[0040] <<Bearing cover 31>> The bearing cover 31 is a member that can be installed on the end of the boss portion 13 . FIG. 10 is a view of the bearing device 10 as seen from the BB cross section. The bearing cover 31 is attached so as to be adjacent to a surface of the bearing 42 that is perpendicular to the axial direction. Specifically, the bearing cover 31 is attached to the load side of the rotating shaft 41 indicated by the arrow E in FIG.

[0041] FIG. 11 is a view of the bearing cover 31 as seen from the BB cross section. As shown in FIG. 11, the bearing cover 31 is formed in an annular shape so that the rotary shaft 41 can be passed through it. The bearing cover 31 is provided with a boss corresponding portion 33 and an installation groove 32 . As shown in FIG. 5, the bearing cover 31 is provided with a bearing cover-side replacement hole 12a (replacement hole 12).

[0042] The boss portion corresponding portion 33 is provided so that the bearing cover 31 can be installed on the end of the boss portion 13 that supports the bearing 42. The boss portion corresponding portion 33 is an annular convex portion formed so as to be able to fit into the inner periphery of the boss portion 13 . The boss portion corresponding portion 33 is a convex portion formed so that when the boss portion corresponding portion 33 is fitted onto the inner periphery of the boss portion 13, the boss portion corresponding portion 33 comes into surface contact with the outer ring 42b of the bearing 42.

[0043] The installation groove 32 is a groove formed in the bearing cover 31 so as to be located inside the inner periphery of the boss portion 13 when the bearing cover 31 is attached to the boss portion 13 . The installation groove 32 is an annular groove into which the lubricant container 21 is fitted. FIG. 12 is a partially enlarged view of the BB cross section of the bearing cover 31. As shown in FIG. 12, the installation groove 32 is formed by a first groove 32a and a second groove 32b.

[0044] The first groove 32a is an annular recess formed in the bearing cover 31 for fitting the connecting portion 22 of the lubricant container 21 therein. The width of the first groove 32a is w10. The width of the first groove 32a is the length of the first groove 32a in the vertical direction in FIG. The depth of the first groove 32a is d1. The depth of the first groove 32a is the length of the first groove 32a in the left-right direction in FIG. The depth d1 of the first groove 32a is desirably equal to or greater than the width w6 of the connecting portion 22. This allows the connecting portion 22 to be stably fitted into the first groove 32a.

[0045] The second groove 32b is a recess formed in the bearing cover 31 in an annular shape, into which the receiving portion 23 of the lubricant container 21 is fitted. By forming the second groove 32b, the annular bearing cover 31 is provided with a housing support portion . The width of the second groove 32b is w11. The width of the second groove 32b is the length of the second groove 32b in the vertical direction in FIG. The depth of the second groove 32b is d2. The depth of the first groove 32a is the length of the second groove 32b in the left-right direction in FIG. The depth d2 of the second groove 32b is desirably less than the width w7 of the housing portion 23. This prevents the housing portion support portion 34 from hitting the bearing 42 when the bearing cover 31 is installed on the boss portion 13. This prevents friction between the bearing cover 31 and the bearing 42.

[0046] FIG. 13 is a conceptual diagram of the bearing device 10 as seen from the front, with a partial enlargement of the installation groove 32 and the lubricant container 21. As shown in FIG. 13, the lubricant container 21 can be fitted into the installation groove 32. Specifically, the first groove connecting portion 22a fits into the first groove 32a, and the accommodating portion 23 fits into the second groove 32b, so that the accommodating portion 23 can be installed on the bearing cover 31 so that it is arranged in a circular ring shape. The width w10 of the first groove 32a is greater than the height t1 of the connecting portion 22. The width w11 of the second groove 32b is equal to or greater than the height t2 of the accommodation portion . Because the accommodation portion 23 and the connecting portion 22 are in contact with each other at a width w5, the portion of the connecting portion 22 at width w5 does not deform and remains flat. Therefore, the width w11 of the second groove 32b is set to a width w10 that is large enough for a flat plate with height t1 and width w5 to slide. When the lubricant container 21 is fitted into the installation groove 32, a regular polygon is formed by the lower base of the trapezoidal shape of the opening. When there are 12 storage sections 23, a regular dodecagon is formed. By making the interior angles on both sides of the lower base of the trapezoidal opening half the interior angles of a regular polygon, a regular polygon is formed with the upper base of the trapezoidal opening. Since the interior angles of a regular dodecagon are 150 degrees, if the interior angles on both sides of the lower base of the trapezoidal opening are 75 degrees, the upper bases of the trapezoidal opening will be continuous and a regular dodecagon will be formed with the upper bases. As a result, adjacent storage portions 23 are arranged in a ring shape without any gaps. The interior angles on both sides of the lower base of the trapezoidal shape of the opening may be less than half the interior angles of a regular polygon.

