Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to a motor end cover, a vertical motor and a drive system. Background Technology

[0002] A vertical motor is a type of motor whose output shaft is perpendicular to the chassis or transmission mechanism. Its mounting holes are equidistantly distributed around the output shaft. It features a compact structure and high load-bearing capacity, and is widely used in industrial production for mechanical equipment such as vertical water pumps and vertical lathes. Due to varying installation site conditions, the vibration of a vertical motor after installation cannot be predicted. However, users have strict requirements regarding the vibration value of the vertical motor after installation, ensuring that the vibration does not exceed the standard value.

[0003] Currently, if a vertical motor vibrates excessively after installation, technicians need to conduct on-site testing and diagnosis. The problem of excessive vibration can be solved by modifying the installation support structure of the vertical motor or by returning the vertical motor to the factory for modification.

[0004] However, sending technicians to the site for testing and diagnosis, modifying and installing the support structure, and returning the vertical motor to the factory for modification all require a long time and a lot of money, resulting in low efficiency and high cost in solving the vibration problem of the vertical motor. Utility Model Content

[0005] In view of this, the motor end cover, vertical motor and drive system provided by this utility model can improve the repair efficiency of vertical motor vibration problems and reduce the repair cost of vertical motor vibration problems.

[0006] According to a first aspect of the present invention, a motor end cover is provided for use in a vertical motor. The motor end cover includes: a first flange, a second flange, a connecting sleeve, and a plurality of reinforcing ribs; a first end of the connecting sleeve is connected to the first flange, and a second end of the connecting sleeve is connected to the second flange, the first flange and the second flange are parallel, and the axis of the connecting sleeve is perpendicular to the first flange; the first flange is configured to be connected to the housing of the vertical motor, and the second flange is configured to be connected to a load; the plurality of reinforcing ribs are arranged circumferentially along the connecting sleeve, and the reinforcing ribs are respectively connected to the outer side wall of the first flange, the second flange, and the connecting sleeve; at least a portion of the free edges of the reinforcing ribs are provided with vibration absorption grooves, the free edges being the edges of the reinforcing ribs not connected to the first flange, the second flange, and the connecting sleeve; the areas of the reinforcing ribs located on both sides of the vibration absorption grooves are respectively provided with first through holes, the first through holes being used to detachably connect the reinforcing ribs and two webs located on both sides of the reinforcing ribs, and after the two webs are connected to the reinforcing ribs, the vibration absorption grooves are located between the two webs.

[0007] In one possible implementation, each of the reinforcing ribs is provided with at least one of the vibration-absorbing grooves.

[0008] In one possible implementation, the angle between the extending direction of the vibration absorption groove and the axial direction of the connecting sleeve is greater than 0 degrees and less than 90 degrees.

[0009] In one possible implementation, the angle between the extending direction of the vibration absorption groove and the axial direction of the connecting sleeve is equal to 45 degrees.

[0010] In one possible implementation, the depth of the vibration absorption groove along its extension direction is less than or equal to half the size of the reinforcing rib.

[0011] In one possible implementation, the width of the vibration absorption groove is less than or equal to the thickness of the reinforcing rib in a direction perpendicular to the extension direction of the vibration absorption groove.

[0012] In one possible implementation, the first flange is provided with a second through hole for the output shaft of the vertical motor to pass through, the diameter of the second through hole being smaller than the inner diameter of the connecting sleeve; the second flange is provided with a third through hole, the diameter of the third through hole being equal to the outer diameter of the connecting sleeve, and the second end of the connecting sleeve being located inside the third through hole.

[0013] In one possible implementation, the reinforcing rib is a pentagonal flat plate structure, with its first to fifth sides sequentially adjacent, the first side connected to the fifth side, the first side parallel to the third side, the second side parallel to the fourth side, the first side perpendicular to the second side, and the length of the fourth side less than the length of the second side; the first side of the reinforcing rib is connected to the first flange, the second side of the reinforcing rib is connected to the outer wall of the connecting sleeve, and the third side of the reinforcing rib is connected to the second flange; the fifth side of the reinforcing rib is the free side, and the extension direction of the vibration absorption groove is perpendicular to the fifth side.

[0014] According to a second aspect of the present invention, a vertical motor is provided, including the motor end cover provided in the first aspect or any possible implementation thereof.

