Description

Technical Field

[0001] The present disclosure relates to the technical field of bearing maintenance equipment, and in particular to a bearing adapter sleeve disassembly tool. Background Art

[0002] Vertical water pumps are characterized by simple structure, high stability, and strong conveying capacity. However, during maintenance and repair of vertical water pumps, bearing removal can be difficult due to the bearing adapter sleeve located inside the bearing, which prevents the push screw in the bearing seat from directly ejecting the bearing.

[0003] In the related art, the bearing is usually removed by directly destroying the bearing. However, destroying the bearing is time-consuming and labor-intensive, which affects the maintenance period. Utility Model Content

[0004] The purpose of the present disclosure is to provide a bearing adapter sleeve removal tool to solve the above problems.

[0005] To achieve the above-mentioned object, the present disclosure provides a bearing adapter sleeve removal tool, comprising a sleeve, wherein the outer diameter of the sleeve is smaller than the inner diameter of the bearing, the sleeve comprising a first end and a second end opposite to each other, the first end being provided with a force-bearing portion for being struck by a striking tool, the second end having an opening for a shaft to extend into the sleeve, the end surface of the second end being configured to abut against the end surface of a bearing adapter sleeve sleeved on the shaft;

[0006] The projection of the force-bearing portion along the axial direction of the sleeve covers the projection of the sleeve along the axial direction of the sleeve, and the projection area of the force-bearing portion along the axial direction of the sleeve is larger than the projection area of the sleeve along the axial direction of the sleeve.

[0007] Optionally, an annular marking line is provided on the surface of the force-bearing portion facing away from the sleeve;

[0008] The projection of the annular marking line along the axial direction of the sleeve coincides with the outer contour line of the first end; or the projection of the annular marking line along the axial direction of the sleeve is located inside the outer contour line of the first end.

[0009] Optionally, the force-bearing portion has a flange, the flange protrudes from the sleeve along the radial direction of the sleeve, and the flange surrounds the sleeve along the circumference of the sleeve.

[0010] Optionally, the bearing adapter sleeve removal tool further includes a plurality of reinforcing ribs, which are arranged at intervals along the circumference of the sleeve, and each of the reinforcing ribs is connected between the flange and the outer circumferential surface of the sleeve.

[0011] Optionally, the outer diameter of the first end is greater than that of the second end, and the outer diameter of at least part of the sleeve gradually decreases from the first end to the second end, and the maximum outer diameter of the sleeve is smaller than the inner diameter of the bearing.

[0012] Optionally, the sleeve includes a constant diameter section and a variable diameter section, an end of the constant diameter section away from the variable diameter section is the first end, and an end of the variable diameter section away from the constant diameter section is the second end;

[0013] The cross section of the diameter-changing section is trapezoidal, and the outer diameter of the diameter-changing section gradually decreases along the direction from the end of the diameter-changing section close to the constant diameter section to the end of the diameter-changing section away from the constant diameter section;

[0014] The cross section of the constant diameter section is square, and the outer diameter of the constant diameter section is equal to the outer diameter of the end of the variable diameter section close to the constant diameter section.

[0015] Optionally, the force-bearing portion is a force-bearing plate, the first end of the sleeve is a closed end, and the force-bearing plate covers the closed end and is connected to the closed end.

[0016] Optionally, the inner diameter of the sleeve gradually decreases along the direction from the second end to the first end.

[0017] Optionally, the end surface of the second end is covered with a rubber pad.

[0018] Optionally, the length of the sleeve is 1000mm-1200mm.

