Modes for Carrying Out the Invention

[0009] (First Embodiment) Hereinafter, with reference to the drawings, a spherical sliding bearing according to an embodiment of the present disclosure will be described. A plurality of spherical sliding bearings according to this embodiment are provided in a large building such as a building, a warehouse, a bridge, etc. In such a building, it is required to be able to identify each of the plurality of provided spherical sliding bearings and manage various information corresponding to each of the identified spherical sliding bearings without misidentification or forgery. The various information is, for example, information regarding the results of inspections on materials, dimensions, painting, and product performance performed on each component provided in a plurality of spherical sliding bearings. The product performance refers to, for example, the history characteristics of the horizontal load and horizontal displacement in the spherical sliding bearing. The product performance may include, for example, the friction coefficient of the spherical sliding bearing. To meet the above, the spherical sliding device according to this embodiment can identify each individual of the plurality of spherical sliding bearings. Also, various information corresponding to each individual of the spherical sliding bearing is stored in a browsable state, for example, in a folder created for each building on a server on the cloud (details will be described later).

[0010] (Spherical Sliding Bearing) FIG. 1 is a side view of a spherical sliding bearing 100 according to an embodiment. FIG. 2 is a first example of a plan view of a spherical sliding bearing 100 according to an embodiment. FIG. 3 is a second example of a plan view of a spherical sliding bearing 100 according to an embodiment. As shown in FIGS. 1, 2, and 3, the spherical sliding bearing 100 includes an upper plate 10, a lower plate 20, a sliding member 30, and an identification means 40. The spherical sliding bearing 100 is disposed between an upper structure U and a lower structure B. The upper plate 10 and the lower plate 20 slide with the sliding member 30 respectively. By this, the upper plate 10 and the lower plate 20 can move relative to each other in the horizontal direction. Thereby, the spherical sliding bearing 100 suppresses the vibration of the ground generated by an earthquake from propagating to the building. The spherical sliding bearing 100 according to this embodiment is a so-called double pendulum type spherical sliding bearing including the above-described respective components. In this embodiment, the upper structure U is, for example, a building. The lower structure B is, for example, the foundation structure of a building formed on the ground.

[0011] (Upper plate) The upper plate 10 is the part of the spherical sliding bearing 100 that is connected to the lower part of the upper structure U. The upper plate 10 is, for example, a plate-shaped member that is rectangular or square in plan view. Hereinafter, the upper surface, lower surface, and side surface of the upper plate 10 are referred to as the upper plate upper surface 11, the upper plate lower surface 12, and the upper plate side surface 13, respectively. The upper plate upper surface 11 faces the upper structure U. The upper plate upper surface 11 and the upper structure U are fixed, for example, by welding, bolt fastening, or the like. The upper plate lower surface 12 faces the lower structure B. An upper plate sliding surface 12s is provided on the upper plate lower surface 12. The upper plate sliding surface 12s is a depression provided on the upper plate lower surface 12. The upper plate sliding surface 12s has, for example, a cross-sectional arc shape (spherical surface) as shown in FIG. 1. The upper plate sliding surface 12s is formed in a circular shape in plan view as shown in FIG. 2 or FIG. 3. The upper plate sliding surface 12s slides with the sliding member 30. Thus, the upper plate 10 and the sliding member 30 can move relative to each other in the horizontal direction. At this time, in order to prevent the sliding member 30 from coming off the upper plate sliding surface 12s when the upper plate 10 and the sliding member 30 slide, it is preferable to provide a stopper ring S at the edge of the upper plate sliding surface 12s in plan view. The stopper ring S may be integrally formed with the upper plate 10, for example, by forming a wall portion 12w against which the sliding member 30 can abut between the upper plate lower surface 12 and the upper plate sliding surface 12s. Alternatively, the stopper ring S may be formed, for example, by attaching an annular member to the upper plate lower surface 12. The upper plate side surface 13 connects the upper plate upper surface 11 and the upper plate lower surface 12. The upper plate side surface 13 faces in the horizontal direction.