[0015] According to a third aspect of the present invention, a drive system is provided, comprising: a load and a vertical motor provided in the second aspect above; the vertical motor is located above the load, the load is connected to a second flange included in the motor end cover of the vertical motor, and a rotating component included in the load is connected to the output shaft of the vertical motor; the vertical motor is used to drive the rotating component to rotate.

[0016] As can be seen from the above technical solution, the first end of the connecting sleeve is connected to the first flange for connecting the housing, and the second end of the connecting sleeve is connected to the second flange for connecting the load. Multiple reinforcing ribs are arranged circumferentially along the connecting sleeve, and the reinforcing ribs are respectively connected to the first flange, the second flange, and the connecting sleeve. At least some of the reinforcing ribs are provided with vibration absorption grooves, and the web plate is detachably connected to the reinforcing ribs. After removing the web plate from the reinforcing ribs, the groove width of the vibration absorption groove can change slightly when the vertical motor vibrates, reducing the stiffness of the reinforcing ribs, which can absorb the vibration of the vertical motor. After connecting the web plate to the reinforcing ribs, the groove width of the vibration absorption groove will not change when the vertical motor vibrates under the support of the web plate, increasing the stiffness of the reinforcing ribs. When the vertical motor vibrates excessively, by disassembling or installing the web plate and adjusting the stiffness of the motor end cover, the overall resonance frequency of the vertical motor, load, and motor end cover after connection is different from the rotation frequency of the vertical motor, thereby avoiding resonance during the operation of the vertical motor and solving the problem of excessive vibration during the operation of the vertical motor. Compared to modifying the support structure in the load or returning the vertical motor to the factory for modification, the problem of excessive vibration in vertical motors can be quickly solved by disassembling or installing the web plate. This can improve the efficiency of solving vertical motor vibration problems and reduce the cost of solving them. Attached Figure Description

Detailed Implementation

[0029] As mentioned earlier, vertical motors are typically mounted above the load and connected to the load's supporting structure via motor end caps. After manufacturing, the vertical motor is transported to the site for installation. Because installation sites vary, the vibration of the vertical motor after installation cannot be predicted during manufacturing. After installation, excessive vibration may occur due to resonance, but on-site personnel cannot resolve this by adjusting the stiffness of the system formed by the motor and load. Therefore, on-site testing and diagnosis by technicians are required, followed by modification of the supporting structure or returning the motor to the factory for modification to address the excessive vibration. However, on-site testing and diagnosis, support structure modification, and motor return for modification all require significant time and expense, resulting in low efficiency and high cost in resolving vertical motor vibration issues.

[0030] In this embodiment of the invention, the motor end cover includes a first flange, a second flange, a connecting sleeve connecting the first flange and the second flange, and multiple reinforcing ribs. The first flange can be connected to the housing of the vertical motor, and the second flange can be connected to the load, thereby allowing the vertical motor to be mounted on the load via the motor end cover. The reinforcing ribs are provided with vibration absorption grooves, and the vibration absorption grooves are equipped with detachably connected web plates. Connecting the web plates of the vibration absorption grooves to the reinforcing ribs increases the stiffness of the reinforcing ribs; removing the web plates reduces the stiffness of the reinforcing ribs. After mounting the vertical motor onto the load via the motor end cover, removing at least part of the web plates of the vibration absorption grooves according to the vibration of the vertical motor allows for multi-level adjustment of the motor end cover stiffness, preventing excessive motor vibration due to resonance. Since the web plate can be easily installed and removed on-site, the problem of excessive vibration of the vertical motor can be solved by simply removing and installing the web plate. There is no need for professional technicians to come to the site for testing and diagnosis, nor is there any need to modify the support structure or send the vertical motor back to the factory for modification. This can improve the efficiency of solving the problem of vertical motor vibration and reduce the cost of solving the problem of vertical motor vibration.

[0031] The motor end cover, vertical motor, and drive system provided in the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Figure 1 This is a schematic diagram of the motor end cover 10 according to one embodiment of the present invention. Figure 1As shown, the motor end cover 10 includes a first flange 11, a second flange 12, a connecting sleeve 13, and multiple reinforcing ribs 14. The first end of the connecting sleeve 13 is connected to the first flange 11, and the second end of the connecting sleeve 13 is connected to the second flange 12. The first flange 11 and the second flange 12 are parallel, and the axis of the connecting sleeve 13 is perpendicular to both the first flange 11 and the second flange 12. The first flange 11 can be connected to the housing of the vertical motor, and the second flange 12 can be connected to the load.

