Description
Technical Field
[0001] The invention relates to the technical field of air-conditioning motors, and in particular to an air-conditioning composite motor which can be adjusted according to an installation position. Background Art
[0002] The air conditioner motor is the power source of the fan. It drives the fan to rotate and circulate the indoor air. This process not only helps to remove damp and dirty air, but also keeps the indoor air clean and comfortable. The operation of the fan can enhance convection, thereby improving the heat exchange efficiency of the air conditioner. In cooling mode, cold air is delivered into the room faster; in heating mode, hot air can also be more effectively distributed to every corner of the room.
[0003] The motor needs to be adapted to the air conditioner, installed in the air conditioner, and drive the impeller to rotate. The motor is generally fixed inside the air conditioner through a fixing. The output end of the motor needs to be connected to the impeller, so that the axis of the motor output end must coincide with the axis of the impeller to achieve accurate installation. In different air conditioners, the same motor needs to be connected with different fixings. In addition, during the use of the motor, a certain vibration will be generated. This vibration is a normal phenomenon when the motor is working, but the vibration amplitude should be controlled within a reasonable range to ensure the stable operation of the motor and reduce the negative impact on other components of the air conditioning system. The magnitude of the vibration is affected by many factors, including the design, manufacturing quality, installation accuracy, load conditions, etc. of the motor. If the motor vibrates too much, it may be caused by internal motor failure, improper installation, load imbalance, or system resonance. Excessive vibration will not only affect the service life of the motor, but may also cause damage to other components of the air conditioning system, such as bearing wear, loose connectors, and increased noise.

DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0031] See also Figure 1-Figure 7 The present invention provides a technical solution: The vibration of the motor in the air conditioner may bring a series of disadvantages, which not only affect the performance and life of the air conditioning system, but also may have an adverse effect on the surrounding environment and human health. The noise generated by the vibration of the air conditioner motor will be transmitted to the surrounding environment through the building structure, causing noise pollution to neighbors and the surrounding environment. In some cases, the vibration frequency of the air conditioner motor may be close to the natural frequency of the building structure, resulting in the occurrence of resonance, further aggravating the impact of noise and vibration. For this reason, it is proposed as follows Figure 1 The composite motor of an air conditioner which can be adjusted according to the installation position shown in the figure comprises a motor body 1 and an output shaft 2 connected to the output end of the motor body 1, wherein the motor body 1 drives the output shaft 2 to rotate, realizes the transmission of power, and drives the impeller in the air conditioner to rotate. A vibration-damping frame 3 for supporting the motor body 1 is arranged on the outside of the motor body 1. The vibration-damping frame 3 comprises a support sleeve 34 fixed on the outside of the motor body 1, the axis of the support sleeve 34 coincides with the axis of the output shaft 2, and the two are sleeved. A vibration-damping layer 37 for vibration reduction is fixed on the outside of the support sleeve 34. Through the vibration-damping frame 3, during the operation of the motor body 1, the motor body 1 will generate vibrations during operation. If these vibrations are directly transmitted to the supporting structure or the surrounding environment, they may cause problems such as structural damage and increased noise. The vibration-damping frame 3 absorbs and disperses these vibration energies through its internal elastic elements, thereby effectively reducing the transmission of vibrations.
[0032] In some cases, the vibration frequency of the motor body 1 may be close to the natural frequency of the supporting structure, thereby causing resonance. The design of the vibration-damping frame 3 can adjust its stiffness and damping characteristics to avoid or reduce the occurrence of such resonance and protect the safety of the motor body 1 and the supporting structure.
