Description

Compressor bearing sleeve TECHNICAL FIELD

[0001] The present application relates to the technical field of bearing sleeve production, in particular to a compressor bearing sleeve. BACKGROUND

[0002] With the long-term use of the bearing sleeve, the wear between the bearing sleeve and the bearing will gradually increase, and the size of the bearing sleeve will change under the condition of continuous wear, thereby causing the deformation of the inner diameter of the bearing sleeve, and further affecting the fitting accuracy of the bearing sleeve and the shaft or the bearing, which is not conducive to the long-term use of the bearing.

[0003] In the related art, when the fitting accuracy between the bearing sleeve and the bearing decreases, a new bearing sleeve needs to be replaced to ensure the normal operation of the bearing. However, the bearing sleeve and the bearing are often sealed by a corresponding sealing cover, which makes it difficult to directly observe the specific wear condition between the bearing sleeve and the bearing.

[0004] At present, the conventional method for checking the wear condition between the bearing sleeve and the bearing is to disassemble the bearing sleeve and the bearing, then check the bearing sleeve and the bearing, and assemble the bearing sleeve and the bearing together again if it is found that the bearing sleeve does not need to be replaced. This checking method is too cumbersome, and the bearing sleeve and the bearing need to be disassembled and assembled every time, which is very inconvenient and has low checking efficiency.

[0005] SUMMARY

[0006] The present application provides a compressor bearing sleeve, which aims to improve the efficiency of checking the wear condition between the bearing sleeve and the bearing, and thereby facilitate the judgment of whether the bearing sleeve needs to be replaced.

[0007] The present application provides a compressor bearing sleeve, which adopts the following technical scheme:

[0008] The compressor bearing sleeve comprises a shaft sleeve, sealing covers are arranged on the upper and lower sides of the shaft sleeve, a first liquid leakage hole is formed through the side wall of the sealing cover arranged at the bottom of the shaft sleeve, and the first liquid leakage hole is in communication with lubricating oil filled between the shaft sleeve and the bearing; an opening and closing assembly is arranged at the bottom of the sealing cover, and the opening and closing assembly is used for opening or closing the first liquid leakage hole on the sealing cover.

[0009] By adopting the above technical scheme, the first liquid leakage hole is sealed by the opening and closing assembly during the normal use of the shaft sleeve and the bearing, so as to effectively prevent the lubricating oil from leaking from the first liquid leakage hole; when it is necessary to check the wear condition between the shaft sleeve and the bearing, the first liquid leakage hole is opened by the opening and closing assembly, at this time, the lubricating oil between the shaft sleeve and the bearing will leak from the first liquid leakage hole. The leaked lubricating oil is collected and detected and analyzed by a lubricating oil abrasive particle analyzer.

[0010] During the wear process of the shaft sleeve and the bearing, the particles worn off will fall into the lubricating oil, and the lubricating oil abrasive particle analyzer can analyze the related information such as the type, quantity and size of the abrasive particles in the lubricating oil, so as to evaluate the wear condition between the shaft sleeve and the bearing, and predict potential wear safety hazard problems according to the detection results.

[0011] In this way, when checking the wear condition between the shaft sleeve and the bearing, only the first oil leakage hole needs to be opened by the opening and closing assembly to collect the lubricating oil, and the shaft sleeve and the bearing do not need to be repeatedly disassembled and assembled for monitoring. Therefore, the efficiency of checking the wear condition between the shaft sleeve and the bearing can be significantly improved, and whether the shaft sleeve needs to be replaced can be conveniently judged. At the same time, the shaft sleeve and the bearing do not need to be disassembled and assembled, and the structural damage of the shaft sleeve and the bearing caused by disassembly can be effectively prevented.

[0012] Preferably, the first oil leakage hole is an internally threaded hole, and the opening and closing assembly is a screw rod which is threadedly installed in the first oil leakage hole.

