Description

Technical Field

[0001] This application relates to the technical field of bearing disassembly, and in particular to an auxiliary tooling and tool kit for disassembling mounted bearings. Background Technology

[0002] Mounted bearings, as a common standardized mechanical component, provide stable support for the roller shafts in conveying equipment, reduce friction during rotation, and ensure efficient and stable operation of the conveying equipment. Mounted bearings are typically filled with lubricating oil to ensure smooth rotation. However, oil stains, dust, and other impurities generated during the operation of the conveying equipment easily mix with the lubricating oil, forming a viscous oil-stain mixture. This mixture gradually adheres to the inner ring surface of the mounted bearing and the mating surface of the roller shaft. Over time, a tight adhesion develops between the mounted bearing and the roller shaft, greatly hindering the disassembly of the mounted bearing.

[0003] In traditional techniques, workers typically need to use a shovel or chisel to pry open the space between the bearing and the mounting plate, creating a gap. Then, a pry bar is inserted into the gap to pry the bearing off the roller shaft, making the disassembly process laborious. Utility Model Content

[0004] Therefore, it is necessary to provide an auxiliary tooling and a set of tools for disassembling mounted bearings to address the problem of laborious disassembly processes in traditional technologies.

[0005] The technical solution is as follows:

[0006] One embodiment provides an auxiliary tooling for disassembling mounted bearings, comprising:

[0007] The cylinder has a first port and a second port that are connected to each other. The cylinder is provided with a first mounting part and a second mounting part. The first port is used for the bearing body to pass into the cylinder so that the bearing body is aligned with the first mounting part and then the bearing body is connected to the first mounting part. The second port is used for the pushing part of the disassembly component to pass into the cylinder so that the pushing part abuts against the roller shaft. The second mounting part is used to connect with the connecting part of the disassembly component.

[0008] In use, the aforementioned auxiliary tooling for disassembling mounted bearings involves fitting a cylindrical body onto the bearing body, allowing the bearing body to pass through the first port. The first mounting part connects to the bearing body to secure the bearing body to the cylindrical body. Subsequently, the pushing part of the disassembly component passes through the second port of the cylindrical body and abuts against the roller shaft located in the middle of the bearing body. The connecting part of the disassembly component connects to the second mounting part of the cylindrical body. When the operator controls the pushing part to move, the cylindrical body can move relative to the roller shaft under the abutment action of the pushing part and the roller shaft, thereby removing the mounted bearing from the roller shaft. Compared with traditional technology, using the aforementioned auxiliary tooling for disassembling mounted bearings to remove the mounted bearing from the roller shaft eliminates the need to pry the mounted bearing off the roller shaft with a pry bar, making the disassembly process less strenuous.

[0009] In one embodiment, the auxiliary tooling for disassembling the bearing with a mounting bracket further includes a mounting component. The first mounting portion has a mounting hole, and the mounting component passes through the mounting hole and is used to connect with the bearing body.

[0010] In one embodiment, the mounting member includes a first threaded portion and a mounting rod. The first threaded portion is disposed on the side wall of the mounting rod, and the mounting rod is used to pass through the mounting hole and the set screw hole of the bearing body so that the first threaded portion is screwed into the set screw hole.

[0011] In one embodiment, at least two mounting holes are provided, and the at least two mounting holes are spaced apart along the circumference of the cylinder. At least two mounting members are provided and are provided in correspondence with the mounting holes.

[0012] In one embodiment, the second mounting portion is provided with a connection opening for the connection portion to pass through.

[0013] In one embodiment, at least two connection openings are provided, and the at least two connection openings are spaced apart along the circumference of the cylinder, and the at least two connection openings are used for at least two connection parts to pass through one-to-one.

[0014] In one embodiment, the connection opening is provided with an abutment wall, the abutment wall has a planar structure, the abutment wall is located on the side of the connection opening near the second port, and the abutment wall is used to abut against the connection part.

[0015] In one embodiment, the connection opening has an arc-shaped opening wall located on the side of the connection opening closer to the first port.

[0016] Another embodiment provides a mounting bracket bearing removal tool kit, the mounting bracket bearing removal tool kit including a removal component and a mounting bracket bearing removal auxiliary tooling as described above. The removal component includes a pushing part, a mounting base, and a connecting part. The pushing part is movably disposed on the mounting base and is used to pass through the second port and abut against the roller shaft. The connecting part is disposed on the mounting base and is used to connect with the second mounting part.