[0012] (Lower plate) The lower plate 20 has a configuration that is paired with the upper plate 10. That is, in this embodiment, the lower plate 20 is formed symmetrically with the upper plate 10. The lower platen 20 is the part of the spherical sliding bearing 100 that is connected to the upper part of the lower structure B. The lower platen 20 is, for example, a plate-shaped member that is rectangular or square in plan view. Hereinafter, the upper surface, lower surface, and side surface of the lower platen 20 are referred to as the lower platen upper surface 21, the lower platen lower surface 22, and the lower platen side surface 23, respectively. The lower platen upper surface 21 faces the upper structure U. A lower platen sliding surface 21s is provided on the lower platen upper surface 21. The lower platen sliding surface 21s is a depression provided on the lower platen upper surface 21. The lower platen sliding surface 21s has, for example, a cross-sectional arc shape (spherical surface) as shown in FIG. 1. The lower platen sliding surface 21s is formed in a circular shape in plan view as shown in FIG. 2 or FIG. 3. The lower platen sliding surface 21s slides with the sliding member 30. By this, the lower platen 20 and the sliding member 30 can move relative to each other in the horizontal direction. At this time, in order to prevent the sliding member 30 from coming off the lower platen sliding surface 21s when the lower platen 20 and the sliding member 30 slide, it is preferable that a stopper ring S is provided at the edge of the lower platen sliding surface 21s in plan view. The stopper ring S may be integrally formed with the lower platen 20, for example, by forming a wall portion 21w with which the sliding member 30 can come into contact between the lower platen upper surface 21 and the lower platen sliding surface 21s. Alternatively, the stopper ring S may be formed, for example, by attaching an annular member to the lower platen upper surface 21. The lower platen lower surface 22 faces the lower structure B. The lower platen lower surface 22 and the lower structure B are fixed to each other, for example, by welding or bolt fastening. The lower platen side surface 23 connects the lower platen upper surface 21 and the lower platen lower surface 22. The lower platen side surface 23 faces in the horizontal direction.

[0013] The upper platen 10 and the lower platen 20 are arranged such that their four sides overlap each other in plan view as shown in FIG. 2, for example. Alternatively, the upper platen 10 and the lower platen 20 may be arranged such that their four sides do not overlap each other in plan view as shown in FIG. 3, for example.

[0014] (Sliding member) The sliding member 30 is provided between the upper sheet 10 and the lower sheet 20. The sliding member 30 slides between the upper sheet 10 and the lower sheet 20. The sliding member 30 is, for example, a circular member in plan view. More specifically, the sliding member 30 is a substantially cylindrical member and is arranged such that its axis is along the vertical direction. The sliding member 30 includes an upper sliding surface 31 facing upward, a lower sliding surface 32 facing downward, and a sliding part side surface 33 connecting the upper sliding surface 31 and the lower sliding surface 32. The upper sliding surface 31 slides on the upper sheet 10. More specifically, the upper sliding surface 31 slides on the upper sheet sliding surface 12s of the upper sheet 10. Thus, the upper sheet 10 and the sliding member 30 can move relative to each other in the horizontal direction. The lower sliding surface 32 slides on the lower sheet 20. More specifically, the lower sliding surface 32 slides on the lower sheet sliding surface 21s of the lower sheet 20. Thus, the lower sheet 20 and the sliding member 30 can move relative to each other in the horizontal direction. As a result, the upper sheet 10 and the lower sheet 20 can move relative to each other in the horizontal direction. The sliding part side surface 33 is annularly located between the upper sliding surface 31 and the lower sliding surface 32. The sliding part side surface 33 faces in the horizontal direction.

[0015] (Identification means) FIG. 4 is a first view showing an example of the attachment of the identification means 40 to the spherical plain bearing 100. FIG. 5 is a second view showing an example of the attachment of the identification means 40 to the spherical plain bearing 100. The identification means 40 is provided to enable the identification of the spherical plain bearing 100. That is, it is provided to enable the identification of each individual of the plurality of spherical plain bearings 100 provided in a building. Alternatively, the identification means 40 may be able to individually identify any one of the components included in the spherical plain bearing 100. That is, the identification means 40 may be able to individually identify, among other things, each component of the upper sheet 10, the lower sheet 20, and the sliding member 30 of the spherical plain bearing 100. Identification means, for example, distinguishing one of the plurality of spherical plain bearings 100 from other spherical plain bearings 100.

[0016] The identification means 40 may be provided separately, for example, for identifying each individual of the spherical plain bearing 100 and for individually identifying each component included in the spherical plain bearing 100, or both the individuals of the spherical plain bearing 100 and each component included in the spherical plain bearing 100 may be identifiable by one identification means 40.

