Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and more specifically, to a bearing housing assembly and an air conditioner. Background Technology

[0002] A residential wall-mounted air conditioner contains conventional parts such as a bearing housing, bearing ring, bearing, cross-flow fan blades, and a base. The bearing housing is mounted on the base, the bearing ring is pressed into the bearing housing through elastic deformation, the bearing is interference-fitted into the bearing ring, and the shaft of the cross-flow fan blades passes through the bearing. The bearing is filled with lubricating oil, and the rotation of the shaft promotes the flow of lubricating oil, allowing it to easily flow out from the shaft hole of the bearing ring and along the end face of the bearing ring onto the base.

[0003] However, the bearing gaskets are made of rubber and play a role in vibration damping and noise reduction during the operation of the cross-flow fan. These gaskets contain plasticizers such as DOP and ATBC, while the base components are generally made of ABS or HIPS plastic. ABS and HIPS plastics are prone to corrosion and cracking when in contact with plasticizers such as DOP and ATBC. Furthermore, lubricating oil accelerates the precipitation of plasticizers when it comes into contact with the bearing gaskets. When lubricating oil mixed with plasticizers such as DOP and ATBC flows onto the base, it can cause corrosion and cracking of the base. Utility Model Content

[0006] Furthermore, the closed end of the bearing housing is provided with an exhaust hole, and the axial outer wall of the bearing ring away from the first connecting hole is provided with a plurality of first annular protrusions. Each first annular protrusion protrudes along the axial direction of the bearing ring, and the plurality of first annular protrusions are distributed around the bearing ring from the inside to the outside along the radial direction of the bearing ring. The exhaust hole is located between any two of the plurality of first annular protrusions, so as to abut against the closed end of the bearing housing through the first annular protrusions to seal the exhaust hole.

[0007] Furthermore, the bearing housing is provided with an installation cavity, and two second annular protrusions are provided on the circumferential inner wall of the installation cavity. The second annular protrusions protrude along the radial direction of the bearing housing to divide the installation cavity into a first cavity and a second cavity. The first cavity is used to install the bearing rubber ring, and the circumferential cavity wall of the second cavity and the two second annular protrusions together form an oil reservoir.

[0008] Furthermore, the maximum radial length of the first cavity is h1, and the distance between the two second annular protrusions along the axial direction of the bearing seat is h2, where h2 ≥ 0.1h1.

[0009] Furthermore, connecting ribs are provided on the circumferential outer wall of the bearing ring, and the connecting ribs all extend along the axial direction of the bearing ring and abut against the circumferential inner wall of the first cavity; wherein, there are multiple connecting ribs, and the multiple connecting ribs are spaced apart along the circumferential direction of the bearing ring.

[0010] Furthermore, the bearing ring is provided with a mounting groove for mounting the bearing, and a limiting groove extending along the axial direction of the bearing ring is provided inside the bearing ring. The limiting groove passes through the mounting groove, and the end of the limiting groove is used to form a first connecting hole.

[0011] Furthermore, an annular recess is provided at the axial end of the bearing ring near the first connecting hole, and the annular recess is recessed along the axial direction of the bearing ring.

[0012] Furthermore, the first cavity includes a third cavity and a fourth cavity that are interconnected. The fourth cavity is located on the side of the third cavity near the second cavity. The length of the fourth cavity in the radial direction along the bearing seat is greater than the length of the third cavity in the radial direction along the bearing seat. The length of the fourth cavity in the radial direction along the bearing seat is the same as the length of the second cavity in the radial direction along the bearing seat. The inner diameter of the second annular protrusion is the same as the length of the third cavity in the radial direction along the bearing seat.

[0013] Furthermore, the bearing ring has a first bearing segment and a second bearing segment connected to each other. The shape of the first bearing segment is adapted to the shape of the third cavity, and the shape of the second bearing segment is adapted to the shape of the fourth cavity.