[0013] By using the above technical solution, when the shaft sleeve and the bearing are normally working, the screw rod is screwed in the first oil leakage hole, and the nut of the screw rod is tightly attached to the shaft sleeve. When the wear condition of the shaft sleeve and the bearing needs to be checked, the screw rod is removed from the first oil leakage hole, so that the lubricating oil between the shaft sleeve and the bearing can smoothly flow out of the first oil leakage hole, and then the corresponding lubricating oil can be detected and analyzed by the lubricating oil abrasive particle analyzer.

[0014] Preferably, the opening and closing assembly is an annular oil outlet plate which is tightly connected to the sealing cover, a second oil leakage hole is formed in the oil outlet plate, the shape and size of the second oil leakage hole are the same as those of the first oil leakage hole, the second oil leakage hole and the first oil leakage hole are misaligned, the oil outlet plate is rotationally connected to the sealing cover at the bottom of the shaft sleeve, and the oil outlet plate is used to connect or seal the first oil leakage hole and the second oil leakage hole.

[0015] By using the above technical solution, when the shaft sleeve and the bearing are normally working, in this state, the top of the oil outlet plate seals the first oil leakage hole on the sealing cover, and the lubricating oil between the shaft sleeve and the bearing is effectively prevented from leaking by the oil outlet plate.

[0016] When the wear condition between the shaft sleeve and the bearing needs to be detected, the oil outlet plate is rotated so that the multiple second oil leakage holes on the oil outlet plate are aligned with the multiple first oil leakage holes on the sealing cover. In this state, the first oil leakage hole and the second oil leakage hole are connected, and the lubricating oil between the shaft sleeve and the bearing flows from the first oil leakage hole to the second oil leakage hole for leakage. After the lubricating oil is collected, the oil outlet plate is rotated again so that the first oil leakage hole and the second oil leakage hole are misaligned with each other.

[0017] In this way, when collecting the lubricating oil between the shaft sleeve and the bearing, only the oil outlet plate needs to be rotated. After collection, the oil outlet plate is rotated again to seal the first liquid leakage hole on the sealing cover, which is simple and efficient.

[0018] Preferably, the side of the sealing cover away from the shaft sleeve is folded away from the shaft sleeve, and the bottom of the fold is integrally formed with a rotating disc in the horizontal direction, the rotating disc is coaxially connected with the fold, and the top of the rotating disc is recessed with a rotating groove away from the sealing cover along the circumferential side thereof; the side of the oil outlet plate away from the sealing cover is integrally formed with a rotating plug along the circumferential side thereof, and the rotating plug is inserted into the rotating groove.

[0019] By adopting the above technical scheme, the oil outlet plate and the sealing cover are installed in a rotating manner by using the rotating plug and the rotating groove, and then the opening and closing of the first liquid leakage hole on the sealing cover are controlled by rotating the oil outlet plate.

[0020] Preferably, the first liquid leakage hole and the second liquid leakage hole are both provided in multiple numbers, the multiple first liquid leakage holes are uniformly distributed along the circumferential side of the sealing cover, and the multiple second liquid leakage holes are uniformly distributed along the circumferential side of the oil outlet plate.

[0021] By adopting the above technical scheme, the first liquid leakage hole and the second liquid leakage hole are provided in multiple numbers, and when detecting the wear between the shaft sleeve and the bearing, the lubricating oil at different positions between the shaft sleeve and the bearing can be collected by using the multiple first liquid leakage holes and the multiple second liquid leakage holes, and then the lubricating oil at different positions between the shaft sleeve and the bearing can be detected and analyzed, which makes the entire detection more accurate and the detection effect better.

[0022] Preferably, the side wall of the oil outlet plate is integrally formed with a push rod.

[0023] By adopting the above technical scheme, the push rod is used to facilitate the rotation of the oil outlet plate, which is more convenient to use and better in experience.

[0024] Preferably, a sealing plate is additionally arranged below the oil outlet plate, the sealing plate has a whole "N" shape structure, the left and right side plates of the sealing plate are inserted on the oil outlet plate through corresponding plugs, and the side plates and the bottom plate of the sealing plate seal the oil outlet plate.