[0047] As shown in FIG. 5, the bearing cover side replacement hole 12a is a through hole provided in the bearing cover 31 for inserting and removing the lubricant container 21 into and from the inner space of the installation groove 32. The bearing cover side replacement hole 12 a is a through hole that communicates with the inner space of the installation groove 32 and passes through the inside and outside of the bearing cover 31 . The bearing cover-side replacement hole 12a is provided so as to form the replacement hole 12 integrally with the boss-side replacement hole 12b of the boss 13 when the bearing cover 31 is installed on the end of the boss 13. In other words, the replacement hole 12 is provided across the bearing cover 31 and the boss 13. It is desirable that the shape of the replacement hole 12 matches the shape of the AA cross section of the lubricant container 21, as shown in FIG. The replacement hole 12 is provided so as to communicate with an installation groove 32 at the bottom of a bearing cover 31 installed on the boss portion 13 . The entrance of the exchange hole 12 is called an exchange opening 12c.

[0048] FIG. 14 is a side view of the bearing device 10 as viewed from the C direction. As shown in FIG. 14, the bearing device 10 may include a replacement port cover 12d for covering the replacement port 12c.

[0049] The manner in which the lubricant 25 is supplied from the lubricant supply device 30 to the bearing 42 will now be described. FIG. 15 is a conceptual diagram showing the bearing device 10 in which the lubricant supply device 30 is installed on the boss portion 13, as viewed from the front. As shown in FIG. 15, the connecting portion 22 is fitted into the installation groove 32 of the bearing cover 31 in a deformed state, so that the plurality of accommodating portions 23 are arranged in a circular ring shape. Here, the storage section 23 disposed at one end of the connecting section 22 is attached so as to be in contact with the connecting section 22 at a width w4, so that the handle section 24 does not overlap the connecting section 22. The lubricant container 21 is installed so that the accommodating portions 23 disposed at both ends of the connecting portion 22 are located below the bearing device 10. Therefore, the container 23 containing the lubricant 25 is disposed on the top side of the bearing device 10. Therefore, the sensor 26 is installed so as to be disposed at the bottom of the bearing device 10.

[0050] FIG. 16 is a view of the bearing device 10 in which the lubricant supply device 30 is installed on the boss portion 13, as viewed from the BB cross section. 16, the lubricant supplying device 30 is installed so that the opening of the accommodation portion 23 is adjacent to a plane perpendicular to the axial direction of the bearing 42. However, if the accommodation portion 23 and the inner ring 42c of the bearing 42 come into contact with each other, friction will occur. Therefore, it is desirable that the installed lubricant supply device 30 has the bearing adjacent portion 22b of the connecting portion 22 come into contact with the outer ring 42b of the bearing 42 so that the opening of the accommodating portion 23 does not come into complete contact with the bearing 42.

[0051] In response to the vibration of the rotary shaft 41, the lubricant supplying device 30 supplies the lubricant 25 from the opening of the accommodating portion 23 to the rolling elements 42a. Specifically, the lubricant 25 of the lubricant supply device 30 is placed on the top side of the bearing device 10, and falls downward by gravity while lubricating the bearing 42.

[0052] FIG. 17 is a conceptual diagram showing how the lubricant 25 drops downward when the bearing device 10 in which the lubricant supply device 30 is installed on the boss portion 13 is viewed from the front. 17, the lubricant 25 in the storage section 23 installed on the top side of the bearing device 10 drops over time to the position of the storage section 23 at the bottom of the bearing device 10. In other words, the lubricant 25 that passes through the bearing 42 and falls to the bottom accumulates over time in the storage section 23 located at the bottom of the bearing device 10.