The end of the bearing housing near the first connecting hole is an open end, equipped with an oil reservoir connected to the first connecting hole. This allows the oil reservoir to actively collect and store oil that may overflow from the first connecting hole due to the relative movement between the bearing and the shaft, effectively intercepting oil overflowing from the bearing and preventing it from falling directly from the bearing housing onto the air conditioner's bottom casing. Therefore, the bearing housing can completely block the path of direct contact between the oil and the bottom casing, thus solving the problem in the prior art where lubricating oil mixed with plasticizers such as DOP and ATBC causes corrosion and cracking of the bottom casing when it flows onto it. This reduces the probability of bottom casing cracking, decreases the frequency of bottom casing replacement or repair, thereby reducing maintenance costs and extending the service life of the bottom casing.

[0029] Please refer to Figures 1 to 6This utility model provides a bearing housing assembly, including: a bearing housing 1 and a bearing ring 2. The bearing ring 2 is disposed inside the bearing housing 1, and a bearing 3 is disposed inside the bearing ring 2. The axial end of the bearing ring 2 is provided with a first connecting hole 101 for a rotating shaft 4 to pass through and enter the bearing 3. The end of the bearing housing 1 away from the first connecting hole 101 is a closed end, and the end of the bearing housing 1 near the first connecting hole 101 is an open end. The open end is provided with an oil storage tank 11, which is connected to the first connecting hole 101 to collect the oil flowing out from the first connecting hole 101.

[0030] The bearing housing assembly of this utility model includes a bearing housing 1 and a bearing ring 2. The axial end of the bearing ring 2 is provided with a first connecting hole 101. The end of the bearing housing 1 furthest from the first connecting hole 101 is a closed end to prevent oil in the first connecting hole 101 from flowing out from the closed end and falling onto the bottom shell 6 of the air conditioner. The end of the bearing housing 1 closest to the first connecting hole 101 is an open end, and an oil storage tank 11 is provided at the open end. The oil storage tank 11 is connected to the first connecting hole 101, allowing the oil storage tank to actively collect and store oil due to the relative movement between the bearing 3 and the rotating shaft 4. The oil in the first connecting hole 101, which may overflow, is effectively intercepted from the bearing 3, preventing the oil from falling directly from the bearing seat 1 to the bottom shell 6 of the air conditioner. Therefore, the bearing seat 1 can block the path of direct contact between the oil and the bottom shell in all directions, thereby solving the problem of corrosion and cracking of the bottom shell caused by lubricating oil mixed with plasticizers such as DOP and ATBC flowing onto the bottom shell in the prior art. This reduces the probability of bottom shell cracking, reduces the frequency of bottom shell replacement or repair, thereby reducing maintenance costs and extending the service life of the bottom shell.

[0031] In this embodiment, the closed end of the bearing housing 1 is provided with an exhaust hole 7, and the axial outer wall of the bearing ring 2 away from the first connecting hole 101 is provided with a plurality of first annular protrusions 14. Each first annular protrusion 14 protrudes along the axial direction of the bearing ring 2, and the plurality of first annular protrusions 14 are distributed from the inside to the outside along the radial direction of the bearing ring 2. The exhaust hole 7 is located between any two of the plurality of first annular protrusions 14, so that the first annular protrusions 14 abut against the closed end of the bearing housing 1 to seal the exhaust hole 7.

[0032] Specifically, when the bearing ring 2 is installed into the bearing housing 1, the vent hole is used to discharge the air inside the bearing housing 1, so as to avoid the air compression inside the bearing housing 1 causing resistance and resulting in improper assembly; the vent hole 7 is located between any two of the multiple first annular protrusions 14, so as to abut against the closed end of the bearing housing 1 through the first annular protrusion 14 to seal the vent hole 7, which can prevent external air from flowing into the bearing housing 1 and the air duct of the air conditioner from the vent hole 7, and generating condensation inside the air duct of the air conditioner, thereby ensuring the normal operation of the air conditioner.