[0017] (Type of identification means) For the identification means 40, for example, barcodes, two-dimensional codes (so-called QR codes (registered trademarks)), RFID tags, IC tags, etc. are preferably used. Alternatively, the identification means 40 may be a character string such as a serial number. Any other means may be used for the identification means 40 as long as it can be read by a reading means 210 (described later).

[0018] The identification means 40 includes, for example, information regarding the address of a server 220 (described later). That is, by reading the identification means 40 with the reading means 210, it becomes possible to access the link destination to the server 220 in which data regarding various types of information is stored. Alternatively, the identification means 40 itself may indicate the above various types of information. That is, it may be possible to refer to the various types of information by reading the identification means 40.

[0019] (Installation method of the identification means 40) The identification means 40 is provided on the spherical plain bearing 100 by any of the following methods. The identification means 40 may be integrally provided on at least one of the upper plate 10, the lower plate 20, and the sliding member 30 of the spherical plain bearing 100, or may be provided separately from these and retrofitted.

[0020] When the identification means 40 is any of a barcode, a QR code (registered trademark), or a character string, the identification means 40 is provided on the spherical plain bearing 100 by attaching a sticker on which any of these is printed. Alternatively, the identification means 40 made of any of these may be provided on any of the components of the spherical plain bearing 100 by printing, engraving, or the like. When the identification means 40 is attached to the upper tray 10 or the lower tray 20 according to the above-described aspect, the identification means 40 is attached, for example, in the manufacturing process of the upper tray 10 or the lower tray 20, after the painting process and before being packaged. When the identification means 40 is attached to the sliding member 30 according to the above-described aspect, it is preferable that the identification means 40 be attached, for example, before the performance test. By doing so, the result of the performance test of the sliding member 30 can be stored in association with the identification means 40 corresponding to the individual of the sliding member 30.

[0021] When the identification means 40 is an RFID tag, the identification means 40 is provided on the spherical plain bearing 100 by attaching the RFID tag with an adhesive, a seal, or the like. Alternatively, the identification means 40 may be provided by manufacturing any of the components of the spherical plain bearing 100 with an RFID tag incorporated therein. When the identification means 40 is an RFID tag, it is preferable that a visible mark be provided at the location where the spherical plain bearing 100 is provided.

[0022] The identification means 40 in the present embodiment includes an anti-tampering seal 41. That is, when using a seal when providing the identification means 40 on the spherical plain bearing 100, it is preferable to use the anti-tampering seal 41. That is, the seal used for providing the identification means 40 on the spherical plain bearing 100 is preferably, for example, one that cannot be reattached and has an indication that it has been used once it is peeled off. The indication that it has been used may be, for example, that at least a part of the anti-tampering seal 41 remains on the spherical plain bearing 100 even after the seal is removed. Thereby, it can be visually confirmed that the identification means 40 attached in the manufacturing process has not been removed and another identification means 40 has not been attached. Therefore, it is possible to suppress the identification means 40 from being tampered with, such as being replaced with another object.

[0023] (Installation Location of Identification Means) In this embodiment, the identification means 40 is provided at any one of the following locations in the spherical plain bearing 100. That is, in one spherical plain bearing 100, the identification means 40 may be provided on only one or two of the upper plate 10, the lower plate 20, and the sliding member 30, or may be provided on all of them. The identification means 40 may be provided only one in the spherical plain bearing 100, or a plurality of them may be provided.

[0024] When the identification means 40 is provided on the upper plate 10, the identification means 40 is provided on, for example, the upper plate side surface 13. Here, as described above, when the upper plate 10 is square or rectangular in plan view, four planar upper plate side surfaces 13 are formed. At this time, the identification means 40 may be provided on only one to three of the four upper plate side surfaces 13, or may be provided on all four. Note that the upper plate 10 is not limited to a quadrangular shape in plan view, and may be hexagonal or octagonal. Alternatively, as shown in FIG. 2 or FIG. 3, the identification means 40 may be provided on the upper plate 10 at a portion of the lower surface 12 of the upper plate excluding the sliding surface 12s of the upper plate. At this time, the identification means 40 may be provided only one at a portion of the lower surface 12 of the upper plate excluding the sliding surface 12s of the upper plate, or a plurality of them may be provided.