[0053] As the lubricant 25 accumulates in the lower storage portion 23, the pressure in the lower storage portion 23 increases. A sensor 26 installed in the lower housing 23 detects an increase in pressure in the lower housing 23 . When the sensor 26 detects a pressure equal to or greater than the threshold, it sends a signal to the control panel 1 indicating that it is recommended to replace the lubricant container 21.

[0054] ***Installation method of lubricant container 21 according to the first embodiment*** A method for installing the lubricant container 21 will be described below. FIG. 18 is a conceptual diagram of the lubricant container 21 in the middle of being stored, as viewed from the front of the bearing device 10. As shown in FIG. 18, when the lubricant container 21 is installed in the bearing device 10, it is inserted through the replacement opening 12c. The lubricant container 21 passes through the replacement hole 12, and the storage section 23 containing the lubricant 25 is disposed on the top side of the bearing device 10. The storage section 23 in which the sensor 26 is installed is disposed on the bottom of the bearing device 10.

[0055] FIG. 19 is a flowchart showing an example of a method for installing the lubricant container 21. A method for installing the lubricant container 21 will be specifically described with reference to FIG. The installation method of the lubricant container 21 shown in FIG. 19 is based on the assumption that the lubricant container 21 due for replacement is removed from the bearing device 10 and a new lubricant container 21 is installed in the bearing device 10.

[0056] In step S11, the replacement port cover 12d provided on the replacement port 12c of the bearing device 10 is removed. After step S11, the process proceeds to step S12.

[0057] In step S12, the handle 24 of the lubricant container 21 is pulled from the replacement opening 12c. The lubricant container 21 is removed from the bearing device 10 by pulling the handle portion 24. After step S12, the process proceeds to step S13.

[0058] In step S13, a new lubricant container 21 is inserted into the bearing device 10. The end of the lubricant container 21 opposite to the handle portion 24 is inserted into the replacement opening 12c. The lubricant container 21 is inserted through the replacement hole 12 which is a through hole provided in the bearing cover 31 . Then, the handle portion 24 is pushed toward the replacement hole 12 . By doing so, the lubricant container 21 can be fitted into the installation groove 32, which is an annular groove provided in the bearing cover 31, and installed so that the lubricant container 21 goes around the installation groove 32 once. In addition, since the lead wire of the sensor 26 is arranged along the bearing adjacent portion 22b of the lubricant container 21 toward the handle portion 24, the lead wire of the sensor 26 also makes one turn along the installation groove 32 together. After step S13, the process proceeds to step S14.

[0059] In step S14, the sensor 26 is wired. After the lubricant container 21 is installed in the bearing device 10, one end of the wiring of the sensor 26 is in a state where it protrudes from the replacement port 12c. Connect the wiring of the sensor 26 to the control panel 1. After step S14, the process proceeds to step S15.

[0060] In step S15, the replacement port cover 12d is fitted onto the replacement port 12c. In step S15, the installation of the lubricant container 21 on the bearing device 10 is completed.

[0061] ***Method for manufacturing the lubricant container 21 according to the first embodiment*** A method for manufacturing the lubricant container 21 will now be described. FIG. 20 is a flowchart showing an example of a method for manufacturing the lubricant container 21 according to the first embodiment.

[0062] In step S21, a plurality of containers 23 for containing lubricants 25 are connected by deformable connecting portions 22. Specifically, the storage portion 23 and the connecting portion 22 are bonded together with an adhesive. After step S21, the process proceeds to step S22.

[0063] In step S22, the handle portion 24 is attached to one end of the plurality of storage portions 23 connected by the connecting portion 22. Specifically, the handle portion 24 is adhered to one end of the connecting portion 22 with an adhesive. The length of the handle portion 24 is preferably such that when the lubricant supply device 30 is attached inside the hoisting machine 2, it does not protrude from the replacement opening 12c. After step S22, the process proceeds to step S23.

[0064] In step S23, the sensor 26 is installed inside the container 23. Specifically, the sensor 26 is adhered with an adhesive to the center of the surface of the housing portion 23 that is in surface contact with the connecting portion 22 . Then, the wiring of the sensor 26 is fixed along the bearing adjacent portion 22b toward the handle portion 24. In step S23, the manufacturing of the lubricant container 21 is completed.