[0025] By adopting the technical scheme, although the oil outlet plate and the sealing cover are in close contact when the shaft sleeve and the bearing are normally working, and the first oil leakage hole and the second oil leakage hole are staggered with each other, it is almost impossible to leak oil. However, during the operation of the bearing, vibration will inevitably occur between the oil outlet plate and the sealing cover, which will cause a gap between the oil outlet plate and the sealing cover, and the lubricating oil will leak from the first oil leakage hole to the gap between the oil outlet plate and the sealing cover, and then flow to the second oil leakage hole or directly leak from the edge of the oil outlet plate.

[0026] The sealing plate can effectively prevent the lubricating oil from leaking from the oil outlet plate.

[0027] Preferably, a sealing groove and a sealing ring are further arranged between the oil outlet plate and the sealing cover, the sealing groove is arranged along the bottom edge of the sealing cover, the sealing ring is integrally formed on the top of the oil outlet plate along the circumferential side of the oil outlet plate, and the sealing ring is inserted into the sealing groove.

[0028] By adopting the technical scheme, the sealing groove and the sealing ring are used to seal the circumferential side of the sealing cover and the oil outlet plate, thereby effectively preventing the lubricating oil from leaking from the circumferential side of the sealing cover and the oil outlet plate. At the same time, during the rotation of the oil outlet plate, the sealing ring and the sealing groove guide the rotation of the oil outlet plate, thereby facilitating the stability of the rotation of the oil outlet plate.

[0029] In summary, the present application has at least one of the following beneficial technical effects:

[0030] 1. During normal use of the shaft sleeve and the bearing, the opening and closing assembly seals the first oil leakage hole to effectively prevent the lubricating oil from leaking from the first oil leakage hole; when it is necessary to check the wear condition between the shaft sleeve and the bearing, the opening and closing assembly opens the first oil leakage hole, at this time, the lubricating oil between the shaft sleeve and the bearing will leak from the first oil leakage hole. The leaked lubricating oil is collected and detected and analyzed by a lubricating oil abrasive particle analyzer.

[0031] During the wear of the shaft sleeve and the bearing, the particles worn off will fall into the lubricating oil, and the lubricating oil abrasive particle analyzer can analyze the related information such as the type, quantity and size of the abrasive particles in the lubricating oil, so as to evaluate the wear condition between the shaft sleeve and the bearing, and predict potential wear safety hidden trouble problems according to the detection results.

[0032] The setting mode can only collect the lubricating oil by opening the first oil leakage hole through the opening and closing assembly when checking the wear condition between the shaft sleeve and the bearing, and the shaft sleeve and the bearing do not need to be repeatedly disassembled for monitoring. Therefore, the efficiency of checking the wear condition between the shaft sleeve and the bearing can be significantly improved, and whether the shaft sleeve needs to be replaced can be conveniently judged. Meanwhile, the shaft sleeve and the bearing do not need to be disassembled, and the structural damage of the shaft sleeve and the bearing caused by disassembly can be effectively prevented.

[0033] 2. When the shaft sleeve and the bearing are normally working, the top of the oil outlet plate seals the first oil leakage hole on the sealing cover, and the lubricating oil between the shaft sleeve and the bearing is effectively prevented from leaking through the oil outlet plate.

[0034] When the wear condition between the shaft sleeve and the bearing needs to be detected, the oil outlet plate is rotated, so that the plurality of second oil leakage holes on the oil outlet plate are aligned with the plurality of first oil leakage holes on the sealing cover. In this state, the first oil leakage hole and the second oil leakage hole are connected, and the lubricating oil between the shaft sleeve and the bearing leaks from the first oil leakage hole to the second oil leakage hole. After the lubricating oil is collected, the oil outlet plate is rotated again, so that the first oil leakage hole and the second oil leakage hole are misaligned with each other.

[0035] The setting mode only needs to rotate the oil outlet plate when the lubricating oil between the shaft sleeve and the bearing needs to be collected. After the collection is completed, the first oil leakage hole on the sealing cover can be sealed through the oil outlet plate by rotating the oil outlet plate again. The operation is simple and efficient.