[0025] When the identification means 40 is provided on the lower plate 20, the identification means 40 is provided on, for example, the lower plate side surface 23. The form when the identification means 40 is provided on the lower plate side surface 23 is the same as the case when the identification means 40 is provided on the upper plate side surface 13, and thus the description is omitted. Alternatively, as shown in FIG. 2 or FIG. 3, the identification means 40 may be provided on the lower plate 20 at a portion of the upper surface 21 of the lower plate excluding the sliding surface 21s of the lower plate. At this time, the identification means 40 may be provided only one at a portion of the upper surface 21 of the lower plate excluding the sliding surface 21s of the lower plate, or a plurality of them may be provided.

[0026] When the identification means 40 is provided on the sliding member 30, as shown in FIG. 5, the identification means 40 is provided on the side surface 33 of the sliding portion. At this time, only one identification means 40 may be provided on the side surface 33 of the sliding portion, or a plurality of identification means 40 may be provided. When a plurality of identification means 40 are provided on the side surface 33 of the sliding portion, the identification means 40 may be provided, for example, so as to be arranged in the vertical direction or so as to be arranged in the horizontal direction. When the identification means 40 is provided on the side surface 33 of the sliding portion, for example, in the spherical plain bearing 100, it is preferable that the identification means 40 is provided at a position where it can be visually recognized by looking through the sliding member 30 between the stopper rings S provided on each of the upper plate 10 and the lower plate 20.

[0027] (Shipping test system) Next, the shipping test system 200 according to the present embodiment will be described with reference to FIG. 6. FIG. 6 is a block diagram of the shipping test system 200 according to the embodiment. FIG. 7 is a schematic diagram of the biaxial shear test device 230. FIG. 8 is a displacement history curve of the spherical plain bearing 100 according to the test results of the biaxial shear test device 230. The shipping test system 200 is used to perform the shipping test of the spherical plain bearing 100 according to the above-described present embodiment. The shipping test system 200 includes a reading means 210, a server 220, a biaxial shear test device 230, and a spherical plain bearing 100.

[0028] (Reading means) The reading means 210 reads the identification means 40. The reading means 210 is, for example, a known barcode reader, a smartphone, a tablet PC, or the like. As described above, the identification means 40 includes, for example, information regarding the address of the server 220. In this case, by the reading means 210 reading the identification means 40, access to the server 220 becomes possible by a smartphone, a tablet PC, or the like. Alternatively, the identification means 40 itself indicates the above various types of information. In this case, by the reading means 210 reading the identification means 40, it becomes possible to refer to the various types of information using a smartphone, a tablet PC, or the like.

[0029] (Server) In response to the reading means 210 reading the identification means 40, the server 220 creates a folder corresponding to the spherical plain bearing 100 provided with the read identification means 40. Specifically, the server 220 first creates a qualified folder and a non - qualified folder. Also, the server 220 creates a property folder inside each of those folders. Further, the server 220 creates folders corresponding to the testing machine characteristic data, the test result data, etc. inside the property folder. In the qualified folder, information about the individuals of the spherical plain bearing 100 that passed the shipment test described later is stored. The non - qualified folder stores information about the individuals of the spherical plain bearing 100 that did not pass the shipment test described later. Information about each individual of the spherical plain bearing 100 that has undergone the shipment test is stored inside the property folders created in the qualified folder and the non - qualified folder respectively. At this time, the information about each individual of the spherical plain bearing 100 is sorted into folders and stored as the testing machine characteristic data which is the data of the testing machine that conducted the shipment test, and the test result data which is the data regarding the test results.

[0030] The server 220 includes a receiving unit 221, a storage processing unit 222, and a storage unit 223. The receiving unit 221 receives that the reading means 210 has read the identification means 40, and the information included in the identification means 40 read by the reading means 210. In response to receiving the above - mentioned content, the receiving unit 221 instructs the storage processing unit 222 described below to perform storage processing. The memory processing unit 222 performs memory processing in response to the reading means 210 reading the identification means 40. The memory processing is a process of creating a folder corresponding to the spherical plain bearing 100 provided with the identification means 40 read by the reading means 210 in the storage unit 223 in the server 220. The storage unit 223 is a part that stores various information in response to the memory processing of the memory processing unit 222.

[0031] In the folder created in the storage unit 223 of the server 220 by the above-described memory processing, for example, shipping test information indicating the results of the shipping test of the sliding member 30 is stored. In this way, the information corresponding to each individual spherical plain bearing 100 that can be identified by the identification means 40 can be managed in the folder created in the server 220 corresponding to each individual. Thereby, for example, compared with the case where an operator manually classifies and manages data, it is possible to prevent the occurrence of data misreading and forgery. Therefore, it is possible to suppress data misreading and forgery regarding various information.

