landing gear and wheel brake operation are directly transmitted to the motor. Furthermore, the motor operates under high-level impact and vibration conditions for extended periods. This design does not consider the impact and vibration environment and lacks an effective buffer and vibration reduction structure between the housing and the axle. Long-term operation may cause structural damage to the motor. On the other hand, the motor housing is a conventional motor housing, requiring additional adapters to enclose the motor when it mates with the axle, which degrades the motor's heat dissipation.

[0004] Therefore, a novel split-type irregularly shaped cooling motor is needed to solve the above problems. Summary of the Invention

[0005] In view of the problems that existing technologies do not consider the impact and vibration environment, and do not have an effective buffer and vibration reduction structure between the housing and the axle, which may cause damage to the motor structure during long-term operation, and that the motor housing is a conventional motor housing, which requires an additional adapter to wrap the motor when it is used with the axle, resulting in poor heat dissipation of the motor itself, this invention provides a novel split-type irregular cooling motor to solve the existing problems.

[0006] The first aspect of this invention provides a novel split-type irregularly shaped cooling motor, employing the following technical solution, including: The housing and adapter are coaxially connected, and both the housing and adapter are equipped with weight-reducing and heat-dissipating structures. The adapter is used to mate with the mounting cavity of the wheel axle. The diameter of the housing is smaller than the diameter of the adapter. The stator assembly is fitted and fixed inside the housing; The rotor assembly is coaxially disposed within the stator assembly and is rotatably connected to the housing and the adapter respectively. The output end of the rotor assembly extends into the adapter. The elastic support assembly is used to support the inner wall of the mounting cavity for the motor tail end and the wheel axle; And a socket, which is located on the housing opposite to the adapter, and the socket is electrically connected to the stator winding in the stator assembly.

[0007] A further technical solution of the present invention is that the housing includes: a front housing and a rear housing coaxially connected, the end of the front housing opposite to the rear housing is coaxially connected to the adapter, and the end of the rear housing opposite to the front housing is connected to a bracket, wherein the socket is disposed on the bracket and the weight reduction and heat dissipation structure is disposed on the rear housing.

[0008] A further technical solution of the present invention is that the weight-reducing heat dissipation structure includes multiple weight-reducing heat dissipation slots, which are evenly distributed on the rear housing and the adapter.

[0009] A further technical solution of the present invention is that the rotor assembly includes a rotor shaft, the tail of which is mounted to the connection between the front end housing and the rear end housing via a rear end bearing; the front of the rotor shaft is mounted to the connection between the front end housing and the adapter via a front end bearing.

[0010] A further technical solution of the present invention is that the elastic support assembly includes: a plurality of support seats, which are evenly distributed on the outer periphery of the rear end housing near the front end housing, a support rubber is provided on the end of the support seat away from the rear end housing, a support pad is provided on the support rubber, and the support pad is used to contact the inner wall of the mounting cavity of the wheel axle.

[0011] A further technical solution of the present invention is that the support base is made of high-strength stainless steel; the support rubber is made of high and low temperature resistant silicone rubber; and the support pad is made of polytetrafluoroethylene.

[0012] A further technical solution of the present invention is that the socket is connected to a cable, and the cable enters the front end of the front end housing and is electrically connected to the stator winding.

[0013] A further technical solution of the present invention is that an axial mounting groove is provided at the connection between the front housing and the adapter, the axial mounting groove is used to install the front bearing, and an adjustment washer is provided between the front bearing and the groove wall of the axial mounting groove.

[0014] The beneficial effects of this invention are: 1. In contrast to the existing "motor body + external adapter" approach for cooling motors, the adapter and housing of the cooling motor of this invention have an irregular structure, serving as both the outer shell of the motor body and the external adapter. This adapts to the installation space while providing support for the stator and rotor assemblies, effectively reducing the motor's weight. Simultaneously, an elastic support assembly is provided between the cooling motor housing and the axle to absorb the impact and vibration generated during the operation of the landing gear and wheel brakes. Furthermore, this cooling motor can be installed into the axle without requiring additional adapters, reducing the overall weight of the equipment within the axle. Since the diameter of the motor housing is smaller than the adapter diameter, there is a larger heat dissipation gap between the motor housing and the axle mounting cavity when the axle and adapter are installed together. Combined with the weight-reducing heat dissipation grooves on the housing and adapter, the motor's own heat dissipation effect is further improved.

[0015] 2. The cooling motor of the present invention is equipped with an adjusting washer, which can prevent bearing jamming due to heat by adjusting the gap between the front bearing and the adapter, and also has the function of reducing noise; secondly, since the housing of the cooling motor is of the split type, it is convenient to install and disassemble, the operation is simple, and the maintenance cycle can be effectively shortened.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] An embodiment of a novel split-type irregularly shaped cooling motor according to the present invention, such as... Figure 1 and 2 As shown, it includes: adapter 1, housing 2, stator assembly 4, rotor assembly 5, elastic support assembly 8, and socket 11; housing 2 and adapter 1 are coaxially connected, the diameter of housing 2 is smaller than the diameter of adapter 1, and both housing 2 and adapter 1 are provided with weight reduction and heat dissipation structures. Adapter 1 is used to cooperate with the mounting cavity of the wheel axle; stator assembly 4 is fitted and fixed inside housing 2; rotor assembly 5 is coaxially disposed inside stator assembly 4, and rotor assembly 5 is rotatably connected to the inside of housing 2 and adapter 1 respectively, and the output end of rotor assembly 5 extends into adapter 1; elastic support assembly 8 is disposed between the tail end of housing 2 and the inner wall of the mounting cavity of wheel axle, and is used to support the inner wall of the mounting cavity of housing 2 and wheel axle; socket 11 is disposed on the side of housing 2 away from adapter 1, and socket 11 is electrically connected to the stator winding in stator assembly 4. It should be noted that the stator assembly 4 is installed inside the housing 2, and an interference fit is used to prevent the stator assembly 4 from rotating or moving axially inside the housing 2; the rotor assembly 5 is installed inside the stator assembly 4, with a small air gap between it and the stator assembly 4, which ensures that the rotor assembly 5 can rotate at high speed while effectively reducing electromagnetic losses.

