Description

Technical Field

[0001] The present invention relates to the field of household electrical appliances, and in particular to a bearing assembly and air conditioning equipment. Background Art

[0002] Air conditioning equipment can be used to adjust the temperature and humidity of the surrounding air. For example, an air conditioner is equipped with a wind wheel, which can blow out cold air when the wind wheel rotates. Due to processing tolerances and dynamic balance, the wind wheel is prone to vibration, which generates noise and affects the user experience. Traditional air conditioners usually have a rubber ring and a rotating shaft of the wind wheel, and use the elastic deformation of the rubber ring to absorb the vibration of the wind wheel, thereby improving the problem of excessive noise. However, if the elastic deformation of the rubber ring is too large, the positioning accuracy of the wind wheel will be reduced. For this reason, the elastic deformation of the rubber ring is designed to be smaller, but the noise reduction effect is not obvious. Summary of the invention

[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0037] In the description of the present invention, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] The air conditioning equipment can be used to adjust the temperature, humidity, etc. of the surrounding air. For example, the air conditioning equipment can be an air conditioner 1000, a humidifier, an air purifier, etc. Taking the air conditioner 1000 as an example, refer to Figure 1 As shown, an air conditioner 1000 according to an embodiment of the present invention comprises a housing 200, a wind wheel 300 and a motor 220. The housing 200 is provided with a receiving chamber 210, and the wind wheel 300 is installed in the receiving chamber 210. The motor 220 is used to drive the wind wheel 300 to rotate, so as to blow out the cold air. The wind wheel 300 can be a crossflow wind wheel or a centrifugal wind wheel. The motor 220 is driven and connected to one end of the wind wheel 300, and the other end of the wind wheel 300 is connected to a bearing. Due to the processing tolerance and dynamic balance of the wind wheel 300, the wind wheel 300 will vibrate, so a rubber ring can be set to absorb the vibration and reduce the noise. However, due to the large elastic deformation of the rubber ring, the positioning accuracy of the wind wheel 300 will be reduced, and the wind wheel 300 is prone to yaw and misalignment. Therefore, the elastic deformation of the rubber ring is small, resulting in an insignificant noise reduction effect.

[0040] In order to further reduce the noise of the wind wheel 300 during operation, refer to Figure 2 , Figure 3 and Figure 4 As shown, a bearing assembly 100 according to an embodiment of the present invention comprises a bearing ring 120 and a plurality of rolling bodies 130. The bearing ring 120 comprises a plurality of ring segments 121. The ring segments 121 are elastic, and the flexibility of at least two of the plurality of ring segments 121 is different. The plurality of ring segments 121 may be sequentially connected along the axial direction of the bearing ring 120, or may be arranged independently of each other. A first mounting cavity 122 is formed in at least two of the ring segments 121, respectively, and the plurality of rolling bodies 130 are correspondingly arranged in the plurality of first mounting cavities 122. The rolling body 130 is provided with a mounting hole 133, which is arranged through the axis of the bearing ring 120. The rotating shaft 310 of the wind wheel 300 is arranged in the mounting hole 133 and is fixedly connected to the rolling body 130. Therefore, when the rotating shaft 310 rotates, the rolling body 130 is driven to rotate synchronously. The cooperation between the rolling body 130 and the first mounting cavity 122 can reduce the friction force when the wind wheel 300 rotates. For example, the number of the ring segments 121 may be two, three or four, and the number of the rolling bodies 130 may be two, three or four correspondingly.

[0041] It should be noted that flexibility can be understood as the hardness of the ring segment 121, that is, the hardness of at least two ring segments 121 is different. For example, it is the Shore hardness, which can be measured by a Shore hardness tester. Alternatively, flexibility can also be understood as the elastic modulus, that is, the elastic modulus of at least two ring segments 121 is different. Therefore, flexibility reflects the deformation ability of the ring segment 121. When the same external force is applied in the radial direction of the bearing ring 120, the deformation of at least two ring segments 121 is different. The deformation amounts mentioned in the subsequent embodiments are all compared when the same external force is applied in the radial direction of the bearing ring 120.