[0036] 3. Although the oil outlet plate and the sealing cover are in close contact when the shaft sleeve and the bearing are normally working, and the first oil leakage hole and the second oil leakage hole are misaligned with each other at this time, it is almost impossible to leak oil. However, during the operation of the bearing, vibration will inevitably occur between the oil outlet plate and the sealing cover, which will cause a gap between the oil outlet plate and the sealing cover. The lubricating oil will leak from the first oil leakage hole to the gap between the oil outlet plate and the sealing cover, and then flow to the second oil leakage hole or directly leak from the edge of the oil outlet plate.

[0037] The sealing plate can effectively prevent the lubricating oil from leaking from the oil outlet plate;

[0038] The sealing groove and the sealing ring seal the edge of the sealing cover and the oil outlet plate. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0044] The present application will be further described in detail below in conjunction with Figures 1-4.

[0045] Example 1:

[0046] The present application discloses a compressor bearing sleeve, referring to Figure 1, which comprises a ring-shaped shaft sleeve 1. The corresponding bearing sleeve is arranged in the inner cavity of the shaft sleeve 1. The inner ring of the shaft sleeve 1 and the bearing are filled with balls. After the bearing and the balls are assembled with the shaft sleeve 1, sealing covers 2 are added between the upper and lower sides of the shaft sleeve 1 and the outer ring of the bearing. The sealing covers 2 are manually arranged between the shaft sleeve 1 and the bearing and are tightly connected with the shaft sleeve 1 and the bearing by corresponding mechanical pressing. Before installation, the sealing covers 2 are filled with lubricating oil on the balls between the bearing sleeve and the bearing. The sealing covers 2 seal the lubricating oil to effectively prevent the loss of lubricating oil.

[0047] Referring to Figure 1, a circular first liquid leakage hole 3 is provided through the side wall of the sealing cover 2 installed at the bottom of the shaft sleeve 1. The first liquid leakage hole 3 is in communication with the lubricating oil filled between the shaft sleeve 1 and the bearing. At the same time, an opening and closing assembly is added at the bottom of the sealing cover 2. The opening and closing assembly is used to open or close the first liquid leakage hole 3 on the sealing cover 2.

[0048] During normal use of the shaft sleeve 1 and the bearing, the opening and closing assembly seals the first liquid leakage hole 3 to effectively prevent the loss of lubricating oil from the first liquid leakage hole 3. When it is necessary to check the wear condition between the shaft sleeve 1 and the bearing, the first liquid leakage hole 3 is opened by the opening and closing assembly. At this time, the lubricating oil between the shaft sleeve 1 and the bearing will leak from the first liquid leakage hole 3. The leaked lubricating oil is collected and detected and analyzed by a lubricating oil abrasive particle analyzer.

[0049] During the wear process of the shaft sleeve 1 and the bearing, the particles worn down will fall into the lubricating oil. The lubricating oil abrasive particle analyzer can analyze the types, quantities and sizes of the abrasive particles in the lubricating oil, so as to evaluate the wear condition between the shaft sleeve 1 and the bearing, and predict potential wear safety hidden problems according to the detection results.

[0050] The setting mode can only collect the lubricating oil by opening the first oil leakage hole 3 through the opening and closing assembly when checking the wear condition between the shaft sleeve 1 and the bearing, without the need of repeatedly assembling and disassembling the shaft sleeve 1 and the bearing, so that the efficiency of checking the wear condition between the shaft sleeve 1 and the bearing can be improved, and whether the shaft sleeve 1 needs to be replaced can be determined. Meanwhile, the shaft sleeve 1 and the bearing can be effectively prevented from being damaged in the disassembly process.

[0051] Specifically, referring to FIG. 1, in the embodiment, the first oil leakage hole 3 is an internal thread hole, and the opening and closing assembly is a screw rod 4 which is threadedly installed in the first oil leakage hole 3.