[0032] (Biaxial Shear Test Apparatus) The biaxial shear test apparatus 230 performs a performance test of the spherical plain bearing 100 by reproducing the state where the spherical plain bearing 100 is provided in a building and the state when an earthquake occurs in the building part where the spherical plain bearing 100 is provided. Specifically, for example, the biaxial shear test apparatus 230 can apply a weight corresponding to a building to the spherical plain bearing 100 and apply a shear load in the horizontal direction. As shown in FIG. 7, the biaxial shear test apparatus 230 can attach a configuration corresponding to the upper platen 10 and the lower platen 20 of the spherical plain bearing 100. When performing a test on the spherical plain bearing 100, the sliding member 30 whose each individual can be identified by the above-described identification means 40 is disposed between the upper platen 10 and the lower platen 20 attached to the biaxial shear test apparatus 230. In this way, the spherical plain bearing 100 is formed in the biaxial shear test apparatus 230 and a test is performed. Specifically, first, using a biaxial shear test apparatus 230, a constant load corresponding to the weight of the building is applied to the spherical sliding bearing 100 in the vertical direction. Then, repeated loading is performed on the spherical sliding bearing 100 in the horizontal direction. By doing this, the history characteristics of the horizontal load and the horizontal displacement are measured. A graph showing the characteristics of the spherical sliding bearing 100 measured by the biaxial shear test apparatus 230 is shown in FIG. 8. In FIG. 8, the horizontal axis is the relative displacement amount in the horizontal direction between the upper plate and the lower plate in the spherical sliding bearing 100. In FIG. 8, the vertical axis is the value obtained by dividing the horizontal load by the vertical load. In the shipping test, it is confirmed that the value (friction coefficient) of the vertical axis in the state where the horizontal displacement in the graph shown in FIG. 8 is 0 mm is within the allowable value.

[0033] (Shipping Test Method for Spherical Sliding Bearings) Next, a shipping test method for the spherical sliding bearing 100 using the above-described shipping test system 200 will be described. The shipping test method according to the present embodiment includes a reading step and a creating step. In the present embodiment, the reading step and the creating step are performed for each of the spherical sliding bearings 100 provided in the building. In other words, the reading step and the creating step are repeated the same number of times as the number of the spherical sliding bearings 100 provided in the building.

[0034] (Reading Step) The reading step is a step of reading the identification means 40 using the reading means 210. That is, by an operator reading the identification means 40 provided on the spherical sliding bearing 100 with the reading means 210, the individual spherical sliding bearings 100 provided in the building are identified. By reading the identification means 40 in the reading step, the process proceeds to the creating step described below.

[0035] (Creating Step) The creation step is a step of creating a folder in which the spherical sliding bearing 100 or the shipping test information indicating the results of the shipping test of the sliding member 30 is stored in response to reading the identification means 40 in the reading step. Note that the results of the shipping tests of the upper cover 10 and the lower cover 20 may be stored in the folder created in the creation step. In the present embodiment, the folders created in the creation step include, for example, a pass folder corresponding to the fact that the upper cover 10, the lower cover 20, and the sliding member 30 have passed the shipping test, and a fail folder corresponding to the fact that the upper cover 10, the lower cover 20, and the sliding member 30 have failed the shipping test. This makes it possible to easily grasp the pass / fail of the shipping test system 200.

[0036] The shipping test is performed by the above-described procedure using, for example, a biaxial shear test apparatus 230 capable of applying a predetermined vertical load and a horizontal displacement. The aforementioned shipping test is performed on all of the spherical sliding bearings 100 installed in a single building. The results of the aforementioned shipping test are individually stored, for example, in a pass folder or a fail folder created in the storage unit 223 of the server 220. In this case, it is preferable that the information in the folder cannot be deleted, modified, or overwritten by setting detailed permissions. Alternatively, it is preferable that each individual spherical sliding bearing is automatically associated with the product performance test results corresponding to each individual, and the information is automatically stored in the folder. This preferably makes it impossible to change the information in the folder artificially, either intentionally or unconsciously. Alternatively, the information regarding the results of the shipping test may be included in the identification means 40 so as to be referable by reading the identification means 40.