[0042] Reference Figure 5 As shown, for the convenience of explanation, the bearing ring 120 includes two ring segments 121, which are respectively a first ring segment 123 and a second ring segment 124 connected to each other; and the rolling body 130 has two, which are respectively a first rolling body 131 and a second rolling body 132. Figure 5 The dotted line shown in is the dividing line, the right part is the first circle segment 123, and the left part is the second circle segment 124. The first rolling body 131 is rotatably arranged in the first installation cavity 122 of the first circle segment 123, and the second rolling body 132 is rotatably arranged in the first installation cavity 122 of the second circle segment 124. The first circle segment 123 and the second circle segment 124 have different deformation amounts when subjected to external forces of the same magnitude, for example, the deformation amount of the first circle segment 123 is less than that of the second circle segment 124. The first circle segment 123 with a small deformation amount mainly plays a positioning role, effectively reducing the deflection and misalignment of the wind wheel 300, and the second circle segment 124 with a large deformation amount mainly plays a role in absorbing the vibration of the wind wheel 300. Therefore, the bearing assembly 100 takes into account both the positioning support and vibration reduction and noise reduction of the rotating shaft 310, further reducing the noise during the operation of the wind wheel 300, and improving the user experience.

[0043] It is understandable that, compared with the state of the impeller 300 when it is running at a high speed, when the impeller 300 is running at a low speed, the impeller 300 is more difficult to balance, and the wind noise of the air conditioner 1000 is small, and the noise when the impeller 300 vibrates is more obvious. Therefore, by adopting a solution with different flexibility of some ring segments 121, the noise of the impeller 300 when running at a low speed can be effectively reduced.

[0044] It should be noted that in another embodiment of the present invention, when subjected to the same external force, the deformation of the first circle segment 123 may be greater than the deformation of the second circle segment 124. When the above scheme is adopted, it can also achieve the effects of supporting positioning and reducing vibration and noise. The appropriate scheme can be selected according to the actual situation.

[0045] Reference Figure 5As shown, in the embodiment of the present invention, the bearing ring 120 has a first end 113 and a second end 114 along its axial direction, for example, the first end 113 is located at the end surface of the first ring segment 123, and the second end 114 is located at the end surface of the second ring segment 124. In the direction from the first end 113 to the second end 114, or in other words, in the direction away from the wind rotor 300, the flexibility of the first ring segment 123 is less than the flexibility of the second ring segment 124, that is, the deformation of the first ring segment 123 is less than the deformation of the second ring segment 124. When the bearing assembly 100 is mounted on the rotating shaft 310, the first ring segment 123 is located at the end of the rotating shaft 310 close to the wind rotor 300, and the second ring segment 124 is located at the end of the rotating shaft 310 away from the wind rotor 300. It can be understood that since the rotating shaft 310 is a cantilever structure, the end of the rotating shaft 310 close to the wind rotor 300 has a small vibration amplitude, and the end of the rotating shaft 310 away from the wind rotor 300 has a large vibration amplitude. Therefore, the first circle segment 123 is located at the end of the rotating shaft 310 close to the wind wheel 300 and mainly plays a supporting and positioning role, while the second circle segment 124 is located at the end of the rotating shaft 310 away from the wind wheel 300 and mainly plays a role of absorbing vibrations, further reducing the noise during the operation of the wind wheel 300, and at the same time can play a role of positioning support, thereby reducing the occurrence of sway and misalignment of the wind wheel 300.

[0046] In order to make the first circle segment 123 and the second circle segment 124 deform differently when subjected to the same external force, Figure 6 and Figure 7 As shown, in the embodiment of the present invention, the first end 113 of the first segment 123 is provided with a first hole 1232, and the first hole 1232 is extended along the axial direction of the bearing ring 120; the second end 114 of the second segment 124 is provided with a second hole 1242, and the second hole 1242 is extended along the axial direction of the bearing ring 120. The cross-sectional area of ​​the first hole 1232 is smaller than the cross-sectional area of ​​the second hole 1242, so the thickness of the first segment 123 and the second segment 124 are different, that is, by changing the structure of the first segment 123 and the second segment 124, the deformation of the first segment 123 is smaller than the deformation of the second segment 124, and the bearing ring 120 can play the role of positioning support and absorbing the vibration of the wind wheel 300, thereby reducing the noise of the wind wheel 300 when it is running.