[0033] Both the first flange 11 and the second flange 12 are circular plate structures, and both are provided with through holes for the output shaft of the vertical motor to pass through. In one example, the connecting sleeve 13 is a circular tubular structure, and the axis of the through holes for the output shaft in the first flange 11 and the second flange 12 coincides with the axis of the connecting sleeve 13. In one example, the first flange 11, the second flange 12, and the connecting sleeve 13 are all made of steel, and the first flange 11 and the connecting sleeve 13 can be connected by welding, as can the second flange 12 and the connecting sleeve 13.

[0034] The first flange 11 has multiple first mounting holes. Bolts passing through these holes connect to the housing of the vertical motor, thus connecting the first flange 11 to the housing. The second flange 12 has multiple second mounting holes. Bolts passing through these holes connect to the load, thus connecting the second flange 12 to the load. It should be noted that the load typically includes a support structure. The second flange 12 is bolted to the support structure, which vertically supports the vertical motor. The load also includes rotating components, such as impellers or gears. These rotating components are connected to the output shaft of the vertical motor, and the rotation of the motor's output shaft drives the rotating components to rotate.

[0035] Multiple reinforcing ribs 14 are connected circumferentially along the connecting sleeve 13, and the reinforcing ribs 14 are respectively connected to the first flange 11, the second flange 12, and the outer wall of the connecting sleeve 13. Because the vertical motor is heavy and generates significant torque during operation, simply connecting the first flange 11 and the second flange 12 via the connecting sleeve 13 may not be strong enough to support the weight and torque of the vertical motor. By providing multiple reinforcing ribs 14, the overall strength and rigidity of the motor end cover 10 can be improved, ensuring that the motor end cover 10 can support the weight of the vertical motor and withstand the torque generated during its operation.

[0036] In one example, the reinforcing rib 14 is a plate-like structure, parallel to the axis of the connecting sleeve 13, that is, perpendicular to the first flange 11 and the second flange 12. Multiple reinforcing ribs 14 are evenly arranged along the circumference of the connecting sleeve 13; the number of reinforcing ribs 14 can be 6, 8, or 12, etc. The reinforcing ribs 14 can be connected to the first flange 11, the second flange 12, and the connecting sleeve 13 by welding. The reinforcing ribs 14 can be made of steel.

[0037] At least some of the free edges of the reinforcing rib 14 are provided with vibration absorption grooves 141. The free edges are the edges where the reinforcing rib 14 is located at the junction of the first flange 11, the second flange 12, and the connecting sleeve 13. When the motor end cover 10 supports a vertical motor, the reinforcing rib 14 bears compressive stress.

[0038] like Figure 1 As shown, the reinforcing rib 14 is provided with first through holes 142 on both sides of the vibration absorption groove 141. The first through holes 142 are used to detachably connect the reinforcing rib 14 and the two web plates 15 located on both sides of the reinforcing rib 14. After the two web plates 15 are connected to the reinforcing rib 14, the vibration absorption groove 141 is located between the two web plates 15.

[0039] When the web plate 15 is removed from the reinforcing rib 14, that is, when the vibration absorption groove 141 is not sandwiched between the two web plates 15, the vertical motor generates vibration during operation. The groove width of the vibration absorption groove 141 will change slightly to absorb the vibration of the vertical motor, while making the stiffness of the reinforcing rib 14 smaller.

[0040] When the two web plates 15 are connected to the reinforcing ribs 14, i.e., the vibration absorption groove 141 is sandwiched between the two web plates 15, the web plates 15 are connected to the areas of the reinforcing ribs 14 on both sides of the vibration absorption groove 141 through the first through hole 142. The web plates 15 can strengthen the reinforcing ribs 14 at the vibration absorption groove 141. When the vertical motor is connected to the load through the motor end cover 10, the vertical motor generates vibration during operation. Under the support of the web plates 15, the groove width of the vibration absorption groove 141 will not change, making the reinforcing ribs 14 have greater rigidity.