[0037] Here, as described above, the reading step and the creation step are repeatedly performed multiple times. At this time, among the plurality of spherical sliding bearings 100 for one building, in the creation step performed first, it is preferable to create a property folder which is a folder corresponding to the building. And the folders corresponding to each of the plurality of spherical sliding bearings 100 are preferably created in the aforementioned property folder.

[0038] (Flow of shipping test) Next, with reference to FIG. 9, the flow of the shipping test of the spherical sliding bearing 100 according to the present embodiment will be described. FIG. 9 is a flowchart of the shipping test according to the embodiment. First, in the reading step, an operator reads the identification means 40 using the reading means 210 (step S1). At this time, the fact that the reading means 210 has read the identification means 40 and the information included in the identification means 40 read by the reading means 210 are transmitted to the receiving unit 221 of the server 220. At this time, if a property folder has been created in the storage unit 223 of the server 220 (step S2: YES), the process proceeds to the creation step (step S3). In the creation step (step S3), the storage processing unit 222 stores the test results corresponding to each of the plurality of spherical sliding bearings 100 inside the property folder created in the storage unit 223. The property folder is a project folder corresponding to the building where the plurality of spherical sliding bearings 100 are provided. Thus, the test results of each of the plurality of spherical sliding bearings 100 arranged in one building are stored in the folder created inside the property folder. In addition to the aforementioned test results, data of the members used in the manufacture of the spherical sliding bearing 100, data related to the manufacture, etc. may be stored in the property folder. The member data includes, for example, dimensions and material mill sheets. The data related to the manufacture includes, for example, data such as painting.

[0039] When the property folder has not been created in the storage unit 223 of the server 220 (step S2: NO), before transitioning to the creation step (step S3), the storage processing unit 222 creates a property folder in the storage unit 223 (step S4). Step S4 is executed, for example, when the shipping test of the first spherical plain bearing 100 is performed for a plurality of spherical plain bearings 100 arranged in one building.

[0040] And various information corresponding to each of the spherical plain bearings 100 is stored in the folder corresponding to each of the spherical plain bearings 100 (step S5). For example, when the identification means 40 includes information regarding the address of the server 220, in step S5, the above-mentioned various information corresponding to each of the plurality of spherical plain bearings 100 pre-stored in the storage unit 223 of the server 220 is stored in the property folder. Note that a folder corresponding to each individual of the spherical plain bearing 100 may be created inside the property folder, or information corresponding to each individual may be individually associated and stored in the folder corresponding to each individual of the spherical plain bearing 100. For example, when the identification means 40 itself indicates the above-mentioned various information, in step S5, the above-mentioned various information read from the identification means 40 is stored in association with the folder corresponding to each individual of the spherical plain bearing 100. By repeating the above flow for each of the plurality of spherical plain bearings 100, the shipping test according to the present embodiment is performed.

[0041] (Computer Configuration) FIG. 10 is a schematic block diagram showing the configuration of a computer 300 according to an embodiment. The computer 300 includes a processor 310, a main memory 320, and a storage 330. The above-described server 220 is implemented in the computer 300. The operations of each of the above-described components included in the server 220, that is, the receiving unit 221 and the storage processing unit 222, are stored in the storage 330 in the form of a program. The processor 310 reads the program from the storage 330 and expands it in the main memory 320, and executes the above processing according to the program. Further, the processor 310 secures a storage area corresponding to each of the above-described storage units 223 in the main memory 320 according to the program. Examples of the processor 310 include a CPU (Central Processing Unit), a GPU (Graphic Processing Unit), and a microprocessor.

[0042] The program may be for realizing a part of the functions to be exhibited by the computer 300. For example, the program may exhibit functions in combination with other programs already stored in the storage 330 or in combination with other programs implemented in other devices. In other embodiments, the computer 300 may include, in addition to or instead of the above configuration, a custom LSI (Large Scale Integrated Circuit) such as a PLD (Programmable Logic Device). Examples of the PLD include a PAL (Programmable Array Logic), a GAL (Generic Array Logic), a CPLD (Complex Programmable Logic Device), and an FPGA (Field Programmable Gate Array). In this case, some or all of the functions realized by the processor 310 may be realized by the integrated circuit. Such an integrated circuit is also included as an example of the processor 310.