[0047] Continue to refer to Figure 6 and Figure 7As shown, in the embodiment of the present invention, the end surface of the first ring segment 123 is provided with a first center hole 1231 connected to the first installation cavity 122, and a plurality of first holes 1232 are arranged at intervals and arranged around the first center hole 1231. The end surface of the second ring segment 124 is provided with a second center hole 1241, and the second center hole 1241 is connected to the first center hole 1231 and is arranged coaxially. A plurality of second holes 1242 are arranged at intervals and arranged around the second center hole 1241. The rotating shaft 310 is arranged through the first center hole 1231 and the second center hole 1241, and is connected to the installation holes 133 of the first rolling body 131 and the second rolling body 132.

[0048] It can be understood that the multiple first holes 1232 and the multiple second holes 1242 are respectively arranged around the end surface of the first circle segment 123 and the end surface of the second circle segment 124, which can make the deformation of the first circle segment 123 and the second circle segment 124 in the radial direction uniform, which is convenient for absorbing the vibration of the wind wheel 300 and improving the user experience. Among them, the multiple first holes 1232 are arranged at uniform intervals, and the multiple second holes 1242 are arranged at uniform intervals, which further improves the uniformity of the deformation of the first circle segment 123 and the second circle segment 124 in the radial direction, can better absorb the vibration of the wind wheel 300, and reduce the noise when the wind wheel 300 is running. In another embodiment, the distance between the multiple first holes 1232 and the multiple second holes 1242 can also be unevenly set, and the appropriate solution is selected according to the actual situation.

[0049] In another embodiment of the present invention, in order to make the first segment 123 and the second segment 124 have different deformation amounts when subjected to the same external force, the end surface of the first segment 123 is provided with at least one first hole 1232, and the end surface of the second segment 124 is provided with a plurality of second holes 1242, and the number of the second holes 1242 is greater than the number of the first holes 1232. For example, there are eight first holes 1232 and twelve second holes 1242, or there are four first holes 1232 and ten second holes 1242, so that when the first segment 123 and the second segment 124 are subjected to radial external forces of the same magnitude, the deformation amount of the first segment 123 is less than that of the second segment 124. The first segment 123 mainly plays a role of positioning support due to its small deformation amount, while the second segment 124 can absorb the vibration of the rotating shaft 310 due to its large deformation amount, thereby reducing the noise of the wind wheel 300 during operation.

[0050] In another embodiment of the present invention, the first circle segment 123 and the second circle segment 124 are made of different materials, that is, by changing the materials of the first circle segment 123 and the second circle segment 124, the first circle segment 123 and the second circle segment 124 can have different deformation amounts when subjected to the same external force in the radial direction. The first circle segment 123 and the second circle segment 124 can be manufactured separately during the production stage and then connected by hot melting. Of course, they can also be connected by snap-on connection, fasteners, or not connected. For example, the first circle segment 123 is made of rubber material, and the second circle segment 124 is made of silicone material. Or the first circle segment 123 is made of styrene-butadiene rubber, and the second circle segment 124 is made of chloroprene rubber.

[0051] In another embodiment of the present invention, the first circle segment 123 and the second circle segment 124 may also be made of the same material, for example, both are made of rubber material, but during the production process, different doses of hardness agent, such as calcium silicate, aluminum silicate, etc., may be added to the rubber material, so that the deformation amounts of the first circle segment 123 and the second circle segment 124 are different. The appropriate solution is selected according to the actual situation.