[0027] For example, such as Figure 7 As shown, in one specific embodiment, the housing 2 includes: a front housing and a rear housing coaxially connected, wherein the end of the front housing opposite to the rear housing is coaxially connected to the adapter 1, as shown. Figure 2 and Figure 6As shown, the end of the rear housing opposite to the front housing is connected to a bracket 9 by screws. The bracket 9 is made of stainless steel and features a lightweight groove while ensuring structural strength. The bracket 9 has a reserved mounting interface for an electrical connector, which is used to install a motor socket. The socket 11 is located on the mounting interface of the bracket 9. The weight-reducing and heat-dissipating structure is located on the rear housing. Figure 3 As shown, in this embodiment, the adapter 1 and the front end housing of the housing 2 are connected by screws. The adapter 1 and the housing 2 together constitute the outer shell of the irregularly shaped cooling motor. The adapter 1 can be adapted to the internal structure of the wheel axle. The adapter 1 is made of stainless steel, which can ensure the structural strength of the cooling motor. The weight-reducing heat dissipation structure includes multiple weight-reducing heat dissipation slots, which are evenly distributed on the rear end housing and the adapter 1. The housing 2 is made of high-strength aluminum alloy. Due to the setting of the weight-reducing heat dissipation slots, the strength of the housing 2 can be ensured while the weight of the cooling motor can be reduced.

[0028] For example, in one specific embodiment, the weight-reducing heat dissipation structure includes a plurality of weight-reducing heat dissipation slots, which are evenly distributed on the rear housing and the adapter 1.

[0029] For example, in one specific embodiment, the rotor assembly 5 includes a rotor shaft, the tail of which is mounted to the connection between the front and rear housings via a rear bearing 7; the front of the rotor shaft is mounted to the connection between the front housing and the adapter 1 via a front bearing 6; wherein, in this embodiment, both the front bearing 6 and the rear bearing 7 are sealed bearings, effectively preventing foreign objects from entering the interior of the stator assembly 4 and causing damage to the motor.

[0030] For example, such as Figure 2 , Figure 3 and Figure 5 As shown, in one specific embodiment, the elastic support assembly 8 includes: multiple support seats 8-1, which are evenly distributed on the outer periphery of the rear end housing near the front end of the front end housing. Supporting rubber 8-2 is provided on the end of each support seat 8-1 facing away from the rear end housing, and a supporting pad 8-3 is provided on the supporting rubber 8-2. The supporting pad 8-3 is used to contact the inner wall of the mounting cavity of the wheel axle. The elastic support assembly 8 is used to effectively prevent structural damage caused by excessive amplitude at the tail end in a vibrating environment. In this embodiment, three protrusions are reserved on the outer periphery of the rear end housing of the housing 2. Support seats 8-1 are installed on the protrusions. The support seats 8-1 are made of high-strength stainless steel with an external hexagonal structure for easy installation and disassembly. The supporting rubber 8-2 is made of high- and low-temperature resistant silicone rubber, bonded to the support seats 8-1 through a vulcanization process, serving as a buffer and vibration damping agent. The supporting pad 8-3 is made of polytetrafluoroethylene (PTFE) to facilitate the installation of a cooling motor inside the wheel axle.

[0031] For example, in one specific embodiment, the socket 11 is connected to a cable 10, which enters the front end housing from the front end of the front end housing and is electrically connected to the stator winding.

[0032] For example, such as Figure 3 and Figure 4 As shown, in one specific embodiment, an axial mounting groove is provided at the connection between the front housing and the adapter 1. The axial mounting groove is used to install the front bearing 6, and an adjusting washer 3 is provided between the front bearing 6 and the groove wall of the axial mounting groove. The gap between the front bearing 6 and the adapter 1 is adjusted by the adjusting washer 3, so that there is still room for movement after the front bearing 6 is heated and expanded, thus preventing the front bearing 6 from getting stuck.

[0033] Working principle This invention discloses a novel split-type irregularly shaped cooling motor, which adopts a split and irregularly shaped shell structure, breaking away from the conventional design of cooling motors and greatly reducing the overall weight. After the novel split-type irregularly shaped cooling motor is connected to power via socket 11, the stator assembly 4 is energized to form a rotating magnetic field, which drives the rotor assembly 5 to rotate under the principle of electromagnetic induction. The cooling motor works in conjunction with a fan to provide braking and cooling. This novel split-type irregularly shaped cooling motor has a support pin 8 at the rear end for support, preventing excessive cantilever at the rear end of the motor.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