[0043] Examples of the storage 330 include a magnetic disk, a magneto-optical disk, an optical disk, a semiconductor memory, and the like. The storage 330 may be an internal medium directly connected to the bus of the computer 300, or may be an external medium connected to the computer 300 via a communication line. Also, when this program is distributed to the computer 300 via a communication line, the computer 300 that has received the distribution may expand the program in the main memory 320 and execute the above processing. In at least one embodiment, the storage 330 is a non-transitory tangible storage medium. The functions of the storage unit 223 of the server 220 described above are realized by the storage 330 of the computer 300.

[0044] Also, the program may be for realizing a part of the functions described above. Further, the program may be a so-called difference file (difference program) that realizes the functions described above in combination with other programs already stored in the storage 330. Also, the server 220 may be implemented, for example, on the cloud.

[0045] As described above, according to the spherical plain bearing 100 according to the present embodiment, the spherical plain bearing 100 is provided with the identification means 40 capable of identifying each individual of the spherical plain bearing 100. Thereby, for example, it is possible to suppress the misidentification and forgery of various information corresponding to each individual of the spherical plain bearing 100. Specifically, for example, manufacturing information and the like for each individual of the spherical plain bearing 100 can be managed in association with each individual of the spherical plain bearing 100. That is, for example, the various information described above corresponding to each individual of the spherical plain bearing 100 can be stored in and accessed from a folder corresponding to each individual of the spherical plain bearing 100 on the cloud.

[0046] Further, the identification means 40 is provided on the sliding member 30. Thereby, for example, among the spherical plain bearings 100, it is possible to suppress the misidentification and forgery of various information corresponding to each individual of the sliding member 30 in particular. Specifically, for example, the results of the shipping tests and the like performed for each individual of the sliding member 30 can be managed in association with each individual of the sliding member 30. That is, for example, the various information described above corresponding to each individual of the sliding member 30 can be stored in and accessed from a folder corresponding to each individual of the sliding member 30 on the cloud.

[0047] Further, the identification means 40 is provided on the sliding part side surface 33 that connects the upper sliding surface 31 and the lower sliding surface 32 of the sliding member 30. Thereby, for example, the position of the identification means 40 can be easily confirmed by visually observing the sliding member 30 from between the upper plate 10 and the lower plate 20. Also, for example, compared with the case where the identification means 40 is provided on the upper sliding surface 31 or the lower sliding surface 32 of the sliding member 30, it is possible to prevent the friction coefficient of each sliding surface from being affected.

[0048] Further, the identification means 40 is provided on a portion of the upper surface of the lower plate 20 excluding the lower plate sliding surface 21s. Thereby, the operator can easily confirm the position of the identification means 40 by visually observing the upper surface of the lower plate 20. Therefore, the operator can grasp the position of the identification means 40 while the spherical plain bearing 100 is installed at the site. Also, for example, compared with the case where the identification means 40 is provided on the lower plate sliding surface 21s, in addition to preventing the friction coefficient of the lower plate sliding surface 21s from being affected, the identification means 40 can be made difficult to be damaged.

[0049] Further, the identification means 40 is provided on a portion of the lower surface of the upper plate 10 excluding the upper plate sliding surface 12s. Thereby, the operator can easily confirm the position of the identification means 40 by visually observing the lower surface of the upper plate 10. Therefore, the operator can grasp the position of the identification means 40 while the spherical plain bearing 100 is installed at the site. In addition, for example, in addition to preventing the friction coefficient of the upper cover sliding surface 12s from being affected as compared with the case where the identification means 40 is provided on the upper cover sliding surface 12s, the identification means 40 can be made difficult to be soiled.

[0050] Also, a plurality of identification means 40 are provided. Thereby, it is possible to make it easier for the operator to find the identification means 40. Therefore, the work of checking the identification means 40 can be efficiently performed.

[0051] Also, the identification means 40 includes an anti-tampering seal 41. Thereby, it is possible to make the identification means 40 difficult to be tampered with. Therefore, it is possible to more reliably suppress the misidentification and tampering of various information corresponding to each individual of the spherical sliding bearing 100.

[0052] Also, the identification means 40 can identify the sliding member 30. Thereby, it is possible to suppress the misidentification and tampering of various information corresponding to each individual of the sliding member 30, particularly in the spherical sliding bearing 100. Specifically, for example, the results of the shipping tests performed for each individual of the sliding member 30 can be managed in association with each individual of the sliding member 30. That is, for example, the various information described above corresponding to each individual of the sliding member 30 can be stored in and accessed from a folder corresponding to each individual of the sliding member 30 on the cloud.

