Description

Technical Field

[0001] The utility model relates to the technical field of bearing disassembly, in particular to an adjustable bearing disassembly and assembly tool. Background Art

[0002] Bearing removal is a common and important task during the maintenance and repair of mechanical equipment. Ball bearings, widely used components in mechanical equipment, are characterized by a ball positioned between an inner and outer ring. The balls are positioned by a protective cage, and the inner and outer ring sidewalls are not aligned. The cage is aligned with the inner ring and is shorter than the outer ring, resulting in a concave bottom surface. This unique structural design reduces friction and improves rotational efficiency during operation.

[0003] However, disassembling such bearings is a challenging task. Traditional methods, due to uneven force applied during bearing removal, can easily damage the bearing, hindering its reuse. Furthermore, traditional bearing removal tools are typically only suitable for bearings of specific sizes, requiring different tools for different bearing sizes, which not only increases costs but also reduces work efficiency.

[0004] In order to solve these problems, the utility model proposes an adjustable bearing removal tool, which can adapt to bearing sizes within a certain range and can minimize damage to bearings and shafts during the removal process, thereby improving removal efficiency and bearing reuse rate.

[0005] For this purpose, we propose an adjustable bearing disassembly and assembly tool. Utility Model Content

[0033] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0034] like Figure 1-Figure 3 Figure 1 shows the main structure of the adjustable bearing removal tool of the present invention. The tool primarily comprises a first partition plate 1, a second partition plate 2, a first locating pin 33, a second locating pin 4, an eyebolt 5, a flange nut 6, an adjusting tile 7, and a support plate 8. The following details the specific structure and function of each component, as well as how they work together to achieve efficient and non-destructive bearing removal.

[0035] The first partition plate 1 and the second partition plate 2 can be separated and installed on the outer ring of the bearing to clamp and position the bearing, and the opposite sides of the two partition plates are provided with recesses that match the bearings;

[0036] A first positioning pin 3 is fixed on one of the partition plates to provide a reference for the positioning and alignment of the partition plates;

[0037] Two second positioning pins 4 are fixed to the second partition plate 2;

[0038] There are two eyebolts 5 connected to the second positioning pins 4, which can be rotated and engaged with the end surface of the first partition plate 1 and pre-tightened by the flange nuts 6 to improve the connection effect between the two partition plates;

[0039] The adjusting tile 7 is detachably connected to the notch provided in the partition plate. By adjusting its thickness, the tool can be adapted to the removal of bearings of various sizes.

[0040] The supporting plate 8 is on the bottom wall of the recess of the partition plate, and a step groove 801 is provided on the supporting plate to support the bottom wall of the bearing during the disassembly process.

[0041] The first and second partition plates 1 and 2 are the core components of this invention. They can be separated and installed on the bearing outer ring to clamp and position the bearing. Each of the first and second partition plates 1 and 2 has recesses that fit the bearings, and the bottom walls of these recesses are connected to a support plate 8 that supports the bearings. In this embodiment, the support plate 8 is integrally formed with the partition plates.

[0042] The support plate 8 is also provided with a stepped groove 801 that mates with the bearing to be removed, making it particularly suitable for removing ball bearings. This design ensures close contact between the removal tool and the bearing, thereby evenly distributing the force during the removal process and preventing damage to the bearing.

[0043] A first locating pin 3 is fixed to one of the partitions and has a corresponding mounting hole in the other partition. The first locating pin 3 is tightly fitted into the mounting hole and serves to provide a reference for aligning the partitions and ensuring proper installation of the disassembly tool. During disassembly, the first locating pin 3 ensures that the first and second partitions 1 and 2 maintain their correct positional relationship, preventing them from shifting or misaligning when subjected to force.

[0044] In this embodiment, the first positioning pin 3 is fixed on the second partition plate 2, and the diameter of the first positioning pin 3 at one end close to the first partition plate 1 is smaller, and the diameter of the end close to the second partition plate 2 is larger, thereby improving the alignment effect and the tight fit effect.

[0045] Second locating pin 4, fixed to second partition plate 2, not only serves as a positioning mechanism but also provides support for the installation of eyebolt 5 and withstands the tensioning force transmitted by the eyebolt. This design ensures that eyebolt 5 is securely connected to the removal tool, ensuring that it will not loosen or fall off due to the force during the removal process.