[0019] Through the above technical solution, the sleeve can cooperate with the striking tool to concentrate the force of removing the bearing adapter sleeve on the bearing adapter sleeve itself. By pushing the bearing adapter sleeve out of the bearing, the gap between the bearing and the shaft is increased, thereby reducing the difficulty of disassembling the bearing and facilitating subsequent bearing disassembly. In addition, because the projected area of the force-bearing portion along the axial direction of the sleeve is larger than the projected area of the sleeve along the axial direction of the sleeve, when the striking tool is used to strike the sleeve, the force-bearing portion can shield the operator's hand located on the side of the force-bearing portion away from the striking tool, thereby preventing the striking tool from damaging the operator's hand. In addition, the projected area of the force-bearing portion along the axial direction of the sleeve being larger than the projected area of the sleeve along the axial direction of the sleeve can also increase the force-bearing surface of the force-bearing portion, thereby reducing the accuracy requirements of the striking.

[0020] Other features and advantages of the present disclosure will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0028] In this disclosure, unless otherwise indicated, directional terms such as "upper" and "lower" are generally defined relative to the operating state of a bearing adapter sleeve removal tool. These terms are used solely for ease of description and simplification, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, structure, or operation.

Furthermore, the terms "first" and "second," etc., are used solely for distinction and should not be construed as indicating or implying relative importance.

[0029] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed," "connected," "connected," and "installed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections via an intermediary. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0030] The bearing adapter sleeve can fill the gap between the bearing and the shaft and is used to fix the bearing on the shaft. However, during the disassembly of the bearing, if the bearing adapter sleeve is too tight, it will make the disassembly of the bearing difficult.

[0031] In view of this, if Figures 1 to 3As shown, the present disclosure provides a bearing adapter sleeve removal tool 100, including a sleeve 1, the outer diameter of the sleeve 1 is smaller than the inner diameter of the bearing, the sleeve 1 includes a first end 11 and a second end 12 opposite to each other, the first end 11 is provided with a force-bearing portion 13, the force-bearing portion 13 is used for being struck by a striking tool, the second end 12 has an opening 14 for a shaft to extend into the sleeve 1, and the end surface of the second end 12 is used to abut against the end surface of the bearing adapter sleeve mounted on the shaft.

[0032] The projection of the force-bearing portion 13 along the axial direction of the sleeve 1 covers the projection of the sleeve 1 along the axial direction of the sleeve 1 , and the projection area of the force-bearing portion 13 along the axial direction of the sleeve 1 is larger than the projection area of the sleeve 1 along the axial direction of the sleeve 1 .

[0033] During the bearing disassembly process, the sleeve 1 can be put on the shaft through the opening 14, and the end surface of the second end 12 of the sleeve 1 can be pressed against the end surface of the bearing adapter sleeve. The force-bearing part 13 at the first end 11 of the sleeve 1 can be struck by a striking tool (such as a hammer) to make the bearing adapter sleeve disengage from the gap between the shaft and the bearing and be pushed out of the bearing, thereby facilitating the subsequent disassembly of the bearing.

[0034] Through the above technical solution, the sleeve 1 can cooperate with the striking tool to concentrate the force of removing the bearing adapter sleeve on the bearing adapter sleeve itself. By pushing the bearing adapter sleeve out of the bearing, the gap between the bearing and the shaft is increased, thereby reducing the difficulty of disassembling the bearing and facilitating the subsequent disassembly of the bearing. In addition, since the projected area of the force-bearing portion 13 along the axial direction of the sleeve 1 is larger than the projected area of the sleeve 1 along the axial direction of the sleeve 1, when the striking tool is used to strike the sleeve 1, the force-bearing portion 13 can shield the operator's hand located on the side of the force-bearing portion 13 away from the striking tool, thereby preventing the striking tool from damaging the operator's hand. In addition, the projected area of the force-bearing portion 13 along the axial direction of the sleeve 1 is larger than the projected area of the sleeve 1 along the axial direction of the sleeve 1, which can also increase the force-bearing surface of the force-bearing portion 13, thereby reducing the accuracy requirements of the striking.