[0041] After connecting the vertical motor to the load via the motor end cover 10, if the vertical motor vibrates excessively during operation, a web plate 15 can be connected to the reinforcing rib 14 to increase the overall rigidity of the motor end cover 10, or one or more web plates 15 can be removed from the reinforcing rib 14 to reduce the overall rigidity of the motor end cover 10. This ensures that the overall resonance frequency of the vertical motor, load, and motor end cover 10 after connection is different from the rotation frequency of the vertical motor, thereby preventing resonance during the operation of the vertical motor and solving the problem of excessive vibration during the operation of the vertical motor.

[0042] In one example, after connecting the vertical motor and the load through the motor end cover 10, the two web plates 15 of each vibration absorption groove 141 are connected to the corresponding reinforcing rib plate 14. Then, the vertical motor is powered on and made to run. If the vibration during the operation of the vertical motor does not meet the requirements, one or more web plates 15 of the vibration absorption groove 141 are removed, and the vertical motor is made to run again. Depending on the vibration during the operation of the vertical motor, the web plates 15 are removed or installed until the vibration during the operation of the vertical motor meets the requirements.

[0043] The web 15 can be connected to the reinforcing rib 14 by mating bolts and nuts. In one example, such as Figure 1 As shown, the reinforcing rib 14 has two first through holes 142 on each side of the vibration absorption groove 141, and each web 15 has four third through holes, with the four first through holes 142 and the four third through holes positioned opposite each other. When connecting the web 15 to the reinforcing rib 14, bolts pass through the third through holes on one web 15, the first through holes 142 on the reinforcing rib 14, and the third through holes on the other web 15 in sequence, and then engage with nuts. Thus, a pair of webs 15 can be connected to the reinforcing rib 14 using four bolts and four nuts. The webs 15 increase the stiffness of the area where the vibration absorption groove 141 is located on the reinforcing rib 14.

[0044] The web 15 has a flat plate structure; for example, the web 15 can be a rounded rectangular steel plate. After the web 15 is connected to the reinforcing rib 14, one side of the web 15 fits against one side of the reinforcing rib 14, that is, the web 15 is parallel to the reinforcing rib 14. It should be noted that the web 15 needs to have a certain thickness and strength to ensure that it will not bend or deform under the pressure of the vertical motor, thereby ensuring that the width of the vibration absorption groove 141 does not change.

[0045] In this embodiment of the invention, the first end of the connecting sleeve 13 is connected to the first flange 11 for connecting the housing, and the second end of the connecting sleeve 13 is connected to the second flange 12 for connecting the load. Multiple reinforcing ribs 14 are arranged circumferentially along the connecting sleeve 13, and the reinforcing ribs 14 are respectively connected to the first flange 11, the second flange 12, and the connecting sleeve 13. At least some of the reinforcing ribs 14 are provided with vibration absorption grooves 141, and the web plate 15 is detachably connected to the reinforcing ribs 14. After removing the web plate 15 from the reinforcing ribs 14, the groove width of the vibration absorption groove 141 can change slightly when the vertical motor vibrates, reducing the stiffness of the reinforcing rib 14, thus absorbing the vibration of the vertical motor. After connecting the web plate 15 to the reinforcing ribs 14, the groove width of the vibration absorption groove 141 will not change when the vertical motor vibrates under the support of the web plate 15, thus increasing the stiffness of the reinforcing rib 14. When the vertical motor vibrates excessively, the stiffness of the motor end cover 10 can be adjusted by disassembling or installing the web plate 15. This ensures that the overall resonant frequency of the vertical motor, load, and motor end cover 10 is different from the rotational frequency of the vertical motor, thus preventing resonance during operation and resolving the problem of excessive vibration. Compared to modifying the support structure in the load or returning the vertical motor to the factory for modification, disassembling or installing the web plate 15 can quickly resolve the problem of excessive vertical motor vibration, thereby improving the efficiency and reducing the cost of solving the vertical motor vibration problem.

[0046] In one possible implementation, each reinforcing rib 14 is provided with at least one vibration absorption groove 141.

[0047] Figure 2 A schematic diagram of a reinforcing rib 14 according to an embodiment of the present invention is shown. Figure 2 As shown, the reinforcing rib 14 is provided with a vibration absorption groove 141. Figure 3 A schematic diagram of a reinforcing rib 14 according to another embodiment of the present invention is shown. Figure 3 As shown, the reinforcing rib 14 is provided with two vibration absorption grooves 141. In other embodiments, the reinforcing rib 14 may be provided with a greater number of vibration absorption grooves 141, such as three, four or more vibration absorption grooves 141.