[0017] The aforementioned bearing mounting tool kit includes a cylindrical body fitted onto the bearing body, allowing the bearing body to pass through the first port. A first mounting part connects to the bearing body to secure it to the cylindrical body. Subsequently, the pushing part of the disassembly component passes through the second port of the cylindrical body and abuts against a roller shaft located in the middle of the bearing body. The connecting part of the disassembly component connects to the second mounting part of the cylindrical body. When the operator moves the pushing part, the abutment between the pushing part and the roller shaft causes the cylindrical body to move relative to the roller shaft, thereby removing the bearing mount from the roller shaft. Compared to traditional techniques, using this bearing mounting tool kit to remove the bearing mount from the roller shaft eliminates the need for prying with a crowbar, making the disassembly process less strenuous.

[0018] In one embodiment, the pushing part includes a second threaded part and a push rod. The second threaded part is disposed on the side wall of the push rod. The mounting base has a screw hole. The push rod passes through the screw hole so that the second threaded part is screwed into the screw hole. One end of the push rod is used to pass through the second port and abut against the roller shaft.

[0019] In one embodiment, the connecting part includes a claw arm and a claw hook, the claw arm being movably disposed on the mounting base, and the claw hook being disposed on the claw arm and used for connection with the second mounting part. Attached Figure Description

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0033] Please see Figure 2 The mounted bearing provides stable support for the roller shaft 50 of the conveying equipment, thereby reducing the friction of the roller during rotation and ensuring the efficient and stable operation of the conveying equipment. Specifically, the mounted bearing includes a bearing housing 40 and a bearing body 30. The bearing housing 40 is set on the mounting plate 60 of the conveying equipment, and the bearing body 30 is set on the bearing housing 40. The roller shaft 50 of the conveying equipment passes through the mounting plate 60 and the bearing housing 40 in sequence and is assembled with the bearing body 30.

[0034] Furthermore, the bearing body 30 includes an outer bearing ring 31 and an inner bearing ring 32. The outer bearing ring 31 is disposed on the bearing housing 40, and the inner bearing ring 32 can rotate relative to the outer bearing ring 31. The roller shaft 50 passes through the inner bearing ring 32. With the rotational cooperation of the inner bearing ring 32 and the outer bearing ring 31, the roller shaft 50 can rotate stably.

[0035] However, during the operation of the conveying equipment, oil stains and dust are generated, which can easily mix with lubricating oil to form a certain degree of viscosity. This oil stain mixture will gradually adhere to the inner ring surface of the bearing inner ring 32 and the mating surface of the roller shaft 50. Over time, a tight adhesion will form between the seated bearing and the roller shaft 50, which will cause great trouble to the disassembly of the seated bearing.

[0036] Based on this, please refer to Figures 1 to 4 One embodiment of this application provides an auxiliary tooling for disassembling a bearing with a mounting seat, including a cylindrical body 100. The cylindrical body 100 has a first port 111 and a second port 112 that are connected to each other. The cylindrical body 100 is provided with a first mounting part 120 and a second mounting part 130. The first port 111 is used for the bearing body 30 to pass into the cylindrical body 100 so that the bearing body 30 is aligned with the first mounting part 120 and then the bearing body 30 is connected to the first mounting part 120. The second port 112 is used for the pushing part 21 of the disassembly component 20 to pass into the cylindrical body 100 so that the pushing part 21 abuts against the roller shaft 50. The second mounting part 130 is used to connect with the connecting part 22 of the disassembly component 20.

[0037] In use, the aforementioned auxiliary tooling for disassembling mounted bearings involves fitting the cylindrical body 100 onto the bearing body 30, allowing the bearing body 30 to pass through the first port 111. The first mounting part 120 is connected to the bearing body 30 to secure the bearing body 30 to the cylindrical body 100. Subsequently, the pushing part 21 of the disassembly component 20 passes through the second port 112 of the cylindrical body 100 and abuts against the roller shaft 50 located in the middle of the bearing body 30. The connecting part 22 of the disassembly component 20 is connected to the second mounting part 130 of the cylindrical body 100. When the operator controls the pushing part 21 to move, the cylindrical body 100 can drive the bearing body 30 to move relative to the roller shaft 50 under the abutment action of the pushing part 21 and the roller shaft 50, thereby removing the mounted bearing from the roller shaft 50. Compared with traditional technology, using the aforementioned auxiliary tooling for disassembling mounted bearings to remove the mounted bearing from the roller shaft 50 eliminates the need to pry the mounted bearing from the roller shaft 50 with a pry bar, making the disassembly process less strenuous.