[0035] Alternatively, as Figure 2As shown, an annular marking line 15 is provided on the surface of the force-bearing portion 13 facing away from the sleeve 1. The projection of the annular marking line 15 along the axial direction of the sleeve 1 coincides with the outer contour line of the first end 11; or, the projection of the annular marking line 15 along the axial direction of the sleeve 1 is located on the inner side of the outer contour line of the first end 11. The surface of the force-bearing portion 13 facing away from the sleeve 1 can be constructed as a force-bearing surface, that is, the surface used for knocking by the knocking tool. The annular marking line 15 is provided on this surface to mark the position and range of the first end 11 of the sleeve 1. When the knocking tool is used for knocking, the landing point of the knocking tool can be controlled to be as close as possible to the range circled by the annular marking line 15. In this way, it can be ensured that most of the knocking force generated by the knocking tool can be transmitted to the bearing adapter sleeve through the sleeve 1. In addition, the annular marking line 15 serves as an identification and can also prevent the knocking tool from injuring the operator's hand due to hitting off-center.

[0036] Alternatively, as Figure 1 and Figure 2 As shown, the force-bearing portion 13 has a flange 131, which protrudes from the sleeve 1 in the radial direction of the sleeve 1 and surrounds the sleeve 1 circumferentially. The flange 131 protruding in the radial direction and surrounding the sleeve 1 circumferentially can increase the force-bearing area of the force-bearing portion 13, thereby increasing the number of landing points for the striking tool and reducing the difficulty of striking. In addition, the flange 131 can also protect the hand of the operator on the side of the force-bearing portion 13 away from the striking tool. For example, in order to ensure that the sleeve 1 does not shake during the striking process, the operator can hold the sleeve 1 by hand. At this time, the flange 131 can protect the operator's hand from being harmed by the striking tool.

[0037] In order to extend the life of the flange 131, optionally, as Figure 1 and Figure 2 As shown, the bearing adapter sleeve removal tool 100 further includes a plurality of reinforcing ribs 2, which are spaced apart along the circumference of the sleeve 1, and each reinforcing rib 2 is connected between the flange 131 and the outer circumferential surface of the sleeve 1. The plurality of reinforcing ribs 2 provided between the flange 131 and the outer circumferential surface of the sleeve 1 provide support when the flange 131 is struck by a striking tool, thereby preventing deformation of the flange 131 due to lack of support when subjected to force.

[0038] Alternatively, as Figure 1 and Figure 2 As shown, the outer circumferential surface of the sleeve 1 is further provided with a plurality of reinforcing ribs 3, which extend in the axial direction of the sleeve 1 and are spaced apart along the circumference of the sleeve 1. When the sleeve 1 is struck with a striking tool, the sleeve 1 may be subjected to forces from different directions. The provision of the plurality of reinforcing ribs 3 on the outer circumferential surface of the sleeve 1 can strengthen the strength of the sleeve 1 itself, thereby preventing the sleeve 1 from deforming or bending under uneven force.

[0039] In order to facilitate the matching of the sleeve 1 and the bearing adapter sleeve, optionally, as Figure 1 and Figure 2 As shown, the outer diameter of the first end 11 is greater than that of the second end 12. The outer diameter of at least a portion of the sleeve 1 gradually decreases from the first end 11 to the second end 12, and the maximum outer diameter of the sleeve 1 is smaller than the inner diameter of the bearing. Because the first end 11 of the sleeve 1 is provided with a force-bearing portion 13, and the end surface of the second end 12 of the sleeve 1 is used to abut the end surface of the bearing adapter sleeve, the outer diameter of the first end 11 is set to be greater than the outer diameter of the second end 12, and the maximum outer diameter of the sleeve 1 is smaller than the inner diameter of the bearing. This arrangement increases the force-bearing area of the force-bearing portion 13 while ensuring that the end surface of the second end 12 can abut the end surface of the bearing adapter sleeve without abutting the end surface of the bearing.