[0053] Also, according to the shipping test method according to the present embodiment, first, the identification means 40 is read in the reading step. Then, in response to reading the identification means 40 in the reading step, a folder in which shipping test information indicating the results of the shipping test of the sliding member 30 is stored is created in the creation step. By this, for each of the spherical sliding bearings 100 identified by the identification means 40, a corresponding folder can be surely created. Therefore, it is possible to suppress the misidentification and tampering of various information corresponding to each individual of the spherical sliding bearing 100. That is, for example, the results of the shipping tests of the sliding members 30 provided in each individual of the spherical sliding bearing 100 can be surely stored in the corresponding folder.

[0054] Further, according to the shipping test system 200 according to the present embodiment, first, the reading means 210 reads the identification means 40. Then, in response to the reading means 210 reading the identification means 40, the server 220 creates a folder in which shipping test information indicating the result of the shipping test of the sliding member 30 is stored. By this, for each of the spherical plain bearings 100 identified by the identification means 40, a corresponding folder can be surely created. Therefore, it is possible to suppress the misidentification and forgery of various information corresponding to each individual of the spherical plain bearing 100. That is, for example, the result of the shipping test of the sliding member 30 provided in each individual of the spherical plain bearing 100 can be surely stored in the corresponding folder.

[0055] (Second Embodiment) Next, the spherical plain bearing 100 according to the second embodiment of the present disclosure will be described with reference to FIGS. 11 and 12. In this second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted, and only the differences will be described.

[0056] The spherical plain bearing 100 according to the second embodiment is different from the first embodiment in that it is a so-called single pendulum type spherical plain bearing. Examples of the single pendulum type spherical plain bearing 100 include, for example, those shown in FIGS. 11 and 12.

[0057] FIG. 11 is a first example of the single pendulum type spherical plain bearing 100. The spherical sliding bearing 100 shown in Fig. 11 has a curvature of the sliding surface between the lower plate 20 and the sliding member 30, that is, the lower sliding surface 32, which is larger than the curvature of the sliding surface between the upper plate 10 and the sliding member 30, that is, the upper sliding surface 31. Due to this, the sliding member 30 rotates about the center of curvature of the lower plate sliding surface 21s of the lower plate 20 as the rotation center. Therefore, in the spherical sliding bearing 100 shown in Fig. 11, the lower plate 20 and the sliding member 30 do not move relative to each other in the horizontal direction. Since the lower plate 20 is connected to the upper part of the lower structure B and does not move in the horizontal direction, in the spherical sliding bearing 100 shown in Fig. 11, the sliding member 30 does not move in the horizontal direction. And only the upper plate 10 is displaced in the horizontal direction. In the spherical sliding bearing 100 shown in Fig. 11, the identification means 40 is preferably attached to, for example, the sliding part side surface 33 of the sliding member 30. Alternatively, the identification means 40 may be attached to any part of the spherical sliding bearing 100 as in the first embodiment.

[0058] Fig. 12 shows a second example of the spherical sliding bearing 100 of the single pendulum type. In the spherical sliding bearing 100 shown in Fig. 12, the curvature of the sliding surface between the upper plate 10 and the sliding member 30, that is, the upper sliding surface 31, is larger than the curvature of the sliding surface between the lower plate 20 and the sliding member 30, that is, the lower sliding surface 32. Due to this, the sliding member 30 rotates about the center of curvature of the upper plate sliding surface 12s of the upper plate 10 as the rotation center. Therefore, in the spherical sliding bearing 100 shown in Fig. 12, the upper plate 10 and the sliding member 30 do not move relative to each other in the horizontal direction. The spherical sliding bearing 100 shown in Fig. 12 is different from the first example of the spherical sliding bearing 100 shown in Fig. 11 in that the sliding member 30 moves in the horizontal direction as the upper plate 10 moves in the horizontal direction. In the spherical sliding bearing 100 shown in Fig. 12, the identification means 40 is preferably attached to, for example, the sliding part side surface 33 of the sliding member 30. Alternatively, the identification means 40 may be attached to any part of the spherical sliding bearing 100 as in the first embodiment.

[0059] Note that the technical scope of the present disclosure is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present disclosure. For example, the spherical sliding bearing 100 may be a so-called triple pendulum type spherical sliding bearing.

[0060] In addition, within the scope not departing from the spirit of the present disclosure, it is possible to appropriately replace the components in the above-described embodiment with well-known components, and the above-described modified examples may also be appropriately combined.