[0033] The end of the output shaft 2 is provided with two connecting parts 4, and the ends of the two connecting parts 4 that are close to each other are respectively connected with the shaft 1 5 and the shaft 2 6 that cooperate with each other. The shaft 1 5 and the shaft 2 6 can be telescopically arranged, and the outer sides of the two connecting parts 4 are respectively fixed to the output shaft 2 and the impeller, and the transmission direction of the connecting part 4 can be changed at multiple angles. The connecting part 4 can realize the transmission between the output shaft 2 of the motor and the load at different angles. When the axis of the motor and the load are not completely parallel, or there is an angle change, the connecting part 4 can flexibly adapt to these changes to ensure the continuity and stability of the transmission. The motor body 1 will generate vibrations during operation. If these vibrations are directly transmitted to the load, they may cause damage to the load or affect the stability of the transmission. The connecting part 4 connected to the output shaft 2 of the motor body 1 can absorb and disperse these vibration energies to a certain extent, thereby playing a role in vibration reduction. Vibration is one of the main sources of noise. By reducing the transmission of vibration, the connecting part 4 also helps to reduce the noise level of the transmission system and improve the overall working environment and user experience. In addition, it can be telescopically arranged, and the absorption and dispersion capacity of vibration can be further increased. When the motor body 1 generates vibration, the shaft 1 5 and the shaft 2 6 can expand and contract to absorb the vibration energy, reduce the impact of the vibration on the transmission system, and control the transmission of the vibration.
[0034] like Figure 2 and Figure 3 As shown, the vibration damping frame 3 is used to fix the motor body 1 in the air conditioner. The vibration damping frame 3 also includes a rectangular frame 31 with a hollow interior. The rectangular frame 31 is laterally penetrated by a circular hole 32 coaxially arranged with the output shaft 2. An inner circular layer 33 coaxially arranged with the circular hole 32 is fixed inside the rectangular frame 31. The output shaft 2 and the support sleeve 34 pass through the circular hole 32 and the inner circular layer 33. The vibration damping layer 37 is fixed in the inner circular layer 33. The motor body 1 is supported by the support sleeve 34. In addition, the support sleeve 34 is also supported by the vibration damping layer 37, so that the vibration damping layer 37 absorbs and blocks the vibration. Even if the motor body 1 vibrates, it will not be transmitted through the vibration damping frame 3, thereby avoiding vibration of the air conditioner.
[0035] In addition, the vibration-damping layer 37 circumferentially covers the support sleeve 34 and fixes the motor body 1 in the circumferential direction to make the motor body 1 firm. In addition, the motor body 1 is prevented from directly contacting the supporting components or the air conditioner through the vibration-damping layer 37 .
[0036] A circular extension piece 2 36 is fixed on the inner wall of the inner circle layer 33, and a circle of extension piece 1 35 is fixed on the outer wall of the support sleeve 34. The extension piece 1 35 and the extension piece 2 36 are abutted against each other, and a vibration-damping layer 37 is provided on the outward side of the extension piece 1 35 and the extension piece 2 36. When the motor body 1 is working, vibration is often generated in the rotation direction rather than the axial direction. Therefore, the motor body 1 is limited by the extension piece 1 35 and the extension piece 2 36. The axial direction is limited and the transmission of vibration will not be caused.
[0037] The vibration reduction layer 37 is a rubber ring, which can effectively absorb the vibration energy generated by the motor or mechanical equipment during operation by utilizing its good elasticity and damping properties. This absorption effect can significantly reduce the impact of vibration on the equipment itself and its surrounding environment.
[0038] like Figure 4 and Figure 6 As shown, the connection part 4 includes two intersecting C-shaped frames 41, a cross 46 is supported inside the two C-shaped frames 41, and a connecting hole 42 is penetrated through the outer side of the C-shaped frame 41. The four axial ends of the cross 46 are respectively clamped into the four connecting holes 42. The two C-shaped frames 41 are hinged through the cross 46 to achieve a universal joint effect;
[0039] The two connecting parts 4 make the axis of the output shaft 2 not coaxial with the axis of the impeller.
[0040] The C-shaped frames 41 close to each other in the two connecting parts 4 are respectively fixed to the ends of the shaft 1 5 and the shaft 2 6, and the C-shaped frames 41 far away from each other are respectively fixed to the output shaft 2 and the impeller;
[0041] like Figure 5 As shown, the inner end of shaft one 5 is integrally formed with a polygonal shaft 51, and the inner end of shaft two 6 is provided with a polygonal hole 61 extending along its axis. The polygonal hole 61 cooperates with the polygonal shaft 51 and can be telescopically arranged for vibration reduction. The polygonal hole 61 cooperates with the polygonal shaft 51 so that the rotational action can be transmitted.