[0040] In one embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the sleeve 1 includes a constant diameter section 16 and a reducing section 17. The end of the constant diameter section 16 away from the reducing section 17 is a first end 11, and the end of the reducing section 17 away from the constant diameter section 16 is a second end 12. The reducing section 17 has a trapezoidal cross-section, and the outer diameter of the reducing section 17 gradually decreases from the end of the reducing section 17 closer to the constant diameter section 16 to the end of the reducing section 17 farther from the constant diameter section 16. The constant diameter section 16 has a square cross-section, and the outer diameter of the constant diameter section 16 is equal to the outer diameter of the end of the reducing section 17 closer to the constant diameter section 16.

[0041] In order to ensure that the second end 12 of the sleeve 1 can abut against the end face of the bearing adapter sleeve without abutting against the end face of the bearing, it is necessary to ensure that the outer diameter of the second end 12 abutting against the bearing adapter sleeve is smaller than the inner diameter of the bearing, and the force-bearing portion 13 of the first end 11 has a larger force-bearing area to reduce the difficulty of knocking. Therefore, the sleeve 1 can be divided into the above-mentioned variable diameter section 17 and the equal diameter section 16, which are processed separately and then connected. While meeting the above requirements, the processing difficulty of the sleeve 1 can also be reduced.

[0042] In another embodiment, the entire cross-section of the sleeve 1 may be trapezoidal, that is, the entire sleeve 1 is a frustoconical sleeve.

[0043] Alternatively, as Figure 1 and Figure 2 As shown, the force-bearing portion 13 is a force-bearing plate, the first end 11 of the sleeve 1 is a closed end, and the force-bearing plate covers the closed end and is connected to the closed end. The force-bearing plate can increase the force-bearing area of the force-bearing portion 13, and the first end 11 of the sleeve 1 is a closed end, the force-bearing plate covers the closed end, and the closed end can serve as a support for the force-bearing plate, further improving the structural strength and service life of the force-bearing portion 13. In other embodiments, the first end 11 of the sleeve 1 can also be an open end, and the force-bearing plate covers the open end and is connected to the end face of the first end 11.

[0044] Here, it should be noted that the present disclosure does not limit the specific shape of the load-bearing plate. For example, the load-bearing plate can be one of rectangular, circular and triangular. In one embodiment provided by the present disclosure, the load-bearing plate is circular.

[0045] In order to reduce the shaking of the sleeve 1 due to the knocking force, optionally, as Figure 3 As shown, the inner diameter of the sleeve 1 gradually decreases from the second end 12 to the first end 11. During use, the sleeve 1 may experience radial wobble as the striking tool strikes the shaft. By gradually decreasing the inner diameter of the sleeve 1 from the second end 12 to the first end 11, the gap between the inner wall of the sleeve 1 and the outer circumference of the shaft can be reduced while ensuring that the sleeve 1 can be fitted onto the shaft. This allows the inner wall of the sleeve 1 to abut against the outer circumference of the shaft, thereby reducing radial wobble and ensuring the stability of the sleeve 1 during use.

[0046] Alternatively, as Figure 1 and Figure 3 As shown, the end surface of the second end 12 is covered with a rubber pad 4. Since the end surface of the second end 12 abuts against the end surface of the bearing adapter sleeve during use of the sleeve 1, and the bearing adapter sleeve is also impacted by the end surface of the second end 12 of the sleeve 1 as a result of the striking tool, covering the end surface of the second end 12 with the rubber pad 4 can cushion the impact force exerted by the second end 12 on the end surface of the bearing adapter sleeve, thereby protecting the bearing adapter sleeve from damage.

[0047] Optionally, the length of sleeve 1 is 1000mm-1200mm. Since bearings are typically installed on the side of the shaft closest to the spindle head, removing the bearing adapter sleeve requires striking the bearing from the side away from the spindle head. Setting the length of sleeve 1 to 1000mm-1200mm ensures that sleeve 1 is long enough to fit through the other end of the shaft and push out the bearing adapter sleeve, ensuring that sleeve 1 fits the device's dimensions.

[0048] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0049] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0050] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