[0052] When the shaft sleeve 1 and the bearing are normally working, the screw rod 4 is screwed in the first oil leakage hole 3, and the nut of the screw rod 4 is tightly attached to the shaft sleeve 1. When the wear condition of the shaft sleeve 1 and the bearing needs to be checked, the screw rod 4 is removed from the first oil leakage hole 3, so that the lubricating oil between the shaft sleeve 1 and the bearing can flow out of the first oil leakage hole 3, and then the corresponding lubricating oil can be detected and analyzed by the lubricating oil abrasive particle analyzer.

[0053] In the embodiment, the first oil leakage hole 3 is provided in multiple, and the multiple first oil leakage holes 3 are uniformly distributed on the bottom sealing cover 2 of the shaft sleeve 1. By providing the first oil leakage hole 3 in multiple, the lubricating oil at different positions between the shaft sleeve 1 and the bearing can be collected by the multiple first oil leakage holes 3 when the wear condition between the shaft sleeve 1 and the bearing is detected, so that the lubricating oil at different positions between the shaft sleeve 1 and the bearing can be detected and analyzed, which makes the whole detection more accurate and the detection effect better.

[0054] The implementation principle of the compressor bearing sleeve in the embodiment of the application is as follows:

[0055] When the wear condition between the shaft sleeve 1 and the bearing needs to be checked, the lubricating oil can be collected by opening the first oil leakage hole 3 through the opening and closing assembly, without the need of repeatedly assembling and disassembling the shaft sleeve 1 and the bearing, so that the efficiency of checking the wear condition between the shaft sleeve 1 and the bearing can be improved, and whether the shaft sleeve 1 needs to be replaced can be determined. Meanwhile, the shaft sleeve 1 and the bearing can be effectively prevented from being damaged in the disassembly process.

[0056] Meanwhile, the first oil leakage hole 3 is provided in multiple, and the lubricating oil at different positions between the shaft sleeve 1 and the bearing can be collected by the multiple first oil leakage holes 3 when the wear condition between the shaft sleeve 1 and the bearing is detected, so that the lubricating oil at different positions between the shaft sleeve 1 and the bearing can be detected and analyzed, which makes the whole detection more accurate and the detection effect better.

[0057] Embodiment 2

[0058] Referring to FIG. 1 and FIG. 3, in the present embodiment, the opening and closing assembly is a ring-shaped oil outlet plate 5, the oil outlet plate 5 is rotatably installed at the sealing cover 2 at the bottom of the shaft sleeve 1, and the oil outlet plate 5 is tightly connected with the sealing cover 2. The oil outlet plate 5 is uniformly and spacedly provided with a plurality of circular second oil leakage holes 6 along the circumferential side thereof, and the size and shape of the second oil leakage holes 6 and the first oil leakage holes 3 are kept the same. During normal operation of the shaft sleeve 1 and the bearing, the second oil leakage holes 6 and the first oil leakage holes 3 are kept misaligned with each other, that is, the second oil leakage holes 6 and the first oil leakage holes 3 are not communicated with each other.

[0059] In this state, the top of the oil outlet plate 5 plays a sealing role on the first oil leakage holes 3 on the sealing cover 2, effectively preventing the lubricating oil between the shaft sleeve 1 and the bearing from leaking.

[0060] When it is necessary to detect the wear condition between the shaft sleeve 1 and the bearing, the oil outlet plate 5 is rotated so that the plurality of second oil leakage holes 6 on the oil outlet plate 5 are aligned one by one with the plurality of first oil leakage holes 3 on the sealing cover 2. In this state, the first oil leakage holes 3 and the second oil leakage holes 6 are communicated, and the lubricating oil between the shaft sleeve 1 and the bearing flows from the first oil leakage holes 3 to the second oil leakage holes 6 for leakage. After the collection of the lubricating oil is completed, the oil outlet plate 5 is rotated again so that the first oil leakage holes 3 and the second oil leakage holes 6 are misaligned with each other.