[0065] ***Summary of the first embodiment*** The outline of the first embodiment will be summarized below. In embodiment 1, a lubricant supply device 30 was described that includes a lubricant container 21 made of an oil-resistant and heat-resistant elastic material, and a bearing cover 31 having an installation groove 32 that serves as a guide for guiding the lubricant container 21 to the vicinity of the rolling element 42a. The lubricant container 21 has a deformable connecting portion 22 and a storage portion 23, and is inserted into and removed from the replacement hole 12 provided on the side surface of the bearing device 10. The inserted lubricant container 21 fits into a circumferential groove-shaped installation groove 32 provided inside the bearing cover 31, thereby forming a cylindrical shape that fits along the cylindrical wall of the boss portion 13 of the bearing device 10. This allows lubricant oil from the grease that is the lubricant 25 contained in the accommodation portion 23 to be supplied to the rolling elements 42a, protecting the bearing 42. Initially, the lubricant 25 is filled only in the upper housing portion 23 of the bearing device 10, and over time, it lubricates the bearing 42 and accumulates by gravity in the lower housing portion 23. The lower housing portion 23 is equipped with a sensor 26, which issues a warning to the outside when a certain amount of lubricant 25 has accumulated in the lower housing portion 23. When replacing the lubricant container 21, the handle 24 of the lubricant container 21 located near the replacement hole 12 is pulled out, and the lubricant 25 inside the bearing device 10 is discharged.

[0066] ***Effects of the First Embodiment*** As described above, the lubricant container 21 of embodiment 1 has a deformable connecting portion 22, so that the lubricant container 21 can be inserted through the replacement hole 12 of the bearing device 10 and installed along the installation groove 32 of the bearing cover 31. In other words, the lubricant container 21 can be easily installed without removing the bearing cover 31 attached to the bearing device 10.

[0067] Furthermore, the lubricant container 21 of the first embodiment can be removed from the bearing device 10 by pulling the handle portion 24 through the replacement hole 12. That is, the lubricant container 21 to be replaced can be taken out without removing the bearing cover 31 attached to the bearing device 10.

[0068] In addition, in the lubricant container 21 of embodiment 1 installed in the bearing device 10, the lubricant 25 (e.g., overgrease or dead grease) that has been supplied to the bearing 42 and is no longer needed accumulates in the empty storage section 23 of the lubricant container 21. Therefore, when replacing the lubricant container 21, the lubricant container 21 to be replaced is removed, and the lubricant 25 that is no longer needed can also be removed from the bearing device 10. In other words, the effort required to replace the lubricant container 21 can be reduced. Furthermore, since the unnecessary lubricant 25 accumulates in the empty storage portion 23, the lubricant 25 is less likely to accumulate inside the bearing cover 31, thereby improving the performance of the bearing 42 and extending its lifespan.

[0069] Furthermore, since the replacement hole 12 of the bearing device 10 is smaller than the diameter of the mounting portion of the bearing cover 31, the area that needs to be protected when replacing the lubricant container 21 can be reduced.

[0070] Furthermore, the sensor 26 provided in the lubricant container 21 issues an alarm when it is time to replace the lubricant container 21, so that the unnecessary lubricant 25 can be prevented from spilling into the bearing cover 31. This eliminates the need for space to store unnecessary lubricant 25 inside the bearing cover 31 or the bearing device 10, allowing the volume of the bearing cover 31 or the bearing device 10 to be reduced.

[0071] Furthermore, depending on the setting of the threshold value of the sensor 26, a warning is issued that it is time to replace the lubricant container 21, so that the lubricant container 21 can be replaced before the lubricant 25 for the bearing 42 runs out. Furthermore, there is no longer a need to fill the lubricant container 21 with a large amount of lubricant 25 as a measure to prevent the bearing 42 from running out of lubricant, and the bearing device 10 can be made smaller.

[0072] Furthermore, by attaching a lid 27 to the storage section 23 of the lubricant container 21, it is possible to prevent oil from scattering around and foreign matter from getting mixed in during transportation and operation.

[0073] Furthermore, in the hoisting machine 2 of the first embodiment, the replacement work of the lubricant container 21 can be performed with less labor and more efficiently, so that the service downtime of the elevator 100 can be reduced.