[0042] like Figure 6 and Figure 7 As shown, support sheets 47 are fixed on the axes of the four directions of the cross 46, and the support sheets 47 abut against the inner wall of the C-shaped frame 41 to achieve the supporting function, and the cross 46 and the C-shaped frame 41 are kept stable;
[0043] An outer pressure plate 43 is fixed to the outer side of the C-shaped frame 41, and the axis of the outer pressure plate 43 coincides with the axis of the connecting hole 42. The inner part of the outer pressure plate 43 also has a circular cavity 44 connected to the connecting hole 42. The outer side of the circular cavity 44 is covered with an end cover 45, and the inner part of the circular cavity 44 is filled with lubricating oil for lubrication. It should be noted that during the rotation of the connecting part 4, the part of the cross 46 inserted into the connecting hole 42 is always immersed in the lubricating oil and always keeps lubricated. The lubricating oil is squeezed out of the outer pressure plate 43 by the support sheet 47, and the lubricating oil is limited. Even if the lubricating oil is reduced, the end cover 45 can be opened to add it.
[0044] The C-shaped frame 41 and the cross 46 are made of plastic material to minimize weight. Compared with materials such as metal, plastic material has lighter weight and better wear resistance. At the same time, the price of plastic material is relatively low, which helps to reduce production costs and make the product more economical.
[0045] The working principle of the present invention is: the output end of the motor body 1 is used to work, and the impeller is driven to work through two connecting parts 4, shaft one 5 and shaft two 6. The main function of the impeller is to realize the cooling, heating, dehumidification and other functions of the air conditioner by driving the air circulation. When the motor body 1 is installed in different types of air conditioners, the same vibration reduction frame 3 is used to connect the motor body 1 and the air conditioner, then the output shaft 2 of the motor body 1 will be difficult to be coaxial with the impeller, and the connection part 4 is equivalent to a universal joint. Even if the output shaft 2 is not coaxial with the impeller, the power transmission between the two can be realized, which is convenient for installation in different air conditioners.
[0046] In addition, in order to reduce the vibration amplitude of the motor, the motor body 1 is supported by the support sleeve 34 and the vibration-damping layer 37 at the outer end of the motor body 1. Even if the motor body 1 vibrates during operation, it can be absorbed by the vibration-damping layer 37. The rubber material, due to its good elasticity and damping properties, can effectively absorb the vibration energy generated by the motor body 1 during operation, thereby reducing the transmission and diffusion of vibration. This vibration-damping effect helps to reduce the mechanical noise of the motor and improve the quietness of the overall working environment. By isolating the motor from the surrounding structure, the rubber vibration-damping layer 37 can block the propagation path of vibration from the motor to other components or structures, thereby further reducing the impact of vibration and noise on equipment and personnel.
[0047] In addition, by providing a telescopic effect between the shaft 1 5 and the shaft 2 6, and the cooperation between the polygonal shaft 51 and the polygonal hole 61, when the motor body 1 generates vibration, the output shaft 2 transmits the vibration, and when passing through the shaft 1 5 and the shaft 2 6, the shaft 1 5 and the shaft 2 6 are telescopic and the connection part 4 is transmitted. When there is an angle deviation or change between the output shaft 2 of the motor and the load, the connection part 4 can absorb these deviations, reduce the vibration and impact caused by the mismatch of the angle, and ensure the smooth transition of the angle change and the constant speed transmission. The telescopic setting allows a certain adjustment space between the connecting parts in the length direction, which can adapt to the small displacement or length change that may occur in the motor body 1 during operation, and can further improve the vibration reduction effect of the motor drive system. The double connection part 4 ensures the smooth transition of the angle change and the constant speed transmission, and the telescopic setting adapts to the change in the length direction. The combined effect of the two can significantly reduce the vibration and noise level of the motor during operation, and improve the stability and reliability of the system.