[0048] When the reinforcing rib 14 is provided with multiple vibration absorption grooves 141, the multiple vibration absorption grooves 141 can be arranged in parallel, or at least some of the vibration absorption grooves 141 are not parallel.

[0049] In this embodiment of the utility model, each reinforcing rib 14 is provided with a vibration absorption groove 141, and each reinforcing rib 14 can be provided with one or more vibration absorption grooves 141. Each vibration absorption groove 141 has a matching web plate 15. By disassembling and assembling the web plate 15, the stiffness of the reinforcing rib 14 can be adjusted in multiple stages, increasing the adjustment range of the stiffness of the reinforcing rib 14. This ensures that the overall resonance frequency of the vertical motor, load and motor end cover 10 after connection can be adjusted to be different from the rotation frequency of the vertical motor, thereby avoiding resonance during the operation of the vertical motor and improving the applicability of the motor end cover 10.

[0050] In one possible implementation, such as Figure 4 The schematic diagram of the reinforcing rib 14 and the connecting sleeve 13 shown shows that the angle θ between the extension direction of the vibration absorption groove 141 and the axial direction of the connecting sleeve 13 is greater than 0° and less than 90°.

[0051] In this embodiment of the present invention, when the vertical motor vibrates during operation, it will generate tensile stress and / or compressive stress on the reinforcing rib 14. The angle θ between the extension direction of the vibration absorption groove 141 and the axis of the connecting sleeve 13 is greater than 0° and less than 90°. When the vertical motor applies tensile stress to the reinforcing rib 14, the groove width of the vibration absorption groove 141 can be increased slightly. When the vertical motor applies compressive stress to the reinforcing rib 14, the groove width of the vibration absorption groove 141 can be decreased slightly. Thus, regardless of whether the vertical motor applies tensile stress or compressive stress to the reinforcing rib 14, the reinforcing rib 14 can undergo slight elastic deformation, thereby ensuring that the vibration absorption groove 141 can absorb the vibration of the vertical motor.

[0052] In one possible implementation, the angle θ between the extending direction of the vibration absorption groove 141 and the axial direction of the connecting sleeve 13 is equal to 45°.

[0053] In this embodiment of the utility model, the angle θ between the extension direction of the vibration absorption groove 141 and the axial direction of the connecting sleeve 13 is 45°. When the vertical motor applies tensile stress and compressive stress to the reinforcing rib 14, the reinforcing rib 14 is relatively easy to undergo elastic deformation, thereby ensuring the ability of the vibration absorption groove 141 to absorb the vibration of the vertical motor.

[0054] In one possible implementation, such as Figure 5 The schematic diagram of the reinforcing rib 14 shown shows that, along the extension direction of the vibration absorption groove 141, the depth h of the vibration absorption groove 141 is less than or equal to 1 / 2 of the dimension H of the reinforcing rib 14, that is, h≤H / 2.

[0055] In this embodiment of the invention, the reinforcing rib 14 is used to enhance the load-bearing capacity of the motor end cover 10, ensuring that the motor end cover 10 can support the vertical motor, bear the weight of the vertical motor, and withstand the torque generated during the operation of the vertical motor. Providing a vibration absorption groove 141 on the reinforcing rib 14 reduces the strength of the reinforcing rib 14. The depth h of the vibration absorption groove 141 is less than or equal to half the width H of the reinforcing rib 14 along the extending direction of the vibration absorption groove 141. This ensures that the vibration absorption groove 141 can effectively absorb the vibration of the vertical motor while ensuring that the reinforcing rib 14 has sufficient strength so that the motor end cover 10 can reliably support the vertical motor, and that the reinforcing rib 14 will not crack at the root of the vibration absorption groove 141.

[0056] In one possible implementation, such as Figure 6 The schematic diagram of the reinforcing rib 14 shown shows that, along the direction perpendicular to the extension direction of the vibration absorption groove 141, the width d of the vibration absorption groove 141 is less than or equal to the thickness D of the reinforcing rib 14.