[0074] ***Supplement to the first embodiment*** The following is a supplement to the first embodiment. <About Elevator 100> In this embodiment, the elevator 100 is assumed to have a machine room. The hoist 2 is installed in the middle of the main ropes 4 so that the car 3 and the counterweight 5 rise and fall in opposite directions. The roping system of the elevator 100 is 1:1 roping. However, the elevator 100 does not have to have a machine room. Furthermore, the elevator 100 may use a system such as 2:1 roping instead of 1:1 roping. In the elevator 100 without a machine room, one end of the main rope 4 may be fixed to the ceiling of the elevator shaft. In other words, the installation position of the hoisting machine 2 may be anywhere as long as the car 3 can be raised and lowered by the main ropes 4.

[0075] <About Hoist 2> In the present embodiment, the hoisting machine 2 is provided with the bearing device 10 and the bearing device 10a, but the hoisting machine 2 may be provided with only the bearing device 10. The hoisting machine 2 may include three or more bearing devices 10.

[0076] <Regarding the bearing device 10> In this embodiment, the bearing device 10 has a lubricant supply device 30 attached to one side of the bearing 42 (the load side of the rotating shaft 41) and a lubricant supply device 30a attached to the other side of the bearing 42 (the anti-load side of the rotating shaft 41). However, the bearing device 10 may be configured so that the lubricant supply device 30 is provided on only one side of the bearing 42. In other words, one or two lubricant supply devices 30 may be provided for one bearing 42.

[0077] <About the lubricant container 21> The lubricant container 21 may be installed in a bearing cover 31 that does not have a replacement hole 12. In this case, it is necessary to remove the bearing cover 31 when replacing the lubricant container 21. However, because the lubricant container 21 is strip-shaped, it is easier to remove and replace the lubricant container 21 than a ring-shaped container.

[0078] The number of the storage sections 23 may be any number as long as it is plural. However, since the receiving portions 23 are arranged in an annular shape with respect to a plane perpendicular to the axial direction of the bearing 42, it is desirable to have five or more receiving portions 23.

[0079] In the present embodiment, the plurality of storage sections 23 are connected by the connecting section 22 so that the lower bases of the storage sections 23 are continuous, but the present invention is not limited to this. A plurality of storage sections 23 may be connected by connecting sections 22 so that the bottom bottoms of the storage sections 23 do not come into contact with each other.

[0080] In this embodiment, the housing portion 23 has a trapezoidal shape when viewed from the opening side, but the shape is not limited to this. The storage section 23 may be triangular when viewed from the opening side. In this case, the base side of the triangle is attached to the surface of the connecting section 22. The receiving portion 23 may be fan-shaped when viewed from the opening side. In this case, the arc portion of the fan shape is attached to the surface of the connecting portion 22.

[0081] The lubricant container 21 does not necessarily have to include the sensor 26 .

[0082] The lubricant container 21 does not necessarily have to include the handle portion 24 . Moreover, the connecting portion 22 may be formed longer to provide a handle portion 24.

[0083] The length of the handle portion 24 may be shorter than the length that allows the handle portion 24 to reach the replacement opening 12c when the lubricant container 21 is installed on the bearing cover 31. In this case, when removing the lubricant supply device 30 from the bearing cover 31, the handle portion 24 can be pulled using a tool.

[0084] The handle portion 24 may have the same hardness as the connecting portion 22 or may have a different hardness. If the handle portion 24 is harder than the connecting portion 22, the lubricant container 21 can be easily pushed into the replacement hole 12 when installing the lubricant container 21 in the bearing cover 31.

[0085] In this embodiment, the connecting portion 22 and the containing portion 23 of the lubricant container 21 may be bonded by welding, double-sided tape, a button, or the like.

[0086] <About bearing cover 31> The replacement hole 12 may be formed only in the bearing cover 31 . Specifically, when the width w1 of the boss portion 13 and the width w2 of the bearing 42 are the same, the replacement hole 12 only needs to be the bearing cover-side replacement hole 12a.

[0087] The bearing cover 31 may be integral with the boss portion 13 .

[0088] The installation groove 32 may be configured to include only the first groove 32a. However, the bearing cover 31 needs a space such as the second groove 32b so that the accommodation portion 23 can be disposed therein. For example, if there is space to place the accommodating portion 23, the inner diameter of the cylindrical shape of the bearing cover 31 may be increased so that the second groove 32b is not formed inside the first groove 32a shown in FIG.