[0038] Furthermore, the bearing inner ring 32 of the bearing body 30 protrudes from the bearing seat 40, the cylinder 100 is sleeved on the outer side of the bearing inner ring 32, and the pushing part 21 abuts against the roller shaft 50 in the middle of the bearing inner ring 32, so that the cylinder 100 drives the bearing inner ring 32 to move relative to the roller shaft 50, thereby removing the entire seated bearing from the mounting plate 60 and the roller shaft 50.

[0039] Furthermore, the pusher 21 explains the roller shaft. The cylinder 100 moves along the axial direction of the roller shaft 50 and gradually moves away from the mounting plate 60 to remove the bearing assembly from the mounting plate 60 and the roller shaft 50. This will not be elaborated further here.

[0040] In addition, please see Figure 2 and Figure 4 The bearing housing 40 is connected to the mounting plate 60 by screws. Therefore, when considering removing the bearing from the roller shaft 50, the screws between the bearing housing 40 and the mounting plate 60 must be removed first.

[0041] Please see Figures 1 to 3 In one embodiment, the cylinder 100 is cylindrical in shape, and the first port 111 and the second port 112 are respectively opened at opposite ends of the cylinder 100 and are connected to each other. Thus, when the bearing body 30 passes through the first port 111, the pushing part 21 of the disassembly part 20 passes through the second port 112 and can abut against the roller shaft 50 in the middle of the bearing body 30.

[0042] Furthermore, the first mounting part 120 is disposed near the first port 111, so that when the bearing body 30 passes through the first port 111, the first mounting part 120 near the first port 111 can be connected to the bearing body 30; the second mounting part 130 is disposed near the second port 112, so as to make full use of the space on the cylinder 100.

[0043] For further explanation, please refer to Figure 4 The disassembly component 20 includes a pushing part 21, a mounting base 23, and a connecting part 22. The pushing part 21 is movably disposed on the mounting base 23 and is used to pass through the second port 112 and abut against the roller shaft 50. The connecting part 22 is disposed on the mounting base 23 and is used to connect with the second mounting part 130.

[0044] Optionally, the connection between the first mounting part 120 and the bearing body 30 can be achieved by threaded connection, or by other methods such as bonding or welding, as long as the cylinder 100 can be connected to the bearing body through the first mounting part 120. No specific limitation is made here.

[0045] Optionally, the connection between the second mounting plate 60 and the connecting part 22 of the disassembly part 20 can be made by threaded connection, or by other methods such as bonding or hanging, without specific limitations here.

[0046] Please see Figures 1 to 4 In one embodiment, the auxiliary tooling for disassembling the bearing with a mounting bracket also includes a mounting member 70. The first mounting part 120 has a mounting hole 121, and the mounting member 70 passes through the mounting hole 121 and is used to connect with the bearing body 30.

[0047] Mounting component 70 passes through mounting hole 121 of first mounting part 120 and connects to bearing body 30 to fix first mounting part 120 to bearing body 30, thereby achieving fixation between cylinder 100 and bearing body 30. This method has low implementation cost and reliable fixing effect.

[0048] Furthermore, the mounting component 70 can be a pin or a screw, as long as it can pass through the mounting hole 121 and connect with the bearing body 30. Further details will not be provided here.

[0049] Furthermore, please refer to Figure 1 , Figure 2 as well as Figure 4 The outer wall of the bearing inner ring 32 is provided with a positioning hole, and the mounting part 70 is sequentially inserted into the mounting hole 121 and the positioning hole to fix the sleeve to the bearing inner ring 32.

[0050] Please see Figures 1 to 4 In one embodiment, the mounting member 70 includes a first threaded portion and a mounting rod. The first threaded portion is disposed on the side wall of the mounting rod, and the mounting rod is used to pass through the mounting hole 121 and the set screw hole 33 of the bearing body 30 so that the first threaded portion is screwed into the set screw hole 33.

[0051] The mounting rod passes through the mounting hole 121 and the set screw hole 33 of the bearing body 30 to fix the sleeve to the bearing body 30. The first threaded part on the side wall of the mounting rod can be screwed into the set screw hole 33, thereby effectively preventing the mounting rod from moving along the axial direction of the set screw hole 33 and the mounting hole 121, and ensuring the fixing effect between the sleeve and the bearing body 30.