[0057] In this embodiment of the utility model, since the reinforcing rib 14 has great strength, the width of the vibration absorption groove 141 changes only slightly when the vertical motor vibrates. The width d of the vibration absorption groove 141 is set to be less than or equal to the thickness D of the reinforcing rib 14. While ensuring that the vibration absorption groove 141 can absorb the vibration of the vertical motor, the reinforcing rib 14 still has sufficient strength. This avoids the reinforcing rib 14 from undergoing plastic deformation under compressive stress or pressure due to excessive width of the vibration absorption groove 141, thereby ensuring the stability and reliability of the motor end cover 10 in supporting the vertical motor.

[0058] In one possible implementation, such as Figure 7 The schematic diagram of the motor end cover 10 shows that the first flange 11 has a second through hole 111 for the output shaft of the vertical motor to pass through. The diameter of the second through hole 111 is smaller than the inner diameter of the connecting sleeve 13. The bottom surface of the first flange 11 is connected to the first end of the connecting sleeve 13. The second flange 12 has a third through hole 121. The diameter of the third through hole 121 is equal to the outer diameter of the connecting sleeve 13. The second end of the connecting sleeve 13 is located inside the third through hole 121, and the wall of the third through hole 121 is connected to the outer wall of the connecting sleeve 13.

[0059] In one example, the second end of the connecting sleeve 13 is flush with the bottom surface of the second flange 12, and the wall of the third through hole 121 is connected to the outer wall of the connecting sleeve 13 by welding. The bottom surface of the first flange 11 is connected to the first end of the connecting sleeve 13 by welding.

[0060] The diameter of the first flange 11 is larger than the outer diameter of the connecting sleeve 13. After the first flange 11 is connected to the connecting sleeve 13, the edge area of ​​the first flange 11 forms an outer eave, which facilitates the connection between the reinforcing rib 14 and the first flange 11.

[0061] In one example, the side wall of the connecting sleeve 13 is provided with an oil injection hole and an observation window. Lubricating oil can be added to the load through the oil injection hole, and the output shaft of the vertical motor and the rotating parts connected to the output shaft can be observed through the observation window.

[0062] In this embodiment of the invention, the first flange 11 is provided with a second through hole 111 for the output shaft of the vertical motor to pass through. The diameter of the second through hole 111 is smaller than the inner diameter of the connecting sleeve 13, and the outer diameter of the first flange 11 is larger than the outer diameter of the connecting sleeve 13. This ensures that the first flange 11 can be stably connected to the connecting sleeve 13. The first flange 11 extending beyond the outer edge of the connecting sleeve 13 provides a connection position for the reinforcing rib 14, ensuring the firmness of the connection between the first flange 11 and the reinforcing rib 14. The second flange 12 is provided with a third through hole 121. The second end of the connecting sleeve 13 is located inside the third through hole 121, and the wall of the third through hole 121 is connected to the outer wall of the connecting sleeve 13, ensuring the stability of the connection between the connecting sleeve 13 and the second flange 12. Since the second end of the connecting sleeve 13 is located inside the third through hole 121, lubricating oil can be added to the load through the oil injection hole provided on the side wall of the connecting sleeve 13, and the operating status of the load can be observed through the observation window provided on the side wall of the connecting sleeve 13, facilitating load maintenance.

[0063] In one possible implementation, such as Figure 8 The schematic diagram of the reinforcing rib 14 shown indicates that the reinforcing rib 14 is a pentagonal flat plate structure. The first side 147 to the fifth side 146 of the reinforcing rib 14 are adjacent to each other, and the first side 147 and the fifth side 146 are connected. The first side 147 is parallel to the third side 144, the second side 143 is parallel to the fourth side 145, the first side 147 is perpendicular to the second side 143, and the length of the fourth side 145 is less than the length of the second side 143.

[0064] like Figure 1 and Figure 8 As shown, the first side 147 of the reinforcing rib 14 is connected to the first flange 11, the second side 143 of the reinforcing rib 14 is connected to the outer wall of the connecting sleeve 13, and the third side 144 of the reinforcing rib 14 is connected to the second flange 12. The fifth side 146 of the reinforcing rib 14 is a free side, that is, the vibration absorption groove 141 is provided on the fifth side 146, and the extending direction of the vibration absorption groove 141 is perpendicular to the fifth side 146.

[0065] It should be noted that in some other embodiments, the reinforcing rib 14 can be a quadrilateral flat plate structure, and... Figure 8Compared to the pentagonal reinforcing rib 14 shown, the quadrilateral reinforcing rib 14 does not include the fourth side 145, and the third side 144 is connected to the fifth side 146.