[0089] ***Modification of the First Embodiment*** A modification of the first embodiment will be described below. <About the lubricant container 21> In this embodiment, the storage section 23 of the lubricant container 21 is a container having a recess for storing the lubricant 25, and the storage section 23 is arranged so as to be in surface contact with the surface of the connecting section 22, but this is not limited to this. FIG. 21 shows an example of a modified example of the lubricant container 21. As shown in the front view of the lubricant container 21 in FIG. 21, the container 23 does not have to be a container. As shown in the AA cross-sectional view of the lubricant container 21 in FIG. 22, it is only necessary that the containing portion 23 and the connecting portion 22 form a recess for containing the lubricant 25. The storage section 23 may be structured as a pocket provided on the surface of the connecting section 22 .

[0090] In this embodiment, the connecting portion 22 of the lubricant container 21 is strip-shaped, but the present invention is not limited to this. The connecting portion 22 does not have to be strip-shaped, and may be present between the receiving portions 23 . FIG. 23 shows an example of a modified lubricant container 21 in which the connecting portion 22 is not strip-shaped. 23, a rim is formed at the lower portion of the storage portion 23. A deformable connecting portion 22 connects the rims of the storage portion 23 together. FIG. 24 is a cross-sectional view of the lubricant container 21 shown in FIG. 23 taken along the line AA. In FIG. 24, the width w12 of the lower part of the accommodation portion 23 is the same as the width w6 of the connection portion 22. Therefore, when the lubricant container 21 shown in Figures 23 and 24 is installed on the bearing cover 31, the edge opposite the opening of the storage section 23 and the first groove connection section 22a of the connecting section 22 fit into the first groove 32a. The lubricant container 21 shown in FIGS. 23 and 24 can accommodate bearings 42 of various sizes by changing the number of storage portions 23 and connecting portions 22.

[0091] FIG. 25 shows an example of a modified lubricant container 21 in which the connecting portion 22 is not strip-shaped. In FIG. 25, the connecting portion 22 connects the side surfaces of the storage portion 23 together. FIG. 26 is a cross-sectional view of the lubricant container 21 of FIG. 25 taken along the line AA. As shown in FIG. 26, the width w7 of the accommodation portion 23 is the same as the width w7 of the accommodation portion 23 shown in FIG. 8. Furthermore, the width w6 of the connecting portion 22 shown in FIG. 26 is the same as the width w6 of the connecting portion 22 shown in FIG. The lubricant container 21 shown in FIGS. 25 and 26 can accommodate bearings 42 of various sizes by changing the number of containing portions 23 and connecting portions 22.

[0092] In this embodiment, the storage section 23 arranged at one end of the connecting section 22 is attached to the connecting section 22 so that the width w4 of contact with the connecting section 22 is half the width w5 of contact between the other storage section 23 and the connecting section 22, but is not limited to this. In the connecting portion 22 of FIG. 7, the accommodating portion 23 disposed at one end of the connecting portion 22 may be attached so as to be in surface contact with the surface of the connecting portion 22 across a width w5. However, it is desirable that the end of connecting portion 22 be cut diagonally so that the height t1 of connecting portion 22 gradually decreases toward the end of connecting portion 22 and so that the back surface of connecting portion 22 approaches the front surface of connecting portion 22. Specifically, the end of the connecting portion 22 is preferably formed at an angle so that the rear end of the connecting portion 22 bends toward the surface of the end of the connecting portion 22 over a length of width w4 or more and width w5 or less. By doing so, even if the handle portion 24 overlaps the connecting portion 22 when the lubricant container 21 is installed on the bearing cover 31, the containing portions 23 are arranged in an annular shape.

[0093] In this embodiment, the sensor 26 is a pressure sensor, but is not limited to this. The sensor 26 may be a photoelectric sensor. In this case, the sensor 26 detects by light such as infrared light that the lubricant 25 has accumulated in the container 23 to a certain amount or more. The sensor 26 may be a strain sensor. In this case, the sensor 26 detects that the lubricant 25 accumulates in the container 23 to a certain extent, causing the container 23 to expand and become distorted.

[0094] <Regarding the lubricant supply device 30> In this embodiment, the lubricant supply device 30 is provided in the bearing device 10, and the bearing device 10 is provided in the hoisting machine 2, but the lubricant supply device 30 may also be provided in a structure having a rotating shaft 41 other than the hoisting machine 2. For example, rotating electrical machines including generators, motors, fans, water pumps, and centrifugal compressors, casters, wheel hubs, and opening and closing devices.