[0046] The eyebolt 5 is connected to the second positioning pin 4, and grooves are provided on both sides of the two partition plates 1 to facilitate the rotation of the eyebolt 5. The guide ring bolt 5 rotates with the second positioning pin 4 on the second partition plate 2 as a fulcrum, and can be engaged with the end face of the first partition plate 1 along the groove, and a flange nut 6 is threadedly connected to the other side of the eyebolt 5. The flange nut 6 has a gasket. The flange nut 6 rotates on the eyebolt 5 and is pre-tightened with the corresponding partition plate 1, thereby improving the connection effect between the two partition plates, and then being able to engage the bearing.

[0047] Adjustment pad 7 is another key component of the present invention. It is removably attached to a notch in the divider plate. Adjustment pad 7 can be adjusted to suit the bearing size. By adjusting the thickness of adjustment pad 7, the tool can accommodate the removal of bearings of various sizes. This design enhances the versatility and flexibility of the removal tool, eliminating the need to prepare separate removal tools for different bearing sizes, thereby reducing costs and improving work efficiency.

[0048] In practical application, when using the present invention to disassemble a bearing, first align the two partitions using the first locating pin 3 and fit the upper partition over the outer edge of the bearing. Then, rotate the eyebolt 5 to connect the two partitions. Then, use the flange nut 6 to bring the two partitions closer together and clamp the bearing. At this point, the bearing is securely held in the disassembly tool, ready for disassembly. Then, by securing the shaft, a drive device applies an axial force to the disassembly tool of this embodiment, thereby removing the bearing from the shaft.

[0049] In the present embodiment, the two partition plates, the positioning pin and the eyebolt 5 are all made of high-strength, wear-resistant materials. For example, they can be made of materials such as alloy steel or stainless steel to ensure that they can withstand greater force and wear during disassembly.

[0050] Once disassembly is complete, simply loosen the flange nut 6 and rotate the eyebolt 5 to separate the first and second partition plates 1 and 2, allowing the bearing to be removed from the removal tool. The close contact and even force distribution between the removal tool and the bearing prevent damage to the bearing during disassembly. Furthermore, since the removal tool can be disassembled without completely removing the flange nut 6, the disassembly process is quicker and more efficient.

[0051] like Figure 3Shown is a schematic diagram of a support plate 8 for dragging the bearing bottom out of the upper partition plate. This design is a major innovation of the present invention, thereby improving disassembly efficiency and protecting the bearing from damage.

[0052] Support plate 8 is provided with a stepped groove 801. This slightly raised groove 801 matches the concave bottom surface of the bearing. Based on the characteristics of ball bearings, the center portion of the groove is concave. This design allows the inner ring of the bearing to fit better with the separator plate, facilitating separation of the bearing from the shaft. During disassembly, support plate 8 supports the bottom wall of the bearing, providing additional support and preventing damage due to uneven force during disassembly.

[0053] If the support plate 8 is set horizontally, in actual use, the support plate 8 will always contact the outer ring of the bearing (ball bearing, spherical bearing) but not the inner ring of the bearing. When the driving equipment drives the bearing to move axially along the shaft, the instantaneous force is very large. At this time, the inner ring will receive a large inertial force due to lack of support, thereby causing the inner and outer rings of the bearing and the protective frame to loosen, and in severe cases, the inner and outer rings of the bearing may detach.

[0054] The disassembly tool of the present invention can solve this problem well. It can adapt to bearing inner and outer rings of different heights through the design of the supporting plate 8 and the step groove 801, thereby achieving efficient and non-destructive disassembly.

[0055] In practice, when using this utility model to dismantle a bearing, the user simply places the dismantling tool over the outer ring of the bearing and securely connects them using the locating pin and eyebolt. The dismantling tool is then clamped to the bearing using the flange nut. The support plate 8 supports the bottom wall of the bearing and provides additional support. Due to the close contact and even force distribution between the dismantling tool and the bearing, as well as the additional support provided by the support plate 8, the bearing is protected from damage during dismantling. Furthermore, since there is no need to replace different dismantling tools for bearings of different sizes, the use of this utility model can significantly improve work efficiency and reduce costs.

[0056] In summary, the adjustable bearing removal tool provided by this utility model has broad application prospects and practical value in the field of mechanical maintenance. It not only improves bearing removal efficiency and protects bearings from damage, but also reduces maintenance costs and improves work efficiency. Therefore, this utility model is a very valuable innovation for the mechanical equipment maintenance and repair industry.

[0057] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.