[0052] Reference Figure 5 As shown, in the embodiment of the present invention, along the radial direction of the bearing ring 120, the maximum clearances between at least two rolling bodies 130 and the inner wall of the first mounting cavity 122 are different. For example, the maximum clearance between the first rolling body 131 and the inner wall of the first mounting cavity 122 of the first ring segment 123 is L1, and the maximum clearance between the second rolling body 132 and the inner wall of the first mounting cavity 122 of the second ring segment 124 is L2, and L2 is greater than L1. In order to make L2 greater than L1, the maximum inner diameter of the first mounting cavity 122 of the first ring segment 123 may be the same as the maximum inner diameter of the first mounting cavity 122 of the second ring segment 124, while the maximum outer diameter of the first rolling body 131 may be greater than the maximum outer diameter of the second rolling body 132. Alternatively, the maximum outer diameter of the first rolling body 131 may be equal to the maximum outer diameter of the second rolling body 132, while the maximum inner diameter of the first mounting cavity 122 of the first ring segment 123 may be less than the maximum inner diameter of the first mounting cavity 122 of the second ring segment 124. The appropriate solution is selected according to the actual situation.

[0053] It is understandable that by setting the maximum gaps between at least two rolling bodies 130 and the inner wall of the first installation cavity 122 to be different, the rolling body 130 with a smaller maximum gap mainly plays a role in positioning and supporting the rotating shaft 310, reducing the misalignment and yaw of the rotating shaft 310, and ensuring the stability of the operation of the rotating shaft 310. The rolling body 130 with a larger maximum gap has more space to absorb the vibration of the rotating shaft 310, thereby reducing the noise of the wind wheel 300 when it is running.

[0054] Continue to refer to Figure 5As shown, along the direction from the first end 113 to the second end 114, the maximum gap between the plurality of rolling elements 130 and the inner wall of the first installation cavity 122 gradually increases. When the bearing assembly 100 and the rotating shaft 310 are matched, the first rolling element 131 is located at the position of the rotating shaft 310 close to the wind wheel 300, and the second rolling element 132 is located at the position of the rotating shaft 310 far away from the wind wheel 300. Since the rotating shaft 310 is a cantilever structure, the end of the rotating shaft 310 close to the wind wheel 300 has a small vibration amplitude; the end of the rotating shaft 310 far away from the wind wheel 300 has a large vibration amplitude. Therefore, the maximum gap between the first rolling element 131 and the first ring segment 123 is small, which mainly plays a role in supporting and positioning, while the gap between the second rolling element 132 and the second ring segment 124 is large, which mainly plays a role in absorbing vibration, further reducing the noise during the operation of the wind wheel 300 and improving the user experience.

[0055] It can be understood that the scheme in which the deformation of the first circle segment 123 is smaller than the deformation of the second circle segment 124, and the maximum gap between the first rolling body 131 and the first circle segment 123 is smaller than the maximum gap between the second rolling body 132 and the second circle segment 124 can further improve the effect of vibration reduction and noise reduction, and at the same time has the function of supporting and positioning the rotating shaft 310, which can more effectively reduce the noise during the operation of the wind wheel 300 and improve the user experience.

[0056] Reference Figure 4 and Figure 5 As shown, in the embodiment of the present invention, the bearing assembly 100 further includes a bearing seat 110, the bearing seat 110 is provided with a second mounting cavity 111, the inner wall of the second mounting cavity 111 is provided with a limiting rib 112, and the limiting rib 112 is extended along the circumference of the bearing ring 120. The outer wall of the bearing ring 120 is provided with a limiting groove 150, and the limiting groove 150 can be arranged around the circumference of the bearing ring 120. The bearing ring 120 is installed in the second mounting cavity 111, and the limiting rib 112 is clamped in the limiting groove 150, so as to limit the separation of the bearing ring 120 and the second mounting cavity 111, and can improve the stability of the installation of the bearing ring 120.

[0057] Reference Figure 6 As shown, in the embodiment of the present invention, the outer peripheral walls of the first ring segment 123 and the second ring segment 124 are both provided with a plurality of convex ribs 140, and the plurality of convex ribs 140 are arranged at intervals along the circumference of the first ring segment 123 and the second ring segment 124. When the bearing ring 120 is installed in the second installation cavity 111, the convex ribs 140 can abut against the inner wall of the second installation cavity 111, thereby further limiting the separation of the bearing ring 120 from the second installation cavity 111. The provision of a plurality of convex ribs 140 can further improve the stability of the installation of the bearing ring 120, effectively reduce the loosening and falling of the bearing ring 120, and improve the reliability of the bearing assembly 100.