[0033] Optionally, there are two to four first annular protrusions 14.

[0034] In this embodiment, the bearing housing 1 is provided with an installation cavity. Two second annular protrusions 12 are provided on the circumferential inner wall of the installation cavity. The second annular protrusions 12 protrude along the radial direction of the bearing housing 1 to divide the installation cavity into a first cavity and a second cavity 201. The first cavity is used to install the bearing rubber ring 2. The circumferential cavity wall of the second cavity 201 and the two second annular protrusions 12 together form an oil reservoir 11.

[0035] Specifically, through the setting of the second annular protrusion 12, the mounting cavity is effectively divided into a first cavity and a second cavity 201. The first cavity is specifically used to accommodate the bearing ring 2, providing it with precise spatial positioning and appropriate compression fit, ensuring the stability and sealing of the bearing ring 2 during operation. The second annular protrusion 12 and the circumferential cavity wall of the second cavity 201 together form an oil reservoir 11. The design of the oil reservoir 11 can actively capture and store the oil overflowing from the bearing ring 2, preventing the oil from flowing directly to the bottom shell.

[0036] In this embodiment, the maximum radial length of the first cavity is h1, and the distance between the two second annular protrusions 12 along the axial direction of the bearing seat 1 is h2, wherein h2≥0.1h1.

[0037] Specifically, this arrangement ensures that the oil reservoir 11 has enough space to collect and store the oil overflowing from the bearing ring 2, and prevents the oil in the oil reservoir 11 from easily leaking onto the bottom shell due to the narrow width of the oil reservoir 1.

[0038] Optionally, the distance between the two second annular protrusions 12 along the axial direction of the bearing housing 1 is h2, that is, the width of the oil reservoir 11 is not less than 3.5mm.

[0039] In this embodiment, a connecting rib 16 is provided on the circumferential outer wall of the bearing ring 2. The connecting rib 16 extends along the axial direction of the bearing ring 2 and abuts against the circumferential inner wall of the first cavity. There are multiple connecting ribs 16, and the multiple connecting ribs 16 are spaced apart along the circumferential direction of the bearing ring 2.

[0040] Specifically, the multiple connecting ribs 16 spaced circumferentially along the bearing ring 2 ensure multi-point contact between the bearing ring 2 and the circumferential inner wall of the first cavity during assembly. This multi-point contact design helps to distribute pressure and avoids deformation or damage caused by excessive pressure on a single contact point, thereby enhancing assembly stability. The connecting ribs 16 are interference-fitted with the first cavity of the bearing housing 1, and the multiple connecting ribs 16 abut against the circumferential inner wall of the first cavity, which avoids excessive assembly resistance caused by an interference fit between the entire circumferential sidewall of the bearing ring 2 and the first cavity of the bearing housing 1. Compared to the design where the entire circumferential sidewall of the bearing ring 2 contacts the first cavity of the bearing housing 1, the design of multiple spaced connecting ribs 16 uses less material, reducing manufacturing costs. At the same time, due to the reduction in material usage, the weight of the bearing ring 2 is also reduced.

[0041] Specifically, the axial section of the connecting rib 16 is semi-circular.

[0042] In this embodiment, the bearing ring 2 is provided with a mounting groove 19 for mounting the bearing 3, and a limiting groove 22 extending along the axial direction of the bearing ring 2 is provided in the bearing ring 2. The limiting groove 22 penetrates the mounting groove 19, and the end of the limiting groove 22 is used to form a first connecting hole 101.

