[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 As shown, the high-temperature resistant metal bearing includes a disc-shaped bearing body 1, and also includes a lower snap-fit ​​seat 2, an upper snap-fit ​​seat 3 and a fastener. After the upper snap-fit ​​seat 3 and the lower snap-fit ​​seat 2 are snap-fitted and connected by the fastener, the upper snap-fit ​​seat 3 and the lower snap-fit ​​seat 2 form a cylindrical cooling cylinder, and the bearing body 1 is positioned and connected in the cooling cylinder, and the cooling cylinder has a storage structure for storing high-temperature resistant lubricating grease.

[0026] like Figure 1 and Figure 2 and Figure 3 As shown, the upper portion of the lower snap-fit ​​seat 2 has a positioning recess 2a that is recessed and matches the lower side of the bearing body 1, and the lower portion of the upper snap-fit ​​seat 3 has a positioning recess 3a that is recessed and matches the upper side of the bearing body 1. The lower side of the above-mentioned bearing body 1 is embedded in the positioning recess 2a, and the upper side of the above-mentioned bearing body 1 is embedded in the positioning recess 3a.

[0027] The upper snap-fit ​​seat 3 and the lower snap-fit ​​seat 2 are connected by fasteners, which makes the entire bearing easy to install and remove. In other words, the cooling cylinder formed by the connection between the upper snap-fit ​​seat 3 and the lower snap-fit ​​seat 2 covers the bearing body 1. This not only provides appropriate protection for the bearing body 1, but also ensures that the storage structure in the cooling cylinder always contains an appropriate amount of high-temperature resistant grease. Under the action of the high-temperature resistant grease, the bearing body 1 can be stably lubricated, effectively improving the stability of the high-temperature resistant metal bearing.

[0028] The first positioning recess 2a and the second positioning recess 3a both match the outer side of the bearing. Such a structure enables the bearing body 1 to be stably positioned in the cooling cylinder.

[0029] The lower buckle seat 2 also has a recessed positioning groove 2b at the positioning recess 1 2a, and the upper buckle seat 3 also has a recessed positioning groove 2 3d at the positioning recess 2 3a. The two sides of the above-mentioned bearing body 1 are respectively embedded in the positioning groove 1 2b and the positioning groove 2 3d.

[0030] The width of the first positioning groove 2b and the width of the second positioning groove 3d match the width of the bearing body 1. Such a structure can stably position the bearing body 1 in the cooling cylinder.

[0031] The storage structure includes an arc-shaped protruding retaining edge 3c at the outer end of the positioning recess 2a of the lower buckle seat 2, and a storage cavity for storing high-temperature resistant lubricating grease is formed between the retaining edge 3c and the bearing body 1.

[0032] Such a structure can stably store high-temperature resistant lubricating grease in the cooling cylinder.

[0033] The retaining edge 3c and the lower buckle seat 2 are an integrated structure.

[0034] The outer side of the bearing body 1 has an annular recessed oil groove 1a, the middle part of the positioning groove 1 2b has a recessed oil groove 2b1, and the middle part of the positioning groove 2 3d has a recessed oil groove 3b. The above-mentioned oil groove 2b1 is opposite to and connected with the lower part of the oil groove 1 1a, and the above-mentioned oil groove 3b is opposite to and connected with the upper part of the oil groove 1 1a.

[0035] In this embodiment, the bearing body has a through oil hole 6, the outer end of the oil hole is connected to the oil groove 1a, and the inner end of the oil hole is located on the inner side of the outer ring of the bearing body. Such a structure can introduce high-temperature resistant lubricating grease into between the outer ring and the inner ring of the bearing body.

[0036] The oil groove 1 a, the oil groove 2 b1 and the oil groove 3 b are all connected. Such a structure enables the high-temperature resistant lubricating grease to stably enter and exit the outer side of the bearing body 1 .

[0037] The lower portion of the lower buckle seat 2 has a concave storage recess 5 , which is located at the bottom of the storage cavity 4 .

[0038] The lower buckle seat 2 also has a connecting channel connecting the storage recess 5 with the second oil tank 2b1.

[0039] The storage recess 5 can store more high-temperature resistant lubricating grease, and the connecting channel can allow the high-temperature resistant lubricating grease to enter the above-mentioned oil grooves more stably.

[0040] A sealing gasket is provided at the connection between the upper buckle seat 3 and the lower buckle seat 2 .

[0041] Under the action of the sealing gasket, the sealing performance of the connection between the upper buckle seat 3 and the lower buckle seat 2 can be effectively improved.

[0042] The lower portion of the lower buckle seat 2 has a connecting portion for contacting the surface of a frame or a bracket.

[0043] The setting of the connection part can effectively improve the stability of the entire high-temperature resistant metal bearing when connected to the bracket or the frame.

[0044] Since the high-temperature resistant lubricating grease can be stably stored in the storage cavity between the lower buckle seat and the bearing body, this high-temperature resistant metal bearing can ensure that there is always an appropriate amount of high-temperature resistant lubricating grease on the bearing body. The bearing can be stably lubricated during frequent and long-term operations, ensuring that the high-temperature resistant metal bearing can operate normally in a high-temperature operating environment, and its stability is relatively high.

[0045] At the same time, the storage structure for storing high-temperature resistant lubricating grease is located inside the lower buckle seat, so it does not take up too much space. Its structure is also relatively compact and has high practical value.

[0046] The various technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention.