[0061] In this way, when it is necessary to collect the lubricating oil between the shaft sleeve 1 and the bearing, it is only necessary to rotate the oil outlet plate 5. After the collection is completed, it is only necessary to rotate the oil outlet plate 5 again to seal the first oil leakage holes 3 on the sealing cover 2 through the oil outlet plate 5, which is simple in operation and high in efficiency.

[0062] Referring to FIG. 1 and FIG. 3, specifically, the side of the sealing cover 2 away from the shaft sleeve 1 is extended and formed in the direction away from the shaft sleeve 1 into a ring-shaped folding 7, the bottom of the folding 7 is integrally formed in the horizontal direction with a rotating disc 8, the rotating disc 8 is coaxially connected with the folding 7, and the top of the rotating disc 8 is inwardly recessed in the direction away from the sealing cover 2 into a ring-shaped rotating groove 9. The side of the oil outlet plate 5 away from the sealing cover 2 is integrally formed along the circumferential side thereof with a ring-shaped rotating plug 10, the rotating plug 10 is inserted into the rotating groove 9 and can rotate in the rotating groove 9.

[0063] The oil outlet plate 5 and the sealing cover 2 are arranged in a rotatable installation mode by means of the rotating plug 10 and the rotating groove 9, and then the opening and closing of the first oil leakage holes 3 on the sealing cover 2 are realized by rotating the oil outlet plate 5.

[0064] Further, referring to FIG. 3 and FIG. 4, the side wall of the oil outlet plate 5 is integrally formed with a lever 11, which facilitates the rotation of the oil outlet plate 5, and is more convenient to use and better in experience.

[0065] Further, a sealing assembly is arranged between the oil outlet plate 5 and the sealing cover 2. Although the shaft sleeve 1 and the bearing are in normal working state, the oil outlet plate 5 and the sealing cover 2 are in close contact, and the first oil leakage hole 3 and the second oil leakage hole 6 are staggered with each other, so that the oil leakage phenomenon is almost impossible to occur. However, during the operation of the bearing, the oil outlet plate 5 and the sealing cover 2 will inevitably vibrate, which will cause a gap between the oil outlet plate 5 and the sealing cover 2, and the lubricating oil will leak from the first oil leakage hole 3 to the gap between the oil outlet plate 5 and the sealing cover 2, and then flow to the second oil leakage hole 6 from the gap between the oil outlet plate 5 and the sealing cover 2, or directly leak from the edge of the oil outlet plate 5.

[0066] The sealing assembly can seal the oil outlet plate 5 and the sealing cover 2, effectively preventing the lubricating oil from leaking.

[0067] Specifically, referring to FIGS. 3 and 4, the sealing assembly includes a sealing plate 12, which is in a whole "N" shape structure. The sealing plate 12 is installed below the oil outlet plate 5, and the left and right side plates of the sealing plate 12 are inserted on the oil outlet plate 5 through corresponding insertion plates. The two side plates and the bottom plate of the sealing plate 12 seal the oil outlet plate 5, thereby effectively preventing the lubricating oil from leaking from the oil outlet plate 5. When it is necessary to detect the lubricating oil, the sealing plate 12 can be removed from the oil outlet plate 5.

[0068] Referring to FIG. 3, the sealing assembly further includes a sealing groove 13 and a sealing ring 14. The sealing groove 13 is arranged along the bottom edge of the sealing cover 2, and the sealing ring 14 is integrally formed on the top of the oil outlet plate 5 along the circumferential side of the oil outlet plate 5, and is inserted into the sealing groove 13. The sealing groove 13 and the sealing ring 14 seal the circumferential side of the sealing cover 2 and the oil outlet plate 5, thereby effectively preventing the lubricating oil from leaking from the circumferential side of the sealing cover 2 and the oil outlet plate 5. At the same time, the sealing ring 14 and the sealing groove 13 guide the rotation of the oil outlet plate 5 during the rotation of the oil outlet plate 5, thereby facilitating the stability of the rotation of the oil outlet plate 5.

[0069] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Any equivalent changes made on the basis of the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