[0043] Specifically, the design of the mounting groove 19 provides a precise installation position for the bearing 3, ensuring a tight fit between the bearing ring 2 and the bearing 3. This reduces axial and radial displacement during bearing 3 operation, ensuring concentricity between the bearing 3 and the shaft, thereby improving the installation accuracy of the bearing 3, reducing vibration and noise caused by bearing position deviation, and enhancing the smooth operation of the air conditioner and user comfort. The limiting groove 22 is used to accommodate the shaft and limit its movement. The first connecting hole 101 formed at the end of the limiting groove 22 is connected to the oil reservoir 11 in the bearing housing 1, providing a flow path for oil that may overflow from the mounting groove 19 during bearing 3 operation. This allows the oil to flow from the mounting groove 19 to the limiting groove 22 and then into the oil reservoir 11, preventing the oil from directly contacting the casing or other sensitive components. This ensures that even under high centrifugal force, the oil will be guided to the oil storage tank 11 for collection, rather than scattered on the bottom shell surface. This reduces the precipitation and mixing of plasticizers, thereby preventing the bottom shell from corroding and cracking due to contact with lubricating oil mixed with plasticizers, and extending the service life of the air conditioner.

[0044] In this embodiment, an annular recess 21 is provided at the axial end of the bearing ring 2 near the first connecting hole 101, and the annular recess 21 is recessed along the axial direction of the bearing ring 2.

[0045] Specifically, the annular recess 21 facilitates the deformation of the bearing ring 2 by the bearing housing 1 during assembly, reducing the assembly difficulty of the bearing housing 1 and the bearing ring 2. Specifically, when the bearing ring 2 needs to be inserted into the bearing housing 1, the first cavity will compress the bearing ring 2 near the annular recess 21. Because there is deformation space between the annular recesses 21, the bearing ring 2 near the annular recesses 21 deforms more easily, helping the bearing ring 2 to be fully inserted into the first cavity of the bearing housing 1, thus facilitating the smooth assembly of the bearing housing 1 and the bearing ring 2.

[0046] In this embodiment, the first cavity includes a third cavity 9 and a fourth cavity 10 that are interconnected. The fourth cavity 10 is disposed on the side of the third cavity 9 near the second cavity 201. The length of the fourth cavity 10 along the radial direction of the bearing seat 1 is greater than the length of the third cavity 9 along the radial direction of the bearing seat 1. The length of the fourth cavity 10 along the radial direction of the bearing seat 1 is the same as the length of the second cavity 201 along the radial direction of the bearing seat 1. The inner diameter of the second annular protrusion 12 is the same as the length of the third cavity 9 along the radial direction of the bearing seat 1.

[0047] Specifically, the bearing housing 1 is made of oil-resistant and corrosion-resistant material; the length of the third cavity 9 along the radial direction of the bearing housing 1 is more than 6 mm smaller than the length of the fourth cavity 10 along the radial direction of the bearing housing 1.

[0048] In this embodiment, the bearing ring 2 has a first bearing segment 15 and a second bearing segment 17 connected to each other. The shape of the first bearing segment 15 is adapted to the shape of the third cavity 9, and the shape of the second bearing segment 17 is adapted to the shape of the fourth cavity 10. The axial end of the second bearing segment 17 abuts against the axial end of the second annular protrusion 12.

[0049] Specifically, the first cavity is subdivided into a third cavity 9 and a fourth cavity 10, and these two cavities are interconnected. The fourth cavity 10 is located on the side of the third cavity 9 near the second cavity 201. The length of the fourth cavity 10 along the radial direction of the bearing housing 1 is greater than that of the third cavity 9, ensuring that the shape of the smaller diameter first bearing rubber segment 15 matches the shape of the third cavity 9, and the shape of the larger diameter second bearing rubber segment 17 matches the shape of the fourth cavity 10. This ensures a smooth transition during the assembly of the bearing ring 2, reduces the assembly difficulty of the bearing ring 2, and improves assembly efficiency. The smaller radial dimension of the first bearing rubber segment 15 facilitates initial positioning, while the larger dimension of the second bearing rubber segment 17 ensures final tight sealing and positioning.