[0052] Furthermore, the mounting component 70 also includes a screw head, which is located at one end of the mounting rod. The other end of the mounting rod passes through the mounting hole 121 and the set screw hole 33, so that the first threaded portion of the side wall of the mounting rod is screwed into the set screw hole 33. The screw head can abut against the outer edge of the mounting hole 121 on the side away from the set screw hole 33, so as to further ensure the fixing effect between the sleeve and the bearing body 30.

[0053] For explanation, please refer to Figure 2When the transport equipment is working normally, a set screw is inserted into the set screw hole 33. The set screw passes through the set screw hole 33 and abuts against the side wall of the roller shaft 50 to prevent the roller shaft 50 from moving relative to the bearing body 30. In this embodiment, the auxiliary tool for disassembling the bearing with a seat is used by first removing the set screw from the set screw hole 33, and then putting the cylinder 100 on the outside of the bearing body 30. The mounting hole 121 is aligned with the set screw hole 33. Then, the mounting rod is passed through the mounting hole 121 and the set screw hole 33 in sequence. The first threaded part of the side wall of the mounting rod can be screwed into the set screw hole 33 to prevent the mounting rod from moving. The screw head can abut against the outer edge of the mounting hole 121 away from the set screw hole 33 to further ensure the fixing effect between the sleeve and the bearing body 30.

[0054] Please see Figures 3 to 4 In one embodiment, at least two mounting holes 121 are provided, and the at least two mounting holes 121 are arranged at intervals along the circumference of the cylinder 100. The mounting member 70 is provided with at least two and is arranged in a one-to-one correspondence with the mounting holes 121.

[0055] The reliability of the fixation between the sleeve and the bearing body 30 is improved by having at least two mounting pieces 70 pass through the mounting holes 121 in a one-to-one correspondence.

[0056] Furthermore, the number of mounting holes 121 should be equal to the number of set screw holes 33 on the bearing body 30, which will not be elaborated here.

[0057] Please see Figures 3 to 4 In one embodiment, the second mounting portion 130 is provided with a connection opening 131 for the connection portion 22 to pass through.

[0058] The connecting part 22 passes through the connecting opening 131 of the second mounting part 130 to achieve the connection between the connecting part 22 and the cylinder 100.

[0059] Furthermore, when the operator controls the pusher 21 to move, under the contact action between the pusher 21 and the roller shaft 50, the connecting part 22 can abut against the wall of the connecting opening 131, so that the cylinder 100 can drive the bearing body 30 to move relative to the roller shaft 50.

[0060] Please see Figures 3 to 4 In one embodiment, at least two connection openings 131 are provided, and the at least two connection openings 131 are arranged at intervals along the circumference of the cylinder 100. The at least two connection openings 131 are used for at least two connection parts 22 to pass through one-to-one.

[0061] This design improves the connection strength between the disassembly component 20 and the cylinder 100, thereby enhancing the reliability of disassembling the bearing with the seat.

[0062] Please see Figure 3 In one embodiment, the connection opening 131 is provided with an abutment wall 132, which has a planar structure and is located on the side of the connection opening 131 near the second port 112. The abutment wall 132 is used to abut against the connection part 22.

[0063] The planar abutment wall 132 is located on the side of the connecting opening 131 near the second port 112. Thus, when the operator controls the pusher 21 to move, under the abutment action of the pusher 21 and the roller shaft 50, the connecting part 22 can abut against the side of the connecting opening 131 near the second port 112, that is, the connecting part 22 abuts against the abutment wall 132. By setting the abutment wall 132 as a planar structure, the shape of the abutment wall 132 is more in line with the connecting part 22, thereby improving the force flatness between the connecting part 22 and the opening wall of the connecting opening 131, and further improving the disassembly reliability of the bearing seat.

[0064] Please see Figure 1 In one embodiment, the connection opening 131 is provided with an arc-shaped opening wall 133, which is located on the side of the connection opening 131 near the first port 111.