[0050] Specifically, the fourth cavity 10 has the same radial length as the second cavity 201, ensuring a smooth transition of the bearing ring 2 during assembly. Simultaneously, the axial end of the second bearing segment 17 abuts against the axial end of the second annular protrusion 12. The inner diameter of the second annular protrusion 12 is the same as the radial length of the third cavity 9, ensuring that the second annular protrusion 12 can limit the position of the second bearing segment 17. The second bearing segment 17 will be stably positioned within the fourth cavity 10, preventing it from sliding out.

[0051] In practice, when installing the bearing ring 2, the smaller diameter first bearing segment 15 enters the bearing housing 1 first, and then the larger diameter second bearing segment 17 enters the bearing housing 1, which helps to reduce the assembly difficulty of the bearing ring 2 and the bearing housing 1.

[0052] In this embodiment, the axial end of the first bearing rubber segment 15 away from the second bearing rubber segment 17 is provided with a chamfered structure / beveled structure, and the axial end of the second bearing rubber segment 17 near the first bearing rubber segment 15 is provided with a chamfered structure / beveled structure.

[0053] Specifically, during the assembly of the bearing ring 2 and the bearing housing 1, the contact between the bearing ring 2 and the bearing housing 1 may generate significant resistance. By providing a chamfered / angled structure at the axial end of the first bearing segment 15 away from the second bearing segment 17, and a chamfered / angled structure at the axial end of the second bearing segment 17 near the first bearing segment 15, the bearing ring 2 can more easily enter the first cavity in the initial stage. This reduces the pressure on the bearing ring 2, thereby preventing material deformation or damage to the bearing ring 2 due to excessive compression, and ensuring the integrity of the bearing ring 2.

[0054] Optionally, the axial end of the first bearing rubber segment 15 away from the second bearing rubber segment 17 is provided with a first chamfer structure 18, and the axial end of the second bearing rubber segment 17 near the first bearing rubber segment 15 is provided with a first bevel structure 20.

[0055] This utility model also provides an air conditioner, including the above-mentioned bearing housing assembly.

[0056] The air conditioner of this utility model also includes a cross-flow fan blade 5 and a bottom shell 6. The bearing housing 1 is mounted on the bottom shell 6. The bearing rubber ring 2 is pressed into the bearing housing 1 through elastic deformation. The bearing 3 is interference-fitted into the mounting groove 19 of the bearing rubber ring 2. The rotating shaft 4 of the cross-flow fan blade 5 is inserted into the bearing 3. The bearing 3 is a sliding bearing, and its interior is filled with lubricating oil. When the rotating shaft 4 rotates, it will cause the lubricating oil to flow. The bearing rubber ring 2 is made of rubber material and plays a role in vibration reduction and noise reduction when the cross-flow fan blade 5 is running. It contains a lot of plasticizers such as DOP and ATBC.

[0057] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0058] The bearing housing assembly of this utility model includes a bearing housing 1 and a bearing ring 2. The axial end of the bearing ring 2 is provided with a first connecting hole 101. The end of the bearing housing 1 furthest from the first connecting hole 101 is a closed end to prevent oil in the first connecting hole 101 from flowing out from the closed end and falling onto the bottom shell 6 of the air conditioner. The end of the bearing housing 1 closest to the first connecting hole 101 is an open end, and an oil storage tank 11 is provided at the open end. The oil storage tank 11 is connected to the first connecting hole 101, allowing the oil storage tank to actively collect and store oil due to the relative movement between the bearing 3 and the rotating shaft 4. The oil in the first connecting hole 101, which may overflow, is effectively intercepted from the bearing 3, preventing the oil from falling directly from the bearing seat 1 to the bottom shell 6 of the air conditioner. Therefore, the bearing seat 1 can block the path of direct contact between the oil and the bottom shell in all directions, thereby solving the problem of corrosion and cracking of the bottom shell caused by lubricating oil mixed with plasticizers such as DOP and ATBC flowing onto the bottom shell in the prior art. This reduces the probability of bottom shell cracking, reduces the frequency of bottom shell replacement or repair, thereby reducing maintenance costs and extending the service life of the bottom shell.