[0065] Compared to a flat opening wall, the arc-shaped opening wall 133 can reduce the area of ​​the connecting opening 131 to a certain extent, thereby increasing the area of ​​the cylinder 100 that can retain the complete material area and improving the overall rigidity of the cylinder 100. In addition, when the disassembly part 20 is a puller, the arc-shaped opening wall 133 can also be adapted to the shape of the back of the claw hook 222 of the puller 20, thereby effectively reducing the mating gap between the claw hook 222 and the connecting opening 131, suppressing loosening, and improving the reliability of disassembly.

[0066] Furthermore, in Figure 1 In the embodiment shown, the connecting opening 131 is provided with an arc-shaped opening wall 133 on the side near the first port 111, and the connecting opening 131 is provided with a planar abutment wall 132 on the side near the second port 112, so that the connecting opening 131 forms a "smiley face" opening. In this way, the reliability during disassembly can be improved while ensuring the overall rigidity of the cylinder 100.

[0067] Another embodiment provides a bearing mounting tool kit, which includes a disassembly component 20 and a bearing mounting auxiliary tool as described above. The disassembly component 20 includes a pushing part 21, a mounting base 23, and a connecting part 22. The pushing part 21 is movably disposed on the mounting base 23 and is used to pass through the second port 112 and abut against the roller shaft 50. The connecting part 22 is disposed on the mounting base 23 and is used to connect with the second mounting part 130.

[0068] The aforementioned bearing mounting tool kit includes a cylindrical body 100 fitted onto a bearing body 30, allowing the bearing body 30 to pass through the first port 111. A first mounting portion 120 connects to the bearing body 30 to secure the bearing body 30 to the cylindrical body 100. Subsequently, the pushing portion 21 of the disassembly component 20 passes through the second port 112 of the cylindrical body 100 and abuts against the roller shaft 50 located in the middle of the bearing body 30. The connecting portion 22 of the disassembly component 20 connects to the second mounting portion 130 of the cylindrical body 100. When the operator controls the pushing portion 21 to move, the cylindrical body 100 can move the bearing body 30 relative to the roller shaft 50 due to the abutment between the pushing portion 21 and the roller shaft 50, thereby removing the bearing mount from the roller shaft 50. Compared to traditional techniques, using the aforementioned bearing mounting tool kit to remove the bearing mount from the roller shaft 50 eliminates the need for prying with a crowbar, making the disassembly process less strenuous.

[0069] Please see Figure 4 In one embodiment, the pushing part 21 includes a second threaded part 211 and a push rod 212. The second threaded part 211 is provided on the side wall of the push rod 212. The mounting base 23 has a screw hole. The push rod 212 passes through the screw hole so that the second threaded part 211 is screwed into the screw hole. One end of the push rod 212 is used to pass through the second port 112 and abut against the roller shaft 50.

[0070] Workers can control the push rod 212 to move along the axis of the screw hole by rotating the push rod 212, thereby adjusting the position of the push rod 212 relative to the mounting base 23. This changes the relative position between the push rod 212 and the connecting part 22, allowing the connecting part 22 to move the sleeve and the bearing body 30, thus removing the bearing with seat from the roller shaft 50. This setup is cost-effective and labor-saving in the disassembly process.

[0071] Please see Figure 4 In one embodiment, the connecting part 22 includes a claw arm 221 and a claw hook 222. The claw arm 221 is movably disposed on the mounting base 23, and the claw hook 222 is disposed on the claw arm 221 and is used to connect with the second mounting part 130.

[0072] The claw arm 221 is movably mounted on the mounting base 23, thereby driving the claw hook 222 to move and connecting the claw hook 222 to the second mounting part 130.

[0073] Furthermore, the claw hook 222 passes through the connection opening 131 on the second mounting part 130 to achieve the connection between the claw hook 222 and the cylinder 100.

[0074] Furthermore, the claw hook 222 is provided with a hook groove, the shape of which matches the shape of the abutment wall 132 of the connection port, thereby improving the flatness of the force when the claw hook 222 hooks the connection opening 131.

[0075] Please see Figure 4 In one embodiment, the disassembly component 20 is a puller.

[0076] Furthermore, depending on the number of connection ports, pullers with different numbers of pull claws can be selected, for example, in Figure 4 In the embodiment shown, there are three connection ports, which are spaced apart around the circumference of the cylinder 100. In this case, a three-jaw puller is selected as the disassembly component 20. The three claw hooks 222 of the three-jaw puller extend into the connection port and abut against the interface wall 132, thereby driving the bearing body 30 to move relative to the roller shaft 50, and then removing the bearing with seat from the roller shaft 50.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
